PUTTING UP STOVES.
BY MARK TWAIN.
We do not remember the exact date of the invention of stoves, but it was
some years ago. Since then mankind have been tormented once a year, by
the difficulties that beset the task of putting them up, and getting the
pipes fixed. With all our Yankee ingenuity no American has ever invented
any method by which the labor of putting up stoves can be lessened. The
job is as severe and vexatious as humanity can possibly endure, and gets
more so every year.
Men always put their stoves up on a rainy day. Why, we know not; but we
never heard of any exception to this rule. The first step to be taken is
to put on a very old and ragged coat, under the impression that when he
gets his mouth full of plaster it will keep the shirt bosom clean. Next,
the operator gets his hand inside the place where the pipe ought to go,
and blacks his fingers, and then he carefully makes a black mark down
the side of his nose. It is impossible to make any headway, in doing
this work, until this mark is made down the side of the nose. Having got
his face properly marked, the victim is ready to begin the ceremony.
The head of the family--who is the big goose of the sacrifice--grasps
one side of the bottom of the stove, and his wife and the hired girl
take hold of the other side. In this way the load is started from the
woodshed toward the parlor. Going through the door, the head of the
family will carefully swing his side of the stove around and jam his
thumb nail against the door post. This part of the ceremony is never
omitted. Having got the family comfort in place, the next thing is to
find the legs. Two of these are left inside the stove since the spring
before. The other two must be hunted after, for twenty-five minutes.
They are usually found under the coal. Then the head of the family holds
up one side of the stove while his wife puts two of the legs in place,
and next he holds up the other while the other two are fixed, and one of
the first two falls out. By the time the stove is on its legs he gets
reckless, and takes off his old coat, regardless of his linen.
Then he goes for the pipe and gets two cinders in his eye. It don't make
any difference how well the pipe was put up last year it will always be
found a little too short or a little too long. The head of the family
jams his hat over his eyes and taking a pipe under each arm goes to the
tin shop to have it fixed. When he gets back, he steps upon one of the
best parlor chairs to see if the pipe fits, and his wife makes him get
down for fear he will scratch the varnish off from the chairs with the
nails in his boot heel. In getting down he will surely step on the cat,
and may thank his stars that it is not the baby. Then he gets an old
chair and climbs up to the chimney again, to find that in cutting the
pipe off, the end has been left too big for the hole in the chimney. So
he goes to the woodshed and splits one side of the end of the pipe with
an old axe, and squeezes it in his hands to make it smaller.
Finally he gets the pipe in shape, and finds the stove does not stand
true. Then himself and wife and the hired girl move the stove to the
left, and the legs fall out again. Next it is to move to the right. More
difficulty now with the legs. Move to the front a little. Elbow not even
with the hole in the chimney, and the head of the family goes again to
the woodshed after some little blocks. While putting the blocks under
the legs, the pipe comes out of the chimney. That remedied, the elbow
keeps tipping over, to the great alarm of the wife. Head of the family
gets the dinner table out, puts the old chair on it, gets his wife to
hold the chair, and balances himself on it to drive some nails into the
ceiling. Drops the hammer on wife's head. At last he gets the nails
driven, takes a wire swing to hold the pipe, hammers a little here,
pulls a little there, takes a long breath, and announces the ceremony
concluded.
Job never put up any stoves. It would have ruined his reputation if he
had. The above programme, with unimportant variations, will be carried
out in many respectable families during the next six weeks.

THE MAGIC LANTERN.
The invention of the magic lantern dates back to 1650, and is attributed
to Professor Kircher, a German philosopher of rare talents and extensive
reputation. The instrument is simple and familiar. It is a form of the
microscope. The shadows cast by the object are, by means of lenses,
focussed upon something capable of reflection, such as a wall or screen.
No essential changes in the principles of construction have been made
since the time of Kircher; but the modern improvements in lenses,
lights, and pictures, have raised the character of the instrument from
that of a mere toy to an apparatus of the highest utility. By its
employment the most wonderful forms of creation, invisible, perhaps, to
the eye, are not only revealed but reproduced in gigantic proportions,
with all the marvelous truth of nature itself. The success of some of
the most celebrated demonstrations of Faraday, Tyndall, Doremus, Morton,
and others, was due to the skillful use of the magic lantern. As an
educator, the employment of this instrument is rapidly extending. No
school apparatus is complete without it; and now that transparencies
are so readily multiplied by photography upon glass, and upon mica, or
gelatin, by the printing press or the pen, it is destined to find
a place in every household; for in it are combined the attractive
qualities of beauty, amusement, and instruction.
The electric light affords, probably, the strongest and best
illumination for the magic lantern; then comes the magnesium light; but
their use is a little troublesome and rather expensive; next to these
in illuminating power is the oxy-hydrogen or Drummond light. The
preparation of the gases and the use of the calcium points involve
considerable skill.
Need has long been felt for some form of the magic lantern, having a
strong light, but more easily produced than any of those just mentioned;
and this has at last been accomplished, after several years' study and
experiment, by Prof. L.J. Marcy, 632 Arch St., Philadelphia, Pa.
The "Sciopticon," is the name of his new instrument, and from actual
trial we find that it possesses many superior qualities. Its lenses
are excellent, and in illuminating power its light ranks next to the
oxy-hydrogen. The sciopticon light is produced from ordinary coal oil
by an ingenious arrangement of double flames, intensifying the heat and
resulting in a pencil of strong white light. Prof. Marcy's instrument
is the perfection of convenience, simplicity, and safety. Any one may
successfully work it and produce the most brilliant pictures upon
the screen. It is peculiarly adapted for school purposes and home
entertainment. Those who wish to do a good thing for young people
should provide one of these instruments. Photographic transparencies of
remarkable places, persons, and objects, may now be purchased at small
cost; while there is no end to the variety of pictures which may be
drawn by hand at home upon mica, glass or gelatin, and then reproduced
upon the screen by the sciopticon.

