PREFACE.
Tliis Manual ik adopted, with some necessary changes, omissions, and
alterations, from the Ordnance Manual of the United States service of
1861, prepared under the immediate direction of Major Laidi.ky. The
material of the two 8erA*ices is. of course, nearly identical, differing only
in the shape of the new Columbiads and the Rifle (inns, and the addi-
tion to our service of the Mountain Rifle of 2.25 inch.
It may be added that the labor of Ordnance ofiicers now in the ser-
vice of the Confederate States, has contributed to this new edition of
the United States Manual.

There are, in some of the forts, guns of an older model than the above. The
42-pounder gun, and the 8 and 10-inch sea-coast howitzers, are suppressed by order
of February 9, 1861.
10 ORDNANCE MANUAL.
Some of the R and 10-inch columbiRilo hare been riflp<l : the fir»t to a (•■lihre r>f
6.8 inch; the second, 6.4 inch. Their fre(|uent bnrsting hag caused thiw clans of
rifle gun to be discontinoed. A few of the 8-inch siege h«wit»ers were alto rifled,
for experiment, with a bore of 4.ft2 inch.
Tlic formn of the several pieces of ordnance are shown in the Plates 1, 2. «, 7, »,
10, 11 and 14.
Ounx and howitzers take their denominations from the weights of their solid shot
in round numbers, including the 42-pnundcr ; larger pieces, rifle gvns, and mortars,
from the diameter of the bure.
DEFINITIONS.
Cateable. — The knob on the end of the breech of a gun ; it is composed of the
Arno6 and the ncc A'; sometimes the_^//ff.
Breech. — The mass of solid metal behind the bottom of the bore, extending to
the cascable.
lime of the hrrech. — The rear surface of the breech.
Base-line. — A line triwcd around the pun in rear of the rent.
Bate-riiKj. — A projecting liand of metal adjoining the base of the breech, and
connected with the body of the gun by a concave moulding.
Reinforce. — The thickest part of the body of thi- gun, in front of the base-ring
or lino: if there is more than one reinforce, that which if next to the base-ring i«
called the /ir«t reinforce ; the other, the second reinforce.
Reinforcc-hand. — A band at the junction of the fir-'t and second reinforces.
Chute. — The conical part of the gun in front of the reinforce.
Aitraijal and filletJi. — The moulding at the front end of the chase.
Chaic-riny. — A band at the front end of the chase.
Neck. — The smallest part of the piece, in front of the chase,
Sicell of the muzzle. — The largest part of the gun, in front of the neck.
Muzzle-hand. — A band which takes the place of the swell of the muzzle in some
guns.
Fact of the piece. — The plane terminating the gnn at the mnizle.
Trunnions. — Two cylinders, near the centre of gravity of the gun, by which it is
supported on its carriage. The axes of the trunnions are in a line perpendicular to
the axis of the bore, and, in our guns, in the same plane with that axis.
Rimhase. — The shoulder at the base of the trunnion.
Bore. — All the part bored out, including the chamber, and the junction of the
bore with the chamber.
Chamber. — The small part of some bores; it contains the charge of powder.
Gomer chamber. — A conical chamber which is joined to the cylinder of the bora
by a portion of a spherical surface.
True icindage. — The difference lietween the true diameters of the bore and of the
ball.
Lock-piece. — A block of metal at the outer opening of the vent, to facilitate
attaching a lock to the gun.
NOMENCLATURE. H
Kntural lin' of tight. — A line drawn in a vertical plane through the axis of the
piece, from the highest point of the bape-ring to the highect point of the swell of
the musszle, or to the top o'f the sight, if there be one.
NnturnI angle of sight. — The angle which the natural line of sight makes with the
axis of the piece.
Di^jiftrt.— The difference of the semidiameters of the base-ring and the swell of
the mnz/.le, or the muzzle-band. It is, therefore, the tangent of the natural angle of
sight, to a railius equal to the distance from the rear of the base-ring to the highest
point of the swell of the muzzle, the sight, or the front of the muzKle-band, as the
case may be.
Preponderance. — The excess of weight of the part in rear of the trunnions over
that in front: it is measured by the weight which the breech bears on a balance,
the point of support resting at the rear of the base-ring, at the base-line, or at
the bottom of the ratchet, the gun being suspended freely on the axis of the
trunnions.
HaniUet. — Flat rings cast on some bronze pieces: they are placed with their
centres over the centre of gravity of the piece.
Ear. — A lug of metal cast on some mortars: it is attached to a clevis by a bolt,
and constitutes a handle.
NOMENCLATURE.
Guns of the Model of 1861.
PartK. — The bore, a cylinder terminated by curved surfaces, the chamber. The
breech: the caacable, the knob, the neck. The body of the gnu: the reinforce, the
chase, the muzzle, the face, the trunnions, the rimbases.
3foiildings. — None.
CoLUMBiADS. — Add to the above the ratchet ; the sight-jyiece.
The vent is in the vertical plane of the axis, perpendicular to it, and enters the
bore at the termination of the cylinder of the bore, or in front of it.
Guns of the Model of 1841 and 1844.
The same as for guns of model of 1861, with the following exceptions:
Parts. — The bore is terminated by a plane perpendicular to the axis, united with
the sides (in profile) by an arc of a circle, the radius of which is one-fourth of the
diameter of the bore at the bottom. The vent is in the vertical plane passing
through the axis, and makes an angle of 80° with it. It enters the bore at a dis-
tance from the bottom equal to one-fourth the diameter of the bore.
Add the second reinforce, the swell of the muzzle.
Mouldings, — Add the filet of the cascable, the base-ring, the lock-piece, the chatte-
ring, the muzzle-mould tugs, ttvo echinus. The rimbases are cylindrical.
Field Guns. — The same as above, except as follcws: Omit the se-ond reinfone,
lock-piece, chase-ring, two echinus, and add vent-p>ifC€, wrought-coppur, screwed in,
for bronze guns. The astragal, the fillets, the lip, the fillet, the handles for ti.c
12-pounders.

MATERIALS FOR ORDNANCE. 17
MATERIALS FOR ORDNANCE.
Bronze.
Bronze for cannon (commonly called brass), consists of 90 parts of copper and
10 of tin, allowing a variation of one part of tin, more or less. It is more fusible
than copper, much less so than tin, more sonorous, harder, and less susceptible of
oxidation, and much less ductile tlian either of its components. When the mixture
is well made, the metal is homogeneous : the fracture is of a> uniform yellow color,
with an even grain. The specific gravity of bronze is about 8.700, being greater
than the mean of the specific gravities of copper and tin.
Pure cojtper is of a red color, inclining to yellow ; it has a fine metallic lustre.
The fracture of cast-copper is even grained ; that of a forged bar exhibits a short,
even, close grain, of a silky appearance; it is strong, very ductile ami very mal-
leable. The greater the purity of copper, the more malleable it is, and the finer
the grain. Specific gravity, from 8. COO to 9.000. The copper of commerce is
impure, freijucntly containing oxygen, silver, iron, lead, tin, zinc, antimony and
arsenic. It should be rejected, for the manufacture of guns, if it contain sulphur
in an appreciable (luantity ; more than one-thousandth of arsenic and antimony
united; more than about three-thousandths of lead, iron, or oxygen ; if it contain
more than about five-thousandths of foreign substances altogether; or if, near these
limits, it give bad results when subjected to the mechanical tests of hammering,
rolling and wire-drawinj^.
Pure tiv is of a white color, a little darker than silver: it is very malleable, and
susceptible of being rolled into thin sheets; it is not very ductile; it is soft, and
when in rods or bars is bent backward and forward, it gives a peculiar crackling
sound, the distinctness of which is in proportion to the purity of the tin. Specific
gravity, 7.290 to 7..320.
Tin, for gun-metal, should be rejected, if, when run into elongated drops, it have
not a smooth and reflecting surface, without any considerable sign of rough spots;
if, when analyzed, it contain more than about one-thousandth of arsenic and anti-
mony united; more than about three-thousandths of lead or iron; or more than
four-thousandths of foreign substances.
All bronze ought to be rejected which contains sulphur in an appreciable amount;
which contains more than about one-thous.andth of arsenic and antimony united ;
more than about three-thousandths of lead, iron or zinc; or, in all, more than
about five-thousandths of foreign substance^.
Notice should bo taken of the appearance of the fracture of specimens : it some-
times gives indications sufficient to authorize the rejection of certain bronzes full
of sulphur or oxides.
Analysis of Bronze.
Tin. — Nitric acid dissolves the copper, and converts the tin into an insoluble per-
oxide. Put into a small glass matrass 10 parts (say 100 grains) of bronze, in small
18 ORDNANCE MANUAL.
parlieleg, and 80 parts of very pure nitric a«id, at 22° Beaumo's hydrometer (spo-
cific gravity, 1.180); beat it gradually to cl>\il!itiou, and continue that heat »intil
red vaporB ceaso to come over. Let it settle ; jiour off the lif|uor, and add to the
oxide of tin 20 parts of nitric acid; let it boil ten minutes; decant the liquor
again, and repeat the same operation ; dilute the first portion decanted with 2 ui- 3
time? its volume of water, and pass it through a filter ; do the same with the second
and third portions. Then throw the oxide of tin on a double filter, tlie two parts
of which are equal ; wash the precipitate on the filter until the water that comea off
no longer gives a blue color when heated with ammonia, and due* nut change the
color of litmus paper. Sproad the filt .r on paper, and dry it perfectly in a stove or
a sand-bath. Weigh it, adding the exterior filter to the weights, in order to ascer-
tain the quantity of peroxide of tin which remains on the upper filter; 127 parts
of peroxide give 100 parts of pure tin.
CopPEn. — Collect the nitric acid solutions obtained in the process described
above: evaporate them to dryness; calcine and weigh the black rcsi<luum ; it is
the oxido of topper; 100 grains of oxide of copper contains 79.82 gr.<. of copper.
Or, dissolve in a large matrass with a narrow neck, about 1.1 gr. of bronze in pure
aqua regia, adding to it about 0.1 gr. of lead. Pour ii\to the solution an excess of
ammonia; then, keeping the liquid constantly boiling, pour into it from a gradu-
ated vessel a solution of monosulphuret of sodium, until the liquid becomes entirely
colorless. From the volume of sulphuret used, the amount of copjier in the liquid
can be determined.
SuLPHTR. — In boiling bronze in nitric acid or aqua regia, a jiart of the sulphur
is converted into sulphuric acid, whic'h remains in the solution : the rest collects on
the surface in yellow globules. These globules are collected and weighed.
The sulphuric acid is precipitated as a sulphate of baryta by the chloride of
barium, and is weighed after being washed and dried: 100 grains of the sulphate
of baryta contains 13.797 grs. of sulphur.
Mechanical Tests.
Chemical analysis is not sufficient to give a correct estimate of the qualities of
all bronzes. In other words, good bronzes according to the results of analysis may
be very inferior, deficient in strength, on account of oxides interspersed between
the molecules, or want of homogeneitjt
Bronzes should be subjected to fusion in a close crucible ; to hammering into
thin plates, and to wire-drawing, both before and after fusion ; if it improves in
these particulars by the fusion, a comparison with the analysis will show whether
the improvement is due to the volatilization of certain metals or to the decomposi-
tion of oxides. The results obtained by hammering and wire-draning, should be
compared with those made on bronze known to be- of tLe best quality.
MATERIALS FOR ORDNANCE. 19
Cast-iron.
(See also Chapter XIV.)
Iron for making cannon should be smelted with the greatest possible care, with
charcoal, and a blast of a constant temperature of 125° to 300°, depending upon
the ore used. All the materials which enter the smelting furnace should be of the
be.'rt and purest quality, should be kept drj', be supplied at regular intervals of
time, be regularly and uniformly mixed together in the sraelting-furnaee, and, as
far as practicable, rendered independent of the vicissitudes of the weatlier, that the
gi"catest possible uniformity in the iron produced from day to day may bo obtained.
The most important quality of gun-iron, after a medium strength of 25,000 to
30,000 pounds per square inch, is loiiformity, without which, no two guns can bt
made alike or any idea formed of what kind of guns are being made.
The quality of iron in the pig is generally judged of by its strength, and by the
appearance and feel of the freshly-fractured surface. It should be soft, j'ielding
easily to the file or chisel ; its fracture should present a rough, jagged surface, of
uniform appearance, a dark gray color, a brilliant aspect, and crystals under
medium size, angular, and sharp to the touch.
But iron for making guns requires to be still further tested before it can be
known, even by the most practiced eye and judgment, to possess all of the essential
qualities of a good gun-iron. These qualities are tenacity, elasticity, extensibility
and incompressibility : that iron will be the best which has them all to the greatest
degree, and the absence of any one will render the iron unfit for guns. The exist-
ence of these qualities is best determined by actual experiment on specimens cut
from castings of the size of the gun to be made.
The density is indicative, to some extent, of the tenacity, elasticity and incom-
pi-essibility of the iron ; but the density will increase after the tenacity and exten-
sibility have reached their maximum.
When cast into cannon, iron should be above medium in hardness, but yielding
readily to the file or chisel, and offering no groat difficulty in turning and boring.
Its color should be a bright, lively gray, showing incipient mottle in small guns,
and becoming more marked as the size of the gun, and time of cooling, increase.
The structure should be uniform, close and compact; crystals small, with acute
angles, and sharp to the touch; the fractured surface uneven, rough and jagged,
with many fragments strongly adhering.
Before making guns from an iron which has never been tried for this purpose, a
sample-gun of the calibre of the gun to be made should first endure a satisfactory
proof with service charges.
The mean specific gravity of gun-iron is about 7.248, and the average tenacity
about 30,000 per square inch.
20 ORDNANCE MANUAL.
Wroxight-iron and Steel.
Experimental guns have been made of wrought-iron and steel, giving satisfactory
results, and an order has been given for guns, to be made of the former material.
The superior strength of these materials, and the evenness, smoothness and hard-
ness of surface of which they arc susceptible, render it probable that these are the
materials of which our field rifle guns will soon be made, exclusively.
INSPECTION OF ORDNANCE.
Instruments.
1 &'l<ir-yau</e. — This is an instrument for measuring the diameter of the bore of a
gun, at any part.
The head is of brass, with four steel sockets for the measuring-points. Two of
the sockets are soldered fast into ^the head ; the other two are movable. The
uiMvable sockets and points are pushed out by moans of two inclined cylinders,
which are fastened to a stem, forming a conical slider. This slider tapers 0..35
inches in a length of 2.2 inches ; so that by pushing the slider the 35th part of this
length (about .06 inches), the distance between* the movable points is incrcai>od
.01 inches.
The slider is connected with a square steel rod, consisting of three parts, which
arc screwed together, according to the length of bore to be measured. This rod
slides through a brass tube, which is also made in three pieces.
The tube is graduated, m inches and quarters, commencing at the measuring-
points, so as to indicate the distance of the latter from the muzzle of the gun.
The handle is of wood, attached to a brass cylinder, or socket, through which the
sliding-rod passes. In the tube of the handle there is a slit, on the side of which a
scale is marked, to indicate the movements of the measuring-points. Each joint of
the long tube has a mark, made on a small plate of silver, which shows the place of
the zero on the scale when the measuring-points are adjusted to the true diameter
of the bore. In this position the handle is fixed on the sliding-rod by means of a
screw-clamp.
A riiig-i/aiige, for each calibre, is used for adjusting the instrument for use.
A >•(-»«, in the form of a T, is placed in the mouth of the gun, to keep the instru-
ment in the axis of the bore. This rest has three slides, which can be adjusted to
the diSFerent sizes of bore; the upright branch is movable, for convenience of
pa^^king.
The star-gauge, its points and rest, are packed in one box, and the ring-ganges in
another.
2. The cyJinder-stnff. — This is a round staflF, made of mahogany-, or other hard
wood. It is in two parts, which are joined together by brass sockets and screws;
each part has also a brass socket and screw at the outer end, to receive the cylinder-
gauge, guide-plate, and measuring-point. The staff is graduated, in inches and
tenths, on a strip of brass let into it, on one side. These graduations are arranged
INSPECTION OF ORDNANCE. 21
to read the distances from the extremity of the measuring-point, when it is screwed
on the staff.
The cylinder-staff is supported, at the muzzle of the piece, by a hulf tompion of
wood, having in the centre a groove of the size of the staff. The rent for the star-
gauge may be used also for this purpose.
3. The cylinder-yawje is a hollow cylinder of wrought or cast-iron, turned to the
exact minimum (or true) diameter of the bore. The length of the cylinder is equal
to its diameter. It has cross-heads, at right angles to each other: one with a smooth
hole of the same diameter as the cylinder-staff; the other tapped for the screw of
the staff-socket. Weight for 8 in., 27 lbs. ; for 10 in., 40 lbs.
4. The guide-plate is a circular iron plate 0.2 inch thick, and of the minimum
diameter of the bore; it has a hole in the centre, with a thread by which it is
screwed to the cylinder-staff j it serves to direct the measuring-point to the centre
of the bottom of the bore.
6. The nteaaurinij-pi)int is screwed on the end of the cylinder-staff, over the guide-
plate, to measure the depth of the bore : it is of iron, cylindrical in shape, so far
as it screws on the end of the staff, and tapering down to the diameter of 0.75 inch.
6. The trnnnion-iinnije is an iron ring of the diameter of the trunnions, which
must pass over them and fit closely. The exterior diameter of this gauge serves to
verify that of the rimbases.
7. The tnninioii-nqurtre is a double square of wood, the distance between whose
branches is the same as that between the rimbases of the gun; in the centre is a
pointed slidiug plate, with a thumb-screw to fasten it; the lower edges of the
branches, which are shod with iron, are in the same plane, parallel to the upper
edge of the connecting piece, so that when the square is placed with its l)ranches
resting on the truuuions. the upper edge of the connecting piece is parallel to their
axis. Each branch has also an iron plate projecting perpendicularly from one side to
rest on the top of the trunnions. It is used to ascertain the position of the trun-
nion^B in relation to the axis of the bore and to each other.
8. The trunnion-rule, for measuring the distance from the rear of the base-ring to
the rear of the trunnions.
9. Callipers, to measure diameters.
10. A standard scale, for verifying other instruments.
11. A wooden rule, to measure exterior lengths.
12. The vent-gauges are two pointed pieces of steel wire, 0.005 in. greater and less
than the true diameter of the vent.
\?>. The veiit-scarchcr is a hooked steel wire, about half the diamctur of tht
vent.
14. A rammer-head, shaped to the form of the bottom of the bore, and furnished
with a staff, is used to ascertain the interior position of the vent.
15. A mirror; siyerni candles ; beeswax.
16. Rammer, sponge, and priming-unre.
17. Figure and letter stumps, to affix the required marks.
22 ORDNANCE MANUAL.
Inspection of Ordnance.
Cannon proscntud for inspection and proof are placed on skills for the conve-
nience of turning and moving tlicni easily. They are first examined carefully on
tlio exterior, to ascertain whether there be any flaws or cracks in the metal, wlictlier
thoy be finished as prescribed, and to judge, as well as practicable, of thc()unlity of
the metal. They must not be covered with paint, lacker, or any other composition,
ir it be HHcertained that an attempt has been made to conceal any flaws or cavities
'j.V plugging, or filling them with cement or any substance, the gun is rejected with-
out further e.xamination. After this preliminary examination, the inspector pro-
coeds to verify the dimensions of the piece. The interior of the hare is first
examined by reflecting the sun's rays into it from the mirror; or, if the sun bo
obscured, by a lighted candle or a lamp placed on the end of a rod and inserted into
the bore. The cylinder-gntigc, screwed on the stafl", is then jtushed gently to the
bottom of the cylindrical part of the bore and withdrawn; it must go to the bottom,
or the bore is too small.
The hnre of the piece is then measured with the star-gauge. The measurements
should bo made at intervals of I inch in the part of the bore occupied by the shot;
at intervals of 1 inch in the rest of the bore in rear of the trunnions, and of about
1 calibre from the trunnions to the muzzle.
The position of the triitinioiig, with regard to the axis of the bore and to each
other, is next ascertained.
To verify the poeition of the axis of the trunnions. — Set the trunnion-square on the
trunnions, and see that the lower edges of its branches touch them throughout their
whole length ; push the slide down till it touches the surface of the piece, ami secure
it in that position bj- the thumb-screw: turn the gun over, and apply the trunnion-
square to the opposite side, and if, when the point of the slide touches the surface of
the piece, the lower edges of the branches rest on the trunnions, the axis of the
trunnions is in the same plane with the axis of the bore; if they do not touch the
trunnions, their axis is above the axis of the bore by half the space between ; and if
the edges touch the trunnions, and the point of the glide does not touch the surface
of the piece, their axis is below the axis of the bore. ' If the nlii/nment of the trun-
nions be accurate, the edges of the trunnion-square will fit on them when applied to
different parts of their surface: their diameter and cylindrical form, and the diam-
oier of the rimbases, are verified with the trunnion-gauge.
To ascertain the length of the bore. — Screw the gnide-plute and weaturimj-point on
the cylinder-staff, and push them to the bottom of the bore : jilace a half tompion in
the muzzle, and rest the staff in its groove; apply a straight-edge to the face of the
muzzle, and read the length of the bore on the staff. The exterior lengths are
measured by the rule, or by a profile, the accuracy of which is first verified. The
exterior diameters are measured with the callipers and graduated rule. The position
of the interior orifice of th^ rent is found from the mark made on the rammer-head
INSPECTION OF ORDNANCE. 23
by the veiit-gauf/e inserted in the vent, \7hile the rammer-head is held against the
bottom of the bore ; two impressions are taken. The position of the exterior orifice
of the vent is also verified. The rent is examined with gauges, and with the vent-
Hcarcher, to ascertain if there arc any cavities in it.
All bronze ordnance should be bored under size from .04 to .06 inch, and after
proof, reamed out to jthe exact calibre. Whitish ipntx show a separation of the tin
from the copper, and, if extensive, should condemn the piece. A great variation
from the true weight, which the dimensions do not account for, shows a defect
in the alloy.
In mortars, the dimensions of the chambers, and the form of the breech, may be
verified with patterns made of plate-iron.
After the powder proof, the bore is washed and wiped clean, and the bore and
vent are again examined, .and the bore remeasured. The results of each of the
measurements and examinations are noted on the inspection report against the
number of the gun.
A proper discretion must be exercised in the inspection of ordnance ; such slight
imperfections as do not injure a piece for service may be disregarded, whilst the
instructions should be strictly enforced with regard to defects which may impair
its utility.

PROOF OF ORDNANCE.
Gunpowder for proving ordnance should be of the best quality, giving not less
than the standard Initial velocity ; it should be proved immediately before being
used, unless it shall have been proved within one year previously, and there be no
reason to suspect that it has become deteriorated.
PROOF OF ORDNANCE — MARKS. 25
The caitridf/e-haija are made of cotton or paper, the full diameter of the bore or
chamber. They arc filled by weight; and, if not filled at the place where the
guns are proved, each bag should be enveloped in a paper cylinder and cap,
marked with the weight of powder and its proof qualities.
The shot must be smooth; free from seams and other inequalities that might
injure the bore of the piece, and they must be of Uie true diameter given in the
tables.
Guns and howitzers are laid with the muzzle resting on a block of wood, and the
breech on the ground, or on a thick plank, giving the bore a small elevation.
Jironze pieces are mounted on appropriate carriages or beds.
J/oit((r8 are mounted on strong wooden frames or iron beds, at an elevation of
45°, supported by the trunnions.
In proving iron ordnance, after pricking the cartridge, prime with powder, or a
tube, and place over the vent a piece of port-fire, set in clay or putty, long enough
to permit the man who fires it to reach a place of safety before the charge ex-

Should any of the guns proved at one time fail to sustain the above proof, the

The bore, vent, and the exterior surface of every piece which is approved should
be well covered with sperm oil immediately after the inspection.
MARKS.
All guns arc required to be weighed, and to bo marked as follows, viz: the num-
ber of the </nn, the initials 0/ the inspector's name and that of the foundry, the year of
fabrication, and the weiyht of the piece in pounds, on the face of the piece, in a

INJURIES CAUSED BY SERVICE.
Bronze guns are little subject to external injury, except from the bending of the
trunnions sometimes, after long service or heavy charges.
Internal injuries arc caused by the action of tho gases developed in the combus-
tion of the ptiwrlcr, or by tho action of tho shot in passing out of the bore. These
elTects generally increase with tho calibre of tho piece.
Of the first kind, the principal one is the cutting away of the metal of the upper
surface of the bore over the scat of the shot.
Those of the second kin<l arc : tkf lodijmmt »/ the ihoi, a compression of the
metal on the lower side of the bore, at the scat of the shot, caused by the prcsenre
of the gas in escaping over tho top of the shot. There is a corresponding burr in
front of the lodgment, and the motion thereby given to the shot cuuses it to strike
alternately on the top and bottom of the bore, pruducing other rulai-gvment*, gen-
erally three in number; it is chiefly from this cuui^) that bronze guns bocoLi^o unser-
viceable. Scratehcn caused by the fragments of a broken chot, or the roughness of
an imperfect one.
Tke durahiUty of bronze guns may be much increased by careful use, and by the
precautions of increanhig the length of the cirtri'dge, or that of the tabot, or using a
tcad over the cartridge, in order to change the place of the shot; by irrnjiping the
shot in trootleu or other cloth, or in paper, go as to diminish the windage and the
bounding of the shot in the bore. In lield g>in>, both bronze and iron, the paper
cap, which is taken off from the cartridge, should always be put over the shot.
Iron ijun» are subject "to tho above defects in a less degree than bronie, except the
corrosion of the metal. The principal cause of injury to iron guns is the rutting of
the metal, producing a roughness and enlargement of the bore.
The service to which an iron gun has been subjected may generally be deter-
mined by the appearance of the vent. After about 500 rounds the vent becomei
enlarged to .3 inch, and should not be longer used.
In rifled guns, the wear of the vent is about twice as great as in smooth-bored
guns.
Replacing vent*. — In bronze field pieces, the vent-piece is taken out and a new
one is screwed in. In other guns, the vent is filled up by pouring in melted rinc,
SPIKING AND UNSPIKTNG GUNS. 27
the vent being closed on the interior by means of clay placed on the head of a
rammer and pressed against the upper surface of the bore, and a now vent is bored
at a distance of two or three inches from the first.
Spilling and unspiking guns, and rendering them unserviceable.
To fpiJce u piece, or to render it unserviceable. — Drive into the vent a jagged and
hardened steel spiko with a soft point, or a nail without a head ; break it off flush
with the outer surface, and clinch the point inside by means of the rammer.
AVcdge a shot in the bottom of the bore by wrapping it with felt, or by means of
iron wedges, using the rammer or a bar of iron to drive them in ; a wooden wedge
would be easily burnt by means of a charcoal fire, lighted with the aid of a bel-
lows. Cause shells to burst in the bore of bronze guns, or fire broken shot from
them with high charges. Fill a piece with sand over the charge to burst it. Fire
a piece against another, muzzle to muzzle, or the muzzle of one to the chaSe of the
other. Light a firo under the chase of a bronze gun, and strike on it with a sledge
to bend it. Break off the trunnions of iron guns; or burst them by firing them
with heavy charges and full of shot, at a high elevation.
When guns are to be spiked temporarily, and are likely to be retaken, a spring
spike is used, having a shoulder to prevent its being too easily extracted.
7'o unspike a piece. — If the spike is not screwed in or clinched, and the bore is
not impeded, put in a charge of powder of J the weight of the shot, and ram junk
wads over it with a handspike, laying on the bottom of the bore a strip of wood,
with a groove on the under side containing a strand of quick-match by which fire
is communicated to the charge : in a bronze gun, take out some of the metal at the
upper orifice of the vent, and pour sulphuric acid into the groove for some hours
before firing. If this method, several times repeated, is not successful, unsci'ew
the vent-piece, if it be a bronze gun, and if an iron one, drill out the spike, or
drill a new vent.
To drive out a shot wedyed in the bore. — Unscrew the vent-piece, if there be one,
and drive in wedges so as to start the shot forward, then ram it back again in order
to seize the wedge with a hook; or pour in powder and fire it, after replacing the
vent-piece. In the last resort, bore a hole in the bottom of the breech, drive out
the shot, and stop the hole with a screw.
To use a piece which has been spiked. — Insert one end of a piece of quick-match
in the cartridge, allowing the other to project out of the muzzle of the gun. Apply
the fire to the quick-match, and get out of the way.
When quick-match of sufficient length is not at hand, insert one end in the cart-
ridge, the other projecting in front of the shot, and, after ramming the cartridge
home, throw two or three pinches of powder into the bore. Place another piece of
match in the muzzle, the end projecting out. The piece may bo fired in this way
without danger. Quick-match in the cartridge may be dispensed with by piercing
three or four holes in the cartridge-bag. In this manner the gun may be fired with
great rapidity.
28 ORDNANCK MANUAL.
PRESERVATION OF ORDNANCE.
Cannon Fhould be placed together, according to kind and caliliro, on skids of
stone, ircjn or wood, laid on hard ground, well rammed, and covered with a layer of
cinders or of some other material to prevent vegetation.
Guim and bnnj howitzers. — The pieces should rest on the gki<l.« in front of the base-
ring and in rear of the astragal; the axis inclined at an angle of 4 or b degrees
with the horizon, the muzzle lowest; the trunnions touching each other; or, if
space be wanting for that arrangement, the trunnion of one piece maj rest on the
adjoining piece, so that the axis of the trunnions is inclined about 45° with a hori-
zontal lino; the muzzle closed with a tompion or a plug of dry wood, well saturated
with oil or grease ; the vent down, stopped with a greased wooden plug, or with
]>utty or tallow. If circumstances require it, the pieces may be piled iu two tiers,
with skidding placed between them, exactly over those which rest on the ground;
the muzzles of both tiers in the same direction and their axes preserving the same
inclination.
i)/ii>ri howiJzcra and moriarn. — On thick planks, standing on their muzzles, the
trunnions touching, the vcuts stopped.
Iron ordnance should be covered on the exterior with a hickcr impervious to
water (see Chap. VII); the bore and the vent should be greased with a mixture of
oil and talluir, or of tiillotc and beemnix melted togclher, and boiled to expel the
water. The lacker should be renewed as often as required, and the grease at least
once every year.
The lacker and grease should be applied iu hot weather.
The cannon should be frequently inspected, to see that moisture dues out collect
in the bore.

SHOT AND SHELLS.
NOMENCLATURE. DIMENSIONS, WEIGHTS.
Shot, shells, grape and canister shot, take the name of the gnn or howitzer in which
they are used. The size of grape and canister shot is so regulated that a certain
number shall chamber in the bore.
The ears of a shell are holes for the points of the shell-hooks, 0.5 inch in diame-
ter, bored on opposite sides of the fuze-hole, their axes perpendicular to the axis of
the fuze-hole. The metal is cut out above them at the distance indicated in the
table, in a direction perpendicular to the axes of the holes, which must remain
0.25 inch deep, with a thickness of 0.25 inch of metal above them, at the thinnest
part.

General directions in the fabrication of shot and shells.
All shot and shells, except canifiter shot for mountain howitiers, are made of
cast-iron. It should be gray or mottled iron, of good quality. (PeoChap. XIV.
Catt-iroH.) They must be cast in sand, and not in iron moulds : the shot from the
latter are generally not spherical in form, nor uniform in sue : they are also full of
cavities, and arc cracked by being heated.
Sp)iericnl-cn»e "hot must be made with peculiar care, of the best quality of iron,
in order that they may not be liable U> break in the gun.
Grnpe and eaninier »hui should be made of a soft. ;:ray iron : it ought to be vary
fluid. They are smooth, and polished by rolling in a barrel for that purj.ose.
A sample bar, 1.5 inch square and S inches long, with a head 4 inches long, is
cast, on end, from the same meul th.it sh<a and shells are made of, to be tested as
to its strength and the character of the metal.
i
INSPECTION OF SHOT AND SHELLS. 33
INSPECTION OF SHOT AND SHELLS.
Shot.
Inspecting Instruments. — One large and one small gauge, and one cylinder-
gauge, for each calibre : the cylinder-gauge has the same diameter as the large
gauge ; it is made of cast-iron, and is 5 calibres long. The gauges should be veri-
fied from time to time, and when they have become .008 larger than their true
diameter, they should no longer be used. One Aammer, weighing half a pound, and
having a flat face and a conical point. Steel punches.
One searcher, of steel wire, No. 20, with a handle.
The shot should be inspected before they become rusty ; after being well cleaned,
each shot is placed on a table and examined by the eye to see that its surface is
smooth, that the metal is sound and free from seams, flaws, and blisters. If cavi-
ties or small holes appear on the surface, strike the point of the hammer or punch
into them, and ascertain their depth witli the searcher; if the depth of the cavity
exceed 0.2 inch, the shot is rejected ; and also if it appear that an attempt has been
made to conceal such defects by filling up the holes with nails, cement, etc.
The shot must pass in everj' direction through the large guage, and not at all
through the small one ; the founder should endeavor to bring the shot up as near
as po.ssible to the large gauge or to the true diameter.
After having been thus examined, the shot are passed through the ci/linder-gauge,
which is placed at an inclination of about 2 inches between the two ends, and sup-
ported on blocks of wood in such a manner as to be easily turned, from time to
time, to prevent its being worn in furrows. Shot which slide or stick in the cylin-
der are rejected : the latter must be pushed out from the lower end with a wooden
rammer.
Shi)t are proved by dropping them, from a height of 20 feet, on a block of iron, or
rolling them down an inclined plane of that height, against another shot at the
bottom of the plane.
The average weight of the shot is deduced from that of three parcels of 20 to 50
each, taken indiscriminately from the pile : some of those which appear to be the
smallest should be also weighed, and they are rejected if they fall short of the
weight expressed by their calibre more than one thirty-second part. They almost
invariably exceed that weight.
Grape and Canister Shot.
The dimensions are verified by means of a large and a small gauge attached to
the same handle. The surface of the shot should be smooth, and free from seams.
Shells and Hollow Shot.
Inspecting Instruments. — A large and small gauge for each calibre, and a
cylinder-gauge for shells of 8 inches and under.
Callipers for measuring the thickness of the metal at the sides of the shell.

The furfHoe of the fhell and it8 exterior dimeii!ioni< are examined as in the case
of f<hot, particuiar attention bein;; ]>uid to tin' hemisphere rippfiiiiie the fuxe-hole.
CavilieH and imjierfeelionei in casting are generally fouml about '.U\° from the top of
the dholl, when in the position in which it waj cast. KhelU lihould l>c rejected for
rough casting, projecting seami!, sand-flaws, a collection of dross, cavities or honey-
combs of more than two-tenths of an inch in depth, whatever their diameter, or a
number of small holes giving the projectile a apongy appearance.
The shell is next struck with the hummer, t4i judge by the hound whether it be
free from cracks; the position and dimensioni of the cars arc verified : the thick-
ness of metal is then measured at several points on the great circle iterpcndicular to
the axis of the fur.e-hole, and at the bottom, and at the fute-hole. The diameter of
the fnnc-holc, which shouUI be accurately reumed. is then verified, and the sound-
ness of the metal about the inside of the hole is ascertained by inserting the
finger.
The shell is iinw ]daced on a trivet, in a tub containing water deep enough to
cover it nearly to the fute-hole: the bellows and plug are inserted into the fucc-hole
and the air forced into the shell ; if there be any holes in the shell, the air will rise
in bubbles through the water. This test also gives another indication of the sound-
ness of the metal, as the parlK containing cavities will dry more slowly thas^fc*
other parts.
The mean weight of shells is ascertained in the same manner as that of sliot.
Shot and shells rejected in the inspection are marked with an X, made with the
cold-chisel : on shut near the gate, and on shells near the futc-hole.
PRESERVATION AND PILING OF BALLS.
Balls should be carefully lackered as soon as possible after th«y ure received.
The ncir 8-iiirA eiilid '■hot are painted red, to distinguish them from the old, which
will not answer for hot-shot firing. All tpkerieal-aitr »hot are also painted red.
Other projectiles arc lackered hl<uk. For the composition of lacker and the manner
of apjilying it^ see Chap. VII.
When it becomes necessary to renew the lacker, the old lacker should be remored
by rolling or scraping the balls, which should never be heated for that purpose.
Balls are piled according to kind and calibre, under cover if practicable, in a
place where there is a free circulation of air. to facilitate which, the pile' should be
made narrow if the locality permits; the width of the bottom tier may be from 12
to 14 balls, according to the calibre.
PTLING OF RALLS. 35
Prepare the grour-l '■ r the base of the pile by raising it above the surrounding
ground so as* to throw oil' the water ; level it, ram it well, and cover it with a layer '
of screened sand. Make the bottom of the pile with a tier of unserviceable balls,
buried about two-thirds of their diameter in the sand; this base may be made per-
manent: clean the base well and form the pile, putting the fuze-holes of shells
downward, in the intervals, and not resting on the shells below. Each pile is
marked with the number of serviceable balls it contains.
The base may be made of bricks, concrete, stone, or with borders and braces of
iron. Good and imperfect b.alls should not be used in the same base : and, to avoid
confusion, the unserviceable should be left unpainted, or painted of a different
color from the serviceable.
Grape and canister shot should be oiled or lackered, put in piles or in strong
boxes, on the ground-floor or in dry cellars, each parcel marked with its kind,
calibre and number.
To find the number of balls in a pile.
Multiply the sum of thv three parallel edges hy one-third of the number of halls in a
triangular face.
In a square pile, one of the parallel edges contains but one ball ; in a triangular
pile, two of the edges have but one ball in each.
The number of balls in a triangular face is ^-~~^; n being the number in the
bottom row.
The sum of the three parallel edges in a triangular pile is n -f-2; in a square
pile, 2 »( -f 1 : in an oblong pile, 3 TV-f 2 n — 2 ; iV being the length of the top row,
and n the width of the bottom tier: or, 3 »i — h + 1 ; m being the length and n the
width of the bottom tier.
If a pile consist of two piles joined at a right angle, calculate the contents of one
as a common oblong pile and of the other as a pile of which the three parallel
edges are equal.
To find the length of a jnle ivhich shall hold a given number of
balls, the width of the base being fixed.

Each carriage is composed of a chassis and top carriage.
The inclination of the chassis-rails is the same in all the carriages — 3°. The
trough-beam braces, transoms and angle-iron sub-braces vary only in length, the
flank-casemate carriage excepted. The thickness of the cheek-plates is the same in
all. The barbette rails diflor both in length and depth from the casemate, which arc
also diflferent from the flank-casemate.
BARBETTE CARRIAGES.

ARTILLERY IMPLEMENTS AND EQUIPMENTS. 121
Chapter Fifth
AETILLERY IMPLEMENTS AND EQUIPMENTS.
NOMENCLATURE, DIMENSIONS, WEIGHTS.
Rammer-Heads.
Rammkr-heads are made of ash, maple, birch, beech, elm, gnm, or other tough
woods ; the head is bored S of its length with a hole 0.25 inch less than the diame-
ter of the staff, which enters with a tenon. The staff is driven into the head and
fastened with a, pin of hard wood 0.3 inch diameter: the neck has a copper band 0.5
inch wide and 0.05 inch thick, fastened with 3 copper nails. For dimensions, see
page 132.
Sponge-Heads.
Sponge-heads are made of elm or poplar, etc. The head is bored 5 of its length
with a hole 0.25 inch less than the body of the staff, which is inserted in a tenon and
fastened by 2 hard wood pinit 0.3 inch diameter.
Rammer, ladle, and sponge-heads should be saturated, when new, with linseed oil,
to prevent splitting from alternate wetting and drying in service.
For the woven woollen sponge the diameter of the head is 1 inch less than the
calibre of the piece.
Sponges.
Sponges are made of coarse, well-twisted woollen yarn, woven into a warp of
strong hemp or flax thread, after the manner of Brussels carpet; the loops are 0.75
iuch long.
They are woven in webs with selvages between them, which being cut, the
sponges are sewed to fit formers of the same dimensions as the sponge-heads. One
end of the sponge is drawn together with strong twine, and a tuft of woollen yarn is
inserted at the centre of the gather or folds; a circular piece of strong canvas is
stitched inside of the bottom; the other end, after receiving the sponge-head, is
nailed to it around the staff with 6 copijer nails, 1 inch long; 3 copper nails should
also be driven into the bottom of the sponge, to secure it to the head.
122 ORDNANCE MANUAL.
Similar sponges are made by working the yarn with needles into canvas bags ;
but the wove sponges are equally good, and less expensive.
Sponges are likewise made of sheep-skin alum-dressed, with the wool on ; but
they arc inferior to those made of yarn.
For dimensions of sponges, see Table of spouge-heads, page 132.
Sponge- Covers.
They are made of Russia duck.
The interior diameter is equal to the calibre of the piece. A hem 0.5 inch wide
around the top, receives a cord 0.2 inch diameter, by which the mouth is drawn
together and tied aroun<l the sponge-staff: a loop of canvas 0.75 inch wide is sewed
on the end of the cover, to draw it off by.
The covers are marked in black with the calibre of the gun.
Ladle- Heads.
Ladle-heads are made of the same kinds of wood, and arc fastened to the staves
in the same manner as rammer-heads.
Ladles.
Ladles are used for siege, garrison, and sea-coast guns only. They are made of
sheet-copper No. 18.
Toward the mouth of the ladle, the copper is spread a little, so as to increase the
diameter of the ladl* 0.,3 inch : the corners are rounded with a radius of from '2
inches to 3.5 inches. To stiffen the ladle, the copper is planinhed after being bent
and brazed. The ladle is attached to the head by 6 to 10 copper nuiU, 1 inch long,
driven in two rows around the l^ody, about 1 inch apart.
Worms.
There are two sizes of worms, one for siege or garrison guns, and the other for
field guns. They are fastened to their staff by 2 iron riiets, .25 inch in diameter.
Staves.
Staves for implements are made of tough ash.
The diameter of the tenon is 0.25 inch less than that of the staff; its length, 5 of
that of the head into which it is inserted. For worms it is pointed to fit the conical
form of the socket.
For field guns, field, siege and mountain howitzers, and mortars, the rammer
and sponge heads are on the same staff; for other pieces, on separate staves.
For the Coehorn mortar, the body of the staff forms the rammer and sponge-head.
For lengths of staves, see page 132.
For other cannon than those of the patterns described in Chapter I, staves may
IMPLEJ4ENTS AND EQUIPMENTS. 123
be made of such a length that the finished implement shall bo 18 inches longer than

ARTILLERY HARNESS AND CAVALRY EQUIPMENTS.*
ARTILLERY IIARXKSS. (Plate 21.)
The poni'truption of tho field carrisfteii re(|uiroB u harnoii(i difforpnt, in jnine
roKpeftfi, frmn liiat <»f ronimoii wa;r<>iii). The liiDlier havint; no Hwecp-har, the pole
ill «up|)orte(l directly hy the wherl-horseii, liy nic&ni< of a chain which connectj) the
haineK with the pole-yoke of the limber; and, in order to diminish the weight at the
end of tho pole, the leadrn;;-bnrr are dispensed with, the truceii of tho leaders being
attached to those of the wlieel-horscs.
The Fame harnes!< ii" perfectly adapted also to the ^icgc carriages; hut, aa theae
arc arranpol for driMi;;ht in the ordinary manner, eouuion wugou harness may be
used with them if necesfiary.
Leather.
Leather i^ generally <lirided into two kinds: let, that which is tanned an<l under-
gftpg no further ]ircparation : and. 2d. that which io tanned and is afterward curried-
The former iudiides all made from the heavier skins of the larger animuU. m buf-
faloes, oxen, and cows, into thick, strong §i>le-lr<tlher, and the latter that made from
the thinner skins of horfcf. cows, calres, sheep, etc.. into liuriift, bri(iU,up/>rr,h4tg,
or punch leather, which differ fr..in each other only in thickncsc, the first being the
thickest. There arc other kinds besides these, designated from the mode of prepa-
ration, as ffur»(/ leather, such aa white kid or sheep-skin, prepared with alum and
salt: huck-nklH and bujT leather, so called from the fact that the buffalo and deer-
skins were first most commonly dressed in this way: pntent Uather, that which bM
been varnished. It is sometimes distinguished by its color, as Hack.fnir. or rtutet
le.ither. Leather which ha,« been a long time in tanning is to be preferred to that
wbich has been produced more rapidly. The quality is judged of by its appear-
ance : a cross-section should be glistening and marbled, without any white streak*
in the middle. It should be firm, compact, and pliant.
The actual strength of leather depends more on its quality than on its thickneas.
That made from bulls' hides should be rejected: it is thick and supple, but. like
• TUU style of barncM will be conformed to aa toon as pro|ier Mddle-treec cao be obtained.
,«|* HEAD-OEAR. 13T
that made from the legs and flanks of other skins, it is spongy, without strength or
endurance, and, if only slightly rumpled, the hair side presents a shrivelled appear-
ance, which it retains.
The different parts of harness, except straps and the like, are cut out by means
of patterns. The seams arc made with strong waxed thread, in double stitch, with
about eight stitches to the inch : those along an edge are from 0.1.''i to 0.2 inch from
the edge. The ends of the threail should be securely fastened before they are cut
off. The awl used should be small for the thread.
Buckles, Loops, etc.
The buckles of the bridle and stirrup leather, and the loops for the cloak and
valise-straps on the driver's and valise-saddles, arc cast-brass, with rollers; and
the book and loop on the pommel of the valise-saddle is brass-plated. They are
designated by numbers. (See table, page 157j. All other buckles, loops, and
staples are of wrought-iron, japanned (black). The iron buckles are all made with
rollers; the tongues are the same size as the sides of the buckles.
Straps, or other pieces which have buckles or iron loops attached to them, aro
doubled on a length generally equal to twice their width, to receive the buckle or
loop, which is fastened by two seams. The double end is shaved down.
Standing-loops are placed close to the buckles. Their ends arc shaved down,
brought together, and fastened between the two parts of the strap, if it is doubled,
by the same seam. These loops arc usually of the same leather as the strap.
The tongue-holes for buckles are made with a punch corresponding to the size of
the tongue. Their distance apart is generally equal to the width of the strap, and
the first hole is at double that distance from the end of the strap. This end is
shaved down and reduced in width, to facilitate its entrance into the buckle.
Note. — A laucr is a piece of leather sewed upon another piece, to strengthen it.
A chiijie is a piece used to fasten a buckle or loop to a strap or other piece of
leather.
A billet is a strap which enters a buckle.
A «rt/c is a piece of leather placed under a buckle, etc., to prevent it from chafing.
Composition. — A complete set of artillery harness is composed as follows:
Head-gear. Driver's saddles, the same for all the near horses. Valise-saddles
and valise, common for all the off horses. Draitf/hl harness, differing according as
it is intended for the wheel or lead-horses. One ivhij) is allowed to each driver, and
one leg-guard to each driver of wheel-horses.
Head-Gear.
The head-gear is made of strong, black bridle leather, not less than 0.1 inch thick.
The buckles of the bridle are brass-plated or cast-brass ; of the halter, iron.
Bkidle of the near house. — It is composed of the headstall, hit and pair of
reins.

Inspection of Harness and Horse Equipments.
The inspection is made before the parts arc assembled. For the conrenicnce of
the inspector, the diflTorenl parts are arranged in 8e]>arate piles.
Materials. — The quality of the materials is first examined.
The leather should he firm, elaitic and plinhlr, and should be smcoth and shaved
to a firm surface on the flesh side. If it feel hard and horny to the hand, or, being
bent, it cracks in the grain, or, when cut, it exhibits a hard an<l i-hining texture, it
is an indication that the leather ha« not been tanned sufficiently, and it should ^le
rejected. Leather which bos been tanned with hemlock should not be received.
The traces, the breast-straj) and pole-strap, and straps generally, should be made of
tho strongest leather, and the saddle-skirls of the thi<'kest leather.
The nialltahlf iron parts should be tested by taking some jiieees and bending them
back and. forth to see that they have the requisite toughness.
WoiiKMANsnii'. — Tho saddle-trees should be inspected before they are covered,
that it may be seen that the proper kind and quality of wood has been used, that
the framing of the parts is well done and secured, that the surface ie smooth, the
angels rounUcd, and that the irons arc properly fastened.
No old or brash wood should be used.
Examine tho edges of the different parU of leather, that they are well blacked
and rubbed smooth ; that the seams are at the proper distances from the edges,
according to the width of the parts: that the splices and laps are. of the proper
length: that the stitching is neatly done with a uniform length of stitch : that the
thread is well waied, and the ends, whenever they occur, secured with a double
knot.
Examine the collars, that they are stuffed compactly. Especial care is to be
taken to see that no lumps or irregularities occur on tne belly, or part which comes
against the shoulders of the horse.
See that the billets pass freely through the loops, that the holes are punched at
the proper distance from each other in the central line of the billet, and that they
just admit the tongue of the buckle with ease and no more.
IIORSESUOES AND NAILS. 153
Observe the rollers of such buckles as have them, that they work freely, and are
sufficiently stiff not to be flattened.
See that the seams of the raw hide covering the tree are well made and will not
chafe the horse or rider; that the skirts arc thinned down where they are fastened
to the trees, the screw-heads are well sunk, and there is as little unevenness at this
place as possible : that the stirrups are well riveted at top, and the wood is not split
by the rivet.
Examine the bits, that tbey are ma<le of the proper materials: that the mouth-
pieces are forged solid ; that they and the cross-bars are firmly fitted to the chcek-
j)ieces; that the curb-rings work freely and are properlj' shouldered to keep them
in place; that the watering-bits are free from cracks or ilaws at the joint of the
mouth-piece.
Sec that the blueing is, in all cases, of a uniform dark blue color, free from any
yeHow tinge.
The general characteristics of all the work should be neatness and strength.
All the parts are fiuallj' measured and verified, to see that they conform in shape
and dimensions to the established patterns.
Preservation of Harness in Store.
The storehouses should be well ventilated, not too dry, but free from dampness.
The different articles should be arranged according to kind and class, separated or
in bundles according to their nature, so placed as to touch each other and the walls
as little as possible, having a free circulation of air about them : — saddles on trestles
or bars — collars hung on pins — hames witb'their straps, and traces with chains and
hooks, hung up; the traces hanging vertically — side pipes and lielly-hands piled on
the floor or on shelves — surcingles and brenst-strapa stretched on racks — halters,
bridleSf reins, etc., hung up in bundles of five or ten — hames-sfraps, collar-strains, etc.,
hung up in bundles of ten or twenty — bits, curb-chains, trace-hooks, in boxes.
All these articles should be examined and cleaned at least fpur times a year.
The leather articles are brushed and greased with neat's-foot oil, as often as their
condition requires : if they have a reddish hue, mix a little lampblack with the oil.
First brush the leather carefully, then pass over it a sponge wet with lukewarm
water; grease it slightly on the hair-side, applying the oil with a soft brush before
the leather is quite dry. In general, new leather is not greased until it has been
in store three years, unless it should be found to require it. Iron parts which are
not japanned or tinned, or from which the coating is rubbed off, are greased with
tallow.
Horseshoes and Nails.
The principal parts of the shoes are the two fuces ; the two edges, the inner and
outer; the toe, the front part; the quarters uniting the too with the heels — the ful-
lering, the crease in which the nail-holes are made: there are generally eight holes;
the calls, projections at the extremities of the heels on the lower face: they serve

principally to prevent the horse from slipping: they ghonid be used with osntion ;
the rlip, A kind of olaw on the outer C(l>;o of the shoe, gt-ncrnlly on the toe of the
hind fool, HometinieK on the outer quarter, in which case a pmiill one is made on the
inner one: they are used to keep the shoo in place and to guard the hoof; thr bevrl,
the concavity of the upi)er face, that the iron may in no case rest on the arch of the
sole of the foot.
The hind shoes are generally a liitle thicker and broader at the toe than the front
shoes. The front shoes are punchcil nearer the toe, the hind shoes nearer, the
heels.
The principal parts of the nail arc the hcod, the body, and the poini. The heaik

General Directions for Shoeing Horses.
The shoe should be forged to fit the form of the foot: it should project on the
outside at the end of the heel about its thickness, beginning at the lart bole; should
be flush with the hoof at the toe and on the inside; the heels generally short and
thin. The holes in the outer quarter should be farther from the edge, and in the
inner quarter nearer the edge; in the front shoe nearer the toe, and in the hind
shoe nearer the heel. Make the lower face of the shoe perfectly flat, and try it on
an iron table. The shoe should bear equally all around on the wall of the foot, and
not at all on the sole.
A judicious preparation of the foot for the shoe is 01 the greatest importance,
strict attention being paid to its peculiarities.
Cut away the wall no mure than is necessary to make the eh<je fit; pare the sol*
and the frog ^ery sparingly; in using the buttress, place it flat on the fuot, and cut
oflT the hoof evenly. The whole thickness of the wall should be left perfectly flat
SHOEING HORSES. 155
or the bearing of the shoe, which should never rest on the sole. The bars should
nevQr be pared except in cases of contracted feet, and then with judgment.
Do not apply the shoe to the foot when too warm; keep it there but for a short
time. Drive the nails in the sound hoof and rivet them solidly, all at the same
height.
In rasping the rivets, do not touch the wall of the foot : it weakens the foot.
When a nail binds, draw it out and take another. If the horse suddenly jerks his
foot after a blow of the hammer, withdraw the nail immediately.
Shoes .should not be allowed to remain on more than five weeks, when they should
be removed, the useless hoof pared off and the shoe replaced if it be still good.
This should be regulated by the length of the hoof rather than by the wear of the
shoe. In removing shoes, take caro to raise the clenches first, that the crust may
not be torn or portions of the nail left in the hoof. It is better to remove the shoes
one at a time as the new shoe is ready to be put on.
Rough shoeing differs from ordinary shoeing only in the form of the nails, the
heads being longer and more pointed.
The shoe used in all other services is to be preferred to that in use in ours. It
has no fullering, but each hole is countersunk to receive the head of the nail, which
is less apt to be broken off, as it is well supported on all sides : the shoe is not
weakened by fullering.

ing over a slow charcoal fire, for fiva hours, all the ingredients, except the turpen-
tine and a small purlinn of the oil; the latter is added ax rc<|iiired, to check the
ebullition and allay the froth which rises to the surface. It must bo continually
•tirred with a wooden spatula, and great cure is necessary to prevent it from taking
fire.
The turpentine is added after the varnish is nearly cool, and it is litirrcd well in.

The pyrolignate of iron is made by dissolving iron filings in pyroligneoas acid —
as much as the acid will take up.
The addition of the logwood is not essential.
A solution of copperas may replace the pyrolignate of iron, but it is not so good.

1 pair of rollt for welding and shaping the barrel. They have 9 grooves, of dif-
ferent sizes. 2 of them parallel and 7 taper : it has an iron frame to hold the end of
the mandrel. The rolls make 36 revolutions per minute.

1 straightening table, iron. 1 straightening machine, with 2 dies the length and

makes 60 revolutions per minute.
2 trip-hammers, with dies.
To form the cylinder. — The plates are put into the furnace and raised to a white
heat, and then passed through the rolls, each groove in succession. The first groove
forms the plate into a trough shape ; the second and third grooves contract it gra-
dually : the fourth turns the two edges inward, and the fifth completes the cylinder.
The operation is performed at one heat.
A day's work. — 3 men can form 450 cylinders in 10 hours.
To weld and shape the barrel. — The fireman places two cylinders in the furnace,
and brings them to a welding heat; the foreman thrusts the largest mandrel
through one of them while yet in the furnace, and, taking it to the rolls, puts the
mandrel through the frame, introduces the end into the first groove, and the cylinder
is drawn over the bulb of the mandrel, which is held by the collar.
The first assistant, standing on the opposite side of the rolls, catches the barrel
as it passes through, with a pair of tongs, and hands it to the second assistant, who
stands on the same side as the foreman, and receives it with a small, short mandrel,
which he thrusts into the barrel, and straightens it by striking it twp or three times
on the flat table. lie then replaces it in the furnace, and it is raised to a welding
heata second time. The foreman takes out the other cylinder, and proceeds with
it in the manner just described. When the barrel is brought to a welding beat the
second time, the foreman takes it with the next smaller mandrel and passes it
through the second groove, b}" which the barrel is reduced in diameter and length-
ened : it is straightened as before, and returned to the furnace.
The third and remaining grooves taper so as to give the barrel the shape of a
frustum of a cone, each succeeding groove reducing the size of the barrel and mak-
ing it longer. The rolls are of such size that a single revolution takes the barrel
through ; as they continue to revolve without stopping, it requires caro and dex-
terity on the part of the foreman to insert the barrel in the groove at the proper
time, bringing the end against the shoulder in the large part of the groove.
The barrel is so much chilled by passing over the mandrel, that it is necessary it
should be straightened and reheated before passing it through the next groove : a
high red heat is required.
After the barrel has been passed through the first eight grooves with their corres-
ponding mandrels, it is taken with tongs and passed twice through the last groove,
for the purpose of making it round and smooth.
To straighten the barrel. — The foreman inserts the muzzle end of the barrel in the
dies and turns it around gradually, when the dies are open, pushing it farther into
the dies until its whole length is embraced by them. The barrel then receives the
pressure of the dies from ten to fifteen times, when it will bo found to be straight.

INSPECTION OF S.MALL ARMS.
All the materials used in the manufacture of arra< must be of the best quality,
and they should be tested by the inspectors, according to the methods indicated in
Chapter XIV.
The wood for gun-stocks should be seasoned at lea=t three years, and kept in a
dry place two years before being worked ; it mui^t be free from knrts and sap, and
no woiid which is brash, or light, or wnrm-eaten. or in any degree decayed, or which
is cut across the grain at the handle of the stock. '>r which is kiln-dried, should b«
used or received.
INSPECTION OF BARRELS.
175
The following rules for inspection apply to all small arms,, whether made at the
national armories, or by contract at private establishments.
The attention of the inspecting officers should be directed as much as possible to
the o])erations of the workmen in the course of the fabrication of arms.
Each component part is first inspected by itself, and afterward the arm in a
tinishcd state.
The materials and the forms and dimensions of all the parts must conform strictly
to those of the established patterns; the workmanship and finish must be equal to
those of the model arms, and the several parts must be browned, l)lued, ease-hard-
ened, or polished as in the standard model.
The forms and dimensions of the parts are verified by means of the standard
gauges. (See p. .)
Inspectioti of Barrels. »
The Jii-Kt inspection of the barrel is made in the forged or cone-seated stage; the
second in the 3d bored stage ; the third in the <jround stage ; thd fourth in the proved
stage; the fi/lh in the fled stage; the si'jrth in the 6th bored stage; the acicnth iu the
rifed stage ; and the eir/hth in the breeched stage.
In these inspections, the inspector will vcrifj' the barrel with proper gauges for
each stage; he will see that the thread for the breech-screw in the barrel is well cut,
and the bayonet-stud firmly brazed on ; that the exterior and interior dimensions of
the barrel arc correct; that there are no interior hammer-marks, ring-bores, cinder-
holes, flaws, cracks, or other defects which will not disappear in the finishing; and
that the thread of the breech-screw is accurately cut.
The barrels rejected for defects that cannot be remedied will be stamped on the
upper side, in a line with the vent, with the mark of condemnation, which will be
in all cases the letter €. If the defect is of such a nature as not to prevent the use
of the barrel for a shorter arm when cut off, the mark will be made on the defective
part.
Proof. — The barrels which pass this inspection will then be proved by being fired
twice, with the following charges :

One wad is placed oo the powder and the other on the ball, and the charj^e is well
rammed with a copper rod. The wad occupies, when rammed, altout J inch in the
length of the barrel.
The barrels arc closed for proof with proving -phir/n having vents in them.
Musket powder will be used for proving the barrelfi of muskets ; tho powder must
be of the bcft i|Uftlit\-, giving not less than the standard initial velocity: it must
Iw proved inimediutoly before being used, unless it shall have been proved within
one year, and the inspector has no reason to suppose that it has become deterior-
ated.
The measures for the proof-charges should bo of a conical form, with tho mouth
aa Biuall as may bo convenient, in order that there may be less variation in the
quantity of powder.
Before commencing the proof of barrels, tho inspector will satisfy himself as to
tho quality and proof of the powder, the siie of the balls and of the wads.
The inspector will observe the greatest caution in having the bnrreli properly
loaded; for which purpose, after they arc placed on the proving-bcd, he will i)ass a
ramrod into each barrel, to verify the accuracy of the charge.
After the discharge he will again pass tho ramrod into each barrel, and those
which have missed fire will be pricked and primed and discharged, before proceed-
ing to tho second proof-charge.
After the second proof-charge, the inspector will examine the barrels which have
burst, and note the cause of defect, whether in the materials or workmanship.
He will then examine those which have not burst, and lie will mark, as cod-
dcmned. any which are evidently <lefective; tho others will rcciivc the proof-stamp.
Til: V for viewed, P for proved, with the eagle's head under them, placed on the
loft square of the barrel, opposite the cono-seat. The barrels will be immediately
washed clean, in hot water, and dried, after which they will be again carefully
examined.
They will now be insjiected in the interior and on the exterior; the inspector
will reject such as arc ton large in the bore, and such a« have holes, cross-cracks,
scales, seams, or ring-bores; he will examine the braiing of the bayonet-stud, and
see that the barrel is not mitched too deep, or indented inside.
The barrels, having been reduce<i to their ultimate dimensions, straightened, and
oomplelely finished, are again strictly inspected, to verify the straightnesi of the
bore, the exterior and interior diameters, their weight (which should not Tary
more than 1 ounce from the standard weight), the taps for the breech-screw and
cone, the sire, position, and direction of the vent.
The siraightness of the barrel may be ascertained by holding it up to the light
and reflecting a straight-edge on the different parts of the bore, by which means an
experienced eye readily detects any inaccuracy in the bore. The small or ninndard
plug should pass freely through the whole length of the barrel, including the
threads for the breech-screw, and the bore should not admit the large or limit plug.
LOCKS. 177
The (jroiweit shnuM be carefully examined to sue that they arc formed according
to the pattern, and that they are even and uniform throughout.
The breec'i-screws will be examined to sec that they are of the proper dimensions,
are sound in every part, and have good threads ; they are case-hardened. The
screw must be tried in the barrel, to see that it occupies all the threads in the tap
of the barrel, and that it is not loose after entering three threads.
The vent should enter the bore of the barrel clear of the end of the breech-screw.
JInrlcs. — Barrels condemned for defects detected after proof or at any time in the
course of inspection, arc marked with the letter C, struck in deeply; those finally
received are stamped, in addition to the proof-mark, with the year of fabrication on
the top of the barrel, in the direction of the axis of the barrel, ending at .25 inch
from the breech.
Cones.
Verify the dimensions, exterior and interior, and the thread of the screw. See
that the upper part of the cone is properly hardened and free from cracks or flaws.
Locks.
Examine all the limbs, to sec that they are soundj well filed, and of the proper
form.
Httmmcrn. — Verify the dimensions and form carefully with the proper gauges;
see that they are properly case-hardened, especially in the head, knife edge, and
cup for the cone.
Tumblers must be verified separately, with great care, and their hardness tested.
Sprinija. — The strength of the lock-springs, as indicated by the weights they
require to bend them up to the cock-notch without causing them to belly or bend
beyond a straight line, is as follows:
Alain-spring of riffe musket, 1S.55 7f) to 75 pounds.
Sear-spring of each, about 20 "
Sprinff-pronf, No. 1. — Shows when the main-springs- are evenly tempered, and
will weigh from 70 to 75 pounds without bending beyond a straight line-, setting, or
breaking, by bringing them to the standard mark.
Spring-proof, No. 2. — The main-springs are all required to stand in the position
of full cock, in a spring-proof which holds 35 at one time, in the same position as
they are held in the lock, for twelve hours, to test their strength and soundness.
Scrcicn. — Examine the forms of the stems and heads of all screws and the cutting
of the threads, and gauge them ; see that they are properly hardened.
Lock-jilntes. — Verify with the proper gauges the form and dimensions, the
accuracy of the position of the holes, and the threads of those which are tapped;
see that the plate is sound and free from cracks and flaws, especially about, the
tumbler-hole, and that it is well hardened.
Fiuuhcd loci-ii. — The locks having been put together, gee —
1. That they are clean in the inside.
12
178 ORDNANCE MANUAL.
2. That the scar works freely when the scar-screw is driven ns far as it will g*|
ami that, the nuse is sufficientlj' strong and falls properly into the notches of the
tumbler.
3. That the bridle has no cracks or flaws about the holes for the tuiublcr-pivot
and screws.
4. That tiic springs are well bent and of good proportions, that the fixeil branches
fit close to the loek-platc, and that the moveable branches swing clear of it, without
having too much play.
6. That the slits of the screw-heads are not defective.
6. That the arbor and pivot of the tumbler fit accurately in their holes.
7. That the hook of the tumbler does not fall below the edge of the lock -plate
when the cock is down.
8. That the notches of the tumbler are sound and smooth, ami that tlio tumbler
fits and turns well.
9. That the main-spring swivel is sound, by snapping the hammer several times
on the bare cone.
10. That the hammer fits well on the scjuare of the tumbkr, and that it does not
rest on the lock-plate when screwed up tight, and that it has the proper set in rela-
tion to the cone.
11. That all the i>arts work well together.
Marks. — The place and j'car of fabrication are stamped on tiic face of the lock-
platc — the year in rear of the hammer, and the name of the place in front.
Finished arm. — The initials of the finish inspector and of the master armorer
arc stamped on the rear end of the face of the stock, opposite the lock, with italic
letters.
Mountings.
The forms and dimensions are verified with the appropriate gauges and patterns.
The trigger should be well fitted to the guard-plate, with as little lateral play as is
consistent with its free movement. The form, size, and threads of the screws
should be carefully examined. The letters C. S. are marked on the tang of the
butt-plate.
Ramrods.
The temper of the rod is tested by springing it in four directions, with the point
resting on the floor. The musket ramrod should bend 6 inches from a right line
joining the ends: the rod should spring back perfectlj- straight, without setting.
Its soundness and freedom from flaws and cross-cracks are ascertained by the sound
it gives when suspended by one end and gently struck with a piece of metal, and by
passing it over the edge of a block of wood or the closed jaws of a vice, pressing
down the ends at the same time aad turning the rod. so as to present every side
successively to inspection. Rifle and pistol rods are subjected to the last tests only.
The diameter of the rod and the tap of the screw for the wiper are rerilied with the
proper gauges. The length is also verified.
STOCKS. 179
Baijonets,
The form and dimensions of the baj'onet'are verified with the proper gauges; the
temper is tried by springing the bayonet attached to the barrel, the point resting on
the floor. In case of doubt, the temper of the bayonet is definitely proved in the
following manner :
Two iron staples arc fixed in a piece of oak plank on a workbench, 16§ inches
apart; one of them serves as a bridge, and has notches to receive the blade — the
other serves as a staple fpr holding the point of the bayonet close to the plank : the
bayonet is fixed on a barrel, to the butt of which is fastened a brass ball weighing 6
pounds : so that, by inserting the point of the blade in the staples, the face and
back resting alternately on the bridge, the blade sustains a weight of 9 pounds,
which springs it about § of an inch. In this situation the blade is also examined
to detect flaws and croas-cracks. It should not remain bent after this trial.
The inspector then seizes the blade near the point and strikes the elbow smartly
on the workbench, to ascertain that the welding is sound.
If the proof shows no defects, he verifies the dimensions and bore of the socket
and the accuracy of tho channels. He examines the dimensions of the clasp, to
see that it fits well to the shoulder ; that it turns evenly, without binding in any
part ; that the stop is well placed and firmly set; that the clasp-screw and its thread
in the stud of the clasp are well cut; that the elbow has the proper form and
dimensions.
Marks. — Bayonets are marked on the face of the blade, near the neck, with the
letters C. S.; those rejected for defects that cannot be remedied arc marked with
the stamp of condemnation.
Stocks.
■ The examination of the stock will be directed —
1. To the quality of the wood: that it has good, straight grain, is well seasoned,
and free from sap and worm-holes.
The degree of seasoning is indicated by the smell of the wood at a fresh-cut
place; by the appearance of the lock and barrel, etc., when removed from the
stock; they will be rusted by unseasoned wood; by rolling a thin shaving between
the fingers : it will crumble if the wood be well seasoned, otherwise it will be tough
and will bend.
The medium weight of a well-seasoned musket-stock is 2 pounds ; a stock made
of good walnut will not weigh less than 1 pound 13 ounces.
2. To the workmanship: that it is free from splits, especially about the barrel-
groove and heading ; that it has not been split and glued up; that the grooves and
beds are of the proper forms and dimensions; that the roundings for the bands are
smooth and accurate; that the handle and comb are of the proper size and form;
that tho stock has the proper fall or crook, and is of the right length ; that tho
holes arc well drilled, and that those for the wood-screws have good threads.
In examining the bed of the lock, see —
1. That all the edges are sharp and smooth.
180 ORDNANCE MANUAL.
2. Tliiit tlic beds of the scar-screw ami seiir-spring screw arc not bored down to
the friRger or to the breech-screw.
3. Tliut tlio beds of the niuin-sprin;; and main-spring screw do not penetrate to
the barrel.
4. Tliat the hole for the tang of the sear is as small as possible, so that the soar
shall not be wood-bound.
f). That the wires fit well in their holes,
Mitrkii. — That the stocks inspected arc marked on the left .«idc with the stamp of
approval (the initials of the inspector's name) or of condemnation, as tho coao
may bo.
Appendages.
litiU-iirrfwii and viprrn are examined by screwing them on a piece of runirod
furnished with a handle, to verify the accuracy of the screw-thread; the temj>er of
tho branches is tested by prc.';^:ing the points on a piece of hard wood, in which
proof they should spring back to their proper form.
Scrrw-drircm, by inserting the blades in a vice, or in a slit made for the purpose,
and twisting them with the hand. Test the strength and size of the cone-wrench
by putting it on a square socket and wrenching it by hand.
Other implements are examined by applying the appropriate patterns, etc.. and
their soundness may be further tested by striking them a smart blow with a ham-
mer.
Finished Arms.
Finished arms offered for inspection must bo taken entirely to piecei, and each
part must bo examined ns above directed; if the parts have been previously in-
spected, see that they have suffered no suljsequent injury. This being d'>ne, the
arms will be put together and examined in their complete ^tate. Some of the arms
in every lot should be put together by the inspector himself.
The inspector will examine the finished arms on every side, to see that the parts
are well fitted together: he will verify the principal dimensions and forms by
means of the appropriate gauges and patterns.
Jiarrel. — The diameter of the bore must be verified with the standard and limit
gauges. Tho barrel should enter the groove of the stock to the depth of half its
diameter, and should bear well in the whole length of the groove, particularly at
tho breech. The vent should be accurate in its dimensions, position, and direction,
and a wire should be passed into the vent through the cone and cone-seat, to see
that they are free. The cone should be examined, to see that it is sound. The
shoulders of the breeeh-screw should fit close to the end of the barrel, and it must
be free from cracks or flaws about the tang-screw hole : the tang-screw should be
perpendicular to tho tang. The bore of the barrel should be clean and bright.
Ramrod. — The fitting of the groove is ascertained by drawing and returning the
rod smartly several times, to see that it holds well and does not stick too tight ;
FINISHED ARMS. IgJ
the pistol-carbine ramrod should hold more firmlv than that of the musket • the
ramrod must bear on the rod-stop, and in that position its head should not project
beyond the end of the barrel : it should fill the groove well ; the open part of the
groove should be in the centre of the stock, the covered part in the middle of
the thickness of the stock, between the outside and the bottom of the barrel-groove
and the rod should not interfere with the front side screw. '
f{aj,onct.-The socket of the bavonct should be a little below the muzzle of the
barrel at the upper end. Work the clasp, to see that the ramrod does not interfere
with ,t, that it bears well on the shoulders, that the clasp-screw holds well, that the
stock ,s firmlv fixed, and that the clasp moves evenly, without binding: the blade
of the bayonet should set outward a little toward the point. To try the strength
and temper of the bayonet when fixed, spring it smartly in four directions, toward
the back and face and each edge, resting the point on the floor, and grasping the
butt of the stock with the right hand and the middle of the barrel with the left
Examine the fitting of the bayonet to the barrel, and see that the inside of the
socket IS clean and free from rust, and that the bayonet-stud is well bra/.cd and of
tlie right dimensions.
/.oc/..-Examine carefully the action of the lock: snap the hammer on the cone,
to see that it fits well. Let the hammer down several times, to judge of the working
of the lock. See, also—
1. That the interior parts are not wood-bound.
2. That the hammer stands ofl!' (0.02 inch) from the lock.
^ 3. That it does not go ofl^ at half-(*)ck when the trigger is.pulled hard.
^ 4. That it goes neither too hard nor too easily when cocked.
.. 5. That it docs not stop at half-cock.
6. that the trigger is steady at cock and half-cock, and free when the hammer is
down.
7. Th-it the fall of the hammer is not stopped by the heel of the tumbler before
It touches the cone.
8. That the hammer has sufficient sweep : that it falls evenly, without a jerk, and
that the knife edge passes freely over the plate.
Exjimine the soundness of the hammer at the tumbler-hole.
In examining a finished lock by itself, observe the rules laid down above; see
that the lock-plate fits accurately in its bed, and that the wood around it is full and
sound.
Mount{ny.,.-The front part of the trigger at half-cock should be nearly perpen-
dicular to the surface of the guard-plate; the slit for the trigger should be of the
exact width, so that the trigger shall have no lateral motion.
It is important that the guard-plate should bear firmly on the wood in every
part; as, otherwise, by driving the tang-screw too hard, the trigger might be
brought too close to the sear and the action of the lock be thus interfered with.
The butt-plate should be well fitted in the centre of the stock.
The bands should fit sm..othly at (he shoulders and closelv to the stock and

barrel, but not no tight as to require a great effort to remove them. The band-
ipringR should not l>e too deeply .set : they should spring hack freely when prcoKcd
down ; the holes lor the wires ishoiiid not interfere with the liarrel or ramrod

All the mountings should fit smoothly to tho stock. The stock should hare the
proper fall or crook, which is ascertained by applying tho |)attcrn and by trying
the piece in the position of ainiins:.
By sighting along the barrel, i: will be seen whether it is well stocked, wlietbar
the bands, the front and rear sights and the bayonet are well set.

General Directions.
The inspector is not restricted to the particular examinations above mentioned;
be will make any other examinations which he may deem necessary to ascertain the
quality of any |iart of the arms and their confirrmity to the standard models ; if be
discover or suspect any attempts on the part of the workmen to cover or ccmcea)
serious defects, he will subject the arms to the most severe scrutiny, in order to
detect such defects.
In tho inspection of contract arms, the inspector will judge of the quality of
materials and workmanship by the rules which govern in like cases at tho national
armories; that is, he will reject such arms or parts of arms as would be condemned
at the national armories, and ho will recoire such as would be approred at the
national armories — without exacting, in any case, more rigid conditions than are
enforced at thoi^c establishments.
The ordnance officer charged with tho inspection of arms, or the master armorer
at a national armory, will cause at least one in ttrmiy of each lot of arms passed by
a 8ub-in8pect<ir to be taken to pieces in his presence, anil he will examine them
strictly, agreeably to the foregoing directions, before affixing his stamp of approral
on the finished arms, all of which must be examined by him.
Mnrkt. — As a general rule, every part condemned on inspection will be indelibly
marked with the letter (', and every principal part ajiproved will be marked with
the initials of the inspector's name. C.ire must be taken that the marks of approval
arc not stamped so deep as to be injurious.
Finished arms approved in inspection will be marked on the left face of the stock
with the initials of the name of the principal inspector, and the year of inspection.
Report of Inspection of Barrels.
After the inspection of each lot of barrels, the inspector will make a slaicmeDt,

the Ordnance Regulations.
Broinied Arms.
The barrels of rifles are browned at the armories before being received fof the
service; the locis, ramrods, hraid-Dpriiiys, trir/r/erg and semes are not browned.
The parts of these arms should be thoroughly inspected before browning, and the
finished arm after being browned.
INSTRUCTIONS FOR BROWNING ARMS.
Materials for Browning Mixture,
li oz. spirits of wine.
IJ oz. tincture of steel. y
i oz. corrosive sublimate,
li oz. sweet spirits of nitre.
1 oz. blue vitriol.
3 oz. nitric acid.
To be mixed and dissolved in 1 quart of soft water; the mixture to be kept in
glass bottles, and not in earthen jugs.
Previous to commencing the operation of browning, it is necessary that the
barrel or other part should be made quite bright with emery or a fine, smooth file
(but not burnished), after which it must be carefully cleaned from all greasiness; a
small quantity of pounded lime rubbed well over every part of the barrel is the best
for this purpose. Plugs of wood are then to be put into the muzzle of the barrel
and into the vent, and the mixture applied to every part with a clean sponge or rag.
The barrel is then to be exposed to the air for twenty-four hours ; after which time
it is to be well rubbed over with a steel scrateh-eard or scratch-brush, until the rust
is entirely removed; the mixture may then be applied again, as before, and in a
few hours the barrel will be sufficiently corroded for the operation of scratch-brush-
ing to be repeated. The same process of scratching off the rust and applying the
mixture is to be repeated twice or three times a day for four or five days, by which
time the barrel will be of a very dark brown color.
When the barrel is sufficiently brown and the rust has been carefully removed i
from every part, about a quart of boiling water should he poured ov«r every part
of the barrel, in order that the action of the acid mixture upon the barrel may be
destroyed and the rust thereby prevented from rising again.
The barrel, when cold, should afterward be rubbed over with linseed oil or
sperm oil. It is particularly directed that the steel scratch-card or scratch-brush.,
be used in the place of a hard hair-brush, otherwise the browning will not be
durable nor have a good appearance.