The Largest Well in the World--Capacity 1,000,000 Gallons of Water per
Day.
One of the grand necessities of the Prospect Park, Brooklyn, N.Y., that
of providing for a continual supply of water for all the purposes of
the Park developed itself, as the Commissioners progressed with their
stupendous undertaking. Mr. Stranahan, the President of the Board, after
carefully weighing the cost, the practicability, and importance
of having an independent water supply for the Park, advised the
Commissioners of the plan which had suggested itself, and the
calculations which had been made by the engineers relative to the
project, and the work was commenced, the first idea being to secure at
least a partial supply of water by means of a well constructed in the
Park. The subject was thus treated in the last annual report of Mr. C.C.
Martin, the engineer in charge:
"This well has been located on the south side of Lookout Hill, near the
lake, and work was commenced upon it late in the season. After a careful
consideration of various methods for sinking the well, it was decided to
build the wall and then to excavate the material from within, trusting
to the weight of the wall to force it down. Sixteen feet of the wall
were laid securely bolted together, before the excavation was commenced.
A derrick with a boom fifty-five feet in length was set up near the
wall, so that the sweep of the boom commanded the interior of it.
Iron buckets containing fourteen cubic feet each were obtained, and a
six-horse power hoisting engine purchased. With these appliances the
excavation was commenced, and carried on with slight interruption until
the work was suspended on account of the frost."
The well is now completed, and is one of the most important features of
the Park. It is worthy to rank as a feat of engineering skill with, any
of the great works of modern times. The Commissioners decided to put its
powers to the test yesterday afternoon, but owing to the unpropitious
weather of the forenoon the trial was postponed. Nevertheless,
Commissioners Stranahan, Fiske, and Haynes, with Mr. Martin, engineer in
charge, and Mr. John Y. Culyer, his assistant, were at the well. During
the last summer some difficulties were encountered in the sinking of the
wall, which were set down by superficial observers as the utter failure
of the enterprise. Mr. Stranahan received but little encouragement from
his fellow Commissioners, some of whom had never seen greater works
of engineering than the construction of street sewers. He assumed the
responsibility of seeing the work through, feeling that the whole thing
depended entirely upon the ability of the engineers, in which he had
abundant faith. All obstacles were surmounted; the work proceeded and
the well is now finished, and so far as is known, is understood to be
the largest one in the world.
The outer wall is fifty feet in diameter, two feet thick, and fifty-four
feet high. The inner curb, or wall, is thirty-five feet in diameter and
two feet thick, having a depth of ten feet. The masonry, as seen from
the top of the structure, is a marvel of neatness and solidity. The
water surface in the well is thirteen feet above high-tide level, and
the depth of water in the well is fourteen feet. The pump foundations
are entirely independent of the walls. This plan was adopted so as to
obviate any possible difficulty which might arise from displacement. The
pump is the Worthington patent, and, with a pressure of forty pounds, is
capable of raising one million gallons of water every twenty-four hours
a height of 176 feet, and is competent to a lift of 180 feet.
The boiler house is a neat, pressed-brick structure trimmed with Ohio
stone, standing on the surface near the mouth of the well. The interior
of the well is reached by a spiral stairway built in the wall, and
commencing in the boiler house. In this way the engineer is able to
reach the pump. It is a fact worthy of notice in connection with the
construction of the wall, or rather the sinking of it, that the outer
wall rests upon four feet of wooden cribwork, two feet thick, and having
an iron shield. The inner wall is built upon a similar crib only two
feet deep, also shielded with iron.
The Commissioners were led to the construction of this well in presence
of the danger at any time of some accident taking place in connection
with the Brooklyn Water Works which would render it necessary for the
Water Board to cut off the Park supply so as to secure the citizens from
suffering. This well has more than the necessary capacity to supply the
Park abundantly with water, yielding most when most is needed. This is
established by the discovery that the time of drought from which the
well is, or may be, likely to suffer, occurs in the Fall. Besides these
facts, it further appears that in order to furnish the supply of water
to the Park the Water Board would have to go through the process of
pumping their water twice to convey it to the required elevation, equal
to 225 feet from its original level.
The work of the well will be to supply the pools at an elevation of 133
feet. From the pools the water is conducted to the lake. Besides this,
there is an independent connection with the lake by which, as necessity
may suggest, the water can be directed to the lake, a lift of only
seventy feet. The lake, when completed, will occupy an area of fifty
acres, which will be kept continually supplied with fresh water, the
arrangements being such, or to be such, as will insure a permanent
change of water, and prevent any of the evils that may arise from
stagnancy. The well is fed from the earth, consisting of a circuit of
two miles, with a fall of five feet to the mile. For this reason it does
not appear easy to exhaust the supply, as when the water is pumped out
to four or five feet from the surface of the well it is replaced at a
rate equal to the demand. Every allowance has been made for evaporation
from the lake and pools, and the supply is regarded as inexhaustible.
Another important fact here suggests itself; that is, that sufficient
rain falls during the season in the area of two miles around the well
to make the supply perennial. The Prospect Park well is a credit to
Brooklyn.--_New York Times_.

PAPER FOR BUILDING.
Our readers will find in another column an advertisement of this new
building material which is now attracting much attention in the West,
and of which we have received very favorable reports. It has been
recently tested in Chicago with the result we are informed of fully
establishing its utility. It is said that a house twenty-two feet long,
sixteen wide, and fourteen high, can be covered on the outside for less
than $9; and a house thirty-six feet by twenty-two, and twenty feet
high, for $20. The building can be done at any season, and can be
finished with great speed, and there are said to be numerous other
advantages connected with the use of the paper. It differs from ordinary
paper in consistency, compactness and solidity. In the manufacture it
is subjected to a pressure of hundreds of tuns, which squeezes out the
liquid matter, leaving a substance of the right thickness. It is said to
be proof against damp and gnawing of vermin, and it being an excellent
non-conductor of heat, must make a warm dwelling in winter and a cool
one in summer. It is used in the place of plastering for inside walls.

The Prussian Government has military maps of every foot of its territory
so complete that every hill, ravine, brooklet, field, and forest is
delineated with perfect accuracy. It is a common boast of Prussian
military men, that within the space of eight days 848,000 men can be
concentrated to the defense of any single point within the kingdom, and
every man of them will be a trained and well-equipped soldier.

Improved Muzzle-Pivoting Gun.
We are indebted for the following able description and criticism of this
Prussian gun to our able contemporary, _The Engineer_.
Viewed as a piece of mechanism, nothing can well be more beautiful
in mutual adaptation of parts to the fulfillment of given and
rather recondite movements, and in point of execution, than this
muzzle-pivoting arrangement of Herr Gruson's; but having said this we
are compelled to add, as impartial engineering critics, that it is
nothing more.
[Illustration: GRUSON'S SYSTEM OF MUZZLE-PIVOTING APPLIED TO MONITORS.]
A very few words of description, aided by the very clear engraving
annexed, will suffice to make the arrangement plain to every mechanical
reader. The entire structure is metallic, chiefly of cast iron or of
steel. Upon the platform of the casemate, or deck of the ship, or
turret, is laid the heavy bed or traverse plate, cast hollow in iron,
holding the vertical pivot at its forward end, on which the gun slide
traverses in azimuth, and at its rear end the segment plate, bolted down
and separately adjustable as to position upon the bedplate. The slide is
also a ponderous hollow casting, the upper surfaces of which, on which
the gun carriage runs forward or recoils, are curvilinear in a vertical
plane, so that the inclination to the horizon is greatest at the rear
end. At the rear end of the slide it traverses upon two heavy cast-iron
turned conical rollers, which are geared together and actuated by the
winch handle and spur gear, seen in our engraving; by these the slide
is practically held fast in any position on the bedplate. The gun
itself--in the model, a steel breech-loader, on the Prussian regulation
system, very slightly modified--is sustained between two high and
ponderous cheek plates of cast iron, which constitute the sides of the
carriage, and which are connected together strongly at the lower edges
by a heavy base or bottom plate, and at the top by two light cross
distance bolts. The muzzle and breech extremities of the piece project
well beyond those cheeks. Along the bottom of the trough of the
carriage, directly under the gun, lies a nearly horizontal hydraulic
press cylinder, the pump and handle actuating which are seen in the
figures to the proper left of the gun, and the supply of water for which
is contained in the hollow bottom of the carriage. On each side cheek of
the carriage is formed, by curved planing, a circular segmental race,
opening inward or toward each other, rectangular in cross section and
into each of which is fitted a segmental block just filling it up, and
occupying a portion of its length so as to slide easily up or downward
through the whole range of the arc or segment.
The center point of the length of each of those blocks carries one side
of the gun, which is connected also with the two heavy radius bars
seen outside the cheeks, and pivoted close to the segment races on the
outside, and with a system of link work between the gun itself and the
crosshead of the ram of the hydraulic cylinder, which gives motion
to the gun in elevation or depression, through a vertical arc, the
imaginary center of which, and of the segments of the side cheeks, is
situated in the horizontal diameter across the muzzle of the gun. This
is in brief the muzzle-pivoting part of the arrangement, of which, were
it worth while to go into its details, we should need some further
diagrams to make it quite clear. Nor is it worth while to go into
the description of various minor points of refinement about the gun
mounting, such as the very exposed long tangent scale seen in the
figure, by which the elevation or depression is read off, nor the still
more exposed and rather ricketty arrangement by which the rear sight
is arranged to rise and fall with the gun, and allowance for dispart
avoided. The recoil of the gun is resisted through and by the segment
blocks in the side cheeks, and by the heavy radius bars, etc., and
thus transferred to the carriage itself. This moves upon four
eccentro-concentric rollers, in all respects identical with those
brought before the Ordnance Select Committee of Woolwich by Mr. Mallet,
in 1858--then rejected, after some time adopted, and brought into use in
our own service, where they are now universal, and from which they have
been adopted into every artillery in the world, and, we understand,
without the slightest recognition of the inventor's rights. On the axle
of each of these rollers is keyed a circular eccentric cam plate, those
at the same side being connected together by a linking bar so as to move
in concert. Adjustable tripping plates attached to the sides of the
slide, are so arranged that when the loaded gun has been run forward its
carriage base rests hard down, with its full weight upon the top faces
of the slide, and thus the recoil is made under the full resistance due
to the friction of the entire load. Arrived at the highest point, it
rests there until loaded. The cam plates being then given a slight
motion of rotation by the help of socket levers--the rectangular
projections to be received by which are seen on the top edges of the cam
plates in the figure--the carriage, by its own commenced descent, gets
again upon its rollers, and runs forward upon these at once into firing
position. The two elevated horns which are seen standing up at the rear
part of the slide above the roller frame are designed to receive the
thump of the two short buffer-blocks--seen at the rear part of each
carriage cheek--in the event of the recoil not being wholly expended in
raising the weight of gun and carriage, etc., along the curved racers
of the slide. These buffer-blocks bear against plugs of vulcanized
india-rubber secured in the bottoms of the buffer cylinders.
We have thus, though very briefly, described the whole of this mounting.
As a carefully thought out and elaborated piece of elegant mechanical
complication Herr Gruson's muzzle-pivoting carriage attracted much
attention at Paris, in 1867, and its merits were regarded as great by
those whose thoughts went little further perhaps. We should have been
glad had it been in our power to have joined in its praise. We are,
however, obliged honestly to say that, however highly creditable to its
designer as an ingenious and capable mechanism, it shows that he has
never realized to himself as a practical artillerist the primary, most
absolute, and indispensable conditions of construction for a serviceable
muzzle-pivoting gun for either land or sea service.
As to the general merits, or general conditions, of muzzle-pivoting,
however, once in doubt at first, these are admitted now by all; and
the latter resolve themselves almost into this--that system of
muzzle-pivoting must be best which, while preserving the essential point
of leaving the muzzle of the gun free of any direct attachment, i.e.,
with an imaginary, not an actual, pivot of vertical arc motion, shall be
_the simplest possible_ in its parts, have the least details, the fewest
parts capable of being struck by splinters or shot, and all its parts of
such materials and character as to receive the smallest amount of injury
if so struck. In every one of these aspects Herr Gruson's mounting is at
fault. With parts and movements far more ingeniously adapted than those
of the crude and unskillfully designed muzzle-pivoting carriages of
Captain Heathorn, also exhibited at Paris, and much exhibited and
exposed since, the Gruson mounting is even more complicated, expensive,
and liable to injury of every sort to which a gun carriage can be
conceived liable. We may even venture to affirm that ponderous as
was the mass of cast iron, etc., in the Paris model carrying only a
12-pounder gun, were it all enlarged in such ratio as might appear to
suit for a 10-inch 25-tun rifled gun of the British type, the almost
proverbial relations, between weight, velocity of impulse, and
brittleness of cast iron, would show themselves, in the whole machine
going to pieces within a very few rounds.