Packing Arins with Straw.
In the field, or under other circumstances, when the proper arm chests arc not
on baud, it may sometimes be necessary to pack arms in this manner.
The interior dimensions of a box for 20 muskets may be the same as for the regu-
lar packing-box.
The straw should be long, perfectly dry, and free from dust ; rye straw is the
best; hay should not be used: about 25 pounds of straw are required to a box.
To prepare the miiakit for packiiiff. — Oil it; let down the hammer, pass the bay-
onet up to the socket into the guard-bow, on the right side, in front of the trigger.
MaJ{c a rope of about 40 straws, slightly twisted, and 40 inches long ; wrap it
about the musket, commencing on top of the hammer, going round the bayonet
below, again over the hammer and round the piece in front of the guard, then over
the socket of the bayonet near the neck, and wrapping the rest around the handle
of the stock.
Lay a bed of straw 2 inches thick in the bottom of the box : in the middle and
lit 6 inches from the ends, place three cushions of straw (J inches thick and 12
inches wide. Put in a tier of 10 muskets crossing each other, the butts resting
alternately against the ends of the box, the guards uppermost, and the hammers
bearing on the cushions. Put small trusses of straw under the upper and middle
bands, by raising the muskets at one end and then pressing them down between
the others. Pack, between the butts, wads of straw 8 inches long, made of a hand-
ful of straws folded in three ; cover the guards and guard-bows with the ends of
the straw that form these wads, which will be still about 12 inches long. Put in
another tier of 10 muskets in the same manner, making the cushions four inches
thick. Pack the implements in straw in the vacant spaces. Fill the box with
straw, so that the cover shall require strong pressure to keep it down. Put two
hoops around the box, at IS inches from the ends.
Other arm^, swords, etc., are packed in a similar manner.
PRESERVATION OF ARMS. 187
Arms should not he wrapped in paper, unless it bo oiled, as it attracts moisture
more readily than straw does.
PRESERVATION OF ARMS IN STORE.
Arrangement and Manner of Storing Ar7ns.
Arms are kept at the arsenals either in the boxes in which they arc received from
the armories, or in racks.
Those of each kind are kept separate, and they are arranged according to
the model, the place and j-ear of fabrication, and the time when they were last
cleaned.
New arms are kept distinct from those which have been repaired.
Each parcel should have a label, indicating the kind, number, model, date of
their receipt in store and of their being last cleaned.
The manner of keeping arms at the arsenals is determined by the chief of the
Ordnance bureau, according to the peculiar circumstances of each case, and racks
are constructed for them only in pursuance of special authority from the Ordnance
oflBoe; without such authority, they are kept in boxes. The form and arrangement
of the racks vary with those of the room in which they are placed, so as to use the
space to the best advantage and give light and air to every part of the room. The
usual arrangement of racks for muskets is to establish two rows of double racks,
two tiers high, perpendicular to the length of the room, leaving alleys around the
room next to the walls, and in the centre, if necessary. The bayonets are passed
through the middle band swivel, the socket covering the top of the ramrod. Other
racks of a similar kind may be made for rifles, carbines, etc. Pistols are suspended
by the guard-bows, on hooks driven into the faces of the musket racks, or iuto the
joists, or into strips attached to the walls of the building.
When there are neither racks nor boxes prepared, the arras are stored in dry
rooms, arranged in rows apart from the walls, standing on their muzzles and sup-
ported by frames to prevent them from pressing too much on each other. The
bayonet should be unfixed and passed through the swivel. They should be covered
with tarpaulins or cloths, if necessary, to protect them from dust.
Arms of peculiar kinds, and arms to be repaired, are kept separate from others ;
as also arms unserviceable or condemned to be broken up.
Limbs and spare parts intended for repairs of arms should be kept in store by
themselves, in a dry place, classed according to the kind of arms and to the model
and year of fabrication, and labelled accordingly.
Musket and rifle barrels and other long barrels, standing on their muzzles ; the
piles covered from the dust with tarpaulins supported so as not to touch the barrels.
Pistol barrels, bayonets, and other small jjarts, in drawers or boxes, properly labelled.
Stocks, in square piles, in the attic or upper story of the building.

ORDNANCE MANUAL.
Care of Ar7ns iii Store.
Arms when received at an arsenal should be unpacked and carefully examined,
to detect anj' damage suffered in transportation ; they should be cleaned and oiled,
if they require it. Those arms which are not to be placed in racks should be
returned to the boxes, laid in looseh' but safely, and the cover slightly fastened
down, so that they can be readily examined.
All arms in store should be freijuently examined, to see that they do not become
rusty. Those which are found to be rusted should be immediately cleaned and
again oiled. Browned arms, if affected with specks of rust, should be rubbed hard
with linseed oil; and if the appearance of the browning indicate that the acid is
not neutralized, care should be taken to examine the arms a;:ain within a short
time, as it maj' be found necessary to remove and renew the browning: but this
operation should not be performed without special authority from the chief of the
Ordnance bureau, on the report of a duly authorized inspector.
Arms which are to be repaired should be oiled and taken caro of in the same
manner as serviceable arms. Irreparable arms, the parts of which can be used
for repairs, should be oiled. Similar remarks apply to spare parts for repair of
arms.
Sjirrm oil should be used for greasing arms.
Empty boxes, from which iln- arms in racks arc taJicn, should be kept, with all
the parts belonging to them, in the attics or other dry situations.
The storehouse for arms should be aired in clear, dry weather.
Issuing Arms.
The Ordnance regulations prescribe the manner of issuing arms to the troops
under the various circumstances of service, and to the slates, for arming the
militia.
All arms issued from an arsenal should be carefully examined before delivery,
cleaned, and put in good order; if intended for transportation, the.v should be
oiled, if necessarj', after cleaning, and carefully packed.
PRESERVATION OF ARMS IN SERVICE.
The officers, non-commissioned oflScers, and soldiers should be instructed and
practised in the nomenclature of the arms, the manner of dismounting and mounting
them, and the precautions and care required for their preservation.
Each soldier should have a screw-driver and a wiper, and each squad of ten a
band-spring and tumbler punch, and a spring-^ce. No other implements should be
used in taking arms apart or in setting them up.
In the inspection of arms, officers should attend to the qualities essential to ser-
vice, rather than to a bright polish on the exterior of the arms. The arms should
be inspected in the quarters at least once a month, with the barrel and lock separated
from the stock.
TAKING ARMS TO PIECES. 189
Taking Arms to Pieces.
To taJce apart the rijie jnusJcet, model 1855 —
1. Unfix the bayonet.
2. Put the totnpion iu the muzzle of the barrel.
3. Draw the ramrod.
4. Turn the tang-screw.
5. Take off the lock : to do this, first put the hammer at half-cock, then unscrew
partially the side screws, and, with a slight tap on the head of each screw with a
wooden instrument, loosen the lock from its bed in the stock; then turn out the side
screws, and remove the lock with the left hand.
6. Remove the side screws, taking care not to disturb the washers.
7. Take otf the upper band.
8. Take off the middle band.
9. Take off the lower band.
10. Take out the barrel.
In doing this, turn the musket horizontally, with the barrel downward, holding
the barrel loosely with the left hand below the rear sight, the right hand grasping
the stock by the handle; and if it does not leave the stock, tap the tompion in the
muzzle gently against the ground or floor, which will loosen the breech end from the
stock. This is preferable to lifting the barrel out by the muzzle, because if the tang
of the breech-screw should bind in the wood, the head of the stock would be liable
to be split by raising the muzzle first.
The foregoing parts of the rifle musket are all that should usually be taken off or
dismounted.
The soldier should never dismount the baiid-sj)r!ncfs, fjuard, side screw, washers,
hult-plate, rear sight, cone, and cone-seat screw, except when an otPicer considers it
necessary. The breech-screw should be taken out only by an armorer, and never in
ordinary cleaning. The lock should not bo taken apart, nor the bayonet-clasp taken
off, except wlicn absolutely necessary iu the opinion of an officer. If proper and
regular care he taken of the arm, this will he very seldom necessari/.
The parts which are specially assigned to be dismounted by an experienced
armorer will be stated in their regular order following No. 10, viz:
11. Unscrew the cone, keeping the wrench well down on the square of the cone,
to prevent the corners from being injured.
12. T.ake out the cone-seat screw.
13. Take out the upper, middle, and lower band-springs, using a wire punch of
proper size.
14. Take out the side screws.*
*The guard, butt-plate, and side-screw heads have concave slits, for which the screw-driver is
adapted: this lessens tiie danger of the stock being marred by accident or carelessness in letting
the screw-driver slip out while in the act of turning the screw. Great care should be observed to
prevent injury iu this particular.

18. Keinove tlie rear oijjht by turning out tlie leaf-f>pring screw, which will release
the Bight from the barrel.
19. Turn out the hrceeh-screw by means of a " brcecli-ser''w wrench" ruitcd to
the tenon of the breech-Hcrew. No other wrench should ever be uned for this pur-
poHc, and llu' barrel hliould be held in clamps fitting neatly the breech.

5. The tumbler-screw.
6. The tumbler. This is driven out with a punch inserted in the screw-bole, which
at the same time liberates the hammer.
7. Detach the main-spring swivel from the tumbler with a drift-punch.
Assembling Arms.
The lock and the mu^kel are put together in the inverse order of taking them
apart.
THK LOCK.
1. The main-spring swivel. 2. The tumbler and hammer. 3. The tumbler-
screw, i. Bridle and screw, i. Sear and screw, ti. Sear-spring and screw.
7. Main spring.
Before replacing the screws, oil them slightly with good sperm oil, putting a
drop on the point of the screw; also, on the arbor and pivot of the tumbler;
between the movable branches of the springs and the lock-jdatc : on the hook and
Botches of the tumbler. After the lock is put together, avoid turning the screws in
so bard as to make the limbs bind : to insure this, try the motion of each limb
before and after its spring is mounted, and see that it moves without friction.
THE MrSKET.
1. The barrel. Drop the barrel into its place in the stock, and squeeze it down
with the band ; give the butt of the stock a gentle tap against the floor, to settle
the breech end of the barrel against the head of the stock.
CLEANING AND CARE OF ARMS. 191
2. Put on the lower band with the letter U upward, being careful not to mar the
stock or barrel in sliding it into its place ; apply the thumb to the band-spring, to
see that it plays freely.
.3. Put on the middle band ; and,
4. The upper band, in the same manner.
5. The lock. Half-cock the hammer ; take the lock in the right hand, with the
main spring and sear toward you, holding the stock with the left hand by the .'swell,
with the butt between the knees. Enter the lock fairly into the lock-bed, taking
care to keep the arm of the sear clear 'of the trigger: press the plate well down
into the wood, and then turn the musket over, holding the lock and stock together
/with the left hand.
6. With the right hand, turu in the side screws, after having touched their screw-
threads with oil. Observe that the point of the rear screw is flat, and should not
project beyond the plate, to interfere with the hammer. The front screw has a
round point.
7. Turn in the tang-scrcw, after having oiled the screw-thread. Be careful to sec
that each of these screws are turned firmly home, but not forced. Observe that the
lock plays freely, without friction, and that no limb is bound by the wood.
8. Return the ramrod.
9. Kcfi.x the bayonet, after having oiled the clasp and socket to prevent chafing.
10. Replace the tompion. Oil the stock well with sperm or linseed oil ; let it
stand a few hours, and then rub it with a woollen rag until the wood is perfectly
dry. Repeat this from time to time, and it will produce a polish which moisture
will not affect.
Linseed oil is the best for this purpose, and it should be used while the arm is
dismounted.
Cleaning and Care of Anns.
TO CLEAN THE BAHKEL.
1. Stop the hole in the cone with a peg of soft wood ; pour a gill of water (warm,
if it can be had) into the muzzle ; let it stand a short time, to soften the deposit of
the powder ; put a plug of soft wood into the muzzle, and shake the water up and
down the barrel well; pour this out and repeat the washing until the water comes
out clear ; take out the peg from the cone, and stand the barrel, muzzle downward,
to drain for a few moments.
2. Screw the wiper on to the end of the ramrod, and put a piece of dry cloth or
toic round it, sufficient to prevent it from chafing the grooves of the barrel ; wipe
the barrel quite dry, changing or drying the cloth two or three times.
3. Put no oil into the vent, as it will clog the passage, and cause the first cap to
miss fire ; but, with a slightly oiled rag on the wiper, rub the bore of the barrel and
the face of the breech-screw and immediately insert the tompion into the muzzle.
4. To clean the exterior of the barrel, lay it flat on a bench or board, to avoid
bending it. The practice of supporting the barrel at each end and rubbing it with
198 ORDNANCE MANUAL.
a strap or buff-ctick, or with the ramrod or any other instrument, lo hunn't'h it, In
pernicious, and should be strictly forbidden.
5. After firinj;, the barrel Hhould always bo washed as goon as practicable; when
the water comes olT clear, wipe the barrel dry, and pass into it a rag moistened with
oil.
Ah rust and dirt are produced by e.\|)loding caps or primeri^, ulthnu^^h no charge
be fired, the parts of the barrel and cone exposed should be carefully wiped and
oiled after such practice.
Fine Jlour »/ emery cloth is the best article to clean the exterior of the barrel.
TO CLKAN TllK I.OCK.
Wipe every part with a moist rag, and then a dry one; if any part of the interior
shows rust, put a drop of uil on the ])oint or end of a piece of soft woud dipped into
flour of emery ; rub out the rust clean and wipe the surf;ice dry ; then rub every
part with a slightly oiled rag.
When a lock has, from any cause, become gummed with oil and dirt, it may be
eleane<l by being boiled in soap-suds or in pearlasb or soda water, to luusen Ibe
thick oil : but heat should never be a]iplied to any part of it in any other way.
TO CI-KAN THE MOfNTINGS.
For the mountings, and all of the iron and steel parts, use fine flour of emery
moistened with <jil, or flour of emery cloth.
For brafs, use rotlen-st6ne moistened with vinegar or water, and keep free from
oil or grease. I'se a har<l brush, or a piece of soft pine, cedar, or crocus cloth.
Remove dirt from the screw-holes by screwing a piece of soft wood into them.
Wipe clean with a linen rag, and leave the parts slightly oiled.
In cleaning the arms, great care should be observed to prcunie the ifualiliei etten^
tial to territr, rather than to obtain a bright polish.
BurniihiHtf the barrel (or other parts) should be strictly avoided, ai it tends ta
orook the barrel, and also to destroy the uniformity of the exterior finish of the
arm.
It is not essential for the musket to be dismounted every time that it is cleaned ;
for, after firing it in fine weather, or when there has been no chance for the wet to
get between the barrel and the stock, it can be perfectly cleaned in the following
manner —
Put a piece of rag or soft leather on the t«p of the cone, and let the hammer
down upon it ; pour a gill of water into the muzzle, carefully, so that it does not
run down the outside: put a plug of wood into the muzzle, and shake the gun op
and down, changing the water rei'catedly until it comes out clear. When clear,
withdraw the leather, and stand the musket on the muzzle for a few moments ; then
wipe out the barrel (as given in the second rule for cleaning), and also wipe the
CLEANING AND CARE OF ARMS. 193
extcri..r of the lock and the outside of the barrel around the cone and cone-seat
first with a damp ra-, and then with a dry one, and lastly with a rag that has been
slightly o.led. In this way, all the dirt due to the firing may be removed without
taking out a screw.
If. however, the hammer be observed to work stiff, or to grate upon the tumbler
the look must immediately be taken off and the parts cleaned and touched with oil
To change the co„e, when it is broken or worn out.— After removing the old cone
enter the new one carefully with the fingers, before using the wrench, in order to
avoid bruising the thread in the barrel.
It is very important to use no other implenwnts than those before mentioned
By using nails to drive out the wires, their holes are enlarged. The main spring
should never be heated for the purpose of either raising or lowering its temper
this destroys the elasticity of the spring, and the lock no longer gives fire.
The notches of the tumbler, the main .spring, swivel, and in°general, all the joints
of the lock should be frequently oiled, after first wiping off the hard grease and the
dust.
Broiccd arms are cleaned by rubbing them hard with an oiled rag until the oil
is well incorporated with the browning, or by rubbing them with beeswax on a rae
or cork. °
Rifled arms should not have the ramrod spr,u,g in the bore with unnecessary
force. It batters the head of the rod, and wears injuriously the grooves. The
soldier should let the rod slide down gently, supported by the thumb and finger •
and the inspecting ofiicer can satisfy himself of the condition of the bottom of the
bore l,y gently tapping with the rod. The faca of the breech can be polished after
^washing, by means of a cork fixed on the wiper or ball-screw ; the polished surface
can be seen if the muzzle is turned to the light.
Besides all the precautions in dismounting, remounting and cleaning, which have
been pointed out in the foregoing pages, habitual care in handling the arms is
necessary to keep them in good and serviceable condition.
In ordering arms on parade, let the butt be brought gently to the ground, espe-
cially when the exercises take place on pavements or hard roads. This will save
the mechanism of the lock from shocks, which are very injurious to it, and which
tend to loosen and mar the screws and split the wood-work.
In sfac/nng arms, care should be taken not to injure the bayonets by forcibly
straining the edges against each other. The stack can be as well secured without
such force being used.
No cutting, marking, or scraping in any way the wood or iron should be allowed :
and no part of the gun should be touched with a file. Take every possible care to
prevent water from getting in between the lock, or barrel and stock. If any should
get there, dismount the gun as soon as possible, clean and oil the parts as directed,
and see that they are perfectly dry before reassembling them.

INSPECTION OF ARMS IN SERVICE. OR WHICH H Wr BEEN IN
SERVICE.
fmjilrniciitii. — Standard and limit-gauges for the bore, lirnit-guagcx for the exterior
of the barrel, and a gprcw-platc with taps for the holes of the lock-plate.
The following are the principal points to be aUcmUd to in the inspection of
arms —
The arms being taken to pieces and cleaned.
HAnitKI.. — DffrcU fur ichtrh tht barrel mtitt br eondeiniird a* nnjtt /or trrriee. Tho
large pnacc entering the whole length of the barrel. The email or standard gauge
not entering, unless the diminution of the bore be caused by the liarrel being in-
dented or bent — defects which may be remedied. A diminution of the exterior
diameter at the hreech or at the muzzle, so as to enter the'small receiving guagu :
this diminution is 0.1 inch at the breech; O.O.'l inch at the muzzle for arms with
bayonets, and 0.(t40 inch for arms without bayonets. A diminution of more than
0.25 in the length of a pistol barrel, or 0.5 inch in the length of other barreli.
Splits, cross-cracks, and other serious defects, caused either by bad workmanship or
by use.
Examine the barrel carefully, to see if it have any of the above defects, and, if
■o, mark them with a file, when not very apparunL See if the bayonet-stud be broken
or too much worn, if the cone-seat be perfect, and its thread in good order and the
▼ent unobstructed. If the breech-screw be not tight after entering 5 or C threads,
or if it can be screwed down by hand without the use of a wrench, if the thrcada be
not sharp and sound, if the plug *j not fill up the whole Ixix of the female screw,
if the tang bo broken or cracked at the screw-hole, or if, when the breech-screw u
in, the tang bo not even with the upper surface of the barrel, a new breech-screw is
required.
Conk. — Examine the chamfered end of the cone, to sec that it be not broken or
bruised ; examine abo the thread and the rent.
Bayonkt. — A bayonet is considered unserviceable if the blade be I inch too short.
Bee if it bo sound and perfect in all its parts, and if it fit the barrel ; also, if the
elasp be in good order and turn freely.
Lock. — See if the fixed branches of the gpriuga fit close to the ]«ck-plate, if the
movable branches be clear of it, and if any of tht parts be wood-bound.
Have the springs and the bridle of the tumbler renewed when their pivots are
hroken. There should be an equal space between the lock-plate and the scar, the
tumbler and the hammer.
If the »car rub on the plate, have it adjusted. The friction of the tumbUr may be
eansed by the bridle being badly pierced, in which case renew the bridle. If the
hammer rub on one side only, have it adjusted: if it rub everywhere, the arbor of
the tumbler does not project suflSciently, and the tumbler should be renewed. If the
not(htt di' the tumbler be broken, or the edges too blunt, have them dressed; if the
hook of the tumbler project beyond the edge of the lock-plate when the hammer is

let down, the tumbler should be renewed. The arbor and the pivot of the tumbler
should fit well in their holes. Examine ihc star closely, and have it renewed when
the nose is too thin or is worn on the side next the lock-plate, although it may be
perfect on the exterior. If the hammer be not steady, the tumbler should be renewed.
Try the action of the hammer, to see that it explodes the cap with certainty.
Renew the Inck-plaie when the holes arc too much worn to be dressed over. Renew
every limb that is broken or cracked, the screws which arc too much worn, or of
which the stems are bent or the slits too much enlarged.
Mountings. — See if the parts be complete and sound.
If the tantj-KcrcxB do not fit tight in the screw-hole of the guard-plate, renew
whichever part is defective.
Ramrod. — See if it be sound and have a good thread and be of the proper length;
otherwise, replace it.
Stock. — Examine carefully the bed of the lock, and the holes for the band-springs.
Press the thumb against the /uciiKjn, to see if they be split at the holes for the side
screws, and renew the stock if it be split there or at any other part to an injurious
extent.
The a7'm8 complete.
Are inspected according to the rules before laid down for the inspection of finished
arms ; due allowance being made for the necessary wear in service.
REPAIRS OF ARMS AT ARSENALS.
When arms which have been in the hands of the troops are turned into store at an
arsenal, they should be inspected by a master armorer, under the supervision of an
oflBcer, and classed as follows —
1. Serviceable arms.
2. Anna requiring repairs.
3. Irreparable arms.
Arms requiring repairs arc classified according to their kinds and models and
to the extent of the repairs required. Each arm should be marked with a number,
and the requisite repairs should be noted on the register of in.spettion, to guide the
workmen and to govern the is.sue of spare parts required for repairs.
Repairs prohibited.— Tho following repairs beiug always imperfect, the parts
requiring them should be replaced: Cutting oflf a barrel; brazing a patch on a
barrel; brazing a tang on the breech-scrcw ; brazing a bolster on a lock-plate;
reaming out the hole for the arbor of the tumbler; brazing a piece for a tumbler-
hole or a shoulder on the hammer; hammering iu the edge of the hole to make it
fit tighten the square of the tumbler; putting a pivot to a tumbler; twisting the
square of the tumbler to increase the sweep of the hammer; straightening the
arbor; brazing a ramrod; splicing a stock.
The spare parts furnished from the armories are iu soQ^:ra,\ filed, jiniehed, hard-
ened and tempered, including the breech-screw.
196 ORDNANCE MANUAL.
Filtinp fifir part*. — To adjust n icir lock, the flat of the barrel should not
bo filed, but the bolsters of the lock-plutc should be ground.
The hnrrcl should not be touched with a file when it has been injured by rust.
fn rejilaring the hayonrt-ntnd, avoid cutting too deep into the barrel and proclucing a
j)rojcctiim inside; try the small gauge iu the barrel after the operation. In fitting
a new bayonet, dress out the groove of the socket and ream out the socket if
necessary.
lirnzc iiijhKi and bayonet -itudi only, and no other pieces; the solder is comjtosed
of two parts of brass and one of zinc, without any tin.
Irreparable Arms.
Arms arc considered irreparable when both the barrel and stock arc until for
service; or when the arms require very extensive repairs anil the part!« can be made
useful for repairs of other arms. They can be broken up only by special authority ;
and they should, therefore, be oiled and preserved, in order to be submitted to an
inspector, as prescribed in the Ordnance regulations.
When arms are broken up, the parts are classed either as lervieenble, reparnblr.,
or \in$erv\e.eable ; those of the last class should be turned into store as tcrap iron or
tieel, etc.
STRENGTH AND DURABILITY OF MUSKET BARRELS.
To test the strength of musket barrels, model 1855, they have been fired with an
increasing number of cartridges, until the force of the explosion of the first two
cartridges was unable to drive out the other charge.*, and the gas escaped through
the veut, leaving the barrel uninjured.
The strength of the barrel, therefore, furnishes every requisite" security against
the accidents of service and the want of care on the part of the soldier.
E.xpcricnce has shown that a musket barrel may be fired 'JG.OOO times without
becoming unserviceable.
Barrcl.s which are condemned in service are almost always the result of accident,
very rarely from enlargement of the bore or from the diminution of the exterior
dimensions.
The following trials of the strength and durability of the French musket barrel
are taken from the Aide-Memoire. They refer to the smooth bure musket : It is to
be observed that the charge of the French musket was formerly 1(32 grams Troy,
priming included (or 146 grains, exclusive of priming), and is, therefore, consid-
erjibly greater than our present service charge.
In experimeuts made in 1S06, barrels reduced 0.13 inch at the breech bore a
double and triple charge with one ball, or 2 cartridges placed one over the other.
Other trials were made in 1S29, at the manufactory of Mutzig, on arms sent
there for repairs^ which had been a greater or less time in the hands of the troops.
They furnished the following results —
STRENGTH AND DURABILITY OF MUSKET BARRELS. 197
Ist. When a musket barrel is charged with a single cartridge, placed in any part
of it, or with 2 or even with 3 cartridges, inserted regularly, without any interval
between them, there is no danger of bursting ; with 4 cartridges inserted regularly
over each other, or with 2 or even 3 cartridges placed over each other with slugged
balls (or balls driven in, as in a rifle), there is danger only in case of some defect
of fabrication, or some deterioration in the barrel ; with more than 4 cartridges
inserted regularly one over another, or with 2, 3 aud 4 cartridges with intervals
between them, it is not safe to firev
2d. No danger of bursting is occasioned by leaving a ball-screw in the barrel.
There may be danger from a plug of wood driven tight into the muzzle, whun the
barrel has been loaded with 2 cartridges; or from a cork rammed into the barrel to
a certain distance from the charge, with another cartridge over it.
Snow, clay and sand, which may be accidentally introduced into the barrel,
are not dangerous, if they lie close to the charge; but they are so when there is a
space between thcni aud the charge ; in this case sand is the most dangerous, then
clay and snow.
Balls or pieces of iron inserted over the charge were not attended with danger
when placed close to the charge, even when their weight amounted to 11 lb.; but
there is danger from a piece of iron, 0.0 inch square, weighiug i lb., if placed 20
inches or more from the breech.
3d. A barrel with a defect which might have escaped the inspector at the armory,
bore the explosion of 3 cartridges, regularly inserted. After mutilation, which
may have caused a reduction of metal in some parts, it may still bo used with-
out danger.
Finally, the diminutions of exterior diameter which may be produced in ordinary
service are never sufficient to be dangerous. In these trials, barrels oiiginally 0.272
inch thick at the breech did not burst when loaded with 2 cartridges, until the
thickness was reduced to 0.169 inch, and with 1 cartridge to 0.091 inch.

Proof and Inspection of Swords and Sabres.
1st. The dimensions and form of the blade are verified by comparing it with the
model, and by applying the appropriate gauges and patterns, for the length, width,
and thickness at several points, and the curvature, if any.
214 ORDNANCE MANUAL.
2(1. The hladf is then proved, as follows: I.«f. The point is confined by a staple,
and the blade is bent on each of the flat sides over a cylindrical block, the curva-
ture of which is that of a circle 35 inches diameter, the curvature of the part next
the tand bcinji reduced by inserting a wedjje 0.7 inch thick at the head and 14
inches long. 2d. It is struck twice, on each of the flat sides, on a block of oak
wood, the curvature of which is the same as the above. 3d. It is struck twice on
the edge and twice on the back across an oak block 1 foot in dianu-tor. 4th. The
point is placed on the floor and the blade bent until it describes an arc having the
versed sine indicated in the above table. After these trials, the blade i.-< examined
to Bee that it is free from flaws, cracks, or other imperfections, and that it is not
««/ — that is to say, does not remain bent.
The blade of the nrtilleri/ nword is proved by striking each of the sides and
edges twice on a flat block of hard oak wood.
The stamj) of approval or condemnatioti is placed on the side of the blade,
below the tang.
3d. The form, dimeUiSions, and workmanship of the mnuutingi are examined and
compared with the model. After the blade is mounted, the sword is again exam-
ined, and it is struck four times on a hard block of wood, to test the strength of
the mountings. The quality of the brass mountings may be tested by breaking a
certain number, not more than 4 in each hundred, which should be taken from th*
pieces rejected for erroneous dimensions.
4tb. The form, workmanship, and finish of the scnliLardii are examined and com-
pared with the model, and their titting to the blades tested. The sewing of leather
scabbards, and the fastening of the ferrules and tii)S, will be jiarticularly examined.
Steel scabbards are proved by letting fall on them, from a height of 18 inches,
an iron weight of two pounds, 1 inch square at the base: Ist, on one side, just
above the upper band; 2d, on the same side, 6 inches from the tip: 3d, on the
opposite side, just above the lower band. In this proof the scabbard should not
remain indented. The nature of the material (whether iron or steel) may be tested,
if there be any doubt, by using nitric acid, which will leave a black spot on the
steel but not on the iron.
Packing Swords and Sabres.
Packing-boxes for swords and sabres are made ou the same principles as those for
muskets and other small arms, being furnished with packing-boards, or partitions,
made with grooves to receive the scabbards near the hilt and near the point; the
swords are placed in their scabbards, with the hilts and points alternately toward
each end of the box — except the artillery swords, two of which are jilaced in the
length of the box, their points resting on a packing-board in the middle.
\iimber ]iacked in ti box.
30 cavalry sabres. 50 artillery swords.
50 artillery sabres. 50 infantry swords.

Cleaning Sivords and Sabres.
The iron and brass parts of swords and sabre.-* are cleaned in the same manner as
those of muskets. When the oil on the blade of a sword is dried up, it will leave
a spot which may be removed by covering it with oil and rubbing it smartly, after
a short time, with a linen rag. When a leather scabbard has become wet, draw the
blade, and dry the scabbard slowly without heating it; wipe the blade dry, and
pass an oiled rag over it and the scabbard before returning the blade. Oil the
blades of arms in store, and also the scabbards, especially on the seams.

The bridle, .shoe, sole, calf, and russet leather should be tunned witii oak bark:
reject all that has been tanned with hemlock, as such leather ."oon moulds, and the
blacking turns of a reddish color.
The leather s^hould be of the best quality, uniform in thickness, and free from
cuts and fly-holes. Flesh split-leather is not admitted. The buff-leather should be
soft and flexible, free from defects. When freshly cut, it should present a bright
yellow surface ; a brownish yellow color indicates that the hide has been burned by
the lime in tanning. It should be firm without being horny, and not spongy.
See that the hooks of cast-brass are free from flaws, and that the eves are firmly
fastened.

SALTPETRE.
Chapter Ninth.
GUNPOWDER.
Gunpowder for the military service is distinguished as mnnkci, cannon, and mam-
moth powder. Thoy arc all made in the same manner, of the same proportions of
materials, and differ only in the size of the grain.
MATERIALS.
The materials required are saltpetre, charcoal, and sulphur. They should be of
the greatest possible purity, both for the quality of the powder and the prevention
of disastrous accidents in the manufacture.
Saltpetre.
Saltpetre (nitre, nitrate of potassa) is a transparent, white, crystalized salt,
inodorous, anhydrous, of a cooling, pungent, and slightly bitter taste. It generally
crystallizes in six-sided prisms terminated by six-sided pyramids, or in needles
deeply striated, and sometimes contains mother-water in fissures in the longer axis
of large crystals. It is composed of 53.45 nitric acid and 46.55 potassa. Specific
gravity, 2.099 to 2.1. Unalterable, in common air, it becomes deliquescent in an
atmosphere nearly saturated with moisture. It melts at about GB2° into a limpid,
oily-looking liquid, and may be cast into moulds, forming a white, compact mass.
It begins to decompose at about 716°, giving up its oxygen: at a white heat the
decomposition is incomplete, peroxide of potassium remaining. If thrown upon
burning coals, it melts and deflagrates violently. It is insoluble in absolute alcohol
and oils; soluble in water — more in warm than in cold: in dissolving it causes a fall
in temperature; it raises the boiling point of water, and increases its density by
about 0.0077 for each part of saltpetre contained in 100 parts of water.
100 parts of water at 32° dissolve 13.3'2 saltpetre, and tlie solution boils at about 213. S°.

.Saltpetre occure naturally in great quantities, as au efflorescence on the surface
of the earth, in man}' of the warm countries, particularly in India, where there is
suflScieut to supply the wants of the whole world. It also occurs as a saline crust
in caverns in some parts of the globe; and in the vicinity of Monclova, Mexico, it
is found in great purity in veins or mines.
It exists in certain plants, and is formed spontaneouslj' by the decomposition of
animal and vegetable substances when mi.xeil with substances containing potash
and kept at an even temi>erature in moist situations. On this principle artificial
nitre becls are made, from which large quantities of nitre are obtained, in France,
(Jermaiiy, Sweden. Hungary, etc. Saltpetre obtained from any of these sources
may be separated from the greater part of the foreign salts and earthy matter by
lixiviation with wood ashes and evaporation. The nitrous earth of India yields
about one-fifth of its weight of nitre ; that of the nitre caves, from one to ton
pounds of nitre to the bushel. The best artificial nitre bed? afford annually about
a quarter of a pound of nitre to a bushel of earth. Saltpetre, for the manufacture
of gunpowder, is chiefly obtained from India, whence it is imported in a cryst-al-
iaed state, called crude taltpetre containing generally from 15 to lb per cent, of
foreign salts, earths, and water.
TKST OK cm DE S.il-TPKTRE.
Crude saltpetre was formerly tested by washing it with water saturated with
saltpetre, which dissolved the other soluble foreign 6alI^' without ilissolving any of
the saltpetre itself; the loss in weight by washing was taken as the weight of the
impurities contained. This process was found to occasion serious error, from the
fact that when water saturated with saltpetre has dissolved a portion of sea salt, it
acquires the property of dissolving an additional amount of saltpetre ; besides,
this mode of testing fails when there is present — as there is almost always — the
chloride of potassium. The process of testing now used in this country, as well
as in Knglaud and India, is that of analysis. The chlorides that the crude salt-
petre contains are precipitated in the form of the chloride of silver by adding the
nitrate of silver to the solution of a given weight of the sample to be tested. The
sulphates are precipitated in the form of the sulphate of baryta by adding the
nitrate of baryta to the solution of a given weight of the sample : the amount of
these impurities can now be calculated.
UEFI.VING SALTPETRE.
The purity of saltpetre used in making gunpowder i? of the greatest importance,
not only on account of the quality of the powder, but more particularly a« dimia-
ishing the chances of explosion in the powder mills.
Wash the crude saltpetre in a large shallow pan with about 40 per cent, of cold
water, stirring it well with rakes. At the end of 12 hours, withdraw the water,
which takes away with it a portion of the chlorides. To free the saltpetre from
•arthy matters and the chloride of sodium, dissolve it by means of heat, in the
TEST OF SALTPETRE. 225'
least possible anvmiit of water, in a large copper kettle. When ft is entirely dis-
solvta, clarify the liquid by pouring in the solution of glue in the proportion, of
1-lOth per cent, of glue dissolved in five times its weight of water. The glue is added
at two different times; and the liquid should be well stir?ed, and the scum removed
as it forms on the surface. When the scum has nearly ceased forming, check the
boiling by adding cold water saturated with saltpetre, to precipitate the chloride of
sodium, which is removed as it falls to the bottom. When the scum has ceased
forming and the chloride of sodium is no longer precipitated, the liquid becomes
limpid, and it is permitted to remain several hours, keeping up sufficient beat to
prevent it from crystalizing in the kettle.
Remove the liquid gently, while at a temperature of about 230°, to the crystaliz-
ing pans, and stir it continually with wooden scrai)ers to prevent tho formation of
large crystals. The scrapers in large establishments are moved by machinery.
Draw the saltpetre, as it forms, to the sides of the paas, and when the liquid falls
to a temperature of about 70" draw it off into other vessels; it will then have
given up nearly all its salti>etrc. Take the saltpetru from th€ crystalizing. pans to.
the washitig ttouglw, and wash it twice from the rose of a watering pot with 50 per
cent, of cold water saturated with pure saltpeire, the water being permitted to
remain on the salt each time about two hours, and then drawn off: sprinkl&it with
50 per cent, of pure water, which merely drains through and is carried off.
The saltpetre, after remaining in the washing troughs three or four days, i.<=
taken to the drying reservoirs, where it is dried, and stirred from time to time with
wooden shovels. It is then passed through a brass %ieve, to separate any small
lumps or foreign particles, and is ready for packing. It is now like fine sand, and
as white as snow.
A 100-lbs. powder cask will hold about 132 lbs. of saltpetre. The scum, mother-
water, washings, etc.,. are collected, and the saltpetre extracted from them.
TEST 0-r REFINED SALTPETRE.
In order to be used in the manufacture of gunpowder, saltpetre should not con-
tain more than l-3000th of chlorides. To test this, dissolve 200 grains of saltpetre
in the least possible quantity (say 1,000 grains) of tepid distilled water; pour on it
20 grains of a solution of nitrate of silver containing 10 grains of the mitrate to
1,033 grains of water, that being the quantity required to decompose 200-3000ths
of a grain of muriate of soda; filter the liquid, and divide it into two portions: to
one portion add a few drops of the solution of nitrate of silver; if it remain clear,
the saltpetre does not contain more than l-3000th of muriate of soda; to the other
portion add a small quantity of solution of muriate of soda; if it become clouded,
the saltpetre contains less than l-3000th. By using the test-liquor in very small
quantities, the exact proportion of muriate of soda may be ascertained. The salt-
petre used in our best powder does not contain more than 1-lSOOOth of chlorides ;
and that used in the best sporting powder is refined a second time,, and contains
not more than l-60U00th part.