Stock Feeding by Clock Work.
Mr. F. B. Robinson, of North Haven, Conn., has invented a very neat
arrangement, whereby horses or stock can be fed at any time required
with certainty and without personal attention at the time of feeding.
His invention consists of a hopper with a drop bottom in which the
provender is placed. A latch secures the drop bottom, the latch engaging
with a spring catch. A simple arrangement of clock work on the principle
of the alarm clock, may be set to release the spring at any hour or
minute desired, when the drop falls and the provender falls through a
chute into the feeding trough. This invention may be adapted to feeding
any number of horses or cattle, only one clock being required. We regard
the invention as one of much value. By its use much neglect of careless
attendants may be obviated, and a farmer without help, might leave home
for an evening's entertainment, or absent himself on business, without
fear that his stock would suffer. Besides being so convenient the cost
of the apparatus is a mere bagatelle.

Milk, and What Comes of It.
Orange County has long been a laud flowing with milk and--butter. Three
or four of these most beautiful autumn days were spent by us, says a
writer in _Harper's Weekly_, among the farmers which are supposed to
butter our New York city bread, and qualify our tea and coffee. Recent
mechanical improvements have taken away much of the traditional romance
of the farm, but, on the whole, the loss is more than made up by the
gain of perfect system and wonderful adaptation. Instead of four or
five cows, known by such names as Brindle, Bess, and Sukey, milked by
rosy-cheeked maidens, we have now droves of fifty or a hundred, milked
by men, who know them only as "good" or "poor milkers."
In some fine farms a large and luxuriant pasture, with running brooks
and border of woodlands, affords, with the herd feeding in it, a
beautiful picture; and the substantial barns constructed to keep the
cattle comfortably cool in summer and warm in winter, with ample
drinking troughs and stalls for fastening up at night, are indicative of
the good shelter at hand when winter storms drive the cows indoors. To
the farmyards the cows are brought night and morning, in summer, to be
milked. The strained milk is put into large cans holding forty quarts,
such as the milkmen use in distributing it through the city. These cans
are then put into tanks made in some cool running stream, where the
water comes nearly to the top of the can. Frequent stirring is necessary
until the animal heat is quite gone. The milk is then fit to be sent
to the cars. This process can never safely be omitted for, paradoxical
though it may seem, milk is "fresher" and sweeter when it reaches the
consumer if it is delayed at the farm for at least twelve hours. Even
in hot weather, it is more certain to keep sweet when twenty-four or
thirty-six hours elapse between the milking and the using in the city.
There has been much discussion as to the best means of cooling milk
for market, and patent pails have been tried in which the milk passes
directly from the cow through small, coiled tubes surrounded by ice.
But this rapid cooling does not work well, and practical experience
indicates that the old simple process is the best. Every well-appointed
farm must have, therefore, a cool and unfailing stream of water. There
are two such streams in one of the farms we visited. One passes through
the barn, furnishing drinking troughs for the cattle, and a tank for
cooling milk in winter. The other, running through the pasture, supplies
a trout-breeding pond, and furnishes a tank for summer use. In a little
hut under the trees, the milk cans are kept in a stream, which even
the severe drought of last summer did not dry, nor the heat raise to a
temperature of 60 deg..
We are assured most positively that none of the spring water finds its
way over the mouth of the can into the milk. Its dilution, of which
there is so much just complaint, must be done, if at all, in the city,
for the wholesale buyer is said to have such means of testing the milk
as effectually protects him against the farmer. May the man be busy at
work who is to give each family such a protection. We have heard it said
that one end of a small piece of common tape placed in a pan of milk
will carry from it all the water into another vessel in which the other
end of the tape should be placed; but we have never found this a safe
test.
Strange to say, no butter is made on these large milk farms. The supply
for the family is obtained from market, or, more rarely, from a neighbor
who churns all his milk for the accommodation of those who send all
theirs to the city. Our notions of the way to make butter were decidedly
overturned on going to such a dairy. No setting of the milk in shallow
pans for cream to rise; no skimming and putting away in jars until
"churning day," when the thick cream was agitated by a strong arm until
the butter came, then worked and salted. Instead, there is a daily
pouring of the unskimmed soured milk into a common churn, perhaps
somewhat larger than ordinary. The dasher is fastened to a shaft, which
is moved by a crank. The crank is turned by means of a nearly horizontal
wheel some eight or ten feet in diameter, which is kept in motion by a
dog, sheep, or calf standing on it, something after the manner of the
old tread-mill.
When taken from the churn, the butter is worked by hand as of old. The
farmer with whom we have talked said he was about determined to send his
milk to the creamery, since butter-making made it so hard for the women.
Surely woman is less a drudge than she used to be. If, after being
relieved from the labor of churning, the remaining working of the butter
is considered too hard for the farmer's wife, the day of a woman's
redemption must be near at hand.
Only one butter farm, have we been able to find, and not enough is made
there to supply the immediate neighborhood. Where, then, does all the
Orange county butter come from? Mostly from the West. Farmers buy
from the vicinity of the Alleghenies, and even further west, large
quantities, which they sell in the original packages or repack in pails.
Since railroads have become so numerous, New York drinks up all the milk
in Orange county, and must butter her bread elsewhere.
The largest institution for the disposition of milk is the Creamery,
which is, in other words, a cheese factory. Here is brought the milk
which the farmers themselves are unable properly to prepare for market,
for want of cool springs or sufficient help. Received here, it is placed
in deep but narrow tin pails holding twelve or fourteen quartz. These
are floated in large tanks of water. From these pails the cream is
carefully taken and sent to market. The skimmed milk is then placed in
a large vat and heated, by means of steam pipes to about 80 deg.. Then the
rennet is put in. From twenty to thirty minutes suffices for curdling,
and the mass is then stirred to separate the curd from the whey. After
which it is heated still more; and then the whey, passing off through a
strainer, goes to feed hogs, while the curd remains in the vat, to be
salted and worked before putting into the presses. In two or three hours
the curds become hard enough for the canvas to be put upon them ready
for the shelves. Very carefully they must then be watched, lest the
fly lying in wait for them makes in them a snug house for her family.
Greasing and turning must be a daily labor, and some weeks must pass
before they are sufficiently cured for market.
For the benefit of city consumers, who are paying ten and twelve cents a
quart for milk, from a tenth to a quarter of which is not infrequently
pure Croton, we may add that the highest price the farmer ever gets for
his milk is seven cents a quart; and he sometimes sells it for as low as
two cents and a half. Our friends, the milkmen, have, therefore, it will
be seen, a pretty good margin for freight and profit.

Improved Hay Elevator.
The method most generally used for elevating hay is evidently not
the most economical application of the power of horses for the
accomplishment of the purpose desired. The tackle involves a great deal
of friction, and as the quantity which can be thus raised at once is,
probably, on the average, not more than from 150 to 200 lbs, much more
time is employed in re-adjusting the fork, than would be the case if a
larger quantity were elevated.
The invention under consideration supplies a means whereby it is claimed
hay may be unloaded with far greater facility than heretofore, with less
labor to the team and with fewer hands than are at present employed.
A primary gear wheel is propelled horizontally by a lever worked by
a horse. The primary gear impels a pinion keyed to the shaft of a
windlass, upon which is wound the elevating rope, whenever the clutch,
A, is made to operate through the cord and lever, B. This cord runs over
a pulley on the under side the wood framework at C, and its further end
may be held in the hand of the workman on the hay load, who, when he has
properly adjusted the fork, pulls the cord which operates the clutch,
and the "fork-full" of hay is at once elevated. The cylinder of the
windlass, not being keyed to the shaft, only operates when the clutch is
closed by the cord.
The horse, or horses which furnish power to the machine, may, therefore,
keep on traveling in the same direction, and no time is lost in stopping
and backing, as in the method in general use.
[Illustration: DERR'S CAPSTSTAN FOR ELEVATING HAY FORKS.]
There is no doubt but that this is a cheap, durable, and desirable
machine, and one that can be used to great advantage, not only for the
elevation of hay, but for many other purposes. We think it would be
found a decided improvement in discharging cargoes of coal from barges,
and for handling coal in storage yards.
The inventor claims that twice as much hay can be raised in a given time
by its use, as can be done by the old method; and it dispenses with one
hand at the barn or stack.
A coupling at D, enables attachments to be made, which extend the
usefulness of the machine very much. It may be used as a power for
driving wood saws, cutting fuel, thrashing, and other work where a
simple horse power is desirable.

COMPETITORS FOR PRIZES.--The interest that our friends have taken in
obtaining additional names to send with their own subscriptions to the
SCIENTIFIC AMERICAN for the coming year, is without a parallel. The
clubs sent by competitors for the cash prizes are not so many or so
large as we expected, but the number of applicants for the steel plate
engraving exceeds our expectation.

IMPROVEMENT IN LAMP WICKS.
Our engravings show a novel substitute for the cotton lamp wick. The
wick, two forms of which are shown in Figs. 1 and 2, are made of
glass, and are filled preferably with pulverized gypsum, although any
finely-ground stone, mineral, or metal may be employed. The bottom of
the glass tube is closed by wire gauze, or other suitable strainer,
through which the fluid flows; and is carried by the capillary
attraction of the pounded material to the top of the wick.
Thus a permanent wick is obtained, which may be employed with any form
of lamp, and will last for an indefinite time. It may also be used in
connection with an open cup, which the inventor terms a poor man's
lamp. A perforated card is laid upon the top of the cup or tumbler as a
support to the wick.
[Illustration]
It may be used either with or without a chimney, and it is claimed that
with good kerosene oil it is perfectly safe, and consumes less of it,
while it may be also used as a candle.
Patented through the Scientific American Patent Agency, September 14,
1869, by Edward D. Boyd, of Helena, Ark.