Charcoal.
(Tor gpncrni remnrkfi on charcoal, see Chapter X.)
or fho three cuinpoBcnt materials of gunpowder, the charcoal has the gp-ntcpi
elTocl iippn it!< qualify^ "''^•Sf? •» "'« great difference in it, due to the kind of wood
from wljich it is madb, and to the mode of its preparation. Light, friable and
porouH charcoal, which h>irn» rapidly and leaves the iciist anhes, is the beft adapted
for milking gunpowder. Charcoal from willow and black alder — chiefly the former —
obtained by liislillation in cast-iron cylinders, is used for powder for the military
service.
The wood is cut in the y)iring, when the sap is running freely. Branches arc
selected of three In four year's growth, not more than thrce-f|uart«rs of un inch in
dinniVler, ptrippod of its bark as soon as cut, and piled in dry and airy places.
The larger l>ranches are split lengthwise. All dead wood is rejected.
The dried wood is put in ujiright cast-iron cylinders, which are then closely
luted. The heat is applied to the outside of the cylinder, and care is taken to
prevent them from getting too hot. The gaseous and li()uid [iroducts escape by an
opening near one end. The progress of distillation is judged of by the color of the
flanc and smoke, and ^om^imcs by tett »ttcke which are introduced through tubes
prepared for the purpose. When the distillation is complete, the charcoal it
reuioved into sheet -iron tubs.
About 35 per cent, of brown coal is produced, by this process, to 100 parts of
dried wood.
Charcoal should be made only as it is required for immediate use, as it absorbs
moisture reailily from the air.
Wheu freshly prepared, it absorbs and condenses gaaes: it heats and, if in a heap
of 30 lbs. or more, takes fire spontanconsly.
The specific gravity of freshly-burned charcoal is about .380 ; when triturated in
a moist state for a long time under heavy rollers, its specific gravity Le increased to
1.100 and 1.400.
Sulphur.
Sulphur is found i» abundance, in the native state, in the neighborhood of vol-
canoes, mixed merely with earthy matters. It may also be obtained from the
sulphurets of iron ond copper, and from other sources, but is not so jiure in this
case as the volcanic sulphur. The specific gravity of native sulphur is 2.072 : that
of sulphur which has be«n fused. 1.99 — which is still further diminished by tritura-
tion. Sulphur melts at i'M° into a transparent and nearly colorless liquid which it
Hn-htcr than the solid sulphur. As tkc temperature is increased, the sulphar
beciancs more yellow and loss fluid : ot 482° it is of a dark brown color, and ao
thick a* to flow with difficulty. From .'■)00° to its boiling point, 7S8°, it IweoMM
more flaid. 6ulpfaar takes fire at a temperature of bHO°, and bums wit* a Mil
blue flame and eufibcating fumes. It is soluble in oiJ of turpentine, and inaolaUa
in w.itcr and alcohoL
MANUFACTURE OF GUXTOWDER. 22t
The supply of sulphur for this country i? lirouglit principally from Sicily, in the
crude state. It contains about 8 per cent, of earthy matter.
It is refined by distilling it in cast-iron retorts, and collecting the vapors in a
large chamber, where they are condensed. The temperature of this chamber is kept
at about 248°, and the liquiil sulphur is drawn off, through iron pipe? iu the side of
the chamber, into wooden moulds.
If the temperature of the cliamber be kept as low as 180°, the vapors are con-
densed in a light dust, called flowers of sulphur : in this state the sulphur always
contains sulphurous and sulphuric a<;ids.
Pure sulphur should bo of a beautiful citmn yellow color, slightl}' transparent,
should show no acid reaction on test pajtcr, and should burn without any residuum,
Sulphur may be refined, but not so thoroughly, by being melted, skimmed and
decanted. •
Manufacture of Gunpowder.
The buildings in which the different operations arc carried on are separated from
each other, and protected by trees or traverses as far as practicable.
There is great diversity in the mauipulations of manufacture, not only in different
countries, but even in different powder mills of the same country — each having
some particular mode of its own, which is preferred to the rest. The principal
operations consist in pulverizing the materials ver}' finely, thoroughly incorporating
them, pressing them into a cake, reducing the cake into grains, glazing the grains,
drying and dusting the powder.
Pulverizing. — The saltpetre is usually pulverized sufficiently when it comes from
the refinery. The charcoal is placed in large cast-iron barrels with twice its weight
of bronze balls. The barrel has several ledges on the interior, and is made to
revolve from 20 to '.^5 times in a minute. It is pulverized in '2 or 3 hours. The
sulphur is placed in barrels made of thick leather stretched over a wooden frame,
with twice its weight of bronze balls from .3 to .■) inch in diameter, and the barrel
made to revolve about 20 times per minute.
The sulphur is pulverized in four to eight hours.
Pnqtortions of materials. — All powder for the military service must be composed
of the following proportions by weight, viz:
76 parts of saltpetre, 14 of charcoal, and 10 of suliilmr:
or, 75 parts " 15 " 10 "
Incorporating. — The ingredients having been weighed out in tlic proportions
above given, the charcoal and sulphur are put together in a rolling barrel similar
to that in which the sulphur is pulverized, and rolled for one hour. The saltpetre
is then added, and rolled for three hours longer. In some mills this operation is
omitted. It is now taken to the cylinder, or rol/iii;/ mill. This consists of two
cast-iron cylinders rolling round a horizontal axis in a circular trough ul' about
9 iteet diameter, with a cast-iron bottom. The cylinders are G feet in diameler, IS
inches thick on the face, and weigh about 8 tons each. They are followed by a
wooden scrai)er, which keeps the composition in the centre of the trough.
228 ORDNANCE MANUAL.
A cbnrpe of 75 lbs. in some mill", and 150 His. in others, is then spread in the
trough <>f the rolling mill, and raoisteiud witli 2 to 3 per cent, of water, aceordinjj
to the hy;.'roinctric state of the atmos]iluTC.
It is rolled slowly at first, and afterward from 8 to 10 revolutions of the roller
per minute-, for 1 hour for 50 lbs. and .3 hours for 150 lbs. of composition. A little
water is adiled, as the process advances, if the composition pets very dry — which in
judged of by its color.
When the materials are thoroughly incorporated, tlu- cake is of a uniform, lively,
brownish red color. In this stale it is called mill cukr.
The quality of the power depends much on the thorough incorporation of the
materials, and burns more rapidly as this operation is more thoroughly performed.
The mill cake is next taken to ^he press house, to be pressed into a hard cake.
Pfeisinij. — Tlie mill cake is sjirinkled with about 3 per cent, of water, and
arranged in a series of layers about '2 inches thick, separated by brass jdates. \
powerful preseurc is brought to bear on the layers, which are subject t<> the ma.xi-
nuini pressure for about 10 to 15 minutes, when it is removed. Koch layer is thus
formed into a hard cake about an inch thick.
(irantilaiiiig. — The cake is broken into pieces by means of bronse toothed roller^
revolving in opposite directions, their a.\es being parallel and the distance between
them regulated as required. I'lnted rollers are sometimes used. The pieces are
passed through a succession of rollers, each series being closer together, by which
the pieces are broken into others still smaller, which pass over a sieve to another
roller, the small grains passing through the sieve into a receiver below, until the
whole is reduceil to the required size. The various sized grains are separated by
the sieves between the different rollers.
Glazing. — Several hundred pounds of the grained powder, containing from 3 to 4
per cent, of water, are placed in the glazing barrel, which is made to revolve from
9 to 10 times per minute, and in some mills from 25 to 30 times per minute.
Usually from 10 to 12 hours are required to give the required glazing. In thii"
operation the sharp angles are broken off, therebj- diminishing the dust produced
in transportation, and the surface of the grain receives a bright polish.
Dri/ing. — The powder is spread out on sheets stretched upon frames in a rooui
raised to a temperature of 140° to 160° by steam pipes or by a furnace. The tejnper-
ature should be raised gradually, and should not exceed 160°, ventilation being
kept up.
Dusting. — The powder is finally sifted through fine sieves, to remove all dust and
fine grains. The dust obtained in this and previous operations may be worked
over to make other powders.
Packing.
Government powder is packed in barrels of lOfl lbs. each. Powder barrels are
made of well-seasoned white oak, and hooped with hickor)- or cedar hoops, which
should be deprived of their bark : the cedar is not so liable as hickory or white o«k

to be attacked by worms, and it should, tberefoi-c, be used in preference; or llic
hoops may be prepared by immersion in a solution of corrosive sublimate. Tlie
hoops should cover two-thirds of the barrel. Instead of a bung on the side, a
screw-hole 1.5 inch in diameter is made in the head of the barrel, for mortar and
musket powder: it is closed by a wood screw with an octagonal head which must
not project beyond the ends of the staves; under the head of the screw is a washer
of thin leather steeped in a solution of beeswax in spirits of turpentine. Tins
screw-plug renders it unnecessary to take out the head of the barrel, and the l[i>ops
may, therefore, bo secured with copper nails; for transportation, a piece of doih
should be glued over the head of the plug. Some barrels have been made with 6
copper hoops, and others with 4 copper and 8 or 10 cedar hoops : the copper hoops
are 1 inch wide and J of an inch thick, fastened with 2 rivets, and nailed each with
3 copper nails O.Ci2r) inch long. Average weight of a hoop, 2J lbs.
Powder barrels made of strong sheet-iron, corrugated, the heads put in by folding
tlicm over with the metal forming the body, have been made, and are now on trinl,
with prospects of their answering a good purpo.«e.
It has been found that lining powder barrels with india-rubber cloth has an
injurious effect on the powder, in consequence of the affinity of the caoutchouc for
sulphur.

The barrels have generally I'i hoops, 14 to IG staves, and 2 or 3 pieces in each
head. The above dimensions are calculated so that with 100 lbs. of powder there
shall be a vacant space in the barrel, allowing the powder tp shake, in order to
prevent its caking. The barrel would contain about 120 lbs. of powder settled by
shaking.
Round towdeu, for immediate use, may be made in an expeditious manner, as
follows : Fix a powder barrel on a shaft passing through its two heads, the barrel
having ledges on the inside ; to prevent leakage, cover it with close canvas glued
<in, and put the hoops over the canvas. Put into the barrel 10 lbs. of sulphur in
lumps, and 1.5 lbs. of charcoal, with 60 lbs. of zinc balls, or of small shot (down to
No. 4, 0.014 inch in diameter nearly). Turn it by hand, or otherwise, 30 revolutions
in a minute. To 10 lbs. of this mixture thus pulverized add 30 lbs. of saltpetre,
and work it two hours with the balls; water the 40 lbs. of composition with 2

Sift the grains and dry the ]>owder as u.-ual : that which is too fine or too coarse
is returned to the pulverizing barrel.
Thi.< powder is round. an<l the grain is sufficiently hard on the surface; but the
interior is soft, which makes it unfit for kee])ing, and may cause it to burn slowly.
This defect may be remedied by making the grains at first very small, and by roll-
ing Ibcm on a sheet or in a barrel, watering them from time to time, anil adding
the pulverized composition in small portions ; iu this way. the grains will be formed
by successive layers; they are then separated according to size, glazed, and dried.
It aii])ears from experiments that the simple incorjioration of the materials makes
a powder which gives nearly as high ranges with field-pieces as grained powder;
the ineorpiirated dust from the rolliug barrel may therefore be used in case of neces-
sity. (Junjiowdcr burns at the temperature of 57.0° to fii)0° Fahrenheit.
Inspection and Proof of Powder.
Uefnre powder for the military service is received from the manufacturer, it is
inspected and proved. For this purpose, at least 50 barrels are thoroughly mixed
together. One liarrel of this is provtd by firing three rounds from a musket, with
service charge, if it be musket p<iwder ; if cannon or mammoth powder, from an
8-inch C(dumbiad, with 10 lbs. and a solid shot of H.j lbs. weight and 7.88 inches iu
diameter; if it be mortar powder, from an 8-inch mortar, with 1.25 lb. and a shell
7.88 inches in diameter, weighing 47. 0 lbs. The general character of the grain, and
il« freedom from dust, are noted.
(jkxeuai. yrAi.iTiKs. — liunpowder should be of an even sized grain, angular and
irregular in form, without sharp comers, and very hard. When new, it should
leave no trace of dust when poured on the back of the hand, and when flashed in,
quantities of IU grains on a copper plate, it should leave no bead or foulness. It
should give the required initial velocity to the ball, and not more than the maxi-
mum pressure on the guu, and should absorb but little moisture from the air.
SuK OK UHA1X. — The size of the grain is tested by standard sieves made of sbevt-

Jfuiikct powder.— in ODC should pass through sieve No. 1 ; all tlirough No. 2.
Cannon powder. — None should pass through sixive No. 4; idll through No. 5.
Gravimetric density. — Is the weight of a given measured quantity. It is
usually expressed by the weight of a cubic foot in ounces.
Tliis cannot be relied upon for the true density when accuracj' is desired, as the
shape of the grain may make the denser po*dcr seem the lighter.
Specific Gravity. — The specific gravity of gunpowder piust be not less than
1.75. It is important that it should be determined with accuracy. Alcohol and
water saturated with saltpetre have been used for this pwrpose; but they do not
furnish accurate results. Mercury, only, is to be relied upon. ,
Mercury Densimeter. — This apparatus was invented by Colonel Mallet, of the
French army, and M. Bianchi, and consists of an open vessel containing mercury,
a frame supporting a glass globe communicating by a tube with the mercury in the
open vessel, and joined at top to a graduated glass tube, which communicates by a
flexible tube with an ordinary air pump. Stop-cocks are inserted in the tubes
above and below the glass globe, and a diaphragm of chamois-skin is placed over
the orifice at the bottom of the globe, and one of wire cloth over the upper orifice.
The operation consists as follows: Fill the globe with mercury, to any mark of
the graduated tube, by means of the air-pump ; close the stop-cocks ; detach the
globe, full of mercury, and weigh it; empty and clean the globe; introduce into it
a given weight of gunpowder; attach the globe to the tubes ; exhaust the air till
the mercury fills the globe and rises to the same height as before; shut the stop-
cocks ; take oflf the globe and weigh it as before. If we represent by a the weight
of the powder in the globe, by P the weight of the globe full of mercury, by J" the
weight of the globe containing the powder and mercury, and by D the specific
gravity of the mercury, the specific gravitj' of the gunpowder will be expressed by
a D
the formula d = — ■
P—P'+a.
A mean of two or three results will give the true specific gravity.
The density of some samples of powder has been brought up to 1.831.
Initial velocity. — The initial velocity is determined by means of the Ballistic
Pendulum, or by Captain Benton's Electro-Ballistic Pendulum. For the method
of using this machine, see page 237.
Musket powder should give an initial velocity of not less than feet.
Cannon powder should give an initial velocity of not less than feet.
Strain upon the gun. — This is determined by Captain Rodman's Pressure
Piston. For the method of using this instrument, see page 238.
Cannon powder should not give a greater pressure than pounds on the square
inch.
Hyguometbic qualities. — If the powder bo made of pure materials and have
the required density, its hygroraetric quality follows as a matter of course. It may
be determined by exposing the powder to air saturated with moisture. For this
purpose, samples of about 1,500 grains weight may be' placed in a shallow tin pan, 9

inches by 6 inches, eet in a tub the bottom of which i? covered with water. The
pan of powder should be placed about one inch above the ."urfacc of the water, and
the tub covered over. In this manner any sample of powder may bo compared with
another of knows good quality. Good powder, made of pure materials, will not
absorb more than 2J per cent, of moisture in 24 hours.

ber of >;rains in 100 grs.. whether hard or soft, round or angular, of uniform or
irregular cize, whether free from dust or not: the initial velocities obtained in each
fire: the amount of moisture absorbed: and, finally, the height of the barometer
and hygrometer at the time of proof.
Marks ok the barrels. — Each barrel is marked on both heads (in white oil-
colors, tl»€ head painted black) with the number of the barrel, the name of the
Manufacturer, year of fabrication, and the kind of powder — cannon, mortnr or
m««A-W— the mean initial velocity and tbe pressure per square inch on the prcssur*
piston. Kaeh time the powder is proved, the initial Telocity is marked below the
former proofs, and the date of the trial opposite it.
Analysis of Gunpowder.
Whatever may be the mode of proof adopted, it is essential, in judging of the
qualities of gunpowder, to know the mode of fabrication and tb« proportions and
degree of purity of the materials. Tbe latter point m.iy be asoertained by analysis.
* In the first place, determine the quantity of water that the powder contains, by
subjecting it to a temperature of 212=", in a stove er in a tube with a current of
warm air passing over it, until it na longer loses in weight. The difference in
weight, iHifore and after drying, giv^s the amount of moisture contained in tho
powder.
To (Icteroiin, the quoMtity of Saltpetre— In a vessel of tinned copper, like a com-
mon coffee-pot. dissolve 1.000 grains «f powder, well dried before weighing, in 2,000
grains of distilled water, and heat it until it boils; let it stand a moment, and then
.decant it on a piece of filtering paper, doubled exactly in the middle ; repeat this
operation four times; at the fourth time, instead of decanting, pour the whole con-
tents of the vessel on the filter; drain the filter, and wash it several times with
2,000 grains of water heated in the vessel, using in all these operations 10,000
grains of water. After passing through the filters, this water contains in solution
all the saltpetre, the quantity of which is ascertained by evaporating to dryneis.
Dry the double filter with the mixture of coal and sulphur, and take the weight of
this composition by ut^ing the exterior filter to ascerUin the weight of that on
which the composition remains: this weight serves to verify that of the saltpetre
and to estimate the loss in the process.

out, to the action of a boiling solution of the sulphide of potassium or sodium,
which dissolves the sulphur aud leaves the charcoal, the weight of which may bo
easily determined.
It is important that the sulphides of potassium and sodium used in dissolving the
sulpliur should contain no free potassa or soda; for each of these alkalies would
dissolve a part of the carbon — particularly of the brown coal.
Tiic sulphide of carbon also dissolves the sulphur contained in powder, and may
be used to determine the weight of charcoal which it contains.
The charcoal, separated from the saltpetre and sulphur, is dried with care and
weighed, and should then be submitted to analysis in an apparatus used for burning
organic matters. The composition of the charcoal may be judged of by comparing
it with the results obtained in the analysis of charcoal of known quality used in
the manufacture of powder.
To determine the quantity of Sulphur directly. — Mix and beat in a mortar 10 grains
of dry powder, 10 of subcarbonate of potash, 10 of saltpetre, and 40 of chloride of
sodium ; put this mixture in a vessel (capsule) of platinum or glass, on live coals,
and, when the combination of the materials is completed and the mass is white, dis-
solve it in distilled water, and saturate the solution with nitric acid; decompose the
sulphate which has been formed, by adding a solution of chloride of barium, in
which the exact proportions of the water and the chloride are known. According
to the atomic proportions, the quantity of sulphur will bo to that of the chloride of
barium used as 20.12 to 152.44.
Restoring Unserviceable Poivder. ♦
When powder has been damaged by being stored in damp places, it loses its
.strength, and requires to be worked over. If the quantity of moisture absorbed do
not exceed 7 per cent., it is suflBcicnt to dry it to restore it for service. This is done
by exposing it to the sun.
When powder has absorbed more than 7 per cent, of water, it is sent to the powder
mills to be worked over.
When it has been damaged with salt water, or become mixed with foreign matters
which cannot be separated by sifting, the saltpetre is dissolved out from the other
materials and collected by evaporation.
Preservation, Storage, and Transportation.
In the powder magazines the barrels are generally placed on the sides, three tiers
high, or four tiers, if necessary. Small skids should be placed on the floor and
between the several tiers of barrels, in order to steady them, and chocks should bo
placed at intervals on the lower skid, to prevent the rolling of the barrels. The
powder should be separated according to its kind, the place and date of fabrication,
and the proof range. Fixed ammunition, especially for cannon, should not be put
in the same magazine with powder in barrels, if it can be avoided. FireWoAr
should never be stored in powder magazines.
234 ORDNANCE MANUAL.
In a room 13 or 14 feet wide, the barrels may be arranged in a double row in the
centre, two alleys 2J feet wide, and 2 gingle rows 0 to ]2 inches from the walls; iii
this way, the marks of each barrel may be seen, and any barrel can be easily
reached. In a room 12 feet wide, an equal number of barrels may be place<l in two
double rows, with a central alley of 3 feet, and J side alleys, next the walls, of about
10 inches each. There should be an unincumbered space of 6 or 8 feet at the door
or dciors of the magaz.ine.
Should it be necessary to jiile the barrels more than 1 tiers high, the upper tiers
should be supported by a frame resting on the floor: or the barrels may be placed
on their heads, with boards between the tiers.
.Besides being recorded in the magazine book, each i)arcel of powder should be
inscribed on a ticket attached to the pile, showing the entries and the issues.
For the jircscrvation of the powder and of the floors and lining of the magacine.
it is of the greatest im])ortance to preserve unob-slructed the circulation of air, under
the flooring as well as above. The magazine should be opened and aired in clear,
dry weather, irAen the tempcrutnre of the air outaiilr in loirvr than that iu»i<le thv muija-
zi'ne. It should not be opened in damp weather if it can be avoided. The ventilators
mnst be kept free; no shrubbery or trees should be allowed to grow so near as to
protect the building from the sun. The magazine yard should be paved and well
drained. The moisture of a magazine may be absorbed by chloride of lime sus-
pended iu an open box under the arch, and renewed from time to time; quicklime i*
dangerous, and should not be used.
The sentinel or guard at a magazine, when it is open, should have no fire-arms.
%nd every one who enters the magazine shoubl take ofl" his shoes, or put socks over
them ; no sword, or cane, or anything which might occasion sparks, should be
carried in. .
The windows should have inside shutters of cojiper-wire cloth. Fire should never
be kindled near the magazine for the repair of the roof or lightning-rod.
Barrels of jjowder should not be rolled for transportation : they should be carried
in hand-barrows, or slings made of rope or leather. In moving ])owder in, the mag9^
zine, a dolh or carpet should be spread: all implements used there should be of
wood or copper, and the barrels should never be repaired in the magazine. When it
is necessary to roll the powder for its better preservation and to prevent its caking,
this should be done, with a small quantity at a time, on boards, in the magazine
yard.
In the spring an inspection of the barrels should be made, and the hoops swept
with a brush wherever they can be got at, t-o remove the insects which deposit their
eggs at this season.
In wagons, barrels of powder must be packed in straw, secured in such a manner
as not to rub against each other, and the load covered with thick canvas.
In transportation by railroad, each barrel should be carefully boxed, and packed
so as to avoid all friction. The barrels should have a thick tarpaulin under them.
Tht cars should have springs similar to those of passenger cars.
FRENCH GUNPOWDKR. 235
English Gunpowder.
En;.;li.«h gunpovvtler — particularly their sporting powder — has long been noted for
its excellence, which is due to the care taken in selecting the best materials, and
the skill in combining them.
The woods used for making charcoal for gunpowder are the black dogwood, the
alder, and the Dutch white willow.
The coal is made bj' distillation in iron cylinders.
The ingredients arc separately reduced to an impalpable powder and passed
through silk cloths or bolting machines, then mi.xcd in a tub in charges of 42 lbs.
Oach, moistened with 2 or 3 pints of water, and incorporated in the cylinder mill
for 31 hours. The iron cylinders of the cylinder mill are 6 feet in diameter, weigh
a'ljout 3 tons each, and make about 8 revolutions in a minute in a circular iron
trough 7 feet in diameter. The incorporated material is subjected to a pressure of
76 tons to the square foot by means of a hydrostatic press, forming it into pressed
cake, which is broken by toothed rollers and formed into grains as above described.
It is glazed by rolling in a canvas cylinder, or large cask, making 40 revolutions
per minute, for U hours. It i.>< dried in a temperature of 140° to 150°, raised by
means of steam.
French Gunpowder.
The charcoal used by the French in making gunpowder is obtained bj' the com-
bustion of hlack ahhr in the open air in iron pots.
At the powder mills at Saint Chamas, the charcoal is made by distillation, effected
by passing a current of steam raised to a temperature of 540° to 600° into the ir'bn
cylinder containing the wood. Charcoal of an excellent quality is said to be
obtained in this way.
The materials are pulverized separately in leathern barrels by means of bronze
balls, and passed through a sieve to separate any foreign matters which may have
accidentally fallen in and might cause explosions in trituration.
, Two and three-fourths pounds of sulphur and the same of charcoal arc weighed
into a tub, moistened with 1^ quart of water, and mixed by hand for 5 minutes. It
is then transferred to the composition tray, 16^ lbs. of saltpetre are added, and the
tray taken to the pounding mill. The contents are emptied into a mortar and well
mixed with the hand for several minutes, without further addition of water.
A pounding mill contains usually from 16 to 24 mortars and pestles, arranged in
two parallel rows. The mortars are hollowed out of a piece of oals, with bottoms
made of a harder wood. The pestle is made of beech, and has on its lower end a
bronze shoe with its angles well rounded. It weighs about 88 lbs., and falls through
a height of 16 inches.
Each pestle gives in the beginning of the pounding from 30 to 40 blows per
minute, and after 10 minutes tlje number of blows is increased to 55 or 60 per
minute. The pounding is continued in this way for labours, including the stop-
pages for shifting the charges from one mortar to the next — which is done every
hour. These changes are made to mix the materials more thoroughly, and to break
236 ORDNANCE MANUAL.
the cakes which form at the bottom of the mortars. From the 6th to the 8tb
• bange, about 1 pint of water is added, or as much as may be necessary to give to
the composition from 7 to 8 per cent, of moisture. During the last 2 hours no
changes are made, so as not to interrui)t the formation of cake. The composition
is taken out of the mortar and dried from 1 to ,3 days, till it contains only about 6
per cent, of moisture. It is then taken to the house for granulation. This o]iera-
tion is jicrformcd in a barrel made by stretching two pieces of wire cloth over a
wooden frame. The pieces of wire cloth are placed one over the other — the outer
one fastened on by cords so as to be removed at pleasure, and rejdaced by another
of different sized meshes, the meshes being of the size of the grain required, i)f
musket or cannon powder. The distance between the wires of the inner cloth is
.28 inch. Halls of hard wood 2 inches in diameter, and 50 or fiO in number, are
jilaced, with the composition to be grained, in the barrel, which is made to revolve
about .SO times in a minute. The caked composition is broken by the balls, and,
passing through the wire cloths, falls into a tub beneath.
The contents of the tub are sifted in sieves which permit the small grains and
dust to pass through.
The powder is moderately glazed by rolling it, while still containing from 6 to 0
per cent, of moisture, in a barrel from 10 to 30 minutes — depending upon the kind
of powder and the amount of moisture it contains. It is so comlucted that the
jwwdcr, when dry, should have a gravimetric density of between h20 and 860
ounces.
The powder is theu passed through a standard sieve of parchment, and is dried
either in the open air, spread out on sheets, on tables, or in a drying room, spread
on sheets stretched over the top of boxes, into the lower part of which heated air is
forced and escapes by passing through the powder.
After dryiug, the powder is again sifted, to remove all dust.

ELECTRO-BALLISTIC PENDULUM. 237
Captain Benton's Electro-Ballistic Pendulum. (Plate 29.)
Detcnption. — This instrument consists of a vertical arc of brass graduated into
degrees *nd fifths, supported by a tripod with a thumb-screw at each foot. Levels
arc attached to the arc, that it may be kept in a vertical position. Two pendulums,
with their axis in the same lino passing through the centre, and perpendicular to
the plane of the arc, swing freely in front of and near to the arc. To the lower
extremity of each is attached a piece of soft iron. The bob of the outer pendulum
is adjustable. An electro magnet is attached to each end of the horizontal limb of
the are, and holds the pendulums horizontal, or at 90° from the 0° or lowest point
of the arc, when the soft iron of the pendulum is brought in contact with the mag-
net. The inner pendulum has at its lower extremity a movable point projecting
toward the arc, the head of which is struck by a blunt steel point on the outer
pendulum when the two pass each other, leaving a mark on the paper which is
clamped to the arc for that purpose. AVire conductors lead from the magnet to the
clamp-screws secured to the upright limb, where they are readily joined to the
wires leading to the batteries and targets.
The adjustments. — 1st. Level the instrument by means of the thumb-screws.
2d. See that the magnets are in such a position that each pendulum, when
brought up against them, is exactly 90° from the lowest point of the arc. The
magnets are held by clamp-screws to admit of this adjustment.
3d. Move the bob of the outer pendulum till the times of vibration of the two
are the same. This is done by connecting the wire of the magnet to the poles of
the battery, including the disjunctor in the circuit. Bring the two batteries to the
same strength. Break the currents by means of the disjunctor, and see if the two
pendulums meet exactly at the zero mark. The two batteries are known to be of
equal strength when the pendulums meet at the zero point, irrespective of the par-
ticular battery that works them.
The disjunctor is an instrument used to test the working of the batteries, and
tell when they are operating with equal activity. There are several forms of this
instrument, the essential point being to break the currents exactly at the same
time. It is so arranged that by setting the trigger the currents are formed, and by
pressing it they are broken. It should give the same point of meeting of the pen-
dulums in six or eight trials made in quick succession.
To use the pendulum. — Establish the wires as shown in Plate 29. Insert a piece
of drawing paper under the arc, and clamp it. Set the trigger of the disjunctor:
raise the pendulums against their magnets; press the trigger; if the point of meet-
ing is very near the 0°, set the trigger again : give the caution, " Ready;" raise the
pendulum, and "fire." Read o(f the angle, which must bo corrected, if the pendu-
lum on the trial did not meet at the 0°, by addinfj the angle between the 0° and
mark, if it be on the right, and by subtracting it if it bo on the left. The angle thus
corrected must be doubled for the time of passage of the projectile between the two
targets.
231? ORDNANCE MANUAL.
To dil<:rinine the iuitial rclocilt/.—het I be the length of the equivalent simple
jiondulum, and t the time of passing over any one degree beginning at an angle .r
from 0: then t= —
360 y 2glcos.x.
By substituting for x different values, we get the times of passing over the differ-
ent degrees, supposing the velocity to be uniform for the time of passing. In this
way a table is formed which should give the times for the different degrees and
tenths of degrees, and the sums of the times to each degree.
The value of / is determined by supporting the inner pendulum on the knife
edges, and noting the time required to make 500 or 1,000 vibrations. The length
of the c((uivalent simple pendulum is obtained from the relation l=^('V', t' being
the time of a single vibration as just determined, and /' being the length of the
8im])le second pendulum at the place of experiment.
The machine is placed on a solid foundation, about 100 yards from the cannon.
(5 rove's or Bunscn's batteries are best; Smcc's has been used with good results.
The power of the battery must be regulated according to the length and size of the
wire. Copper wire No. 10 is about the size required. If the wire be small and
long, the battery must be stronger.
The first target is placed about 20 feet from the muzzle of the gun, and the
second from 70 to 120, according to the velocity of the ]irojectile. The siie of the
target is no greater than is necessary to insure its being struck every shot, and the
distance between its wires is regulated in the same manner. For small arms a
much finer wire is used to form the target.
Captain Rodman's Pressure Piston. (Plate 21».)*
This iustrumenl is used to determine the pressure of the gas on the sides of the
bore of a gun. It consists of a hoiminy of wrought-iron, with a cylindrical nhank
at one end, chased with the threads of a screw, by which it is attached to the gun.
This shank has a cylindrical hole through its axis, .37 inch in diameter, into which
the piston fits tlosely. The head of the piston is terminated by a cutter, which is
forced bj' the explosion of the charge into a piece of wroughi-coppcr, leaving a cut
or indentation of greater or less length, according to the greater or less pressure on
the sides of the bore.
The cutter is made broad and thin, so as to make a loug cut compared with its
breadth and depth, that pressures which vary but slightly may be distinguished
more readily.
A strong «creic, at the opposite end of the housing to the shank, holds the disk of
copper on the cutter.
A ijns-check, made of thin copper, is set tip, by a die and punch, in the shape of a
hollow, shallow cup. It is placed against the lower end of the piston, the open eiui
toward the charge of powder. ,

LIGHTNING CONDUCTORS. 239'
A hole, .4 inch in diameter, is drilled into the bore of the gun at the seat of the
charge ; the outer part is counlcr-borcd and tapped so as to receive the housing.
To use the pfessiirc piston. — Clean and oil the piston and the hole in the housing
into which it works ; insert the piston in the housing ; put in the gas-check, press-
ing it down on the piston ; place a thin copper washer in the hole in the gun, and
screw the housing down firmly on it; place a disk of copper on the cutter; inter-
pose between this and the head of the screw a second disk, and press it down hard
on the cutter.
After each discharge, unscrew the housing, take out the gas-check, clean the hole
in the gun, the piston and the hole in which it works ; renew the gas-check as often
as required; see that the copper disk is pressed hard on the cutter.
The actual pressure in pounds is determined by placing the cutter in the dynamo-
meter, and applying a pressure until a cut is made of the same length in a similar
piece of copper.
LIGHTNING CONDUCTOES.
(Condensed from a "Circular Jleniorandum" issued by General Burgoync, In-
spector-General of Fortifications, British army, from the researches of Sir Wm.
Snow Harris, F. R. S., 1858.)
It appears to bo established —
That metal in a building, whether disposed in the form of a conductor or other-
wise, never attracts lightning.
That, provided the surfaces of metals are not interrupted by bodies possessing a
less conducting power, a building entirely of metal will be the safest of all, and
that such buildings require no further lightning conductors than connections with
the earth, over the masonry foundations on which they are often laid.
,That, with regard to a building of brick or stone, the object must be to establish
asufiScicnt number of lines of electrical conductors, extending from its most ele-
vated and prominent points to the ground, and further bring the building into a
condition similar to that of a metal building, by means of other conductors gen-
erally attached to more prominent lines of the building itself, such as the ridges,
angles and eaves.
There is no advantage, but the contrary, in endeavoring to insulate the con-
ductors from the building.
The best material for conductors is copper, either in tubes IJ to 2 inches
diameter, and .125 inch thick, or in plates 3.5 inches wide and .125 inch to .2
inch thick.
All metal surfaces, whether lead, copper, or iron, on ridges, roofs, gutters, or
coverings to doors or windows, to be connected by plates of copper with the con-
ducting system. Lead, on account of its low conducting power, cannot bo alto-
gether depended upon.
One or more solid copper rods, to project freely into the air, about 5 feet above
•Ho
ORDNANCE MANUAL.
fhf highest points of the building to which the main conductors are applied. Thi-
rumtnit of the rod to be pointed; but gold, gilt, or platinum tops are unnecessary.
The termination of the conductors below to l>c led into damp or porous soil, when
the building happens to stand upon it; but, when the soil is dry, two or three
trenches to be cut, radiating from the foot of the conductor, to a depth of IS
inches or 2 feet, and 30 feet in length, and either the conductor carried along
the bottom of the, trenches, or old iron chain laid in thera; carefully connected
with the foot of the conductor. The trenches to be then fillcil up to one loot in
depth with coal ashes, or other carbonaceous 8ub.stanco, and afterward with earth
or gravel.
If it be possible, in regulating the surface driunage, to lead a flow of water,
during the rain which generally accompanies thunder-storm.", oyer the sites of the
trenches, it will be an additional precaution.
Tanks arc ui«;les.<, except where the water flows freely into them fmm th« sur-
rounding soil ; and even then the}* arc .><uperUuous us appendages lo the conductors.
The conductors for a brick or stone magazine with slate roof should consist of a
sheet-copper strip 4 inches wide and .125 inch thick, covering the ridge and
securely fixed to it by wrought-coppcr nails. At each end of the ridge a solid
copper rod, .0 inch in diameter, is fixed to the conductor on the rid);c, and projects
about 6 feet above the highest point (jf the building : its upper end i» pointed.
Copjier strips, 3 inches wide, or copper tubes, 1 inch in diameter, paw down the
augles of the hip, and are firmly secured to the copper eaves gutter.
The descending w^j^ pipes, made also of copper, anil fastened to the face of the
buildiug by copper boldfasts, arc connected at their lower end to the uodergronud
conductor b}- a piece of copper, 3 inches wide, wrapped around the lower end of
the water ]iipcs and riveted to the underground conductor.
The underground conductor runs out from the building 4 feet, and then branchen
into two parts, each 8 feet long, 2 inches wi<le, and .12.') inch thick. These conduc-
tors are about 2.5 feet from the surface of the ground at the lower end, and are
covered with coal ashes and earth.
The copper shcathings on the doors and windows are connected with the lower
end of the water pipes by flat copper strips, 2 inches wide, fixed to the water table
by copper nails driven into wood plugs about 10 feet apart.
AVhen tubular conductors cannot be bad of sufficient length in one piece, they,
are connected by a union joint, and strengthened by a small pipe or femiU, about
4 inches long, inside the tube, and riveted to each end.
Buildings which have the eaves gutters and down-pipes made of tin or sine
should have a main conductor communicating directly with the ground : it should
also be connected with the eaves gutter, and the down-pipe should connect by a
metallic communication with the ground, running out some distance from the
building.
In case of buildings situate on a dry or rocky soil, especial pains must be taken
to lay down old chains or other conductors in various directions, to a distance of 10
LIGHTNING CONDUCTORS. 2-il
to 15 yards, and from 1 foot to 1.5 foot below the surface of the ground; and, if
possible, lead a flow of rain over the surface of the ground about or near the con-
ductor. Let the conductor terminate in a large surface of moist earth whenever it
can be effected.
If copper be not used for conductors, zinc is the next best material of which they
can be made. If iron be used, it should be in the shape of galvanized wroun-ht-
iron pipe, not less than 2 inches in diameter, firmly screwed together in joints of
extra thickness. '
Copper tube, of a thickness of from .125 to .2 inch, is always to be preferred : it
has more than five times the capacity for conducting electricity that iron has, and
more than three times that of zinc.

Furnaces.
Two kinds of furnaces are used in a laboratory ; in tho first, the flame circulates
around both the bottom and sides of the kettle; in the second, it comes in contact
only with the bottom : the latter are used for compositions of which gunpowder forms
a part.
Furnaces are built of bricks. The kettle is of cast-iron, about 2 feet in diameter
at the top, having a rounded bottom and a flange about 4 inches wide around the
top, or else strong handles, to set it by. The bottom is 0.75 inch thick and the sides
0.5'inch. By setting it in an iron plate pierced with holes, encircling the bottom,
a furnace of tho first kind may be converted into one of the second kind by stopping
the holes.
Furnace for rcdncinri the oxide of lead, or dronx. — This furnace is built in the open
air, on a stone or brick foundation. It is composed of a cjiindcr of sheet-iron, 16
inches by 30 inches, lined with refractory clay from 2 to 3 inches thick.
The interior has tho form of an inverted frustum of a cone, terminating below in
a basin, the bottom of which is inclined toward a tap-hole. The firo is made in the
furnace, and the draught supplied by a bellows, tho nozzle of which enters at tho
top of the reservoir. Tho dross, and the charcoal intended for its reduction, are
thrown on the fire from the top of the furnace. The metal, as it is reduced, flows
into the basin, and escapes through the tap-hole into an iron vessel, and is cast into
bars or pigs as desired.
In the (ielil, furnaces maybe built with sods or sunk in the earth, if bricks cannot
be readily procured.
Fvrnace built n-ith «of^«.— Let the kettle rest on a trivet, the feet of which may
stand on iiny piece of Hat iron, such as the bottom of a shot canister or stand for
grape, tlic bottom of the kettle about 1 foot from the ground; build round it with
sods. Tho door of the furnace is 10 inches square; the flue of tho chimney, oppo-
site to the door, 6 inches square, and commencing about 6 inches from the ground ;

Fitriiiire milk in llir rnrth. — The edge of the kettle shouhl be about 1 inch above
the groMinl, and the bottom 12 to 15 inches above the hearth of the furnace; the
earth is dug down vertically 1 foot from the kettle for the front of the furnace, and
the door is cut out ten inches square. The earth is removed and sloped out, so as
to give accotis to the door; the flue is bored out on the opposite side with a crowbar:
it ctinimenccs 6 inches above the hearth and comes out of the ground 18 inches
from the furnace, whence it is carried horizontally about 13 feel.
In furnaces of the second kind mentioned above, the trivet may be omitted, and
the kettle may rest on the sod or earth for about 1 inch all round, and the earth
rammed in against the sides of the kettle.
Precautions against Accidents.
Avoid, a« much as possible, the use of iron in the construction of the buildings,
fixture.>i, tables, benches, boxes, etc., of the laboratory ; sink the heads of iron nails
■if u.-ied, and fill over them «i;h putty, or paste several thicknesses of pajier over
them. Hefore the men go to work, cover the floor with cariiets cir tarpaulins, which
are taken up carefully after the men leave, and curried al least .'0 yards from the
building, and there shaken thoroughly and swept. I>uring the work, have the
carpets frequently swept.
Place the stores in cloth bags in the windows exposed t<i the sun. Prevent persons
from entering with sabres, swords, or canes, etc., or with matches about their persons.
Direct all who work where there is powder to wear moccasins or socks, and to lake
them off when they leave. Direct the men not to drag their feet in walking.
Make the doors and windows to open and close easily, without friction ; keep them
open whenever the weather permits.
Never keep in the laboratory more powder than is necessary, and have the ammu-
nition and other work taken to the magazine as fast as it is finished.
Let powder barrels be carried in hand-barrows made with leather, or with slings
of rope or canvas, and the ammunition in boxes. Let everything that is to be
moved be lifted, and not dragged or rolled on the floor.
Never drive rockets, portfires, etc., or strap shot or shells, in a room where there
is any powder or composition, except that used at the time.
Loading and unloading shells, driving rockets, pulverizing materials, the prepa-
ration of compositions requiring the use of fire and in which the components of
gunpowder ent«r, ought to be done in all cases, when possible, in the open air or
under a tent, far from the laboratory and magazine.
Never enter the laboratory at night, unless it is indispensable, and then use a
close lantern, with a wax or oil light carefully trimmed. Allow no smoking of
tobacco near the laboratory.
MATERIALS. 245
In melting lead, be sure that it contains no moisture; put the pigs in carefully,
and do not use more than will fill the pot two-thirds full.
Use the same precautions iu melting fatty substances.
Applications for Burns.
Exclude the air by applying to the burn frenh lard ; or bathe the part burned,
and cover it with linen soaked in a mixture of 8 parts of sweet oil and 1 of harts-
horn, well beaten together.
MATERIALS.
Saltpetre.
For use in the laboratory, saltpetre should be freed from all foreign substances
arid be reduced to a fine powder, or else to very minute crystnls. It is best pulver-
ized in the rolling barrels at the powder mills; but it may be pulverized by hand in
the laboratory, as follows: Put into a rolUmj hnrrel 50 lbs. of 'dry refined saltpetre
and 100 lbs. of bronze balls; turn the barrel for two hours and a half, at 30 revolu-
tions a minute, striking it, at the same time, with a mallet, to prevent the saltpetre
from adhering to the sides. Separate the balls by means of a brass-wire screen,
and the foreign substances with a hair sieve.
Saltpetre may also be pulverized by pounding it in a brass mortar, or by solution,
as follows; Put 14 lbs. of refined nitre, with 5 pints of clear water, in a broad and
shallow copper pan, over a slow fire, and, as the nitre dissolves, skim off the impu-
rities; stir the solution with a wooden spatula until the water is all evaporated,
when the nitre will be very white and fine. Should it boil too much, the pan must
be lifted from the fire and set upon wet sand or earth, and the saltpetre should be
stirred until it dries, to prevent it from adhering to the pan.
Charcoal
Is the residuum of the incomplete combustion or of the distillation of wood. Its
composition and properties vary with the kind of wood from which it is made, and
with the mode of carbonization used.
It is as much more dense and compact as the wood from which it is mnde is
harder and of a closer texture; its density is nearly proportional to that of the
wood, and its combustibility seems to be as much greater as its density is less.
The best charcoal for fireworks is that which is most inflammable and which
leaves the least ashes, such as coals from black alder, willow, poplar, hazel tree,
hemp stalks, etc. Hard woods, generally, give coals containing more ashes than
light, soft ones; old trees more than young; dead trees more than living; in the
same tree, the bark more than the sap wood — next the trunk, the roots, and, least
of all, the branches.
In some cases, where long trains of fire are desired, charcoal from hard woods.
OUPNANCE MANUAL.
«nch as oak, nuiplo, or beech, is used. Charcoal for fireworks is be<<t made in cl'><ied
TesselH. Tlio "liffcrentlirocesBcs of carbonization are only more or lusa rapid disiil-
latioDS of the vcKctablo substance carried to a greater or less extent. The volatile
matters wliii-h are disengaged, and the fixed substances which remain, vary at each
moment, but in such a manner that the character of the former indicates that uf the
latter.
In a slow distillation by a jirostrc^isiv'c heat not exceeding .070°, bluish vapors are
8rst di)<er,gaged, then carbonic and acetic acids, cmpyrcumatic oil, and soot in dark
olouds burning with a red flame. Carbonic oxide replaces, by degrees, the carbonic
aoid, the .smoke becomes clearer, and the flame takes a viulct lint. Afterward,
earburelled hydrogen is disonga\;ed; the smoke becomes translucent; the Uamo
passes from a violet to a yellow, then to a more and more shining white. Finallj,
the smoke disapjtears, and the flame grows shorter and goes uuu
If the operation bo sto]>ped when the flame of the gus becomes violet, about 40
per cent, of charcoal will be obtained. If the operation bo continued till the (lame
becomes yellow, there will be had not more than 30 per cent, of coal. Finally, not
more than la per cent, will remain after the flame goes out. In all of these rases,
with slow diiitillutiiin the carbonization is uniform frum the surface to the interior
of each piece of wood, and requires a longer time in proportion as tho temperature
ia lower.
In a rapid di.stillalion with a very strong heat, the gaseous products are disen-
gaged simultaneously; the distillation on tho surface of a piece of wood is finished
before it is har<lly begun on tho interior. To obtain uniform results by thift mctbud,
the distillation must be protracted till from 15 to 2U per cent, of coal only is
obtained. liy the rapid distillation a part of the incombustible matter is carried
off, and the coal remaining contains less asbos. The carbonization in boilers, pota,
pits, or heaps, is nothing more than a rapid distillation.
Charcoal obtained by stojiping the carbonization when the violet flame appears
has a brown ch,)eolate shade; its fracture is bri^'ht and even: it is flexible, in thin
pieces; reduced to a powder, it has a greasj* feeling and a velvety appearance; it
bnrn.s with a yellowish blue flame, bright and without smoke: it gives out a heavy
sound when broken, and dissolves almost entirely in potassa. Heated in a close
vessel, it yields tar, pyroligueous acid, and 40 per cent, of gas. It is composed of
earbon 0.7:55, hydrogen 0.28S, and ashes 0.007.
Charcoal obtained from a protracted distillation, when only 1.0 per cent, is had,
from dry wood, has a bluish black color, is hard and coarse; it breaks easily, gives
ont a clear sound, burns without flame, and is with difficulty reduced to a powder :
it is then dry to the touch, and docs not easily form a cake by pressure : it if
insoluble in caustic potassa. It is composed of carbon .906, hydrogen, .076, and
ashes OIS.
AH ch:ircoals are embraced within the two preceding kinds, and approach more
or less one or the other. Coal which ha« not reached the brown chocolate shade
bams with smoke : it is called smokv coal : it is not yet charcoal. Charcoal

fire at about 460°. Black charcoal, highly calcined, takes fire quickly, but is
easily cxiinguished ; red charcoal is longer in taking fire, but it keeps fire and
burns up rapidly. This combustibility is as much greater as the charcoal is lighter.
Charcoal at a red heat decomposes water to combine with its oxygen. Its absolute
density is at least 1.5; the apparent density is very variable.
Charcoal does not become a conductor of heat and electricity unless it has been
highl3' calcined at a white heat.
It absorbs moisture rapidly from the atmosphere — particularly when in a state of
fine powder. When freshly prepared and pulverized, it absorbs and condenses
gases; it grows warm ; and, if in a mass of more than about 30 lbs., it takes fire
spontaneously. Black charcoal, highly calcined, may be set on fire, when in pieces,
by a strong blow, or by friction.
To make a comparison between charcoals as to their action in compositions, make
an intimate mixture of 5 parts of saltpetre and 1 of the ch.arcoal to bo tried, both well
pulverized; drive a fuze with the composition, or press it in a metal tube of about
one-quarter of an inch bore ; take its weight and height, and determine the time of
burning by a watch or pendulum. The rapidity of combustion, or the length of
composition which burns in a second, measures the combustibility of the charcoal.
Note also the weight of the residuum.
The rapidity of combustion is independent of the diameter of the tube and of the
materials of which it is made: it varies very little with the greater or less com-
pression of the composition, but varies much with the degree of trituration of the
materials: it is, therefore, important, in comparing different coals, to mix the com-
positions precisely in the same way.
SuLPnnn. — When melted sulphur is to be used, care must be taken that it does
not become thick — which t.akcs place at about 320°. It is pulverized by being
rolled four hours in a rolling barrel with twice its weight of balls, or by being
pounded in a mortar and sifted. Roll brimstone is used for melting, and flowers of
sulphur m.ay be used instead of roll sulphur pulverized, but is not so good.
GuNPOWDEU. — For compositions, gunpowder is mealed, cither by rolling it for two
hours with once and a half its weight of balls, or by beating it an equal length of
time in a leather bag, or by grinding it with a mnller on a mealing table.
Mealed powder, and pulverized saltpetre, charcoal and sulphur, are generally
obtained from the powder mills.
SuLPHURET OP ANTIMONY is a gray solid, with a fibrous texture, very fusible, very
Tolatile, and easily reduced to a powder. Density, 4.6"2.
It is found in the natural state, and can likewise bo prepared by melting in a
crucible equal parts, by weight, of antimony and sulphur pulverized and mixed. It
is purchased in the state of a powder. Its purity is tested by treating a small
sample (l-'iO grs.) with concentrated warm hydrochloric acid. The residuum which
is not dissolved ought not to exceed the sulphuret used, by 12 per cent.
Chi-oratb op potassa is a white salt, crystalizcd in white scales, anhydrous, not
altered by exposure to the air. Soluble in water: more in warm than in cold;
248 ORDNANCE MANUAL.
insoluble in alcohol. Density, 1.989. Fusiible at about 6()2° ; it is tlecoini>osfJ at
about 720° into oxypen and chloride of potassium.
Thif chU if one of the most energetic of oxidizinp bodies, because it jiarts with
its oxyf^on readily, of which it contains a great quantity (..■191.') of its weight).
Thrown on burning coals, it melts quickly. It ex]>lodes by simple contact with
Bulphuric acid: mixed with a combustible body, the mixture may be exploded by
friction or by a blow. It should be purchasc<l crystaliz.ed, and should not contain
more than one-lhousandth of its weight of chloride of sodium or potassium. lU
purity is lesteil by means of the nitrate of silver dissidved in distillcl water — 73J
grs. in oiie-(|uartor of a pint. Dissolve 77 grs. of the chlorate in ;iOU grs. of warm
water, and let the solution get cold: the chlorate will be precipitated in crystals.
Add to the licpiiil about two drops of the solution of the nitrate of eilver. After
filtering, the liquid ought not to give a precipitate by the addition of more nitrate of
•ilrer.
Fi'LMiNATE oi" MKiiciitv is a white salt,crystali7.ed in fine, silky needles. Soluble
in water: more so in warm than in cold water.
The elements of this salt are held together so feebly that the least shock or
friction causes its decomposition with au ex]dogion. (For manner of making, see
page 285.)
Fi'LMiN'ATiNO Powi»KR8 are compositions that detonate with great force by
friction or by a blow. They are generally made of fulminate of mercury or s
mixture of chlorate of potassa and sulphurct of antimony. The preparation and
manipulation of these powders are very dangerous, and ought to be matie, with the
greatest precautions, far from the laboratory and magazines. The powder of
chlorate of potassa and sulphuret of antimony cannot be manipulated without
danger if it have not at least '20 per cent, of water with it. In this stale a blow or
friction explodes only the part struck or rubbed; the rest is dispersed without being
set on fire.
The fulminate of mercury, with 30 per cent, of water, cx]ilodes partially when
ground on marble with a wooden muller ; but the explosion is not communicated
to the rest. It should always be manipulated moistened with this amount uf
water.
Leap is a bluish white metal, bright, but tarnishes quickly in the air. Specific
gravity, when pure, II. ■lb : melts at 600°, and volatilizes at u red heat.
The purity of lead is judged of by its specific gravity. To determine this, aflor
ha> ing weighed the i)ig. suspend it with a wire in a vessel of water, so that it shall
be completely immersed, without touching the sides, and weigh it again. The
weight in the air, divided by the difference between the weight in air and water,
will give the specific gravity — which ought to be 11.35 for lead of commerce.
Lead melted in contact with air is soon covered by a coat of gray oxide, which
rapidly increases in thickness. The formation of this oxide, or dross, is prevented
by covering the lead with powdered charcoal or rosin.
To reduce tin oxide of lead. — Put in a kettle about 50 lbs. of lead, with 1-lOth of
MATERIALS. 249
its weight of powdered charcoal or grease; cover the kettle, and raise to a red heat;
stir the mass, and add {gradually more coal, as it assumes a yellow color, using in
all i of the weight of oxide; dip out the lead with an iron ladle, and pour it into
iron moulds or pans. After having obtained in this way two-thirds of the weight
of oxide, in lead, throw the dross into a tub of water, and wash it, to separate the
ashes and coal ; dry the remaining oxide and grains of lead, and put them in a
ladle with l-20th of their weight of rosin ; raise it to a red heat, set fire to the rosin,
shake the ladle, and pour off the lead. A further addition of rosin will produce
more lead; 1-1 4th of the weight of dross is generally used. Tallow may be used in
place of rosin.
AVhen the quantity of dross is considerable, it may be reduced, in a similar man-
ner, in a small cupola furnace.
Acetate op lead (Surjnr of Lead) is a white, efiBoreseent salt, of a sweetish
taste, soluble in three or four times its weight of cold water. Specific gravity,
2.345. It may be made by heating a mixture of litharge and vinegar. The solu-
tion being concentrated and set aside to cool, the salt crystalizes in white, brilliant
needles.
Plumbers' solder is an alloy of lead and tin, in the proportion of 2 parts of the
former to 1 of the latter.
Antimony {Rcgulufi of Antimony) is a grayish white metal, very brilliant, with a
highly lamellatcd structure. Specific gravity, 6.7; melting point, 809°. It is
easily reduced to powder, and by its combustion with sulphur produces a strong
light and heat, with a blue or white flame. Antimony is never found pure in the
shops ; that which is sold under the name of reffiiliis of aiilimony always contains a
little sulphuret of antimony, arsenic, and sometimes sulphuret of iron.
Copper is a red, brilliant metal, possessing great tenacity, ductility and mallea-
bility. Specific gravity, 8.9; fusible at about 1980°.
Copper, being but slightly acted on by saltpetre, is employed for powder
measures, utensils for refining saltpetre, etc. Copper vessels should not be exposed
to a great heat, or used for heating compositions containing sulphur, as the copper
would be rapidly oxidized.
In fireworks, copper filings are used to give reddish sparks and a greenish blue
flame.
Bronze is used in the laboratory for utensils and implements which receive
Wows, or act by percussion, and replaces steel and iron wherever there is danger of
an explosion from a blow or from friction.
Brass is an alloy of about 2 parts of copper and 1 of zinc. Brass wire is used
for ligatures, for screens and sieves.
Acetate of copper ( V< rdigris) is a green salt, used sometimes to make slow-
match, which burns with a strong coal and with a slightly green flame.
Zinc is a bluish white metal; usually brittle, and its fracture shows a crystalline
structure. Specific gravity, 6.9; melts at 680°, is volatilized at a red heat and takes
^ fire in the air, burning with a white flame. At 400° it is easily reduced to a pow-

TnoN. — Filings and thin chips give very brilliant ."sparks and stars, the effects of
which dijiciid on (he size of the particles used; the filin(;s must be made when
wantc'l, or be very enrcfully preserved from rust.
SnKKT-inoN. — Select the softest and most pliable. M'hen it is substituted for
tin, in strajtpin}; projectiles, it should be first annealed, by heating it to a dull red
heat, and letting it cool grailually under warm ashes, not exposed to the air.
Cast-iron. — Pulverized, it gives very large white sparks, in fireworks (Chinese
Are). Select the white cast-iron, or take the pieces of utensils with thin sides. To
pulverize it more easily, heat it to a red heift and throw it into cold water. \
Stkkl. — In fireworks, filings and small pieces give the most brilliant sparks.
Pai'kh. — Mniikct-cartridgf paper should bo homogeneous and without any trace
of stalks, well sized, even, pliable, with a good body without bt ing loo thick, free
from folds or rents.
The sheet, when moistened, ought to present a uniform hue, without spots or
marblings. Taken out of the water and suspended a moment by the extremiiic*
of the short sides, it ought not to tear from its own weight. The sheet crumpled
in the hand or pinched with the nails ought not to t«ar in the f<dd8, and when torn
the rent should be fibrous.
A strip of paper 4 inches wide ought not to break under a weight of 40 pounds,
in the direction of its least strength.
In testing the strength of pa]>er, the two ends are held >iy two vices of hard
wood. Each vice is comjiosed of 2 rectangular jaws, which can be brought against
each other and held firmly by means of screws, or bj- tenons on one jaw passing
through the other and keyed firmly to it. A strip of paper 4 inehes wide is cat
and iu.scrted in the vices, so that the length between them shall be exactly 12
inches. The jaws arc dosed tightly, and one vice is suspended from a fixed point
by means of a cord or hook, and to the other is made fast the pan of a bn!:ince.
It is loivdcd gradually, with care, until the paper gives way. The strij'-* r'lould
not be taken from the edges of the sheets only, but from all parts, and 'roui the
length and breadth successively, for in these two directions the strength is very
different.
Five sheets are generally Uikcn from each ream, in which only one sheet cai
have one-tenth less strength than that allowed. If this condition be not fnlfillod.
the ream is rejected.
Paper may be made by hand or by machine.
The other papers are tested in the same way, and should possess the same gen-
eral characteristics.

To prepare Pastes and Glue.
Flour Ptmir. — Sift the flour, and mix it with 8i times its weight of water ; heat
it geutly, stir it, and let it boil for three-quarters of an hour; when it I)ecome8
ropy, pour it into bowls, and pass it through a sieve before it is quite cold. The
flour yields 7 times its weight of paste. Time reejuired to make it, one hour and a
half. It is best made of rye flour.
Starch PiiMe. — Mix wheat starch with twice its weight of water: pour it grad-
ually into 6i times its weight of boiling water, and let it boil for ten miuutcs,
stirring it all the time; then i)roceed as before. Starch yields 8 times its weight of
paste. Time required, 1 Imur.
PaHtf for I'antrboard. — Mix the flour or starch with 12 times its weight of water:
this yields 9 times the weight of flour, and 11 times the weight of starch.
PoHte mixed trith (ilite. — The addition of 1-1 Oth of glue makes the paste fit for past-
ing sheets of parchment together, or for pasting jiapcr on wood. Dissolve the glue
separately, and pour it into the cold water with which the flour or starch is mixed.
Cliemc I'uHif is made of fresh white cheese ftOd quicklime. Pound the cheese in %
mortar with boiling water: let it stand, and decant it: repeat this operatinn three
or foUY times. Pound together 3 parts of tliis cheese thus prepared and 1 jjart of
quicklime, moistening it with pure water till the paste ro]ies like honey. Prepare
only a little at a time. It is used in pasting parchment and parchment paper.
These different kinds of paste should be used cold. A sujiply for not more than
2 or 3 days should be made at one time; but it may be preserved longer by adding
alum in the proportion of 1-lOth of the weight of flour. The depredations of rati
may be prevented by dissolving a like proportion of colocyuth in the water with
which the paste is made.
Ulur is dissolved in its own weight of boiling water A glue pot with a water
b&th should be used, to aroid burning the glue. Kemove the pot from the fire M
soon as the glue is entirely dissolved.
Trituration of Materials.
Materials intended for the preparation of fireworks are reduced to a powder by
rolling them in a leathern barrel with bronze balls ; or, if the barrel be not on hand,
leather sacks, or mortars and pestles, may be used, attaching the pestle to an elastic
rtd.
During the trituration with the barrel, strike the bars of the barrel from time to
time with a small mallet, to deta-h the materials which may adhere to the sides.
The materials taken from the barrel are first passed through a brass screen, to
separate the balls, and then through a sieve. For certain purposes, as for signal
rockets, the charcoal should not be an impalpable powder. The trituration is then
made in a leather sack.
The sack is filled and closed up: one man holds it by the mouth, lays it on an
even block, and turns it frequently, whilst another strikes it with a billet of wood.
BALL CARTRIDGES. 253
After five minutes, the charcoal is taken ont and passed over a silk screen, to get rid
of the dust: what remains is then separated into three numbers —
No. 1. That which passes through the screen No. 1 ;
No. 2. That which passes through the screen No. 2;
No. .3. That which passes through the screen No. 3.
AMMUNITION FOR SMALL ARMS.
There arc two kinds of cartridges used in service — the ball cartridge, made with
a single elongated ball, and the buckshot cartridge, made with fifteen buckshot.
Ball Cartridges*
Making balls. — Lead balls are made by compression, by means of machines for
that purpose. Balls thus made are more uniform in size and weight, smoother, more
solid, .and give more accurate results, than cast balls.
The lead is first east into round cylindrical bars, .58 and .6.3 inch in diameter for
the calibres .•'')8 and .69 inch respectively, and 21 inches long, and then rolled to .46
* and .56 inch in diameter for the same calibres respectively : length, 25 inches. These
bars are fed to the machine, which cuts off a part sufficient for one ball and transfers
it to a die, in which the ball is formed, with cavity and rings, the surplus metal being
forced out in a thin belt around the ball in the direction of its axis. The balls are
trimmed by hand, with a knife, and are then passed through a cylinder gauge of the
proper size.
A (lay's work. — One man can m.ike with the macliine .30,000 balls in ten hours,
the bars of lead being prepared for him. One man can cast \,-)0() bars in 10 hours,
and can trim and roll 2,000 bars in ten hours. A boy can trim and gauge 5,000 in
10 hours.
Bullet moulds are provided to cast l)alls, where the pressed balls cannot be had.
The mould is so constructed as to trim the balls by a single operation before they
are taken from the mould.
Buckshot are compressed by machines in a similar manner to balls. They are also
readily obtained from private shot works.
To GREASE THE BALLS. — Placc them on their bases on a tin frame capable of
holding about 50 balls, and immerse it in a melted mixture of 1 part of tallow and 8
of beeswax, kept warm, until the cylindrical part of the ball is covered. Remove
the frame, and let it stand until the grease hardens.
Three frames arc required for each boy.
TO CUT THE PAPER.
• WOUKMAN. — 1 cxitter.
Materials. — Paper and pencil.
Impleme.vts. — 1 cutting-board, 30 inches square; 1 iron rider, 33 inches long; 1
lever, 1 cord, 1 large knife, 1 sandstone, 1 trapezoid of hard wood or iron.
* A metUod of attaching the paper cartridge directly to the ball has recently been invented by
F. J. Gardner, iind is used in the Confederate Liiboriitoiy at Kidiniond.
254 ORDNANCE MANUAL.
Cut the paper first into strips of a width e'|ual to the Icnjrth of a trapcxoid, and
then into tnipezoids, using the pattern as a gui<ie.
The paper and ruler are kept from moving by means of a lever, one end of which
is fixed and the other is moved by the foot by means of a cord and treadle.
The knife is held in both hands.
From C to 8 rcam.s may be cut at a time in lliis way.
A cutting machine, like that used by bookbinders, facilitates the operation when
many hands arc employed.
When only a knife and ruler are used, about 12 sheets arc cut at a time.
TO MAKK TIIK CAUTItlDGK.
WoRKMKN. — 1 mnslcr, 10 boi/i.
Imi'I.kmknts /or each boy. — 2 Itoxen to ludd cylinders, 20 inches long, 8 inches
wide, and 4 inches high, in the clear, made of i-inch boards, without a cover: they
are placed on their sides, their backs ineliueJ against the partition in the middle
of the cartridgB table, the front resting ou clcuts nailed to the table ; 1 former,
eyliudricul, of hard woimI, of the same diameter as the ball, 6 tu 7 inches long, one
end pointed, almost as much as the ball, and marked with a shallow groove 4.0
inches from the end ; I aabot or frame, lacked to the table, to hold balls, placed at
the left hand of the boy; 1 »pool of thread, turning on a vertical spindle fixed in
the table near the balls ; I choking-ntriiKj, made of 4 or '> -carlridgc threads twisted
together, about St inches long, with a wooden toggle at ihc onJ — fastened to the
edge of the table, at the right hand of the boy; 1 knif^ bludr, \\ ineh long, hooked,
driven into the 'front of the table below and near the chcike-string.
To KOUM THK cvLi.NOEn. — Lay the trapezoids on the table with the side perpen-
dicular to the bases toward the workman, the broad end to the left.
Take the former in the right hand and lay it on a trapezoid, the groove in the
former against the right edge of the paper, bringing the pointed end J imh from
the broad end of the paper; envelop the former with the paper; then, with the
fingers of the left hand laid flat upon the paper, turn the former and roll all the
paper upon it : hold it with the left hand, and, wiib the ehoking-atring in the right,
take one turn around the cylinder at about J inch from the end; h<dd the former
firmly in the K-ft baud, and draw gently upon the chokiiig-string, pressing at the
same time with the left forefinger upon the projecting end of the eyliudcr, thus
folding it neatly down upon the end of the ball. Having choked the cylinder
close, carry it to the right side, and, with the thread in the right hand, take two
half-hitches firmly around the part that has been choked; cut the thread on the
knife blade, and press the choke in a cavity in the table; place the former, with a
cylinder ou it, on a second trapezoid ; put a ball over the end of t! c former; roll
the paper on the former and the ball; hold the cylinder in the left hand and choke
and tic it as just described for the inner cylinder; withdraw the former, pressing
the eyliudcr with the left band, and i)lacc it in the box.

AMMUNITION FOR FIELD AND MOUNTAIN SERVICE.*
The iiiiirimnition for field and mountain service consists of —
Shitl for tiie 6 and 12-pdr. guns.
HhfllH for t ho 12-jjdr. guns, an<l 12. 24, and 152-pdr. howit/.cr and mountain howitzer.
Sjilieriml-rttiie ulioi for the 6 and 12-pdr. guns, and 12, 21, and .32-pdr. howitzer
and mountain howitzer. '
('(iiiiKlrrii for the f) and 12-pdr. guns, au^^ 12, 2'1, and .'?2-|)dr. howitzer ami moun-
tain howitzer.
The projiclilo is attached by strajts of tin to a wooden »<il>ot. to whicli is also
fastened the vnytiiiiijc-bnij containing the charge, for the gunc, the 12-pdr. howitzer,
and the mountain howitzer, making to;^ether <t round of fixed nmmunition. The
oartrid;;c for the 24 and .'<2-])dr. howit/.cr.s is not attached to the sabot, but to a
tarlridijc-btock, and is separate from the projectile.
Cartridge-bags.
The cartridge-bag is a cylindrical bag with a circular bottom, made of merino or
nergo. The material should be composed entirely uf wool, free from any mixture
of thread or cotton, and of suflSeiently close texture to prevent the powder from
sifting through: that wiiich is twilled is preferred. Flannel is used when the other
Ulaterialc cannot be conveniently uhtained.
TO Ct'T THE CLOTH. k
Implicmknts. — 2 lablcH ; jinttcrnn, of hard, well-scasoncd wood, or of sheet-iron
or tin, for the rectangles and bottoms: shfari ; chalk or colored crnyont.
A marker and assistant spread out the cloth on the table in two thicknesses, and
make it fast at each end of the table on three or four hooks driven in the ends of
the tabic, or by means of weights, drawing it suflBciently to lake out the folds, and
uo more.
They murk out the rectangles and bottoms with the patterns and ruler, so dispos-
ing and c<imbiuing them as to cut the clotii to the licsl aJvaiitag"-.
The length of the rectangle (development of the tylindtr) should be taken in the
direction of the length of the stuff, as it does not stretch in that direction. The
Bolvagc, if there be any, ought to be at the mouth of the bag. The cutter takes
a piece thus marked to another table and cuts out the rectangles and bottoms with
a pair of .*liears. The l)ottoms may be cut out with a hollow punch of the proper size.
Skwing. — Marks for the seam are traced on the rectangles and bottoms, by mi'ans
of patterns of the proper size. The seam should be at least a half inch from the
edge. The bag is sewed with woollen yarn, with a backstitch, 12 to the inch. The
edges are turned down on the same side of the seam and basted, to prevent the
powder from sifting through; the edges of the bottom are basted down upon the
sides. Bags may be sewed advantageously by the sewing machine. Bags fur fixed
* The ammiwition for rifle guns is nut ^ct fully Uecideii uo, and is, tlicrefore, uButted.
SABOTS AND CARTRIDGE-BLOCKS. 259
ammunition are gewed to within .'5 inches of t'l • mouth for 12-pihs.; to within 2.75
inches for 6-pclrs. ; all others, up to the mouth. A bag is given as a model to .sew by.
Cartridge-hags, when filled, should pass through the small shot-guage of their
calibre; those used for patterns should he thus verified. The empty bags should
be measured by laying tiic bag, flattened cut, between two marks ou a table, show-
ing the width of the pattern-bag; a variation of 0.1 inch, greater or less, is allowed.
Reject those sewed with too Inrge stitches.
Bags for practice or for blank cartridges may be formed i>y sewing together two
rectangular pieces with semicircular ends; the cloth is marked, for cutting and
sewing, with stamps made of 1-inch boards of the dimensions of the cutting slamp,
with a strip of tin or copper fastoned to the edge of the board, and projecting about
i inch perpendicular to the side; another strip parallel to the first is inserted in a
groove i inch from it: the edges of these strips are made rough, to retain chalk or
paint used in marking. A handle is placed in the middle of the face opposite to
the marking strips. Width of cutting stamp for ]2-pdr., 7.0 inches; for 6-pdr., 6
inches. Length, including semicircular ends, for 12-pdr., 10.5 inches; for O-jxlr.,
8.5 inches.
Packing. — Cartridge-bags are preserved from mnths by being packed with
pounded camphor and black pepper, or dipped in water with arsenic dissolved in
it, or a solution of sulphate of copper, I lb. of sulphate to 26 lbs. of water. Oj^-
they may be sealed up, in bundles of 50, in cases made of cartridge paper, carefully
closed with strips of thin paper pasted over the seams. Each bundle is marked
with the number and kind of bags.
Tliey may be preserved from moisture bj' being enveloped in water-proof paper.
Sabots and Cartridge-blocks.
Subot» and Caitridge-hhukg are made of poplar, basswood, or othdir light, close
grained wood: it must be well seasoned, and should be clear of knots and splits.
The assistant saws the scantling to the proper length for a sabot, roughs it out,
and marks its centre.
The turner puts it in the lathe, and turns, first the exterior and grooves, and then
the cavity for the projectile.
The holes for the handles .are bored with a bit, and countersunk on the inside to
receive the kuot on the end of the cord. Distance between them for shells is 1.5
inch; for canisters, 2.3 inches. Length of cord for handles, for shells, 12 inches;
for canisters, 20 inches. Diameter of cord, .15 inch.
The cartridge-blocks and sabots for shot and spherical-case shot for guns have
one groove. Sabots for gun canisters and for the 12-pdr. howitzer or mountain
howitzer shells, spherical-case shot and canisters have two grooves. All the
grooves are .3 inch wide and .15 inch deep. They are .8 inch apart, from centre
to centre, for guns, and ,5 inch for howitzers. The corners and bottoms of the
grooves are slightly rounded.
260 ORDNANCE MANUAL.
The dimensions of finished sabots and Mocks are verified with appropriate
gauges. For dimensions, cee page 2()0.
A dny'» wurk. — One man can make 3j0 sabots for 6 or 12-pdr. gun,
or 300 " " field howitzers,
or 600 cartridge-blocks, small charge, tn
or 700 cartridge-blocks, large charge. -"^ik
Straps.
Straps are made of sheet-tin. For nhot there arc two straps crossing at riirht
angles, one passing through a slit in the middle of the other. For nhrlh there are
four straps factcncd to a ring of sheet-tin, picrce<l with 4 slits, thr<iugli wliicb the
ends of tiic straps are i^nssed and foldeil down on the under side.
The sheet of tin is first cut to a length equal to that of the stra]>s. and if the
straps are for shot, a line is drawn, dividing it into two e(|iial parts, to mark the
place for the slit. The straps are cut with circular shears. If such be not at band,
the width of the strap is marked on the sheet, is cut with tinners" shearc, and
straightened on a bench with a mallet.
The slits arc made with a cold-chi.-'el on a bluck of Icail, and a str«|» not slit is
passed through, and .^et flat by a blow of the hammer.
Ring Si.
liivijH arc cut from sheet-tin by means of two punches: the first having the
diameter of the exterior and the other that of the interior of the ring. The slits are
made with a cold-chisel, and the required concavit}' to fit the ball is given by ham-
mering on a block of lead having a concave surface. The ends of the straps are
passed through the slits, folded down, and set flat. Dimeiition* of rings: exterior
diameter, 3. 'J5 ; interior diameter, 1.70.
Strapping Shot and Shells.
Impi.kments. — 1 hrtich ; '2 pani, containing natU O.-O.*) inch long, with f-troug, flat
beads 0.2 inch diameter; buxt and barrels, for straps and sabots: 4 /mmmrr*, for
strapping; 1 common hnmmrr ; A piinrhn ; ahot-gawjet, of each calibre; 1 g'lH'jf for
each calibre. 0.04 inch greater than the largest shot-gauge, through which the shot
should pass aft*r it is strapped; tine or ragt, for wi[iing balls; 1 trheelbarrote ; 1
tarpaulin, if the shop have not a plank floor.
A helper knocks ofl" the scales from the balls with a hammer, cleans and dries the
interior of the shells, if requisite, wipes the balls, and gauges them both before and
after they are strapped.
The workman, sitting astride the bench, places the shot or shell in the cavity of
the sabot, the roughest part of the shot down, the fuie-hole of the shell tm top, ia
th« axis of the sabot. The ball should rest on the bottom of the cavity (it can b«
told from the sound, by striking on the bottom of the sabot with a hammer) ; if it da
SPHERICAL-CASE SHOT. 261
not, the sabot is rejected. The workman places the junction of the straps in the
axis of the sabot, or the ring concentric with the fuze-hole of the shell ; beginning
with the strap which is not slit, he forces the end of it into the groove of the sabot
with the back of the hammer, punches it, and nails it; he then draws the other end
tight, punches it, and nails it, in the same manner. He disposes the other strap
perpendicular to the first, nails it to the sabot as he did the first, cuts off the super-
fluous length, and with the hammer and side of the cold-chisel sets the straps in
close to the ball at the top of the sabot.
The sabots for 32 and 24-pounder field howitzers having no groove, each strap is
fastened by 1 nail on the side and 2 under the bottom of (he sabot.
A day's tnirk. — Two men can strap, in 10 hours, 130 shot, or Tf) shells, cutting the
tin from the sheet.
Thk boxkr mode. — Uore a hole, .2 inch in diameter, .\-'> inch deep, in the shot;
enlarge the hole at bottom. Take a copper rivet .2 inch diameter, hollow out the
end, leaving the length of the rivet .25 inch greater than the least thickness of the
sabot; bore a hole in the centre of the sabot for the rivet, with a countersink for the
head; place the shot in the sabot, the hole down; insert the rivet in the sabot,
making it enter the hole in the shot; strike the head of the rivet a blow with
a hammer to upset the end of the rivet and fasten the sabot.
Another mode. — If tin or sheet-iron cannot be procured, straps may be made of
ttroiig cauvtif, 1 inch wide, sewed at the point of crossing. The part of the ball
which is to be inserted in the sabot is dipped in glue; the straps are also glued to
the ball ; the ends are doubled into the groove and secured by 2 nails in each end.
Another method is to wrap round the ball a band of canvas 1 inch wide, one half of
which is glued to the ball, the other to the sabot; or the shot may be kept in place
by merely tying the cartridge-bag over the top of it.
Charging Shells.
Matertai.s. — Ri'fe or mttuket powder ; pliigx ; fuzes; chnlk.
Imi'Lkmk.nts. — 1/iiniiel; powder measure, to hold the required charges : 1 wooden
sfrai(/lil-edi/e ; lurcfe howl ; fuze-wrench.
The shells, having been properly cleaned, dried, tapped to receive the plug and
the fuze, and attached to the sabots, are placed in two rows. The workman fills the
measure with powder, strikes it level with the straight-edge, and pours it in the
shell ; the assistant holds the funnel, and marks the shell with chalk when filled, to
prevent mistakes. The assistant screws in the plug. The workman puts a little
white lead on the threads of the fuze, punches 4 or ii small holes in the tin disk, and
screws the fuze firmly into the shell, the assistnnt holding the shell to prevent it
from turning.
Spherical-case Shot.
The shot leaving been cleaned and inspeete<l. the upper part of the fuze-hole is
tapped to receive the fuze; the small hole is tapped to receive the plug.
20:i ORDNANCK MANUAL.
TO FILL THE SHKLI,.
Matkrials. — Sphcn'ral, leaden balls, calibre .59 inch; nnlphiir ; Unbred oil.
Utknsils. — 1 kettle ; 1 ladle ; 1 iron funnel, the neck chiiseil with the threads of
jt screw, to fit the smiill part of the fuze-hole.
F'li.LiNf) THK siiKLL. — Corcf the lead halls with linseed oil, and fill the shell with
them, pushinp (he upper halls aside with the fingers or .a A'wV, to get in as many aa
poBsihle. Warm the shell gently, and screw the neck of the funnel into the fu«o-
hole : jioiir in the niclted sulphur, filling the shell.
To MAKK THP, CHAMBF.R KoR THK cnAKGE. — Chuck the shot in a lathe; screw tho
funnel into the fuze-hole, to protect the threads from being injured hy the auger, and
with a common screw auger bore a hole in the axis of the shell to tho bottom.
Diameter of the auger, .7.') inch.
Lacker the shot and strap it; paint the ring around the fuze-hcde red.
To cnAnoK tiik shot. — Fill the chamber with musket powder, ramming it slightly
with a wooden drift and light mallet: screw in the iron jdug, leaving its tf)p flush
with the bottom of the large portion of the fuze-hole, and lay over it a thin leather
washer with a hole in the centre; fill the lude in the j>hig and washer wiih rifle
powder; punch 4 or •') small holes in the tin disk in the bottom of the fuze; put a
little white lead on the threads of the fuze, and screw tho fuze firmly into the shell.
Fix the spherical-case shot the same as round shot.
Canisters. (Plate 31.)
A canioler for jield serrice consists of a tin cj'lindcr attached to a sabot and filled
with CHst-iron shot. For the dimensions of CaniKter Shot, see Chapter II.
Canisters fir the mountain howitzer are filled with lead balls.
Mateiuals. — Sheets of tin, 0.02 inch to .025 inch thick (double tin); soft solder;
rosin; culots of rolled iron, .2!) inch thick; carers of sheet-iron, 0.07 inch thick for
the guns and 12-pdr. howitzers, and .1 inch thick for the 24 and 32-pdr. howitzers;
sabots; tncks.
Uten'SILS. — Paltcrun ; tracinij point; shears; e</linder of hard wood; mallet /
gain/es; furnace; solderintj iron; hammer ; pnnch.
To MAKE THE CYLINDER. — The Workman marks out the rectangle on tjje sheet with
the ]iattern ; cuts it, aud traces the line for the lap : he draws a line parallel to the
long side of the rectangle, .4 to .5 inch from it, for the length of the slits. It ia
then bent round the /«rme*-, the edge brought to the line of the lap, clamjied and
soldered.
If lumps of solder be left, they arc filed down. The cylinder is made round, and
gauged on the exterior with the large shot-gauge of the calibre, and the interior with
a cylinder of a diameter 0.02 inch less than that given in the table, which should
enter the canister: if it be not of the right size, it is unsoldered and soldered over again.
The slits arc made, and the sabot inserted and nailed with 6 to 8 nails.
Before filling the canister, dip the tin cj'linder into a lacker of beeswax dissolved
in spirits of turpentine, to prevent it from rusting. Coat the balls and the plates
with paint or coal tar.
FIXING AMMUNITION. 263
Filling canisters. — The workman, sitting astride the bench, places the canister
upright in front of him, inserts the iron bottom and places it flat on the .sabot, puts
in a tier of balls, fills the interstices with dry, sifted saw-dust, packs it with a, pointed
stick so that the balls will hold by themselves, and throws out the loose saw-dust;
he places another tier of balls, each ball lying in the interval between two ball.s of
the lower tier, and proceeds in the same manner until the canister is filled; covers
the upper tier with saw-dust; puts on the cover, places on it one of the iron Ixittoms
furnished with a handle, and strikes it with a small mallet in order to compress the
saw-dust; then removes this bottom, and turns down the slit pieces of the canister
over the cover, with a hammer. In the canisters for the 6 and 12-pdr. guns the
centre ball of the last tier is omitted. When the canister is finished, verify it^«
diameter with the large shot-gauge of the same calibre.
' Cylinders and Caps.
For the greater security of field annnunitiou, the cartridges are covered with paper
cylinders and caps. The cap is drawn oflT at the moment of loading the piece, and
in using solid shot it may be placed over the shot, to diininisTi the windage. A
cylinder and a cap are formed together by folding the paper over & formn-, which
allows a lap of about 0.7.') inch for pasting. The requisite length for the cylinder i.s
cut off from the smaller end; the rest forms the cap, which is choked, at the end
from which the cylinder is cut, on a njlindrical former which has a groove around
it marking the length from the rounded end for cutting the cap. The former should
be bored throug^i the a.xis with a .5 inch hole to facilitate drawing off the cap.
The caps for shells are stained black ; for spherical-case shot, red ; for shot, not
colored.