Great Transformation.
Seven years ago, says the Port Said correspondence of the London _News_,
there was nothing to distinguish Ismailla or the smiling lake before you
from the rest of the desert, and all was sand. It is the canal which has
raised up the numerous handsome villas and fine gardens. Fresh water is
all that is needed to turn the arid desert into a fruitful soil; and the
supply of this is provided by the subsidary canal which the company
has formed side by side with that broad salt one which now unites two
worlds. Wonderful stories are told of the productiveness of the gardens,
and a walk through any of those belonging to the leading officials
stationed at Ismailla is to verify them all. Vines with large bunches of
grapes pendent from their branches; orange trees with green fruit just
showing a golden tint; ivy, roses, geraniums from England, and an
endless variety of rich tropical plants are all flourishing. In the
centre of the town is a square with trees and a building clothed with
rich creepers in its midst. Everything here looks French. A handsome
boulevard runs down to the point of embarkation, the streets and squares
are on the true Parisian model, and there are _cafes_, billiard rooms,
and _cafe chantants_ which might easily belong to Nantes or Lyons. There
are of course huge gaps where the houses and shops will be; the roads
are, many of them, still of sand; camels draw carts, and generally
pervade the place in long strings; but with all this you are kept in a
state of wonder during your stay at Ismailla at the marvelous conversion
which has taken, place under your eyes.

C.H.G., of N.Y.--To make pure nitrate of silver, dissolve pure silver in
pure nitric acid, evaporate the solution to dryness, or, if crystals are
preferred, evaporate until the solution is sufficiently concentrated
to form crystals. If you can not get pure silver, you may purify it by
dissolving coin in nitric acid, filtering the solution and precipitating
the silver in the form of a chloride by hydrochloric acid. Next wash the
precipitate with hot water until the washings cease to redden litmus
paper. Next mix the pure chloride of silver while yet moist with its own
weight of pure crystallized carbonate of soda, place the mixture in a
covered porcelain crucible and heat very gradually until the fusing
point of silver is reached. The reduced silver will be pure and may be
removed by breaking the crucible. Wash the button thoroughly with hot
water to remove the flux. In dissolving the pure silver thus obtained in
nitric acid, it is better to use an excess of acid; the excess will be
driven off by heat in evaporation.
G.B., of Iowa.--Nominal horse power is merely a conventional expression
for diameter of cylinder and length of stroke, and does not apply to the
actual power of the engine. It is found by multiplying the cube root of
the stroke in feet by the square of the diameter in inches and dividing
the product by 47. This rule is based upon the postulate established by
Watt, that the speed of a piston with two feet stroke is 160 feet per
minute, and that for longer strokes the speed varies as the cube roots
of the length of the stroke. It is needless to say this rule is not
observed in modern practice, yet the expression, nominal horse power, is
like many other relics of past time still retained. The above rule does
not apply to high pressure engines. For such engines Bourne has given
the following rule: Multiply the square of the diameter of the cylinder
in inches by the cube root of the stroke in feet, and divide by 15.6.
The real power of an engine is estimated from the mean effective
pressure in the cylinder--not the boiler--and the speed of the piston.
Your data are insufficient to determine the horse power of your boiler.
The horse power of boilers is estimated from the extent of heating
surface when the grate and all other things are correctly proportioned,
but with them as with engines, only actual test will positively
determine it. The pipe you mention ought to be enlarged as proposed.
W.H.R., of Mass.--Pressure acts independently of the mode of
application. A tun laid upon the head of a wedge would produce the same
effect as though it were applied through toggles. When, however, a
weight is dropped its effect increases as the square of its velocity.
J.B., of N.Y.--We recommend you to get "Appleton's Dictionary of
Mechanics." Also send for descriptive catalogue to Henry Carey Baird,
Philadelphia, from which you will be able to judge for yourself what
works are suited to your requirements.
T.D.H., of Mass.--Ammonia, in a weak solution, may be used to cleanse
the scalp, but is not recommended for the purpose. Borax in solution is
better. The supposed preservation of the color of the hair by its use is
a mistake.
F.B.H., of Ill.--So far as we know, nothing better than the flax seed
bag has been discovered for packing the lower end of tubes in artesian
wells. We have never heard of any trouble arising from the method and
think you will have none.
L.G. of Mass.--Express the decimal ratio of the diameter of a circle to
the circumference to which you refer, as a mixed vulgar fraction, and
you will have what you ask for, if we understand your query.
A.H.S., of Sandwich Islands.--We know of no substance that in our
opinion, could be used advantageously to paint the interior of
sheet-iron evaporating pans for concentrating cane juice.
L.B., of Wis.--We would be glad to assist you but the data you furnish
are not sufficient. The accurate solution of such a problem involves the
higher mathematics.
A.H.M.--All animal and mineral oils are destructive to rubber. Linseed
oil will not dissolve it. Oils should not be allowed to get on rubber
belting.
T.W.J., of Pa.--For your rollers try some emery mixed in a solution of
gum shellac in good alcohol.
E.B., of Mass.--The patent can be corrected by reissue.
J.M.T., of Ind.--To find the proper area for a safety valve port, when
the evaporating surface is properly proportioned to the engine power,
multiply the square of the diameter of the piston in inches by the speed
in feet of the piston per minute, and divide the product by 375 times
the pressure on the boiler per square inch. Having decided upon the
length of the lever, the distance of the valve stem from the fulcrum,
and the point from which the weight will be suspended, the weight
necessary will be found by multiplying the area of the valve port in
inches into the pressure per square inch in the boiler in pounds, and
this product into the distance of the center of the valve stem from
the fulcrum in inches, and dividing the product thus obtained by the
distance from the fulcrum to the point of suspension of the weight in
inches. The quotient will give the weight in pounds.
A.K.S., of Ohio.--The inclination of the poles of a planet to the plane
of its orbit, determines its zones and also its seasons. The inclination
of the earth's axis is twenty-three and one half degrees. This places
the tropics the same distance each side of the equator, and the polar
circles the same distance from the poles. The torrid zone is therefore
forty-seven degrees wide, and the temperate zones each forty-three
degrees wide. As the planets vary in their inclination of their axis
to the planes of their orbits, it follows that their zones and seasons
differ from those of the earth.
W.H.C., of Texas.--The teeth of a circular wood saw to be driven by
foot-power, should be not larger than those of the ordinary hand
crosscut. The fly-wheel ought to have a rim weighing from eighty to one
hundred pounds, and it should be, for a 12-inch saw, not less than a
foot in diameter. It should be placed on the saw arbor. The belt should
not run on the fly-wheel, but on a special pulley, and the treadle and
crank motion should be so adjusted that the foot will move through an
arc of from 10 to 12 inches.
A.H.B., of Pa.--We advise you to use a battery in coating the small
gray castings, of which you write, with copper. It will be all the more
satisfactory in the end. The best polishing material to put in with them
in the tumbler we think would be leather cuttings and sweepings.
They will not need returning to the tumbler after being coppered.
We recommend you to get "Byrne's Practical Metalworkers Assistant,"
published by Henry Carey Baird, Philadelphia.
J.H.G., of Tenn.--Don't put oil in your boiler to prevent incrustation.
It will not probably do any good, and it will cause much foaming, while
besides that it is a waste of heat, it is injurious to engines.
S.S.R., of Tenn.--No ammoniacal engines are, so far as we are aware,
running in this country.
C.E.C., of Ohio.--The varnish for patterns is common shellac varnish. It
is sometimes made black by lampblack.

in an improved arrangement of the side rails for extension.
MANUFACTURE OF SCOOPS.--S. Geo. Knapp, Woodhaven, N.Y.--This invention
relates to an improved mode of manufacturing sheet-metal flour, grain,
and other scoops, and consists in forming the bowls in one piece of
metal, without seams or joints, by stamping up sheets of metal into the
form of a trough, with a flange around the top, and cutting the same
transversely in the center, with blanks for the bowls of two scoops, to
be finished by trimming or shaping the cut ends, turning down the flange
at the top, for stiffening either over wire or not and attaching the
handle; the object being to produce scoops with bowls formed in one
piece, and shaped at the base or in the part where the handles are
connected, and to smoothly effect an economy of labor by stamping two
blanks at one blow of the drop press, and also to control the metal
under the action of the drop better in shaping the deep curved part of
the base so as to upset and stiffen the blanks thereat.
BORING MACHINE.--E.C. Barton, Bloomsburg, Pa.--This invention relates to
improvements in wood-boring machines, whereby it is designed to provide
a simple and efficient arrangement of frame operating devices and
feeding table for boring light articles to be presented to the machine

incased within a hasp, and a hook is used in connection with the hasp
for locking, or independently for fastening the door without locking.
WATER WHEELS.--W.J. Thompson, Springfield, Mo.--This invention relates
to improvements in that class of horizontally running wheels, which
receive the water from above or below on curved buckets taking the water
at one side and discharging it at the other, and it consists of an
improved arrangement of vertically oscillating gates, which, when open,
form chutes for the water; it also consists of an improved means for
working the gates.
PIPE COUPLING.--J.D. Ware, Savannah, Ga.--This invention relates to
improvements in pipe couplings, and consists in forming a dovetailed
groove across the end of one part, with an annular recess in the bottom
around the bore for a packing ring, and fitting on the other part a
dovetailed projection for engaging in the groove, and in arranging on
one of the parts an eccentric ring to work against the head of the
projection and force it tightly into the groove.
FIRE GRATES.--G.W. Everhart, Louisville, Ky.--This invention relates to
improvements in that class of fire grates used for heating rooms, and
consists in so arranging them as to provide a clear air space between
the basket and the walls of the fire-place, both at the back and ends,
for the admission of air more directly at these parts, for the better
combustion of the coal and the gases arising therefrom; it also consists
in providing a recess in the hearth or bottom of the fire-place under
the grate, for the reception of ash pans of greater capacity than can be
contained on the top of the hearth, whereby a much larger quantity of
cinders and ashes may be received and retained, so that less frequent
removals of the same will be required.
APPARATUS FOR SEWING SADDLERY AND OTHER LEATHER, OR STRONG
MATERIALS.--Auguste Jacques Hurtu and Victor Joseph Hautin, Paris
France.--This invention relates to apparatus more especially applicable
for sewing leather, saddlery, harness, and other similar work with waxed
thread, and consists first, in the improved apparatus of this invention,
two needles are employed, the one sewing as an awl, and the other
carrying the thread; the two needles have at the same time a vertical
movement and also an adjustable horizontal movement. The needles are
operated alternately, so that the needle may pass the thread through the
hole made just previously by the awl, before the leather has been
moved forward. By this means the sewing may be carried on with great
regularity, and the material be turned in any direction in order to
execute small designs. Secondly, the invention relates to improvements
in the arrangement of the shuttle, whereby it is caused to pass through
the loops formed by the waxed thread without touching it.
PACKING AND ATOMIZING CAN.--F.L. Palmer, Sr., New York city.--This
invention relates to improvements in cans for packing insect powder
and other like finely powdered substances which, in use, require to be
delivered in atomic jets for penetrating crevices where insects secrete
themselves, and it consists in providing such cans with stoppers having
nozzles, through which stoppers or nozzles the passages are temporarily
closed in a way to be readily opened for use; also, in providing the
cans with nozzles at or near the bottom temporarily plugged in which
tubes may be connected so that the powder may, when required for use,
be readily blown out in atomic jets, whereby the said cans are made to
subserve the uses of packing cans and discharging atomizing cans, with
but trifling additional expense, whereas, at the present time, users of
such powders are compelled to buy expensive atomizing cans, to which
the powder must be transferred from the packing cans, before it can be
properly used, or in the absence of such cans the powder is scattered in
an ineffectual and wasteful way in or about the resorts of the insects.
REMEDY TOR RHEUMATISM.--H.H. Munroe, Louisville, Ky.--This invention
relates to a new and useful improvement in a remedy for rheumatism.