1 copper chixcl ; 1 copper drift, or a wrench, to open powder barrels.
Fixing shot, or sphkuical-cask, for field guns. — The bags should be filled
in the small magazine or filling room. The assistant holds the pipe of the funnel
in the mouth of the bag with both hands, the bag pressed close against the pipe.
The gauger heaps up the measui'c with powder, strikes it level with the straight-
edge, and pours it into the funnel. M'^hcu about '25 bags are filled, the gauger
takes a filled bag with one hand, squeezing the bag upon the powder ; he gives it a
blow with the other hand on the top and bottom of the bag, twisting the month of
the bag down upon the powder at the samn time ; ho then trios it with the amlVU
gauge, through which it should pass with not more than ().2.'J inc^h play; should it
not do this, the bag is emptied and rejected. These bags, filled and gauged, are

placed uprijrhf in a tub or box, and earrii-d by the araujjers into the finishinj^ room,
where the men iiro placed in pairs, sitting; astride on a bench, fai'in;j each other.
One of thctn opens a hag and level? the ])o\vilcr, the other inserts the cabof of a
strapped shot S'liiure upon the powder and draws up the end of the bag over the
shot; the first man parses about four feet of twine through the pierced stick, and
maken two turns and a double hitch with the end at the top of the sabot ; he makes
»knot ill the en<l of the twine, inserts it into the slit in the other choking stick,
and tightens the double hitch by rolling the twine on the sticks and bearing upon
the sabot : he then takes out the end of the twine from the slit, ties it in a hard
knot, which he tightens with the assistance of the choking stick, and cuts the
twine off near the knot. The second man turns down the muutb of the bag over
the sabiit, and the first makes a similar tic in the groove ; be makes another tie
below the sabot, the twine being lodged between it and the powder, to prevent the
latter from sifting in between the bag and the sabot ; he then runs the paper
cjlinder over the cartridge and sabot, leaving about two inches of the end of the
cartridge uncovered, and he makes a tie, similar to the others, in the groove of
the sabot. He now liolds the shot in the left hand and examines it, striking the
sabot with the right hand, if necessary, to bring it straight; if the shot be properly
fixed, the sabot and the bag will have the same axis ; the seams should be between
two straps, and the knots should be neither on the seams nor on the straps.
The assistants pass the cartridges through the large gauge, which is O.Ot inch
larger than the large gauge for the shot. If the size be correct, they put on the
paper cap, lay the cartri<lges on their sides in the box of the bnnd-barrow, and
carry them to the magazine. Those which will not |iass through the gauge are
banded back to the fixers, who cut the strings and put them up anew.
Can intent /or Fiilil Ouim are fixed in the same manner as shot, except that the
llrst tie is made in the upper groove of the sabot ; the cylinder is tied in the lower '
groove. The caps must be cut somewhat shorter than those for short cartridges.
For the \2-pilr. Field Hoiritzer. — The shells. Spherical-case, and canisters are
fixed in the same manner as the gun canisters.
For the Mountain Howitzer. — The sabots having but one groove, the first tie is
omitted, and the cartridge is covered with a cap only.
For the 3'2-pt/r. and 2i-p(ir. Hnwitzem. — The cartridge is not attached to the pro-
jectile. The cartridge-block is inserted with the grooved end next to the powder,
and a tie made in the groove ; the mouth of the bag is then turned down, and
another tie is made between the cartridge-block and the powder : the superfluoua
part of the bag is cut off, and the cartridge is covered with its cylinder and cap, a«
in other cases.
When the shot is attached to the sabot by a single band <>f canvas, or when if is
placed in the sabot without any strap, the cartridge-bag is drawn over it and tied
on'top; for this purpose, the bag should have ap additional length of from 2i to 3
inches.
When sabots cannot be obtained, place upon the powder a layer of tjw about 0.8 Jfe*'

Pdc/iiiKj Field Ammnnition.
Packing-Boxen for fiehl aninmnition are made of well seasoned stuff (generally
white pine), 1 25 inch thick, dovetailed, with the tenon on the ends. The top of
the box is fastened wilh six :2-inch screws; the l>ox has two handles of l^-inch
rope, attached to brackets at the ends.
The bo.xes are painted on the outside different colors, to indicate the contents of
the box. Those containing shot are painted olive; shells, black; spherical-case
shot, red ; and canisters, a litjhl di-uh. The kind of ammunition is marked on each
end, in large white letters. The place and date of fabrication are marked on the
inside of the cover.
Manner of Packing Ammunition- Boxes.
For Gi'NS. — Shot, Spherical -case, and VauiHters, Ji.red. — Laid in- two tiers across
the box, the shot or canisters alternating with the cartridges at each side. The shot
or canisters of the upper tier rest on those of the lower, and not on the cartridges.
Fob 2.'?-pdr. Ano 24-1'1)I{. nowirzERS. — Shells and Spherical-cane »S7tof. ^Placed
upright, the balls down, resting on strips of wood about .25 inch thick, placed
lengthwise of the box and nailed to the bottom, so as to prevent the fuzes from bear-
ing on the bottom of the box. Tbe balls are held down by small strips of wood
tacked with sprigs to the sides of the box, over the sabots. Tbe cartridges are laid
on the top of the sabots.
CnnititcrK arc packed in the same manner, omitting the strips of wood in the bot-
tom of the box. ^
For 12-PnR. FIELD and sroUNTAl.V howitzers. — Shells and Spherical-case Shot,
fixed. — Placed upright, the balls down, resting on strips of wood, as for the other
howitzers.
Canisters are packed in the same manner, resting on the bottom of the box.
For RiKi.En guns. — Case Shot, fjred. — Placed upright, the balls down, resting
on strips of wood, as for the howitzers. The iron part of the balls rests against
strips of wood 4 inches wide and .2.5 inch thick, nailed to the side and ends of the
box at the bottom, and similar strips placed between the rows of the balls, to prevent
the soft metal cujis from bearing against the box or against each other and being
bruised.
Canisters, ji.ved, are packed in the same manner as the case shot, omitting the
strips of wood on the bottom of the box.
In all the boxes, the small stores are placed in the vacant spaces on top of the
ammnnition.
A layer of tow is placed in the bottom of each box, and the whole coBtents are
well packed in tow, filling the box so as to be pressed down by the cover. About 3
lbs. of tow are required for a box.

AMMUNITION FOR SIFXt?] AND GARRISON SERVICE.
Ammunition for sicKC and parrison service consists of carlrtdf^cn, of sizes v;iry-
ing accoflitij; to circumstances, and the following projectiles, viz :
S/iol for 10 iind 8-incli columl.iads (model 1861), -12, 32, '2i. IS and "S-pdr. fruns.
Mhrl/x for 1(5 and S-inch cihiniVdads. 4'i, 32. '2\. IS and IJ-pdr. guns. l.'J, 10 and
S-incli morinrs. h-inch siege and S and 10-inch sea-coast liowit/.ers.
.V/''"'' "•"/-'■'""■ »*"' and cuntHter for 10 and 8-inch ccdumiiiads, 42, 32, 24, lb and
12-pdr. guns. 8 and 10-inch sea-coast and 8-inch siege howitzers.
The slielU and spherical-case shot (except for the 8-inch siege honitz.er) and the
S-inch siege and 8ca-coast howitzer canisters are attached to the sabota; the other
projectiles are not strapped.
Cartridges.
Tlie cliarge of pow<lcr for siege and garrison guns is cnclosod in a cartridge-bag
made of merino, serge, cotton, or paper, or of j)aper with woollen liottoms. Dags
made of wocdlen materials are i)referalik', as they are not so liable to leave fire in
the guns, and are more durable ; but they arc much more costly.
Merino or cotton bay are cut in two pieces in the form of a rectangle with semi-
circular ends, and sewed together to form the bag, as described in making bags for
field service. .See jiage 2i8 for the manner of making anti preserving them.
Paper botjK. — The paper is cut into rectangles to form the cylindrical part of the
bag — (be length of the rectangle being the development of the cylinder, allowing
.5 inch <in each si<le for the lap — and into circles for the bottoms. The sides of the
rectangle are lapped and sewed with woollen yarn ; one end of the bag is slit with
longitudinal cuts, I inch long, U.75 inch apart, and these strips are pasted on the
paper bottom over a cylindrical former: or a circular piece of merino is sewed in
the end of the paper bag, forming the bottom.
To close a juiper bag after being filled, the open end is foldeil d<<wn al>out .76
inch wide, and this fold is rolled on itself down to the powder, and the part which
projects beyimd the cylinder is turned in on the top of it. Two turns are taken
with strong twine around the cartridge in the direction of its length, \iii° apart,
and then tied. ,
For mortnri. cartridge-bags may be made in the same manner as for guns, their
dimensions corresponding to those of the chamber of the mortar. But, as the
charge is generally poured loose into the chamber, the bag being used only tor car-
rying it to the mortar, a gun cartridge-bag of any convenient size may he used for
mortar service.
For firing hot ihot, cartridge-bags are made double, by putting one bag within
another: care must be taken that the bags are free from holes.
For ricochet jiring. or other occasions when very small charges are required, a
cartridge-bag for a piece of an inferior calibre may be used. Or else, after the charge
is poured into the bag, place on it another bag filled with Lay, pressing it with the
CANISTERS.
^M
hands to reduce the diameter; after having shaken this bag down and rolled and
flattened the empty part of the two bags, tie them with woollen j'arn, like a bundle
of musket cartridges, placing the knot on top.
For proving ordnance, cartridge- bags are made of cotton cloth. They should be
of the full diameter of the bore or chamber.
Sabots.
Snbotii are required for the 8-inch canisters, for siege and sea-coast howitzers, and
all shells and spherical-case shot, except for S-inch siege howitzers. For canisters
and the smaller guns the sabots are turned in a lathe; for the larger calibres they
are sawed from thick pine or poplar planks, and the cavity cut in a lathe, or the
cavity is first cut by a tool of the proper curvature attached to the shaft of the
Daniel's planer, and the sabot afterward sawed out with a circular saw.
A dai/'s work. — One man can make 3.50 sabots for a 4'2 or 32-pdr. gun, or 10-ineh
columbiad, in 10 hours; or 400 sabots for a 24 or 18-pdr. gun or 8-ineh columbiad.
Cartridge-Blocks.
Cartridge-blocks are required for the columbiads, model 1844, and the sea-coast
howitzers, when firing with reduced chargei. They are made as prescribed for field
service (see page 259) — their length being such as always to make the cartridge fill
the chamber. The length of the block for any charge is easily deduced from the
length occupied by 1 lb. of powder, as given in the table. (See page 274.)
Strapping Shells.
The straps are cut and made as prescribed for nhot for field service, changing their
dimensions. Two rings or loops of tin, 0.38 inch diameter, are attached securely to
the slit strap of the howitzer and columbiad shells, for the purpose of attaching a
handle made of cord 0.1.') to 0.2.'i inch thick. A slit is made in the strap, through
which the ends of the tin loop are passed and soldered on the under side of the strap.
For the handle, pass a piece of marline through both loops and tie the two ends
together, leaving such length that the hand can embrace both branches.
The shells are placed in the sabot, and the straps put on in such a manner that the
fuze-hole may fall in one of the angles, between two straps, and that the axis of the
fuze-hole may stand at an angle of about 45° with that of the sabot. The eyes of
the shell should not be covered by the straps. The straps are fastened at each end
with 2 nniln in the side and 2 in the bottom of the sabot.
In loading the piece, care must be taken to place the fuze-hole in the upper part
of the bore.
Canisters.
They are made and filled like canisters for field service, except their dimensions,
and, instead of being attached to a sabot, the lower end of the cylinder is slit with

Grape.
A nt.inri ../grape consists of 9 shot, put together by uieans of "2 eait-i >ni lUitm,
•2 rinij» and 1 holt and nut. (See Plate 31.)
The sfjuare of the nut is 2 diameters of the bolt; it' thickness, 1 diameter. The
head of the bolt is countersink flush with the bottom of the lower plate, which has
a tint to prevent the bolt from turning when the nut is screwed on. Each plate has
.on the inside 3 beds for the shot, of a depth c<iual to half the thickness of the plate;
they are made in the form of a spherical segment, the curvature of which is the same
as that of the shot; their centres are ou equidistant radii, midway between the edge
of the bolt-hole and that of the plate. In the ui.j.er jdate are 2 holes n.2r) inch
diameter, placed opposite to each other at 0..') inch from the edge of the plate, to
receive a rope haudle.
For llie 8-i/ic/i »ea-coasl howitzer the stand of grape mu.<t be attached to a conical
gabot. The sabot is 4.2.') inches long, 7.S.'3 inches diameter at the large ond, and 6.4
inches at the small eud. The sabot may be fastened to the lower pUtc with .•screws,
or the boll may be uiade long enough to pass through it, or else ihe sabot may be
iutfei ted iuto the piece separately from the stand of grape.
Filling Shells.
WonKMEN. — 1 nion to fill ; 1 helper.
MateiuALS. — Powder; cylinders of rork-fire ; londed fitzet; fnte-pl'irj* ; tow.
Imi'LEMKSTS. — 1 pnir of nhell -hooks ; 1 handspike; 2 hnnd-hamniers ; 2 tempera
(pieces of sword blade); 2 tuw hooks ; 2 pairs of pincers; rags ; 1 cAi'«e/and 1 m'lUet,
to clean the shells and break up any hard substance that may be found in the inte-
rior: 2 searchers, for sounding cavities ; shell-tjauges ; 1 grate, to dry the Bhella on ;

1 fut, or vessel for powder: 2 baskets, for the composition and fuzes ; 1 rasp ; 1 fuze-
setter ; \ mallet ; \ fuze-reamer.
The shells are cleaned inside and out, gauged and examined that they have
no defects that would cause their rejection; that the fuze-hole is not defaced;
if there be water in the cavity, the shell is dried by a gentle heat and cooled slowly.
To FitL SHELLS FOR GUNS OR HOWiTZEKS. — The helper places the shell on tbe
block or ring of rope, the fuze-hole uppermoet, inserts the fuze-plug and drives it in

inserts the pipe of the funnel in the fuze-plug, and the principal pours in the
powder and closes the hole with a wad of dry tow rammed in securely, leaving a
portion of it projecting out.
When cylinders of rock-fire or other combustibles arc used, they arc inserted before
the fuze plug is driven.
To Kitr, MOiiTAR SHRi.i.s. — Shells arc generally- filled and the fu7,cs driven in the
battery magazines, as they are required.
The helper places the shell on a ring of rope ami inserts the pipe of the funnel in
the fuzc-hoIe; the principal pours in the bursting charge, introduces the cylinders
of rock-fire, and pushes them aside with a small stick, that they may not be in the
way of the fuze when driven in. He then inserts the fuze, which should enter to
within half an inch of the top, and with a mallet and fuze-setter drives it so that the
end of the fuze shall project not more than 0.2 incli.
To OUT THE FUZK. — The fuze is cut to the proper length, according to the range,
before it is driven into the shell, by resting it in a groove made in a block to receive
it and hold it steady, the saw running in a cut made for it; or the fuze may be bored
through to the composition witli a gimlet, at the i>roper length.
To fire 6 or Vl-pdr. Shells fr on} Mortars of largf calibre.
This kind of fire is intended only for short distances, as in the defence of <a breach,
and supersedes tho use of the stone-mortar.
Take a strong tub or half barrel, provided with two strong rope handles, and add
a. second bottom on the outside, bringing it flush with the ends of the staves to
which it is nailed.
To this bottom nail another, made of a single piece of wide 'i-iuch plank, of
suflicient length to support the ends of the staves. A block of light, dry wood, of
the diameter and length of the bore, is attached to the bottom of the barrel or tub
by nails, and the lower end of the block which goes next to the charge is covered
with sheet-iron.
Tho fuzes of the shells are cut, driven, uncapped, and the shells placed in the
barrel, the fuzes turned down. When the boU<im tier is finished, a second one is
laid; and so on to" the last, which is covered over with hay which is rammed in to
keep the projectiles in place.
Tho charge of powder is put in the mortar, the proper elevation and direction arc
given, and the barrel or tub, loaded, is raised by the handles, the block wiped clean
and introduced into the bore and set home.
Wads.
Wads are used in firing hot shot, and to prevent the ball fmm rolling out in
firing at a depression.

272 ORDNANCE MANUAL.
Imtlemexts. — 1 wad-mould, with two holes for each calibre, innile of c&st-irun
cylinders set in oak, or of two strong piece? of oak strjippcd wilii iron and joined by
a binge ; 1 dri/l for ditto ; 1 maul.
To MAKB WAns. — The bay or junk, after buviiig been picked, i* coinpresiJcd by
being beaten in the umaller mould until it nssumes the rel)ui^ite dimenNioDH ; it ir
then taken out, by raising the upper part of the mould, and wrapped clonely with
ropc-jarn pacwed over it in the direction of the axis <>f the cylinder and factcucd by
a few turns round the middle of the wad ; after which it is placed in the large
mould and again beaten with the maul an<l drift: the diameter of the wad when
finished is verified with a wooden gauge corre.-poncling to the large gauge of
the i<hot.
lu firing hot shut, a «lry wad is put next to the powder, and then a wad wbieh
has been tioaked in water for a quarter of an hour and has been permitted t<> drip
for several minutes, is placed between the dry wad and the ball : or the wet wad
may be replaced by one of clay. It should be made one calibre in length, of olajr
free from snnd or gravel, slightly moistened and kneaded.
Riug-inidn or grommrit are to 1,10 preferred where the object of a wad in merely to
retain the ball in its place. They consist of a ring of rope-yarn, about 0.7 inch
thick, with two pieces of strong twine tied ai-ro»s it at right angles with each
other. The size of the ring is the full diameter of the bore, in onler that it may fli
tight. These wa4s may be attached with twine to the utraps, or to the ball*; or
they may be inserled. like other wads, after the bull. These wads may be made of
straw formed into rings of the proper site, and wrapped with twine and tied to
the ball.
Sabots of Shavings.
In positions where the pieces of sabots might prove dangerous to our own troopa,
as in firing over their beads when making an attack, sabots made of thi< k shavings
of soft wood or pasteboard are used. For this purpose select black walnut, pine,
or fir, not too dry. and as free as possible from knots.
Pieces of the proper length and width are dressed out, and by means of a coarK
plane shavings are cut .06 inch in thickness. Each shaving is rtdled in a circle on
a cylinder of iron in which a longitudinal groove is cut. One end is thinned down,
moistened, and inserted in the groove, and the shaving is rolled on the cylin<ler, the
smooth side turned outward: one man turns the cylinder by a crank making three
revolutions, the other holds the shaving so as t<» roll it evenly on itself, pulling it
tight.
The different turns are then tacked together, the tacks being riveted on the inside
against the iron cylinder: the end is thinned down with a rasp, and the sabot taken
from the cylinder is immersed in a warm bath of thin glue. Pasteboard rn«y be
used instead of shavings of wood. The sabot is attached to the shell by means of
four pieces of tape 1 inch wide. Each piece is folded around the sabot, and the
ends sewed together: the seam is turned on the inside of the sabot and is made Cm(
FUZE-PLUGS.
ff%
to it by tacks, the four pieces of tape beinfr ;ii;.iclied to the sabot at the extremities
of two diameters perpendicular to each other. The sabot is laid down on the table
and the shell placed in it, the fu7,e-hole down ; the ends of the tape arc then drawn
together and tied on top of the shell with a piece of strong twine.
Fuze-Plugs.
Fuze-plugs are made of brass, or of close grained wood, well seasoned. They
are turned to a size a little larger than the fuze-hole, but of the same taper, 2.5
inches long; a hole is bored through its axis and reamed out to receive the paper
fuze, and the large end is couuterbored to receive the wat«r-cap. The plug is
reamed out after it is driven, and the recess for the water-cap is tapped with 12
threads to the inch.
If wooden plugs be used, a short hollow c_vlinder of brass, .5 inch long, .15 inch
thi'^k, is inserted in the recess before the plug is driven, and afterward tapped to
receive the water-cap.
The water-cap is a brass plug, .5 inch long, .6 inch in diameter, chased with 12
threads to the inch: one end has a shallow recess cut in it, .1 inch deep, larger at
bottom than at top: a hole, .1 inch in diameter, is bored through the middle of the
cap, and a hole is bored from either end into this transverse hole, but meeting it at
points .26 inch or more apart: those and the recess at the end arc filled with mealed
powder paste.

MATC'IIES, FUZES, AND PRIMERS.
Slow-Match.
Slow-matrli IK prpfiarcii rope, which is used to keep nn<l cnrry fire : it burns
■lowlj, with a firm, hard coal, and is not easily extin);uii<hed.
Matkriai.h. — Urmp or /fax rupf of .3 Strands, slightly twisted, about 25 yards
long, and of a uniform diameter of .6 inch ; aretnte nf Und (sugar of lead) ; iraier.
Utknkii.S. — 1 kcttir ; 1 tub; 2 woodtH upatulat ; lerert ; twiiliHg-irinrh ; mate, or
hnir clolh.
Mrtboii with acrtate or LRAD. — Boil the rope for 10 minutes in water holding
in solution l-20th of its weight of acetate of lend: remove it with spatulas into the
tub, or let it remain in the cold solution until it is thoroughly saturated. First
twist it over the kettle, and then, by attaching one end to the hook of a twisting-
winch, twist it hard, keeping it stretched by means of a stick passed through a loop
at the other end, at the same time rubbing it smartly, always in the same direction,
from the honk, with co«rse mats, hair cloth, or cnttings of buff-leather, until th«
diameter of the match is reduced 0.1 inch and it \\a» a uniform twiKt ami hardness.
Stretch it on jioles or on a fence to dry. and put it up in neat coils, well secured.
Match thus prepared burns 4 inches in an hoi^r.
Mktiioi> dv lkaciiikc. — If sugar of lead cannot be procured, the rope may be
simply leached. For this purpose, it is put into u leach tub and steeped in pure
water for 1'2 hours : this water is then drawn off and rejdaced by lye prepared in a
boiler, with a ((uuntity of ashes equal to half the weight uf the rope, to which 5
per cent, of quicklime is added. This lye. with the ashes, is put. after being
warmed, into the hopper of the tub. and when it has run through and remained
some time in the tub it is drawn off, heated again, and poured back en the ashes.
This operation is repeated several times in the course of 24 hours, which is the time
required for the rope to be well leached. After being taken out and twisted with
sticks, it is steeped for 5 minutes in hot water, beihg stirred at the same time, and
the operation is finijihed as b»fore. Match prepared in this manner burns 5 inches
in an hour.
Cotton rope, well twisted, forms a good match without any preparation.
A slow-match may be made of strong paper by immersing it in a warm solution
of nitre, of about 1 pound to 2 gallons of water. When dry, roll each sheet sepa-
rately, pressing it firmly, and pasting the last turn.
A half sheet thus prepared will keep fire for threr hourt.
Slow-match weighs from 3 to 5 ounces to the yard.
Packing. — Slow-match is packed in tight casks or boxes. A cask iO inches
high, 24 inches diameter (weighing 60 pounds), contains 150 pounds of match.
The casks and boxes should be marked with the kind and quantity of match, place
and date of fabrication.
Dimensions of a box to hold 200 pounds hemp or 220 pounds cotton match — 14
QUICK-MATCH. 277
inches long, 2S inches wide, 18 inches deep; weight, 87 pounds. It is made of
bo<ard3 1 inch thick, ends li inch, and has corner-pieces of hard wood, 2.25 inches
square.
Quick- Match.
Quick-match is cotton yarn, of several strands, saturated and covered over with
an intlammable composition ; it is used for communicating fire from point to point
in fireworks, etc.
Matkkials. — Mealed powder ; cotton yarn, wound in loose balls of convenient
size (say 1 pound, which will measure about 1,000 yards), such as is used for
candlewick; when doubled and slightly twisted in the fingers, it should be about
.07 inch in diameter. Gummed brandy or tchiskey, in the proportion of 1 ounce of
gum to i gallon of spirits: the gum is first dissolved in the smallest quantity of hot
water or vinegar, and afterward mixed with the whiskey. Strips of paper ; thread.
1,000 yards of quick-match require 1 pound of cotton yarn, 8 pounds of mealed
powder, IJ gallon of spirits, and 2i ounces of gum arable. Weight, when dried, 9
pounds.
Utensils. — Wooden or copper honh ; 1 quart measure ; funnel or frame ; reel.
Preparation. — Steep the balls of yarn in the gummed whiskey until they are
thoroughly saturated.
Make a paste of mealed powder, by mixing 1 quart of gummed whiskey to 2
pounds of powder, and put a layer of it about i inch deep in the bowl ; on this
spread a coil of the cotton by unrolling the ball and distributing it equally on the
surface of the paste until there are 5 or 6 yams over one another ; put another
layer of the paste ; and proceed in this manner until the bowl is full, taking care
not to entangle the strands : the last layer of paste should be a little deeper than
the others. After the cotton has been 3 or 4 hours in the bowl, wind it on a reel,
or stretch it on nails 40 or .50 feet apart, making it pass through a funnel, or the
hand, filled with the paste, and taking care that the several turns of yarn do not
touch each other. Before it is dry, dredge it with mealed powder ; lot it dry slow-
ly, then cut it off from the reel or nails and put it in bundles.
During the winter, quick-match shoulil be made in a warm room.
Match thus prepared should be hard and stiff, and the composition should hold
firmly on. 1 yard burns, in the open air, 13 seconds.
By using vinet/ar, a match is made which burns less rapidly, in the proportion of
4 to .5; and with pure water, in the ratio of 4 to fi. Alcohol makes a quicker
match ; but it cannot be gummed, and the composition does not stick.
A slow kind of match is made by adding, sulphur to the mealed powder; with
one-sixth of sulphur, 1 yard of match burns 22 seconds ; with one-fifth, 33 seconds ;
with one-third, r)3 seconds; with one-half, 162 seconds.
Quick-match enclosed in tubes burns more rapidly than in the open air, and
more so in proportion as the tubes are smaller. To communicate fire very rapidly,
it is enclosed in paper tubes called leaden.

compactly driven. The shorter drifts are used as the ca«e is filled.
Port-fires should not be primed with mealed powder: after they are driven, the top
of the case should be turned in and beaten down : thus both ends of the composition
are secured.
Port-fires made as above described burn 10 minutes each, or IJ inch per minute.
A dny$ tcork.—A man can drive 120 port-fires in ten hours.
Packiso. — Port-fires arc packed in boxes containing 100 or 200 port-fires. The

contents of the box should be marked in white letters on each end, and the place and
date of fabrication on the inside of the cover.
Fuzes for Mortar Shells.
The hard, close grained woods are best adapted for making fuzes: beech or ash
is generally used. It should be dry, sound, free from sap, knots, worm-holes, or
shakes.
To TURN TiTE FUZE.— The helper saws the plank into lengths equal to that of the
fuze, and then into prisms, taking off the edges, and centring it on each end. The
turner puts the fuze thus roughed out in the lathe, turns its exterior, and graduates
it, by means of a steel gauge, into inches and tenths of an inch, commencing at the
bottom of the cup. When a number have been turned, the turner puts each fuze
into a chuck, bores it, and makes the cup, with a tool for that purpose.
The fuzes should be carefully inspected, and verified with gauges, and tho.oe
rejected which have splits, knots, or worm-holes, or which have not the proper
dimensions.
A day's work. — One turner can turn 500 fuzes, or turn and bore S-'jO, in ten hours.
TO DRIVE FUZES.
Materials. — empti/ fuzes ,- fuze composition, dry; mealed powder, dry; pastel-
paper. •
VTEtiSiLfi.—Driviiifjf-hlocIcs with holes of the size of the fuze; benches: mallets—
for the 13-inch, 10-inch, and 8-inch fuzes weighing 1 lb., for smaller fuzes, weighing
i to j lb. ; steel drifts shod with copper, the shortest with a mark 0.2 inch from the
end; copper ladles to contain suiBcient composition to make a height, when driven,
equal to 1 diameter of the bore; copper pant ; brushes.
Preparation of the composition.— The composition for 8 and 10-inch light
mortar fuzes is 2 parts of nitre, 1 of sulphur, and 3 of mealed powder; for 10 and
13-inch heavy mortars, 2 of nitre, 1 of sulphur, and 2^ of mealed powder. The
composition must be thoroughly ground and mixed with a muUer, or in a leathern
barrel with brass balls. The time of burning will vary according to the quality of
the materials used (especially of the mealed powder) and the degree of their
admixture. Trials should be made with each composition by driving several fuzes
and getting their time of burning. There should not be any great variation in the
times of burning of the different fuzes, of the same composition. Fuze composition
should be prepared only a short time before being used, and should be preserved in
close vessels in a dry place.
Driving.— The workman is seated, his driving-block in front of him, .and a bench
to hold a pan of composition at his right hand. He takes a fuze, cleans it of all
foreign matter, inserting the drift to the bottom of the bore: he then drops the fuze
into the driving-hole, takes a ladleful of composition, passing tlie drift along the
edguK of the ladle to strike off the surplus ; pours the composition into the fuze,
280 ORDNANCE MANUAL.
Rtrikes it two gentle blow? with the mallet, inserts the drift, prepsinR it down on the
corapogition, piving the fuz.c tw(i sliglit blows to settle the compojition. The work-
man strikes the drift 2\ blows in volleys of 3, raising the mallet about 1 foot each
blow, and moving the drift after each volley. He puts in another ladleful and con-
tinues as for the first. Care should be taken to put in equal charges of composition
each time, and to giro to each la<lleful the same number of blows, and with the samu
force.
Fuf.en may be driven by pressure in a screw press.
Pkiminu. — Fur.es are all driven to the same height by means of a mark on the
short drift, or the composition is bored out with a gouge to the same dejith. They
are j)rimed with meiiled p<iwder for about O.'i inch driven with the same force as a
ladleful of composition. The cup is filled with a jiastc of mealed p.iwder and spirits
of wine or strong whiskey, and laid aside to dry: it is then covered with a email
piece of paper, over which is pasted a cap of strong water-proof paper, marked with
the number of seconds the fuco burns to the inch.
Fuzes for Jleavy Guns.
The fuze consists of a paper ente charged with fuxe composition ; it is inserted, at
the time of loading the gun, into a brass or wooden plug previously driven into the
fuze-hole of the shell.
TO MAKK THE CASES.
Materials. — Lng paper, or thin drawing paper: itinglaai.
Utensils. — pnttmi of wood, in the form of a rectangle joined to a trapesoid ; iron
former 0.3.') inch diameter ; kui/e, ylue put, brutliet.
Making the case. — The paper is ?ut to the proper size by means of the pattern.
The wh(de length of the strip must be determined by trial, for each kind of paper, to
give the case the proper diameter. The strip is rolled hard on the former, beginning
with the large end, and is glued after the first turn.
When the case is dry. it is smoothed with a fine file or sand-paper.
Preparation or the composition. — There are three different compositions used,
one inch burning 10 seconds, 14 seconds aud 20 seconds, respectively.
The following are about the proportions required to make these compositions; but
as their time of burning is subject to considerable variation, according to the quality
ot the ingredients aud the manipulation in mixing them, the exact proportions must
bo determined by experiment :
Xo. 1. — 26 nitre. 9 sulphur, 14 mealed powder.
No. 2.— 26 " 9 ♦• 12 "
No. 3.-26 " 9 " 10
The composition is carefully mixed, as deiiribed on page 27y, and several fuies
are fir.*t driven aud their times of burning determined, and the proportions varied,
if necessary, to produce the required result.
FUZES FOR FIELD GUNS AND MOUNTAIN HOWITZERS. 281
TO DRIVE THE FUZE.
Materials. — Empti/ cases; fuze camjiosition.
2 lbs. of composition are required for 100 fuzes.
Utensils.— 'i?rass moulds in two parts, which are held together by a wedge or
cam : the moulds have holes for 4 or 5 fuzes ; steel drifts, 0.35 inch diameter : knt'/e;
mallet, weighing J lb.
Driving. — The mould is put together and secured ; the empty cases arc inserted
and driven gently in; their upper ends projecting above the mould are slit with a
knife into 4 parts. The composition is put in and driven as described on page 279,
giving 15 blows to each ladleful, which will make 0.25 inch in length of the fuze.
Cutting. — The fuze is inserted in an iron gauge, the bore of which is of the same
size and taper as the fuze, and its width is the true length of the fuze, 2 inches.
The projecting ends of the fuze are first sawed off with a fine saw and then trimmed
with a knife.
The fuze is stained the proper color according to the composition used — fuzes of
No. I composition being yellow ; No. 2, green ; and No. 3, blue— and the number of
seconds that each inch will burn is marked on each fuze.
Packing. — Fuzes are put up in bundles of 10 each ; fuzes of the same color being
put in the same bundle, which is labelled with the kind of fuze and its rate of
burning.
Fuzes for Field Guns and Mountain Howitzers.
The fuze for shells and spherical-case shot for field and mountain service is that
known as the "Bormaun fuze." It consists of a circular disk of soft metal con-
taining an annular space charged with mealed powder. The outer circumference of
the disk is chased with the threads of a screw to secure it in the shell. The annular
space for the composition is concentric with the outer circumference, and connects
at one end by a hole with a small magazine in the centre of the disk, filled with
rifle powder and closed on the under surface by a thin disk of tin. The fuze is
charged from the under side, by pressure, and a ring of the same metal is pressed
firmly on the composition.
The composition is thus securely protected from accidents, and the fuze is
screwed into the shell in the laboratory ; the metal covering the composition on
top, being left thin, is easily cut with a knife or cutter, at the moment of loading,
and the composition exposed at the required point to the action of the flame. The
graduations into seconds and quarter seconds are marked on the upper surface of
the disk. The time of burning of the whole length of fuze is 5 seconds.
TO CAST THE FUZE.
Materials. — Tin and lead in equal parts; roain; tallow.
Utensils. — Moulds for the fuze, moulds for the ring, hac/csair, nijypers, mallet,
kettle, ladle.
Casting.— Melt the lead and tin together: heat the moulds so as not to chill the
282 ORDNANCE MANUAL.
metal in casting. Fill the mould with the melted metal, and tap it gently with the
mallet to make the metal fill the small parts. Cut off the gate with the saw, and the
ends of the ring with the nippers.
It ha-8 been found convenient in opening and closing the moulds to attach the two
parts of the mould for the fuze and also for the ring to the jaws of a bench-vice, so
that both moulds arc opened and closed by the same movement of the screw. Tho
fuze-mould is kept hot by means of iron disks which are heated and hung on tho
arbor which supports the moulds.
A mould of more approved pattern has been devised, by which the casting is
expedited.
TO CHARGE THE rUZE.
Matp.riai.S. — }ffnhd powder ; muskfl powder ; rifle powder ; dink* of tin.
Vtknsii.s. — A strong tcrew presi, annular charger the size of the ring, annular
drift, fidl drift, round drift.
Take the mould in which the fuze was cast: place tho fuze in the parts of the
mould containing the screw and tho upper or graduated side, and secure the mould
by a ring driven on it.
Draw up the piston, and fill the charger by pressing it into the mealed powder
contained in a shallow pan. Place the charger over the groove, and force down tho
piston, transferring the powder into the fuze. Insert the buttun in the magazine
and the pin in the priming-hole, to preserve their shapes: place the ring on tho
powder, and with the annular drift force it down by means of a strong si-rew [tress,
bringing the ring flush with the surface of the fuze; rivet the ring in it« place with
another drift. Withdraw the button and pin: charge the priming-hole with rifle
powder and till the magazine with musket power: cover the magazine with a disk
of tin, and rivet it in place by means of first a flat drift and then a round one, which
turn down a part of the metal of the fuze over the disk.
Remove the fuze from the mould, place it in a screw-chuck made to fit it, and
turn off in a lathe the lower surface smooth and to the proper thickness.
The powder of the fuze is now perfectly sealed up from tho air. The fuze may
b« varnished.

Friction Primers for Cannon.
The friction primer for cannon is a small brass tube filled with gunpowder, which
is ignited by drawing a rough wire briskly through friction composition, contained
in a smaller tube inserted into the first, near the top, and soldered at right angles
to it. A lanyard, with a hook attached, is used to ignite the primer.
284 OUDNANCE MANUAL.
The fricli'on primrr is cuiu])0sc<l of 1 larye tube: 1 uhurt tube; 1 trlre rubber; fric-
tion euwpoiition ; mutkrt powder ; wax.
The lottff lube is mndo from a circular disk of No. 19 8hcct-brii.»!<, 0.02 inch in
diameter, by means of a scrie« of 5 punches and dies, grudually dimininhinfj^ in
8i7,e to the last, which i« of the required size of the tube. The brass must be an-
nealed before each punchin;^.
The lube is cut to the prescribed length, measuring from the closed end, by
means of a circular saw, and the holes for the short tube and wire rubber are
drilled, and the burrs removed. Length of the long tube, 1.76 inch; exterior
diameter, .10 inch; interior diameter, .176 inch; diameter uf holes, .16 inch and
.00 inch.
The thort tube is formed from the long one by using two additional punches and
dies, reducing the site each time. It is cut to the proper length by circular saws
placed at the required distance apart, and the burr removed by rolling in a barrel.
Length of the short tube, 0.44 inch; exterior diameter, 0.16 inch; interior diame-
ter, .133 inch.
One end of the short tube is dipped into a solution of chloride of zinc, inserted
in the hole drilled in the long tube, heated to redness in' the flame of a spirit lamp,
and soldered with soft solder; it is then washed and dried.
The wire rubber is ma^le of \o. 16 bra.ss wire, annealed, cut to the proper length,
and pressed flat at one end by a machine for that purpose. The flat end is trimmed
by a punch and die with dentated edges, and the tip is anneale<l in the flame of a
spirit lamp. Length of wire, 3.4 inclies; length of flattened end, O.lj inch.
The frirtiou compotitiou is made of 2 parti of the tulphurel uf antimun^ and 1
part of the chlomte of putatia, moistened with yumnird iroltr — 60 grains of gum
arabic in 2 ounces of water to 1 pound of composition.
The materials are first pulverized separately, mixed together dry, moistened with
the gum water, and ground in an iron mill, such as is used for grinding [taint.
CuAiiGixG AND VAK.MSHiNG. — The small tube is charged by pressing the open
end in the friction composition spread on a flat piece of iron and brought to the
consistency of soft putty, the long tube being closed its whole length with a
wooden or metal plug.
A conical hole is made iu tho composition, while yet moi?t, with a conical drift,
and the surplus composition removed; the wire rubber is passed through the short
tube and through the small hole in the long tube, the round end first, leaving the
annealed tip projecting out of the open end, which is then closed by pressing
the top and bottom together firmly with pincers, and bending the tip against the
bottom.
The cud of the wire rubber is doubled on itself and twisted, leaving a loop 0.2
inch diameter, and then bent alongside the long tube for packing.
The head of the long tube, including the short tube and the joint, is dipped into
shella<> varnish colored with lampblack.
When dry, the long tube is filled with musket powder and closed with beeswax,
mixed with J its weight of pitch.
PERCUSSION-CAPS FOR SMALL ARMS. 285
Both ends arc touched with varnish and the tube thoroughly dried.
Packing — The tubes are first put up in bundles of 10 each, wrapped in water-
proof paper; 10 bundles are packed in a tin box. painted or japanned: 100 tin
boxes are packed in a box made of 1-inch white pine boards, dovetailed.
The contents of the tin box, place and year of fabrication, are stamped on the

Percussion-Caps for Small Ar7ns.
The cap for small arms is made of copper. It is very slightly conical, with a
rim or (lanch at the open end; it has four slits, extending about half the height of
the cap.
The cap is charged with fulminate of mercury, mixed with half its weight of
nitre : the object of the nitre being to render the fulminate less explosive and to
give body to the flame. To protect the percussion powder from moisture, and also
to secure it from falling out, it is covered over, in each cap, with a drop of pure
shellac varnish.
The copper ft)/- making the caps is obtained in sheets 48 inches long and 14 inches
wide, weighing 3 lbs.: a variation of 4 ounces, more or less, is allowed. The cop-
per should be pure, free from seams, holes, or blisters, well annealed, and as evenly
rolled as possible, with straight and smooth edges.
The copper is cleaned by immersion in a pickle made of 1 part (by measure) of
sulphuric acid and 40 p<arts of water; it is secured with fine sand and a hand-
brush, and washed clean in running water — after which it is well dried in clean
saw-dust and rubbed over with a cloth slightly oiled: it is then ready for the ma-
chine.
To PREPARE THE FULMINATE OP MERCURY. — Dissolve, in a glass retort capable of
286 ORDNANCE MANUAL.
holding aV)out a half gallon, 10 oz. of pure mercury in 5 lbs. of nitric acid of the
specific gravity of 1.40. The solution is made by placing the retort in a water or
sand-buth of about 120° or exposed to the sun's rays on a warm day. The vapors
which como over arc very deleterious, and should not be inlialed.
When the solution is complete, pour the liquor into a widc-mouthc<l glass vessel
capaltle of holding 8 to 10 gallons, into which 5. 675 lbs. of alcohol (abi)ut CJ pints)
of the spocifio gravity of 0.85 have been previously poured. Care must be taken
U) pour the nitrate of mercury on the alcohol, as the reverse mode of mixing is dan-
gerous. Great heat is evolved during the effervescence which ensues from the
mixture, and the glass vessels used should be well annealed and of a form to bear
a high heat without breaking. Carboys of thin flint glass, without mouth-rings or
any alinipt change in thickness, are best. The operation should be performed at a
safe di.-<tancc from the fire, as the vapors of ether disengaged are highly inflamma-
ble. When reddish fumes begin to appear, they must be reduced by adding alcohol
in small ()nantities.
The proportion of alcohol used in the whole operation varies according to the
strength of the acid and alcohol, and also with the state of the weather. The
proper quantity is that which is just suflBcicnt to keep down the reddish fumes, and
is determined by trial with the materials used.
When the elfcrvescence has ceased, the fulminate of mercury is found at the
bottom of the vessel as a brownish precipitate. A small ijuantity of water is
poured in, ami the contents transferred to the washing tub, where it is repeatedly
washed in soft water, until tlie water no lunger reddens litmus paper.
The fulminate is in the form of very small crystals, of a light gray color and
brilliant surface. If the operation be well performed, no metallic mercury will be
reproduced. The weight of the fulminate, when dried, is about 14 per cent, greater
than that of the mercury used.
If the proper proportions be not used (or if the materials be not of good quality),
the product will be, instead of fulminate, an impalpable, yellow powder, which is
incombustible. When this is observed, the result may generally bo corrected by
varying the proportion of alcohol in the mixture.
The fulminate of mercury is kept under water, in stone jars, which should be pre-
served from frost.
A day's icork. — In a warm, clear day, 1 master and 2 assistants can make, and
partially wash, 100 lbs. of fulminate in 10 hours.
To PREPARE THE PERCi'SsiON POWDER. — Take aboat 2 lbs. of the wet fulminate
in an earthen dish ; drain the water from it, and spread it on sheets of blotting
paper until it is sufficiently dry to assume the granular form and retains only 20
per cent, of moisture. In this state add to it bO per cent, of its weight of refined
pulverized nitre, and thoroughly mix the ingredients, on a wooden table, with the
hand and a wooden spatula, and pass it several times through an iron sieve Xo. 3:
spread it on sheets ot paper in quantities of ^ lb. each, and dry it in the sun or in a
room warmed by flues. When quite dry, pass the i lb. parcels through a fine hair

sjeve, by rubbing it with the hand, and put each parcel in a separate box, made of
paper, varnished on the inside and outside with shellac varnish and having a loose-
ly-fitting cover. The boxes should bo kept in a small magazine standing apart
from other buildings, upon shelves covered with cloth, to prevent friction in
moving, and be issued one at a, time to the person having charge of the cap
machine.
Making and fillikg the caps. — Both of these operations are performed by
the same machine. The sheet of copper is adjusted on the table of the machine.
The hopper is filled with the percussion powder, and the machine put in motion.
The star or blank is cut by a punch and transferred to a die, where it is formed
into a cap by a second punch. The cap is caught in the notches of the revolving
horizontal plate, and carried, first under the hopper containing the percussion pow-
der, where it receives its charge of i grain, and then under a punch, which presses
the charge firmly into the cap, and lastly to the drop-hole, where it falls into the
receiving drawer.
The hopper is supplied from time to time from the i lb. box, while the machine
is at rest, using a small copper scoop for the purpose, and the bo.\ returned to its
special closet, at least one yard from the machine and above its level, before the
machine is put in motion.
As a cap is occasionally exploded under the punch in charging, all dust of per-
cussion powder should be frequently removed, and only a small quantity of percus-
Bion powder kept in the hopper. The receiving drawer should be emptied after
each sheet of copper is completed : 2,314 caps are made from each sheet 48 inches
long and 14 wide.
A day's work. — The average work of ten hours, including all necessary stoppa-
ges, is 31,000 caps for each machine.
To PREPAnE THE VARNISH. — Dissolve 1 lb. of the best gum shellac in 1 qt. of
rectified alcohol containing 95 per cent, of pure spirit. The solution is made most
readily at a te"mperature of about 120°. It must be stirred frequently until all the
gum is dissolved. It is made and fit for use in 4 hours.
The varnish is best made and kept in glass vessels. 1 qt. of alcohol and 1 lb. of
shellac make 1.4(5 qt. of varnish. A small quantity of alcohol is occasionally
added to thin the varnish when it is used. i
Eighteen quarts of varnish are required for 1,000,000 caps. Two quarts of alco-
hol are required for thinning the varnish.
To VARNISH THE CAPS. — The caps are put into holes in counting-plates made of
sheet-brass, 15 inches by 12 inches, .05 inch thick, held in a frame of brass rods .35
inch square. This is quickly done by taking a parcel of caps on the plate and
shaking it sideways: the caps settle themselves in the holes. When the plate is filled,
the defective caps and those which have lost their charge are easily detected by the
eye, and are replaced by perfect ones. The plate is placed in its bed in the varnish-
ing machine, which is worked by hand, and each row of caps is brought in turn under
a row of wires, Avhich are alternately dipped into a pan of varnish and then into the
caps, leaving in each a drop of varnish.
288 ORDNANCE MANUAL.
The quantity of varnish placed in each cap can be rcpulafed by the sifo of the
wires, or by the depth tu which they cuter the varnish. The ru)i8 remain in tho plate
30 to 40 minutei<, when the varnigh ie sufficiently net to allow of their beiiip turned
into a tray for dryinp. Thefo trays are of wood, 18 inches long, 12 inches wide, and
1 inch deep, and contain 2,500 caps. Tho caps remain in the tray* fur .'J days* in a
room lieated to about 100°. They arc then put into bnpf, and kept at the same
temperature for 10 days longer, before they arc packed in boxes.
A diiy'i tcork. — One boy can count and varniish 7,000 caps per hour.
Packing. — Tho caps are put into bags of strong cotton duck, 10,000 in a bag, and
ten bags are packed in a woodeu box. The box is lined with thick paper, tho bags
are packed in tow, and the cover is fastened with six 2-inch wood screws.
Uaoh anh i-A( king-boxes. — Tho bags are 6 inches in diameter and 13.5 inchei

Note. — Experience has shown that it is not safe to try to wash the percussion
powder from partly filled caps. A lot of unvarnished caps, imperfectly filled, being
soaked in water for several days, became coated with' a substance much more explo-
sive than the origiual fulminate.
The percussion powder must be burned out, and the cap polished by roiling in a

PITCHED FASCINES. 289
iNCEXDiA i;y compositions, lights and signals.
Rock-Fire.
Rock-fire is a composition which burns slowly, is difficult to extinguish, and is used
to set fire to buildings, ships, etc. That which is put into shells is cast in cylindrical
cases of paper hnving a priming in their axes.
Materials. — Roiin, ^ parts ; sulphur, 4; uitre, 10'; rcguhts of antimony, 1 ; mutton
tallow, 1; turpentine, 1.
Utensils. — A furnace of second kind (page 24.'?), or large kettle in the open air-
tpatulas ; ladle with long handle; balance and weights; sieves.
Preparation op the composition. — Pulverize the sulphur, nitre and antimony
separately; mix them with the hands, and pass them through sieve No. 2; melt the
tallow first, then the rosin, stirring the mixture with spatulas; add the turpentine
and next the other materials, in small (luanlitics at a time, stirring the whole con-
stantly with large spatulas.
Let one portion of the composition be melted before more is added, and work with
great precaution to prevent it from taking fire. When the composition becomes of
a brown color, and white vapors are disengaged, the firo is permitted to go down •
and when the composition is sufficiently fluid, the cases are filled with the ladle not
more than three-fourths full.
Paper cases and phiming-tubes. — The cases are made ofrocket paper, in the
manner described for port-fire cases. The priming-tubes are made of cartridge paper
pasted after the first turn, and rolled hard.
Filling the cases. — The cases are arranged in a frame, the lower end of each
inserted iu a socket, in the centre of which is a spindle to support the priming tube.
The upper ends of the cases are held in place by short cylindrical spouts attached
to the lower side of a reservoir which rests on the top of the frame. The composition
is poured into the reservoir, and tlie frame is gently shaken to settle the composition
in the cases until they are filled.
When the composition has become solid, the cylinders are taken out of the frame
and trimmed; the priming-tubes are charged with composition No. 1 for mortar
fuzes, driven the same as mortar fuzes ; the ends of the cylinders are last dipped in
mealed powder.
When rock-fire cannot be had to put into shells, the p.aper cases may be filled with
port-fire composition, driven as usual; or pieces of port-fire may be inserted in the
shells.
Pitched Fascines.
Pitched fascines arc fagots of dry twigs covered over with an incendiary compo-
sition, and used to set fire to buildings or to lightup at work.

TO MAKE riTf-flEr) FASCINES.
MATF.niAL. — Di-)! hrnnchm, about 0.5 inch diameter, or other light, combustibftj
wood: I/-OII irire, about 0 5 ineh diameter.
Utensils. — 4 pickrts, 40 inches long and li inch diameter ; ryliudrt'cnl tiirl-n, 20
inches long, 11 inch diameter; 2 tracc-rope» ; 1 mpc for a cap-^tan ; 2 lever* ; I $maU
cord; I flat puiirh ; 1 miv) OX hill-hook ; 1 block.
To MAK.K THE KAS<iNE. — Form 2 crotchets, 1 foot apart, with the -lO-inch pickets;
cut the liranchcs 20 inches long, and tie them in the middle of their length, and about
2 inches from their ends, with annealed wire, and |dace in the axis a cylindrical stick,
intcndcil to preserve a vacant space: draw the branches tightly together, that they
may bold the composition better, and cut off tho end» square.
TO riTCn THE KASCl.VES.
MATKniAI.R. — I'it'h ; tar; miilton (tilloir ; liiincxl oil, in a bowl; »nir.ilii»t, in A
barrel ; rock-fire for priming.
Utensils. — 2 potn in a furnace of tho first kiml ; 2 Kjintiilii* : 1 ln<ll' with a long
handle: 1 rnnnll iron fork, with a long wooden hanalc; 2 tiib» ; plank:
The fascines receive two coats of composition.
Firnt root. — Melt 20 parts of pitch and 1 of tallow in the pots, filling them not more
than half full. Having first well oiled the cylindrical slick, plunge the fascine into
the liiiuiil with the fork, first one end, then the other, each time pouring on the upper
end two ladlefuls of the composition. Let the composition harden, holding the
fascine over the pot, turning it slowly, and then immerse it in the tub of water.
The assistant, with his hands covered with oil, fashions the fascine, rolling it on
the bottom of the tub, and places it on the planks.
Second coat is put on 24 hours after the first; it is composed of e<iual parts of
pitch and rosin, melted and mixed together in the pot. The cylindrical stick ii
taken out, and the fascine immersed in the composition, as with the first coat: it is
permitted to drip, and is then laid in saw-dust and powdered all over with it. A
fascine requires about 1.1 lb. of each composition. Fascines should be primed only
& short time before being used. For this purpose dip each end, for a distance of »
half inch, into a kettle holding melted rock-fire.
When used for incendiary purposes, fascines are placed in piles, and pieces of
quick-match and port-fire scattered over them to make the whole mass take fire at
once.
Torches.
Torches are made of a number of strands of twine slightly twisted, or old rope,
covered with a composition to give light.
Materials. — Hemp ttritie, slightly twisted, about 0.08 inch diameter; cartridge
thread ; mutton talloie : j/ellow wax; roitin ; glue; quicklime.
Utensils. — I pot ; 2 upatulai ; 1 ladle; glue pot and bath; knife; 1 mould.
'm
FIRE-BALLS. 291
PuEPARATiON. — Melt in the pot 1 part of t.i'li<\v, 2 of yellow wax. and 8 of rosin,
stirring it with spatulas. The twine is formed in hanks of about 40 threads, 3 feet
long, cut at one end, and tied with twine, forming a handle, at the other.
The hanks are immersed for ten minutes in the composition, and then drawn
through a mould of the proper size. They are suspended by the handle in a shady
place to harden ; 24 hours after, they are painted over with a warm solution of
a half pound of quicklime and J of an ounce of glue to a quart of water.
With old rope. — Boil the rope, well beaten and untwisted, in a solution of equal
parts of nitre and water ; when dry, cut it iu pieces 4 feet long ; tie 3 or 4 of these
pieces around a piece of i)ine wood, 2 inches in diameter and 4 feet long; cover the
whole with a mixture of equal parts of sulphur and mealed powder, moistened with
brandy; fill the intervals between the cords with a paste of 3 parts of sulphur and
1 of quicklime. When it is dry, cover the whole torch with the following compo-
sition :
Pitch, 3 parts ; Venice turpentine, 3 parts ; turpentine, i part.
Tarred Links.
Tarred links are made of old rope, covered over with a composition to give light.
Matkrials. — Old nlow-match or rope ; cartridge thread ; endn of rope. One link
requires i lb. of tow and 1 to li lb. of composition.
Utensils. — Mallet; knife.
To MAKE THE LINKS. — The old rope is well beaten with mallets: the short ends
are tied together with cartridge thread. The links are formed by coiliug the soft
rope around the hand, in coils of 3 inches interior and 6 inches exterior diameter.
loosely tied with thread.
To TAR THE LINKS.— The links are covered with composition as described for
fascines.
Tarred links burn one hour in calm weather, half an hour in a high wind, and
are not extinguished in the rain. Two of them are put in a rampart grate on a
bed of shavings. The grates are placed about 250 feet apart.
Fire-Balls.
Fire-balls arc projectiles of an oval shape, formed of sacks of canvas filled with
combustible composition. They are used to light up the enemy's work, and are
loaded with shells to prevent them from being approached.
Materials.— »S'(roH<7, clo^e canvas (sail-cloth) ; rope; cartridge thread; red chalk;
slow-match; loaded shells ; pitch. A composition of 8 parts of saltpetre as it comes
from the refinery, 2 of pulverized sulphur, and 1 of antimony, passed through
sieve No. 2. These materials are mixed in the hands, passed through sieve No. 4,
moistened with l-30th their weight of water, and passed again through the same
sieve.
292 ORDNANCE MANUAL.
Utenbils. — The necessary utensils for prinding and preparing tbo composition :
Wooden pnltrrn, red chalk, 1 pair xherirn, < ,llar neidles, ninlUt, Hmall goiKje of the
calibre of the fire-balls, troop, Uinvd links, 1 wooden mould, 2 wooden drift*, 20
inches long, one of them U inch and the other 2J to 4 inches in diamctur; 2
wooden pint, 4i inches long, the small end the size of a pa])er fuze.
To MARK TiiK SACK. — Miirk out the pieces by means of the imttcrn, and cut
them with the shears; baste two or three thicknesses together, according t) the
strength of the canvas; sew three or more together, enough to make the sack;
leave one end open, forming a mouth for charging; turn the bag to bring the seams
on the inside. The mouth may be made fast to un iron hoop, large enough to
admit the shell, with which the fire-ball is loaded.
To riiKPAUK THK shf.ll. — Charge the shell with j)owdcr and put in a slow fuze.
Dip the tarred link into the melted rosin, pitch and tallow, and fasten it with twine
to the shell around the fuz-e-hole.
To oiiAUGK TIIK SACK. — Placc the sack in the mould and secure the mouth to it.
Put the shell with the tarred link in the bottom of the sack, the fu/.c-holo down-
ward, and fasten the shell down with twine passed through the sides of the sack,
or with a piece of canvas secured to the sides ; put in the composition with a scoop
and ram it, first with the small drift, and, when it is half the height of the projec-
tile, with the large drift, driving it with the mallet. Continue in this way till the
sack is Oiled to the top. Close the mouth of the sack, sewing the pieces together.
TuK luoN BOTTOM. — Thc ball is furnished with an iron bottom, to prevent it from
being broken by the force of the charge in thc mortar. To make the bottom, thc
iron, .'2 inch thick, is cut in a circular form, healed and partly shaped with a set
hammer, in a concave wooden former: it is again heated, and finished in an iron
former. It is then put into a lathe, where thc outer edge is trimmed and chamfered
to thc thickness of i inch.
The iron bottom is attached to the ball witli the cement (page 16^); the bottom is
filled about one-third full with the cement, and the loaded end of the fire-ball i»
inserted in it and left to cool.
The ball is next covered aad strengthened with a net-work made of span-yarn or
cord, from O.'io to 0.5 inch thick, according to the size of the ball. This net-work is
oommeuccd at the bottom of the sack, and terminates at the ti^]! in a strong loop,
which forms a handle for carrying the baU. Fire-balls are dipped in a composition
of equal parts of pitch and rosin, made warm. The ball, when finished, should pass
through the large shell-gauge.
To PRIME THE BALLS. — Make 4 holes, about 3 inches below the top, by driving in
the greased wooden pins 2 inches deep. When the ball is to be primed, lake out
these pins and fill the holes with fuzes, and with two strands of quick-match, held
fast by the composition: leave room in the priming-hole for coiling the quick-matob
and cover it with a piece of canvas fastened with 4 nails.
The balls are not primed until they are to be fired.
SIGNAL ROCKETS. 293
Light-Balls. ^—-rfh
Light-balls are made in the same manner as fire-balls, except that there is no
shell in them, as they are use! for lighting up our own works.
Blue-Lights.
Materials. — For 100 Iff/htn — Saltpetre, 9 lbs. 10 oz. ; mlphnr, 2 lbs. 6i oz.; red
orpimetit, 11 oz. The materials should be pure, well pulverized, and thoroughly-
incorporated, rubbing them in the hands and passing them several times through a
fine hair sieve. Hemiiipherirnl ctipa of well-seasoned wood (beech, linden, etc.) with
a handle 10 inches long, IJ inch diameter; quirk-uialeh, paper, paste.
Utensils. — The necessary utensils for pulverizing and mixing the composition.
PiiEPAiiATiON. — Fill the cup with composition and press it firmly in; prime the
cup with quick-match, and cover the whole with cartridge paper pasted to the
bottom of the cup.
The brilliancy of the light depends on the purity and thorough incorporation of
the materials.
Signal Rockets.
Rockets for signals are composed of a paper case charged with composition, ajoot
filled with ornaments, and a light ulick to give direction.
Rockets are denominated by the interior diameter of the case. The most common
sizes are the .75-inch, 1-inch and 1.5-inch.
TO MAKE THE CASE.
Mateuials. — No. 4 paper ; pasfe ; stroiirj twiue.
Implements. — Aivl; ruler; knife; sdndstone ; rolling bench; press and crank;
choking machine; gauge for the case ; paste brush.
To CUT THE PAPER. — Lay off the paper into rectangles, their width equal to the
length of the case, pricking with the awl the four corners on several sheets at once;
cut them with the knife.
A sheet of No. 4 paper makes two rectangles for a .75-inch or for an inch rocket,
by cutting it parallel to the short or the long side, respectively.
To ROLL THE CASE. — Roll tho rectangle smoothly on the former, pasting the paper
after the first turn ; put the case and former in one of the grooves of the press, and,
by means of tho crank slipped on the square end of the former, turn it; the top" of
the press bearing on it slightly at first Paste tho second rectangle, introduce one
end under the last rectangle, and roll it as at first. Gauge the case, to sec that it is
the size of the mould.
If there be no rocket press at hand, a long hand rolling board may bo used
instead.
To CHOKE THE CASE. — Wrap a piece of strong paper around the end of the case
204 ORDNANCE MANUAL. '
to ltd choked, to prcvcDt the cor'I from chafing it ; take a turn around it with the
ohokiDK-cord, and ])r<-i<H on the treadle, turning the case at the same time, and draw-
injt out the small imrt of the former as the jjaper contracts; make the choke fa«t by
wrapping it i^tveral times with strcmj; twine, drawing it firmly, and tie it in a hard
knot: |ilace the eases uwaj tu dry in the shade.
TO nBIVK THK ROCKKT.
MaTRRIALS. — Empty rimm ; coinjjo'ition ; cliiy or pltnlrr of Parit.
The cum]>ositioD is composed of 26 parts of nitre, .'>} of sulphur, and 19 of
oharooal, which arc mixed hj ruhbing them io the hand, and passing them three
times through the sieve No. 2; the charcoal is added, and mixed with the hands. If
antimony or steel filings be used, they should be added after the charcoal.
When beginning with a new compobition or new materials, it is necessary to try
the composition by firing two or three rockets made of it, ami regulate the height
of the milt'd. If the rockets do not ascend sufficiently high, increase the quantity
of nitre, and diminish it if the rockets burst or blow out the head.
When rockets are well made, they ascend rapidly to a great height, an<I throw
(At their ornaments at the highest point of the curve, after all the composition baa
burned out.
Utensils. — 1 mow/i/and fjiimilr; 1 Uock <»/iror»rf, settled in the ground; 3 koltoie
drift*, bored to admit the spindle; I tolid drift ; m<illeti; kuive* ; §and*lunea ; 1 thnrg-
ing Indlr of such size thai its contents, when driven in the case, shall be a diamet«.-r
in height.
To iMT TDK TASK IX THK Moi i.ii. — In the first jdace, cut off the choke<l end of the
ease square, and to such a length that when the case is settled down on the s[dndle
the choke should fit closely over the nipple, and the end of the case rest on the base
of the 8i>indle.
Place the case on the spindle, the choked end down ; settle it with two or three
blows of the mallet : set the mould over the case and key it down.
Driving the rocket. — Take a ladleful of composition, strike off the surplus and
pour it into the ease. Use first the longest hollow drift, and give each lailleful 25 or
SO blows with the mallet, keeping the drift down on the composition. As the eaae
fills, use the shorter drifts until the composition reaches the top of the spindle; then
drive 1 diameter in height with the solid drift, cover this with a patch of stiff paper
cut to fit the case, and over this patch drive a wad i diameter high, of clay, or of
piaster of Paris slightly moistened with water.
Rockets are sometimes driven solid throughout, and afterward bored and reamed
OBt with a reamer of the form of the spindle.
The mnMldf fi>r driving are not indispensable. Rockets are oft«n driven without
them. For this purpose, screw the spindle vertically into the top of a block of wood
firmly imbedded in the ground. To the opposite sides of this block attach two
upright strips of plnuk. and fasten to them a cross-piece which has near its centre*
hole to fit the rocket-case and keep it steady on the spindle in driving.
SIGNAL ROCKETS. 295
To guard nffnivst arcidrnft, drive rockets in an empty rotim ; particularly, let no
powder be in the room, or composition, except that used at the time, and let no filled
rocket-cases be lying about. In fair weather use a tent for a driving room.
To PRIME THK ROCKET. — Insert in the bore of the rocket one end of a piece of
quick-match, 2 feet long, a small piece of paper attached, and push it in securely;
coil the rest of the match in the bore and bottom of the case. To secure it from
dampness, paste over the end of the case a circular cap of strong paper.
TO MAKE THE POTS.
Materials. — No. 4 paper, pnntc.
IJTENSrLS. — Knife, former, rolling hoard, hotel for pdste, hiushra.
Making the pot, — Cut the rectangle and roll it on the former as described for
port-tire cases.
To attach the pot. — Paste the pot on the inside the di.«tance of one-half of a
diameter, and also the out-^idc? of the case, at the end containing the clay, for the
same length ; slip the pot on the pasted end, leaving the length of the pot above the
top of the case t)ne and a half diameter.
To secure the pot in place and give a neat tinisb, cover the rocket-case and pot,
when dry, with thin paper pasted on.
TO MAKE THE CONES.
Matehials. — iVo. A: jiaper, paste, thin paper.
Utensils. — Compnsse», knife, scissors, conical former, howl for paste, hriishes.
Making cones. — Mark out the No. 4 paper by describing with the compasses
circles with a radius equal to the length of the cone required. Cut them out with
the scissors, and cut each circle into semicircles. Paste each semicircle and roll it
sep.arately on the former; press it firmly, and put it away to dry. Cut the cones to
such length that their bases shall bo of the same diameter as t'lo pot. Make in the
same way a similar cone of thin paper one inch longer, and paste it on the first; cut
the part of the cone formed of one thickness of paper into longitudinal slips \ inch
wide.
To LOAD THE POT AND FIX THE CONE. — Put in the bursting charge of 150 to 300
grains of powder in the bottom of the pot, and fill it with the decorations, placing the
serpents and streamers on end, the primed ends down. Fill the cone with tow, and
paste the strips of the cone; place the cone on the pot, and press the strips on the
side of the pot; paste a narrow baud of paper around the rocket close to the base of
the cone.
The axes of the rocket-case, of the pot, and of the cone, should be in the same line.
To ATTACH THE STICK.— Tie the stick to the rocket, with strong twine or annealed
iron wire from .04 to .08 inch in diameter, at two places : first at the choke of the
case and the second notch in the stick, crossing the ends of the twine under the
stick to prevent its moving to the right or left; the second, in the notch at the end
of the stick and near the pot; tic the twine in a hard knot, and cut the ends close.
296 ORDNANCE MANUAL.
If wire be used, twi»t the ends together with plicrF, jiiid flatten the end« into the
notch.
After the stick is attachp<i, the centre of jfravify of tiie rocket should bo from .8
inch to 2 imhes from the end of the case. aecordinK to the kind of dceorutionc used.
For tiiin inirpouc, if necei<Kary, reduce the size of tlic slick at the end.

WAE POCKETS.
The war rocket used in the military service is made after H.ale's patent. It
consists, 1st. Of a sheet-iron case lined with paper and charged with rocket com-
position. 2d. Of a cast-iron cyliudro-conoidal head, with a small ^cavity commu-
nicating with the bore of the rocket, and pierced with (hree holes, oblique to the
surface, for the escape of gas. 3d. Of a wrought-iron plug welded into the rear
end of the case, and having a hole in its axis for the escape of gas.
The rocket is driven forward by the escape of gas through the hole in the rear
end, and a motion of rotation around its axis is given to it by the esc.-ipe of gas
through the holes in the head, whereby its direction is preserved without the use of
a directing stick.
The composition is pressed solid in the case by means of a powerful press, and
the bore of the rocket is drilled and reamed out to the proper size.
The sizes of rockets are indicated by the interior diameter of thp cases.
The two sizes used are the two-inch and three-inch.
To MAKE THE 3-INCH CASE. — Select the best lap-welded sheet-iron tubing. Cut
it into lengths of 14.4 inches, and weld into one end a ring made of bar-iron 0.625
inch by .25 inch, leaving a hole in the centre of .75 inch diameter. Swage the
ring into a conical shape, the small end 1.6 inch diameter; cut off the ends of the
case square, and ream out the hole to .95 inch diameter.
Ream out the hole in the base of the head to .875 inch, turn and fit the head into
the case, and bore three holes, equidistant from each other, .45 inch diameter,
through the lap of the case and head into the cavity of the latter, the holes in a
plane perpendicular to the axis, but the holes not passing through the axis. Bore
nine holes .18 inch in diameter through the case into the head, for riveting on the
head.
TO DRIVE THE ROCKET.
Composition. — Nitre, 10 parts; sulphnr, 2; charcoal, 3. Place the case in the
mould, put in the case about 3^ oz. of composition, and press it with a pressure of
about 20 tons; continue in the same waj' until the composition is about 1.2 inch

STORAtJE AND PRESERVATION OF AMMUNITION AND FIREW0HK8.
Storehouses and magazines should be kept in the neatest possible order, tb*
stores arranged as much as possible by classes, kinds and calibres, and labelled.
They should be ventilated from time to time, in the middle of the day. in fine
we&ther — particularly those which contain ammunition and fireworks which are
iignred by moisture.
Provide cloth blinds for all windows exposed to the sun.
Leaden BalU are generally kept in cellars, on account of their weight: the boxes
PRESERVATION OF AMMUNITION AND FIREWORKS. 301
should be kept as dry asi possible, and so piled as to admit tbe circulation of air
about them.
Cartridges for small arms are kept in magazines, the barrels or boxes being
piled 3 or 4 tiers high at most.
Fixed Ammunition for Cannon. — If not in boxes, it should be placed in piles
formed of two parallel rows of cartridges, with the sabots together — in 4 tiers for
12-pdr., and 5 for 6-pdr. ; chock the lower tier with strips of wood fastened with
small nails ; put a layer of tow 2 inches thick between the shot ; let the piles rest
on planks, if there be no floor, and cover them with tarpaulins ; have the place
swept, and the cartridge-bags brushed off. Leave a passage of 18 inches between
the double rows, and keep them 2 feet from the walls.
Fixed ammunition should not be put into powder magazines, if it can be avoided;
it should be kept in a dry place, above the ground floor if practicable; the store-
rooms should be always aired in fine weather; the piles should be taken down and
made up again every six months at most, the bags examined and repaired, and the
damaged cartridges broken up. A ti<!ket on each pile should show the number and
kind of cartridges, the additions to the pile, and the issues.
Caniiters. — Piled up like fixed ammunition, in 4 tiers for 24's and IS's ; and 5
for 12's and 6's. Empty caniriters in 10 or 12 tiers; the bottoms and covers separ-
ately.
Cartridfje-hafjK filled. — Like fixed ammunition ; or packed in boxes or barrels.
Cartridge-hags empty. — In bundles of 50, sealed up in paper cases, carefully
closed with strips of thin paper pasted over the #eams.
Paper Cartridge-hngs. — In bundles, packed in boxes or on shelves, in a dry
place, with pounded camphor and black pepper, or tobacco: the flannel bottom
dipped in a solutiun of the sulphate of copper.
Loaded Shells should never be put into magazines, except from absolute neces-
sity ; powder is not well preserved in them. They should be piled on the ground
floor of a secure building — on planks, if the floor be not boarded; in 6 tiers at
most; the fuzes of the lower tier in the vacant spaces between the shells ; those of
the other tiers turned downward, like the fuze-holes of empty shells; the pile
should be covered with a tarpaulin.
Use the same precautions against moisture and accidents as in a powder maga-
zine.
Canister Shot. — Keep them, the different kinds together, in bins or boxes.
Slow-match.— In a dry place, such as a garret, in boxes or barrels, or piled on the
floor.
Quick-match. — If not in boxes, it may be hung up in bundles, on ropes or pins,
and covered with paper.
Friction Primers. — In tin bo.\es.
Port-fires. — Bundles of 10 are placed in boxes or in barrels, on end, in safe and
dry situations.
Fuzes. — Packed in boxes — fuzes of the same kind, as much as possible, in the same
box — in very dry and well ventilated stores. *

another, turns the bag wrong side out, and cleans it. The strapped shot are uken
to the door of the laboratory, where the shot which still require cleaning are sep-
arated from their sabois and immersed in the tub of water: after standing some time,
they are washed and cleaned. The others remain strapped. The serviceable,
reparable, aad unserviceable cartridge-bags are se[.arated from each other; the U«t
are immersed in water, and used for rags. The pieces of twine are tied up in bundle.
The shells are put aside to be unloaded and cleaned in like manner.
The breaking up of fixed ammunition requires many precautions, and should neT«r
be done in the magatine, bot m much as possible in the open air. Never have hot
little powder and a few cartridges in the shop at one time.
ORNAMENTAL FIREWORKS. 303
Canisters. — Turn up the slit ends of the canisters, by means of a small chisel;
take off the cover, and pull out the balls and saw-dust into a bo.\ by means of a hook;
take out the bottom plate, and straighten the cylinder with a mallet on an anvil.
PoRT-FiitES. — Split the paper: take out the composition, and pulverize it by
rolling for two hours. It may be made to burn more or less quickly by adding
mealed powder or sulphur.
Unloading Shells.
This is necessary in order to save room in the storehouses, and to prevent acci-
dents and the deterioration of the powder. It should be performed with great care,
and at a distance from the magazines, storehouses, or dwelling-houses, employing
no more men than are absolutely necessary.
Separate the workmen from each other; jilace them near a ditch or deep hole, into
which they may threw a shell, should it take fire, and thus shelter the men from the
fragments.
Remove the powder frequently as it is taken from the projectiles.
Workmen. — 1 artificer; 1 helper.
Implements. — 1 fuzc-wrruch ; awh; a coil o/ rope, or a block, to place the shell
on ; 1 brace, with bits of the size of the bore of the fuzes ; 1 copper chinel; 1 wooden
drift ; 1 mallet ; 1 copper hook, and rncis, to get out the powder and clean the interior
of the shell; 1 Icnife ; a tub and a basket for the powder and fuzes: a tarpaulin ; a
bucket of water.
For large shelh, in addition to the above: I fiizc-e.rtractor, for mortar shells ; a
pair of shell-hooks and a handspike ; 2 trestles and & frame, to rest the shells on after
extracting the fuze, for the purpose of emptying the shells over the tub.
The helper places the shell on the coil of rope, and holds it firmly in both hands :
the artificer unscrews the fuze with the fuze-wrench. If the shell have a paper
fuze, the artificer thrusts the sharp point of the awl between the fuze and the plugs,
and pries the fuze out; a second awl may be used opposite the first; or cut out the
composition ..3 or .4 inch with a knife, and screw into the pivper case a screw fitting
it closely ; draw out the fuze by means of the screw.
If it be a mortar shell, bore out the composition with a brace and bit, keeping
the composition constantly wet with water ; drive in the bore of the fuze a plug of
hard wood ; screw in the fuze-extractor and draw the fuze.
ORNAMENTAL FIREWORKS.
Ijances.
Lances are small paper cases, .2 to .4 inch diameter, filled with one or more com-
positions, each burning with a fiaine of a particular color. They are used to mark
the outlines of figures, and are attached to light frames of wood, or sticks of
bamboo.
To MAKE THE CASES. — Cut the paper into rectangles, of a length equal to the
o04 ORDNANCB MANUAL.
required length of the case, and of such width us to mukc the case throe thick-
nesses of No. 7 |ia|icr. The leu;;th of the case is poncrally ahout t(;n times its
exterior <liaiiu'ti-r, <ii'pi'iHliup on the composition with wliich it is to be fiUud. and
the time it is rcMjuircd to burn.
Paste the rectangle, and roll it on an iron former with tlic liuml. When the cases
are dry. cut them to their projtcr length.
To iiiiivK TUB LANCK. — Place the cases in holes bored in a block of liar<l wood,
the holes .02 inch larger than the case, and their depth .26 inch less than the length
of the cHsc.
Drive in the bottom of each case a ladleful of clnv. Insert in the top of the
case a small funnel; pass the drift through the funnel into flio rase: fill the funnel
with composition ; raise the drift I inch above the to)) of the cast; press it to the
bottom, and give it three light blows with a rocket-drift ; coctinuo in the same
way, raising the drift above the top of the case between carh rollry, until the caM
is filled to .25 inch of the t«p.
Prime the lance with mealed pi'wd»r moistened with gummed water, and dip the
end while moist in rifle powder.
When the cose is to be filled with two different rompusilions, drive the case with
the first composition till it is about .2 inch above the rci{uired height; remove the
Rurplus (o the exact height with a gauge, and proceed with the second composition
as with the first.
To FASTKN THE LANCKS TO THE KRAMB. — Hore bolcs .02 inch Inrger than the
lances, and .6 inch deep, from 2 to 4 inches apart, according to the size of lance.
The holes should be bored so that the lance shall bo horizontal when the frame is
in position. Dip the end of the lance in glue, and ]iress it firmly in the bole,
arranging the lauces parallel to each other. Or they may be fastened to the frame
by means of sharp nails or tacks driven into the frame and projecting about .4 inch.
The end of the lance is pierced with an awl, di]>ped in glue and thrust on the point
of the nail, arranging them {>erpeudicular to the frame.
Sun-Ciises.
•
Sun-cases arc strong cases made like those for rockets, and filled with ft eonip»>
sition which burns more slowly than rocket composition. They are attached to
wooden frames, to give long rays of sparkling light. The choke is sometimes
made by driving clay in the end of the case, and boring a hole through it for the
escape of the flame ; or the clay is driven on a short nipple, forming the choke.
Sun-coses are generally ma<le from .75 inch to 1.6 inch interior diameter; their
exterior diameter about double that of the interior. The length of the ease may
Tary according to the time they are required to bum.
The diameter of the choke is about i the interior diameter.
To MAKE TUB CASES. — The cascs are made like rocket-cases.
To DRIVE THE CASE. — Set the case on the nipple and place it in a wooden moald;
ROCKETS. 305
pour in a ladlcful of compoeition, and give it tea blows with the mallet; continue
in the same way till the case is filled to the required height: put in a charge of
rifle powder, and over it drive a ladleful of clay.
When the cases are filled, prime them by inserting in the choke a strand of
quick-match, doubled in the middle and secured by driving a little composition on
it with a lance-drift.
Paste on each end of the case a strip of paper 5 inches wide, projectino' 3 inches
over the end of the ease and forming an envelope to enclose the leaders.
Sun-cases are fastened to the frames in the plane of the frame, by means of iron
wire, or with strong twiue.
Lights.
Lights are made by pressing lance or similar composition in shallow vessels, or
in cases of large diameter. The b'urning surface being large, the light attains a
great intensity.
Shallow earthen, wooden, or metal vases, or paper cases, are used. The vase or
case is filled with dry composition, slighty pressed in ; or composition moistened
with gummed water may be used and pressed in the case more compactly. It is
primed by powdering the surface first with a mixture of equal parts of the compo-
sition and mealed powder, and then with powder alone. Cover the top over with
paper, pasted on the sides of the case. Through the centre of the cover pass sev-
eral strands of quick-match, spreading them over the surface and uniting them on
the exterior in a single strand.
When the light is made with dry composition, the case must be placed in a ver-
tical position. It may be placed horizontally if moistened composition be used
and firmly packed.
Torch-lirjhts for funeral ceremonies are made by impregnating large strands of
cotton with a thin alcoholic pap, the whole arranged in vases like an oil lamp, the
pap replacing the oil.
Petards.
Petards are small paper cases filled with powder. One end is entirely closed,
and the other has only a small hole left for a piece of quick-match, to communicate
fire to the powder. Petards are placed at the bottom of lances ; they are also used
to imitate the fire of musketry.
Rockets.
Rockets are made and driven as described for signal rockets (see page 293),
except that diflferent compositions are used, giving a more brilliant train of fire.
Rockets may be made of all sizes : their general dimensions may be deduced
from those given.
Generally, in proportion as the size of the rocket is increased, the thickness of
the case must be increased, and the bore of the rocket diminished, or the qujckness
of the composition, or both of them.