U.S. Patent Office
How to Obtain Letters Patent for New Inventions.
Information about Caveats, Extensions, Interferences Designs, Trade
Marks; also, Foreign Patents.
For a period of nearly twenty-five years, MUNN & CO. have occupied the
position of leading Solicitors of American and European Patents, and
during this extended experience of nearly a quarter of a century, they
have examined not less than fifty thousand alleged new inventions, and
have prosecuted upward of thirty thousand applications for patents, and,
in addition to this, they have made, at the Patent Office, over twenty
thousand preliminary examinations into the novelty of inventions, with a
careful report on the same.
The important advantages of MUNN & CO.'S Agency are, that their practice
has been ten-fold greater than that of any other Agency in existence,
with the additional advantage of having the assistance of the best
professional skill in every department, and a Branch Office at
Washington, which watches and supervises, when necessary, cases as they
pass through official examination.
CONSULTATIONS AND OPINIONS FREE.
Those who have made inventions and desire a consultation are cordially
invited to advise with MUNN & CO. who will be happy to see them in
person at the office, or to advise them by letter. In all cases, they
may expect an HONEST OPINION. For such consultations, opinion, and
advice, NO CHARGE is made. A pen-and-ink sketch and a description of the
invention should be sent.
TO APPLY FOR A PATENT,
a model must be furnished, not over a foot in any dimension. Send model
to MUNN & CO., 37 Park Row, New York, by express, charges paid, also, a
description of the improvement, and remit $16 to cover first Government
fee, and revenue and postage stamps.
The model should be neatly made, of any suitable materials, strongly
fastened, without glue, and neatly painted. The name of the inventor
should be engraved or painted upon it. When the invention consists of an
improvement upon some other machine, a full working model of the whole
machine will not be necessary. But the model must be sufficiently
perfect to show with clearness the nature and operation of the
improvement.
PRELIMINARY EXAMINATION
is made into the patentability of an invention by personal search at the
Patent Office, among the models of the patents pertaining to the class
to which the improvement relates. For this special search, and a report
in writing, a fee of $5 is charged. This search is made by a corps of
examiner of long experience.
Inventors who employ us are not required to incur the cost of a
preliminary examination. But it is advised in doubtful cases.
COST OF APPLICATIONS.
When the model is received, and first Government fee paid, the drawings
and specification are carefully prepared and forwarded to the applicant
for his signature and oath, at which time the agency fee is called for.
This fee is generally not over $25. The cases are exceptionally complex
if a higher fee than $25 is called for, and, upon the return of
the papers, they are filed at the Patent Office to await Official
examination. If the case should be rejected for any cause, or objections
made to a claim, the reasons are inquired into and communicated to the
applicant, with sketches and explanations of the references; and should
it appear that the reasons given are insufficient, the claims are
prosecuted immediately, and the rejection set aside, and usually WITHOUT
EXTRA CHARGE TO THE APPLICANT.
MUNN & CO. are determined to place within the reach of those who confide
to them their business, the best facilities and the highest professional
skill and experience.
The only cases of this character, in which MUNN & CO. expect an extra
fee, are those wherein appeals are taken from the decision of the
Examiner after a second rejection; and MUNN & CO. wish to state very
distinctly, that they have but few cases which can not be settled
without the necessity of an appeal; and before an appeal is taken, in
any case, the applicant is fully advised of all facts and charges, and
no proceedings are had without his sanction; so that all inventors who
employ MUNN & CO. know in advance what their applications and patents
are to cost.
MUNN & CO. make no charge for prosecuting the rejected claims of their
own clients before the Examiners and when their patents are granted, the
invention is noticed editorially in the SCIENTIFIC AMERICAN.
REJECTED CASES.
MUNN & CO. give very special attention to the examination and
prosecution of rejected cases filed by inventors and other attorneys. In
such cases a fee of $5 is required for special examination and report,
and in case of probable success by further prosecution, and the papers
are found tolerably well prepared, MUNN & Co. will take up the case and
endeavor to get it through for a reasonable fee, to be agreed upon in
advance of prosecution.
CAVEATS
Are desirable if an inventor is not fully prepared to apply for a
Patent. A Caveat affords protection, for one year, against the issue
of a patent to another for the same invention. Caveat papers should be
carefully prepared. The Government fee on filing a Caveat is $10, and
MUNN & Co.'s charges for preparing the necessary papers are usually from
$10 to $12.
REISSUES.
A patent when discovered to be defective, may be reissued by the
surrender of the original patent, and the filing of amended papers. This
proceeding should be taken with great care.
DESIGNS, TRADE MARKS, AND COMPOSITIONS
can be patented for a term of years, also, new medicines or medical
compounds, and useful mixtures of all kinds. When the invention consists
of a medicine or compound, or a new article of manufacture, or a new
composition, samples of the article must be furnished, neatly put up.
Also, send a full statement of the ingredients, proportions, mode of
preparation, uses, and merits.
PATENTS CAN BE EXTENDED.
All patents issued prior to 1861, and now in force, may be extended for
a period of seven years upon the presentation of proper testimony. The
extended term of a patent is frequently of much greater value than the
first term; but an application for an extension, to be successful,
must be carefully prepared. MUNN & Co. have had a large experience in
obtaining extensions, and are prepared to give reliable advice.
INTERFERENCES
Between pending applications before the Commissioners are managed and
testimony taken; also, Assignments, Agreements, and Licenses prepared.
In fact, there is no branch of the Patent Business which MUNN & Co. are
not fully prepared to undertake and manage with fidelity and dispatch.
FOREIGN PATENTS.
American inventors should bear in mind that five Patents--American,
English, French, Belgian, and Prussian--will secure an inventor
exclusive monopoly to his discovery among ONE HUNDRED AND THIRTY
MILLIONS of the most intelligent people in the world. The facilities of
business and steam communication are such, that patents can be obtained
abroad by our citizens almost as easily as at home. MUNN & Co. have
prepared and taken a larger number of European Patents than any other
American Agency. They have Agents of great experience in London, Paris,
Berlin, and other Capitals.
A Pamphlet, containing a synopsis of the Foreign Patent Laws, sent free.
Address
MUNN & CO., 37 Park Row, New York.