■amo time thnt it revolves horizontally around its mid<llc point. It hax light winga
attached tu it, to direct it« mutioq.
Shells.
Shells arc made of lij^ht wood or paper, and filled with ornaments of diflereat
kinds. They are thrown nearly vertionlly from a mortar, and, when at their
highest point, explode and throw out their urn)imenti<, set on Ore by the bursting
charge.
To MAKR TUB KHRLL. — Turn in a lathe, from well seasoned poplar or pine, two
bemi^pheres of the sire and thickness re<|uired. leaving a rabbet to unite the two.
Cover the slull thun formed with len« chaped pieceK of No. 2 paper, pasted on
•mootlily, two ..r three thicknei^ses : or form the shell on a ball the sixe of the earlty
of the shell, by paoting on it strips of pajier of lens sha[>e until it is .2 inch tbiek.
Cot the shell into two e<(ual parts and take out the eore ; place ihr two halvw
together, and continue to parte on pieces of paper, permittinit them to dry perfectly,
until the shell is of the required thickness. This inMlc requires much lime, aa IIm
■bells dry slowly, and each successive layer mut>l be thoroughly dry before olb«r
pieces are |iasicd on.
To CIIAHOK THK SHELL. — Introduce the staro, scri>enl», ete., through the AiM«
hole, and then the bursting charge ; cover the fuse where it cornea iu contact with
the shell witL glue, and drive it in place.
To insure the fute taking fire, tic arouml the shell two |>iec«s of (|uiek-ou(ah,
crossing over the fuxc.
Cover the fure with several strips of pai)er pasted to th« shell at their ends.
These are removetl before the shell is fired.
Stars.
The stars for shells are made as described pa^^e 296. Those made of composition
which burn with difficulty mu^t have a hole in their axes, like those uaed for Roman
oandles.
Wheel -Cases.
Wheel-caaes are made and driven like sun-cases. They are used to give • rotary
motion to pieces mounted on an axis, and to produce at the same time a brilliant
fire. They are attached to the end of the spoke of the wheel which they are to lurn
hj means of iron wire, or strong twine, and they are inclined to the spoke from 2U^
to 30° to give a larger circle of fire.
PREPARATION OF COLORED FIRES. 307
Boman CmuJIes.
The Koman candle is a long and strong tube charged with stars, which are thrown
out successively by a charge of powder placed under each star.
The ends of gun barrels, 20 inches long, are used for cases. When pajier cases
are used, make them about .65 to .7 interior diameter and 1 inch exterior diameter:
roll them like port-fire cases.
Three drifts, of different lengths, are used; they are made of hickory' or other
hard wood, with brass tips on the lower ends.
To CHARGE THE CASE. — Put in the case a ladlcful of clay, and drive it w^ith ten
blows of the mallet; then a ladleful of composition, which is driven in the same
way; next a charger of powder and a star, which iy gently pressed down; then
another ladleful of composition, a second charger of powder, and another star —
driving the composition and pressing down the star gently; continue until the ten
stars arc in, and add a half ladleful of composition.
Prime the candle with a strand of quick-match 6 inches long, held in place
against the side of the case b3' a little composition driven in on its ends. Cover
the end of the candle with a strip of paper pasted on.
Roman candles are inserted in holes bored in frames, or tied with wire or twine
in the direction in which they are to throw their stars. The stars used for Roman
candles have a hole through their axes, communicating the fire to the charge below,
which throws it out.
Leaders.
Leaders are long paper tubes of small diameter, enclosing a strand of quick-
match. They are used to communicate fire rapidly from one point to another.
The velocity of combustion is from 1 to 2 yards per second, depending upon the
size of the tube, being more rapid as the tube is smaller.
Leaders are made by rolling a strip of thin paper, 2.5 inches wide, as obliquely
as possible, on a ramrod: or cut the paper into trapezoids, 4 inches wide at one
base and 21 at the other: paste the edges of the strips .25 inch, and roll them on a
ramrod so that one end shall be enlarged, funnel-shape. When dry, pass a strand
of quick-match through, and let it project about an inch at each end.
To unite them into a long line, insert the end of one into another a distance of
.75 inch, and tie them with a thread.
If the line be long, first stretch a piece of twine, and attach the leader to it
every few feet.
Preparation of Colored Fires.
The materials for colored fires should be as pure a,s can be obtained : those which
crystallize should be procured in the crystalline state. They should be generally
first dried, ground fine, weighed out and mixed. The composition is then moist-
ened and pressed into shape. Some of the materials, such as the flowers of sulphur
and lampblack, ought to be first well washed in warm water. Antimony, glass and
copper filings ought, as well as other materials, to be passed through sieve No. 1.
809' ORDNANCE MANUAL.
DnriMO. — All materials fIiouM he perfectly dry. Those which contain water of
crystiilliiafmn, b." the iiitriile of Imrvfn. iiilr.ite of strontia, and sulphate of copper
■hoiiM have it <lrivcn off. For thi.' purposo, place the suit in a hrouil, dhallow vesael
ill a waler-hiilh or on a moderate Cro and stir it till it bo perfectly dry, takinj; it off
the fire gome minutcD before.
An the tiiili>hntc of copper is easily' ilccomposed in this operation, and as the sul-
phuric aci<l set free mi^^ht occasion a spontaneous explosion when the sulphate of
copper was liroiight in contact with the chlorates, two parts of li(|uid ammonia arc
(lourtil by de;;rcc8 on the sulphate of copper powdered and yet hot. (The ain>
uioiiia iiculraliics the acid, and, instead of injuring the color, it heigliteoa it. The
same proccus should be adopted with other decomposable metallic salts.) A thick
li>|iiid of an indigo blue color is obtained: place it od the fire, and warm it gentlj
until it becomes a thick pa^te: then, leaving only a few coals under it, stir it with k
spatula and crush it into a powder.
GiiiNDiN'O. — The materials are ground in a mortar with a pestle, or on a lier*
with copper balls 0.4 inch in diameter, of equal weight with the composition to b«
ground. All the utensils shi>uld be kept perfectly clean.
To ])ulverize antimony, melt it and pour it into a cast-iron mortar preriuuily
warmed: when the metal is on the point of congealing, stir it briskly with the
]iest]o: it is thu!< reduced to fine grains, which are then pulvcriicd with a pestle.
Zinc aud other similar metals arc treated in the same way.
To obtain shidlac in the slate of a fine powder, it is first broken into pieces and
melted with its weiglit of saltpetre The mass is then ground as usual, and the
powiler thus obtaiiie<l is washed in pure water till all the saltj>ctre is removed.
The resins and other substance." insoluble in water and difficult to pulverize In
their pure state are treated in the same manner.
All materials when pulvcriicd should be passctl through hair sieve No. 1. They
ought, if possible, to be sifted when warm, and placed away immediately in well
stopped bottles to preserve them from moisture.
The chlorates should be pulverized in a marble mortar with a hard wood pestle.
The mortar, pestle and sieve should be used only for a single chlorate, and the
whole operation be performed in a jdnce apart, to avoid accidents. The chlorate
can be ground and manipulated by itself without danger; but when it is mixed
with sulphur, charcoal, etc.. it explodes very readily.
Wki«bin6. — Each material should bo weighed accurately by itself, according to
the proportions laid down in the table.
Mixing. — The materials after being weighed out are poured on a sheet of paste-
board and mixed as well as possible with the hand: they are then passed three
times through sieve No. 2, keeping the sieve stationary, and stirring the materiala
with the hand.
If a chlorate enter into the composition, begin by mixing all the materials, on a
pasteboard, except the sulphur, charcoal, lampblack, sugar, tallow aud shellac
Whou they are well mixed, add the combustible materials separately, mix
thoroughly, and theu add the chlorate.'
SIEVES. 309
Pass the composition three times through sieve No. 2, using a feather for the
purpose.
All these manipulations with compositions into which a chlorate enters should be
pcrformetl in a place aside, and with a small quantity at a time.
Compositions thus prepared should be preserved in well stopped bottles, carefully
labelled. Those containing chlorates should be placed away from the rest and
apart from each other.
Dampening. — Compositions are dampened by pouring the pure or gummed liquid
on them, a little at a time, and mixing it well with the hand or a wooden knife.
Compositions should not be dampened until just before they are to be moulded.
Moulding. — All compositions may be firmlj^ comjiressed. provided care be taken
to avoid friction and blows with those containing chlorates.
However great the care taken in the choice of materials, their proportions and
manipulations, it is difficult always to get uniform results. It is necessary, there-
fore, to try the mixtures and modify the proportions as may be required.
In every composition there are certain substances which are used to furnish
oxygen for the consumption of the rest : the nitrates and chlorates are such. There
are other substances, as sulphur, charcoal and vegetable matters, which are burned ;
and others which are only used to give c(jlor to the flame, as antimony, lead, cop-
per, strontia, etc.
The same substance may furnish oxygen and color the flame at the same time.
Certain materials are used onlj' to heighten the color — as the protochloride of mer-
cury and the hydrochlorate of ammonia : the action of the latter is weaker than
that of the former.
When a composition burns too slowly, there is an excess of coloring matter or of
that which is to be burned, or some other substanqe (as water, for example) — very
rarely of that which furnishes oxygen. When the composition burns too fast, it is
necessary to add coloring matter, or such substances as sugar, rosin or tallow,
which operate by separating the substances supplying the oxygen from those which
are burned, and at the same time keeping up the combustion.
Generally, the quicker the combustion the more will the flame approach to white-
ness, whatever may be the coloring principle, and the slower the combustion the
more certainty there will be of obtaining the desired color.
Sieves.
Sieves are made of brass wire, hair or silk, and may be square or round in shape.
I^No 1 \^^ meshes in 1 inch, or 2,500 in a square inch,

FIELD TRAIN.
Ordnance.
The proportion of artillery to other troops varies generally between the limits of
1 and ;^ pieces to 1,000 men, aceording to the force of the array, the character of the
troops of which it is composed, the force and character of the enemy, the nature of
the country which is to he the theatre of war, and the character and objects of the
war.
Similar considerations must regulate the selection of the kinds of ordnance and
the proportions of the different kinds in the train.
The following principles may be observed in ordinary cases:

200 rounds to each piece, both of the reserves and of the active batteries.
The ammunition which cannot be carried in the caissons attached to the pieces
will be kept in bo.\es with the reserves.
Additional supplies of ordnance and ordnance stores are placed in convenient
depots, according to circumstances.
Ammunition for Small Arms.
100 rounds to e.ach man ; of which, for the musket, 40 rounds are in the c.artridge-
bo.K, 60 in the parks of reserve. In the same proportion for other small arms.

Such additional supplies of the above kinds as may be thought necessary will be
carried with the park of ^reserve, together with the necessary ammunition for
infantry, in jiacks.
A mountain howitzer ammunition-chest will carry about 700 musket ball
cartridges.
Rocket Battery.
No regular organization of a rocket battery has been arranged.
The nature and number of rockets, and of carriages or conductors, will be deter-
mined by the character of the service for which they may be required.
The Field Park.
The spare carriages, reserved supplies of ammunition, tools and materials for
extensive repairs, and for making up ammunition, for the service of an army
in the field, form the Field Park, to which should be attached also the batteries of
reserve.
The quantities of these supplies must depend in a great measure on the particular
circumstances of the campaign.
The ammunition required for artillery and small arms (according to the propor-
tions above stated), in addition to what can be carried by the batteries and the
troops, will be carried with the park, in caissons or in store-wagons.
The following carriages and stores, in due proportion, according to circumstances,
will also form parts of the field park, viz :

SiMTLK KNOT. — Form a balf-Litch: turn one end arouml the other, pMsing it
tbroufth the half-hit<h : close it by drawing the two ends.
SiMiM E URAW-KNoT, or Bow-K.NOT. — Form a half-hitch; make a loop with one end;
tarn this loop around the other part, t^o as to pass it in the half-hitch; close iu
Gai.i.ry knot. — Form a simple draw-knot ; pass a lever in the loop, and close it.
Sgi'ARK KNOT. — 1«» Mrthod : Cfoss the ends of the rope, say, the right end over
the left; turn the left end around the right branch from above downward, and from
within outward ; bend the left end. forming a loop with it : turn the right end around
the left, and pass it in the loop from below upward; close iL
id Mrih<i<i : Make a loop with one end; pa^s the other end through the loop, and
take a turn around the two branches that form the loop, beginning with the long
one; pass it again through the loop, and close it.
That the knot may not slip, the two ends of the rope should separate, one to the
right, the other to the left, but both in front or both behind.
Draw st^iARE knot. — Make an onlin.iry square knot, but with the end passed in
the loop to complete the knot ; form a second loop, and pass it through the first ;
close it.
Weavers' knot. — Form a loop with one end ; pass the other end through the
loop, and take a turn around the two branches forming the loop — first around the
long one — and pass it between the loop and that part already passed through the
loop ; close it.
KNOTS, AND THE MANNER OF TYING THEM.
359
Gkrman knot.— Form a half-bitch ; turn the free end around the standing part;
cross the free end on itself, and pass it through the half-hitch.
Artificers' knot, or two half-hitches.— l»r J/ef/joc/ .• Make two half-hitches
near to each other, but in contrary directions ; that is, if the free end of one half-
hitch cross above that part of the rope which is between the half-hitches, the free
part of the other half-hitch must cross under,- place these two half-hitches one on
the other, so that the ends shall be on the inside; put the half-hitches over the end
of the object to which the rope is to be fastened, and close it.
2d Method : To fasten a rope to a picket, keeping it stretched, take a turn around
the picket with the free end, and bring it back under the standing part ; take a
second turn above the first with the same end, passing the free end between the last
turn and the fixed part; close it by drawing on the free end.
3d Method i Form a half-hitch, with the free end beneath ; place it over the head
of the picket; form a second half-hitch, the free end beneath; place it over the
picket, above the first; close it.
Magnus hitch.— Take a turn around the picket with the free end, and bring it
back above the standing part; take a second turn with the same end, and bring it
back under the standing part: make with this end a half-hitch, the free end
being underneath ; place this half-hitch over the picket ; close it by drawing on
the free end.
This knot difi'ers from the artificers' knot, by having three turns around the
picket, instead of two.
M00F.ING knot, with half-hitches.— To fasten a rope to a picket by half-
hitches, take two turns around the picket, and bring the free end back along the
standing part; take a turn with the free end around the standing part, and pass it
through the half-bitch thus formed; make a second half-hitch by crossing the free
end aeain over the standing part, and passing the free end through the half-hitch;
tie the end to the standing part with lashing-cord, if necessary.
Rolling hitch.— To tie a rope to another which is stretched, cross the end of the
free rope on the stretched one, and take a turn around it from above downward, and
bring back this end in the acute angle formed by the two ropes; take a second turn
in the same manner; make a half-hitch with the free end around the stretched rope,
and then a second half-hitch above the turns already formed; tie the end to the
rope with lashing-cord.
Anchor knot.— To fasten a rope to a ring, pass the rope through the ring twice;
make a half-hitch around the standing part and the part forming the second turn ;
make a second half-hitch below the first ; tie the short end to the standing part, if
necessary.
Capstan knot.— To fasten the gin-fall, for instance, to the handles of a gun,
make a half-hitch by crossing the free end on the part coming from the head of the
gin; pass the free end through the handles and through the hiiH-hitch from beneath
upward; pass the end around the standing part, turning it between the standing

part and the part leading to tht- handle ; pass it in the loop from shore downward;
draw it clo»c.
CaoW!f.— Take the r»\>u and form a coil of the sire rcrjuircd. and with the fr««
end wrap the tcveral vtriindH forming the coil, and faften the two end* lij a («|uare
knot.
Shout si-Lirn.— Unlny wh.iut one foot of the endn of the two rop«g, A and Bt
that are to lie Hpliocd; bring the end* together, no that the iilran<lii of one rop«
ihHll lie hotwcen lho»e of the other. Holding the rope A in the left hand, for
instance, croM caeh utrand of thif rope over the ^trnnd of the other that in to lt«
lefU and ]>u.r* earh utrand of the rope A, hy meant of a marline-npike, onder th«
Mrand H to the left of that which it crossed; draw hard on ea<>h utrand ihos
tmtii; do the came thing with the strand* of the rope B. To give i;reater
strength to the uplioe, paas again each strand over that t« it* left aiid under the
one Id the left of Uiis last : cut off the projecting ends. Thin splice will not paat
through the throat of the pulley.
LoNO RPi.icR. — I'lilay ahoui QO inrhcc of each rope: bring them together aa in
the short splice: unlay one of the strands of A, and replace it by the corresponding
strand of B; cross the end of this last strand over the replaced strand, and p«W
them, each on its own side, under the adjoining strands; replace, in same way.eaeh
strand of one rope hy one of the other, and secure them two and twn, as haa Jut
been oxplaine<l, at different places in the splice; eat off the projecting ends. Til*
long .-plicc will pans through the throat of the pulley.
To Slew a Gun.
Chock the gun on the side to which it is to be turned; pass a trannion-looa am
one of the trunuioun, run a handspike through it, and turn the gun in ita pla«e.
To Move a Gun by Rolling it.
Place a skid under the middle of the reinforce, and another under the middle of
the chase, and roll the gun over.
By inclining the skids and cutting the muzzle, it may be mored in different
directions.
In rolling heavy guns, it is most convenient to use two collars of wood or caat-
iron, of eijual diameters (one on th» breech, the other on the maztlej, large enonrh
to allow the trunnions to tarn without striking the ground.
To Transport a Field Piece by means of a Limber.
Detach the jirolonge; place the limber over the jiiece, so that the pintle-bonk
shall be over the handles (or over the rear of the trunnions), with the brciooh
toward the pole : run a handnpike into the bore and raise the chaae; Usb the pioon

sSF
through the handles (or around the piece in rear of the trunnions) and over the
pintle-hook.
With the loose end of the prolonp;e. lash the eascahle to tbc fork of the limber.
The gun may he placed on blocks at the proper height, and then lashed to the
limber as before.
To Shift a Gun from the Trunnion-holes to its Travelling-bed.
Limber up ; remove the eap-squares and chock the wheels fr<vnt and rear; place
the short roller under the reinforce: att;ich the trace-rope at its middle to the cas-
cable by two balf-hitehcs; cross two handspikes under the one in the bore; lift and
push at the muzzle and haul on the rope until the trunnions arc over their travel-
ling position ; raise the chase, bring forward the roller to the head of the stock, and
lower the chase upon it; raise the chase again ; remove the roller, and lower the
chase upon the stock ; take off the rope ; replace the cap-squares ; insert the elevat-
ing-screw from below, and lash it.
With the Li/tiiicf-.Jack. — Place the jack under the swell of the muzzle; raise the
chase; place a half block on the head of the stock; take a second lift, and place
two rollers on the stock, one just in rear of the trunnion, the other under the rein-
force; chock the latter toward the muzzle, and remove the half blocks: haul on
the rope attached to the cascable, and bring the breech over the bolster; chock the
rear roller; place the jack under the muzzle, and remove the rollers.
To Shift a Gun from, its Trdvelling-bed to the Trunnion-holes.
Chock the wheels front and rear; remove the cap-squares: raise the chase and
insert the short roller under the trunnions ; attach the rope by its middle to the
cascable ; bear down the muzzle, *nd, as the piece rolls forward, guide the trun-
Tiions into their holes bj' means of the rope ; remove the short roller.
A howitzer is shifted to and from its travelling-bed by the same means, except
that the handspike in the bore is chocked above and below for raising the chase,
the lower chock being placed about 18 inches in the bore. The vertical diameter of
the short roller should be just forward of the rimbases.

Raiiio the pry-pole ; run one end of the fall through the left sheave from holow :
\ta,** it through the pully which is hooked to the miildlo brace, and thence through
the right sheave, securing it to the pully or to the middle brace.
To Raise the Field Gin.
Odc man places his foot on the lower brace, holds the foet of the gin in place, and
■toadies the pry-polo. Six men seize the logs and raise the gin.
To Move the Field Gin when Raised.
Place four men at the ends of two handspikes run under the windlass, apd two
men nt the handles of the pry-pole, and move the gin. The gin is lowered in ft
manner similar to that prescribed for raising it.
To Put a Casemate or Garrison Gin together.
The legs or pry-p<>le are laid on the ground or acroM the gun-carringc, inner
■ides down and upper ends together, to receive the clevis and bolt. The windlus,
braces, and clevis uud bolt aVe then put in their proper places and secured. The
gin is then raised by moving up the legs and pry-]iole toward each other.
To Reeve the Fall of a Casemate or Garrison Gin.
Fasten one end of the trace-rope to the upper block, pass the other end through
the clevis, and thence round the windlass. Ilcave upon the windlass, raii<e the
block, ami hook it iu the clevis. Reeve the fall as described for the field gin.
To Lower the Casemate or Garrison Gin.
Draw out gradually the legs and pry-pole until the men can get n«Ar cnongb to
the head to support it. Lower it upon the piece or upon the ground.
To Move the Casemate or Garrison Gin.
Lash the pry-pole to the upper brace to keep the gin from spreading. Four men
lay hold of each leg and move them ; then move the pry-pole.
To Mount a Piece by means of a Gin.
Place the gin with its pulleys directly over the trunnions, and the foot of the pry-
pole about thirteen feet from the lower brace. Remove the cap-sqaares. run a haad-
spikc into the bore, fasten the sling to it and over the cascable, and hook the pulley

to it, just in rear of the trunnions. Steady the gun with the handspike in the bore,
pass the running end of the fall from the outside under the windlass, and take three
turns with it from the right to the left around the left of the windlass, and hold fast
to the end of the rope. Work the windlass and raise the gun to the required height.
Bring up the carriage until the trunnion-holes are directly under the trunnions.
Slack off the fall slowly, and let the trunnions descend into their holes. Put on the
cap-squares.
IlE>f ARK. — The piece may be slung with a short piece of rope passed around each
trunnion, and the ends fastened together on the top of the piece ; or the trunnion-
rings may be put on. Ilook the pulley to this sling, or to the trunnion-rings, bear
down with one or two men on the handspikes in the bore to balance the piece, and
raise it to the proper height. Place a handspike in the trunnion-holes, and a block
on the stock to receive the breech. Lower the gun, the trunnions directly over the
trunnion-holes, until it rests upon the handspike. Remove the sling from the trun-
nions, and run the carriage, with the gun on it, back until the heads of the cheeks
are in rear of a perpendicular let fall from the head of the gin. Pass the sling
around the chase, hook the pulley to it, and work the gin to relieve the weight on the
handspike. Remove it, and lower the trunnions into their places. Bear down the
muzzle, and remove the block from under the breech.
To Dismount a Piece by means of a Gin.
Place the gin as for mounting the gun, remove the cap-squares, put on the sling,
raise the gun out of the trunnion-holes, run out the carriage, and slack off gradually
to lower the gun to the ground.
To Shift the Fall.
Overhaul the loose end of the fall, and make a double hitch with it around the leg
of the gin below the lower cross-bar, passing the end inside of the windlass and
braces to a man mounted on the windlass, who makes with it a rolling hitch on the
standing part of the fall near the upper brace. Slack off until the weight bears on
the end of the fall, and slip the rope to the other end of the windlass; or the stand-
ing part of the fall may be lashed to the leg above the windlass with a small rope.
To Mount a Gun on a Casemate Cdrriage.
Traverse the carriage to one side; place the gun on blocks, or on the truck, near
the middle of the casemate, the muzzle toward the embrasure, and the gin over the
gun and carriage; the latter on the side of the pry-pole. Sling the gun, and work
the giu until the gun is raised sufficiently high to traverse the chassis under it; jdace
the carriage so that the trunnion-holes come exactly under the trunnions ; lower the
gun into its place ; remove the sling, and take away the gin.
To prevent the pavement from being injured by the points, a truck-wheel, or a
piece of 3-inch plank, with a hole to receive the point, is placed under each foot.
To dismount a piece, proceed in the inverse manner.

' To Sling a Gun, Howitzer, or Mortar on the Cart.
Baok tlie cart over the iiiece, the pole toward the breech, and the axle-tree
directly over the trunnions: chock the wheels. Fasten the middle of the prolonge
to the end of the pole, and carry one end of it to the rear of the cart ; raise the
pole l>y hand and by means of the prolonge until it is nearly vertical, and steady it.
Lay the middle of the slinjr-chain over the piece; carry each end around the trun-
nions, from the rear to the front, and hook them to the axle-hooks, being careful to
take uj) all the slack. Haul upon the prolonge until the end of the pole can be
reached by hand ; sciz.e and bear it to the ground ; hook the caseable-chain around
th(k cascable in such a manner that the piece will swing level when the pole is
horizontal. Raise the pole until it rests on the pole-prop. By putting blocks
under the piece, and repeating the operation, the piece may be raised higher.
To Lower the Piece.
'■ Bear the cud of the pole to the ground ; unhook the cascable-chain, and allow
the pole to rise gently until it is nearly vertical. If the piece do not rest upon the
ground, it must be blocked up and unslung. The operation is repeated and the
piece is lowered to the ground. Ease the pole down carefully.
To Sling a Mortar Mounted on its Bed.
Back the sling-cart over the mortar, the pole toward the breech, and the axle-
tree directly over tho trunnions : raise the pole vertically ; pass the sling-chain
around the front manoeuvring-bolts ; hook it over the axle-hooks, and haul down the
pole. Block up the front of the bed ; take off the sling-chain, and pass it under
the bed just in front of the cap-square bolts; bear the pole down to the ground;
remove the blocks ; pass another sling-chain around the rear manoeuvring-bolts and
over the pole, and hook it iu such a manner that the bed will be level when the pole
rests on the pole-prop.
Sea-coast mortars and their beds must be slung separately. The sling-chain is
passed through ihe clevis of the mortar and over the axle-tree, and hooked around
the pole at its junction with the axle, the pole having been raised vertically.
To Sling a- Piece on Two Limbers so that it may be transported
with horses.
Place blocks under tho chase and reinforce : remove the pole of one of tho lim-
bers, and run it over the piece until the pintle is over the knob of the cascable;
raise the muzzle and slip the front block under the trunnions ; bear down the muz-
zle, and fasten tho pintle to the cascable with the chain or lashing-rope ; bear down
the fork to the piece and lash it around tho reinforce. Back the other limber over
the neck of tho piece; raise the pole, and attach the neck to the limber by taking

To Mount a Gun on an Iron Carriage.
A Hiinjtlc and expeditious method of mounting a gun upon an iron eatemate
carriage ronsi!<tH in rnicing the gun upon two scaffoldH, and asRcmhling the chMsU
and top ciirriage in portion under the gun.
Tn do (hii>, place the gun with its muzzle toward the eml>rai>urc and its axis per-
pendicular to the middle of the face of the wall; raise the muzzle and the hrecch
alternately by mean* of the lifting-jack, 8up|n»rting the gun on two scaffold* of
blocks, placed in front and iu rear of the trunnions : acsemhle the chassis in
position; |il»co one cheek of the top carriage on the chassis-rail, with the trunnion-
bole directly under the trunnion, and bolt the transoms to it; ]ilaco the other chock
in ]iositioii, and bolt it to the transoms. Lower the trunnions into their holes, and
remove the blocks.
The lilooks for the scaffolds should be about three inches shorter than the distance
between the rimbasis of the gun, and not less than fifteen inches wide. They
should be two inchch, four inches, and eight inches thick- Neither the muszle nor
the breech should lie raised more than four inches by a sin;:le lift. As soon as the
gun hut' been raised high enough to allow it, the chassis should bo put in place and
assembled. Cari- must be taken to build the scaffolds so as not to let them interfere
with the transoms iu assembling the carriage.
To Dismount the Gun.
Rai^e the breech an<l build a scaffold under it, as in mounting the gun ; raise
the muzzle with a jack, and build a scaffold under the chase; take the cheeks
apart and remove them ; lower the gun until its under surface is nearly down to the
chassis; take the chassis apart, remoro it, and lower the gun upon two blocks.
To Mount or Dismount a lb-inch Gun.
Place the chassis on the platform, and roll the gun on skids upon it, placing
the axis of the gun in the vertical plane of the axis of the chassis. Place u gin
over the muzzle and another over the case-able, and, by means of them and the
lifting-jack, raise the muzzle and the breech, alternately, supporting them upon
scaffolds. When the gun has been raised to the proper height, place the cheeks of
the top carriage upon the chassis-rails, and proceed as in mounting a smaller gun.
To dismount a gun, proceed in the inverse manner.

Chapter Thirteenth
AUTILLEEY PRACTICE.
The plan of this work does not include the details relative to the service of
artillery ; but, in the absence of more full and accurate tables of firing, it is thought
useful to give here the mean results of such trials of the ranges of our ordnance as
have been made from time to time by the Ordnance Department, together with some
other practical information derived from authentic sources.
Ranges.
The range of a shot or shell is the first graze of the ball on horizontal ground,
the piece being mounted on its appropriate carriage.
The range of a spherical-case shot is the distance at which the shot bursts near
the ground, in the time given ; thus showing the elevation and the length of fuze
required for certain distances.

By multiplying the penetrations in the table for masonry by 1.25, 1.75, or 0.46,
tbc penetration in masonry of medium quality, or of brick, or in hard, calcareous
stone (solid), respectively, will be obtained.
Multiply the penetration in oak by 1..3 for the penetration in elm, by 1.8 for white
jiinc. and by 2 for poplar.
Multiply the penetration iu compact earth by O.G.'i for the penetration in sand
mixed with gravel.
By 0.87, for earth mi.x:ed with sand and gravel, twice the weight of water.
" ].09, for compact mould and fresh earth mi.xed with sand, or half clay.
" 1.44, for wet potters' clay.
" 1.50, for light earth, settled.
" 1.90, for light earth, fresh.
In general, sand, sandy earth mi.xed with gravel or small stones, chalk, and tufa,
resist shot better tliau the productive eartlis, or clay, or earth that retains water.
According to the experiments, the holes made in masonry, such as that referred
to in the table, by shot striking it perpendicularly at a short dLsitanee, are formed of
an exterior funnel-.shaped opening, the mean diameter of which is about 5 times
that of the shot, and of au interior part nearly cylindrical. The exterior cone
appears to be produced by the reaction of the masonry, some fragments of which
are projected backward to the distance of 45 or 50 yards. The train of fragments
in front of the bole extends about 20 feet. Around the exterior opening the masonry
is loosened to a distance a'bout one-half greater than the diameter of the opening —
say 45 inches by the 24-pdr. shot, 35.5 inches by the 16-pdr., .31.5 inches by the
12-pdr. This loosening indicates the proper distance between the first shots from
a breaching battery. Nearly all the shot are broken, even at the charge of one-
fourth, and the fracture is generally in meridional planes, the pole of which is the
point which strikes first. On the shot which are not broken, and on the fragments
of those which are broken, small cracks or furrows, sometimes 0.02 inch deep, are
observed, radiating from the same point.
The eUcct of shells fired horizontally against masonry is very small ; they are
382
ORDNANCE MANUAL.
broken at the moment of striking, or if fired wilh very 1"W i-liarpe* so as not to
brcitk, they produce a very slight imprci'sion.
In oak, the fibres arc displaced laterally by the passapo of the shot, and after-
ward cloce up u;ri>in, so as to leave an oj»ening seareely sufficient for measuring the
dci)fh of penetration. This effect explains the cause of vessels not being always
sunk by shot striking below the water-line ; but the timber is split longitudinally
even by the smallest shot, to a length of 6.5 feet; the splinters are driven to the
dislaneo of 42 to 60 feet, and the largest timbers are soon destroyed.
In white pine, nearly all the fibres struck by the shot are broken, but the effeot
does not cxlcud much beyond the opening made: this material is, therefore, prefer-
able to oak fur structures which are not intended to bo proof against cannon-shot.
Penttration in Fascines, Wool, etc.
At the distance of 24 yards, a musket round ball penetrates 20 inches into •
gabion stuffed with sap fagots; the ball from a wall-]iiece, 23. A3 inches. The re-
sistance of faseiues ducrvabcs very rapidly by the twigs being broken or separated
by the balls.
A ivHiiKj gabivn, ."luffed with fascines, is proof against the ball of a wall-piece at
15 yards; at the distance of 200 yards, and even more, it is pierced through by
cannon balls of the smallest calibre.
The penetration of bulls in wool is more than double that in compact earth, even
when the wool is coutuiiied in close, well <|uilted mattresyes pressed between hur-
dles. At 40 yards, a musket ball (round) penetrates m<jre than 40 inches into
Woollen mattresses thus placed together. sf

PENETRATION IN MASONRY. 383
The solid shot broke against the granite, but not against the freestone or brick.
The (/riif-rnl effect is less in brick than in granite.
The shells broke into small fragments against each of the three materials.
The circumstances attending the penetration of the shot and shells corresponded
with those stated below in the experiments at Met/.. The wall used as a target at
Fort Monroe Arsenal was built of dressed stone and of the best bricks, laid in
hydraulic cement j but being an isolated wall (10 feet stiuare of each material, and
5 feet thick, with 3 counterforts), and being battered before the masonry was per-
fect!}' set, the effect of the projectiles in xlKitterinij the masonry around the point
struck was greater than indicated by the experiments referred to.

ORDNANCE MANUAL.
It has been ascertained by experiment that a musket roinul ball h ivinp a velo-
city oC '.\C>2 feet, at the moment of impact, will just pass through a white pine
bnaril I iuch thick: and that, with the same velocity, the ball has sufficient force
to shatter the leg bono of an ox covered with one thickness of stout harness
leather. A musket ball moving with this velocity would, therefore, inflict a wound
which would disable a man or beast; or a spherical-eose shot having this velocity
at the moment of bursting, would be effective against troops in its immediate
vicinity. '
A musket ball with an initial velocity of SS."? feet will pass through one-inch
white pine board at 100 yards : hence a spherical-case shot, moving with that velo-
city at the moment of bursting, would be effective at 100 yards <listaDt from th«
place of bursting. The remaining velocity at 100 yards, as computed, is .'J04 feet.
Effects of Shot on Cttst-Jron.
Shot projected with even a small velocity will break pieces of cast-iron of very
large dimensions. A 2-1-pounder ball fired with a charge of l-12th, anil moving
•with a velocity of 88.3 feet in a second, sj)lit a block of cast-iron 12 inches wide by
40 inches thick, to the depth of 40 inches, in two shots. The fragments of the
block and of the broken shot are jirojected with sufficient velocity to produce the
most destructive effects.
Cast-iron, therefore, is not a proper material for gun-curriugcs, or for revetcmontt
of furtificatious.

requires 1 hour and 15 minutes to heat them to a red heat. After the furnace is
once heated, a 21-pdr. shot is brought to a red heat in 25 minutes; the 32 and 42
require a few minutes longer. Two or three men are required to attend a furnace.
Grates. — In siege batteries, or in other situations where there are no furnaces, a
grntc is used for heating shot. This grate consists of 4 bars, 1.75 inch square, 3
feet long, placed diagonally, 4 inches apart, resting on .3 iron stands with legs 1
foot high.
To unr the t/rntc. — Make an excavation 1 foot deep and width of grate, with no
slope at the sides or in rear, open in front. Place the grate in it, on stones or
bricks, rising about 4.5 inches above the bottom ; make a roof over it with hoops of
flat iron, covered with sods and with 18 inches of earth, leaving in the back part
a chimney 6 inches square. Put the shot on the grate, leaving about one-fourth of
the length free in front; on this pnrt, and under the front of the grate, put the
wood, cut into pieces about 14 inches long and 2 inches or 2.5 inches thick. Make
use of a thick sod, as a register, to regulate the draught of the chimney, so that no
flame shall issue from the front of the furnace. This little furnace, which will con-
tain about fifteen 24-pdr. balls, heats them to a red heat in 1 hour, and will supply
3 guns: it requires the attendance of one man.
Implements. — 2 pokevK, for stirring the fire, made of 3 -inch round iron, •''ij feet
long, the end bent at a right angle; 2 iron forki, for taking out the shot. These
forks are immersed alternatelj' in water to cool them. 1 roup, to rub the scales
from the balls when they have been overheated ; 1 pair to»g/i with circular jaws,
for taking up shot ; 1 iron rake, to remove the cinders, etc., from the ash-pit ; 1
trovgh or tub, 1 hnclcet, 1 barrel ; 1 rammer, with the head covered by a circular
plate of sheet-iron, of rather larger diameter than the ball, to remove the clay
which may stick to the sides of the bore when clay wads are used; 1 ladle (to each
piece) for carrj'ing the balls, formed of an iron ring the interior of which is
bevelled to fit the ball, with 2 arms inserted into wooden handles : for small cali-
bres it is made with 1 handle.
Wads may be made of good clay, free from sand or gravel, moistened just
enough to work well; the wads are cylindrical, 1 calibre long. But it is preferable
to use hay wads that have been steeped in water for 15 minutes and allowed to drip.
Cartrid(je» for hot shot are made of cannon cartridge paper or parchment well
pasted, to prevent the powder from sifting out; they should be carefully examined
before use, to see that there are no holes in them. It is best to use two cartridge-
bags, one within the other.
Manner of loading. — Elevate the muzzle sufliciently to allow the ball to roll in;
ram the cartridge home carefully, and a dry hay wad over it; theu a wet hay or
clay wad : prick and prime; insert the ball, and put a wet hay or clay wad over it;
this second clay wad may be only ^ calibre long. It is a good precaution, also, to
pass a wet sponge into the gun just before putting in the shot. When wet hay
wads arc used, steam is seen to issue from the vent as soon as the ball gets home;
this is the effect of the heat of the ball upon the water contained in the wad ; no
388
ORDNANCE MANUAL.
danger can result from it, as the ball may he allowed to cool in the gun without the
charge taking fire ; but it is better to fire without much delay, as this steam would
injure the powder.
The penetrations of cold and hoi shut into wood are equal under the same cir-
cum8tancc8. A red-hot shot retains sufiBcicnt heat to set fire to wood after having
Htruck the water several times. The fire is communicated more rapidly and cer-
tainly to the wood when the ball does not penetrate more than 10 or 12 inches,
because at a greater depth the communication with the external air is not suffi-
ciently free. It is proper, therefore, to fire with small charges, i to i weight of the
shot, according to the distance, in order that the shot may remain in the wood and
not peni'triitc too deep.

Chapter Fourteenth
MATEEIALS.
TIMBER.
The selection, inspection and seasoning of timber for ordnance purposes require
especial attention. The quality of the wood, and the defects to which it is subject,
depend much on the soil, the exposure, and particularly the climate in which it
grows.
In the United States, the climate of the states in the North and Middle is most
favorable to the growth of the timber used for ordnance purposes.
Kinds of Timber used.
The kinds of wood, and the uses to which they are principally applied in ordnance
construction, are as follows, viz :
White oak (quercns alha). — The bark is a grayish white, the leaf long, narrow
and deeply indented ; the wood is of a straw color, with a reddish tinge, tough and
flexible. It is the principal timber used in the construction of all kinds of artillery

White beech. Red beech {fngus n!/lvestn's, farjits /erntginca) are the most suit-
able for saddle-trees, fuzes and mallets; also for plane stocks and various other
tools.
White ash (fraxinus Ainericaiia) is straight grained, tough and elastic; it ie
used for sponge and rammer staves, shafts for light carriages, and, in case of neces-
sity, for handspikes, tool handles and sabots. There is but little difference in
quality throughout the whole thickness; the outside is rather tougher. It lasts &
long time when protected, but rots quickly when exposed to the weather.
Elm {itlmus Americana) is well suited for fellies and for small naves.
UiCKORY [jaglans tomentona) is very tough and flexible ; the most suitable wood
for handspikes and tool handles, and for wooden axle-trees.
Black walnut {juglans nigra) is hard and fine grained; it is used for ammuni-

Doo WOOD (ciirnv jloridn) is hard and fine grained, suitable for mullets, drifts, etc.
Selection of Standing Trees.
Wood grown in a m^ist soil is less firm and decays sooner than that grown in a
dry, sandy soil, but the trees are generally larger.
The best limber is generally found on a dark soil mixed with stones and grarel.
Poplar, cypress, willow, and some others which grow best in a wet soil, are excep-
tions to this rule.
The hardest and most dense woods, and those least subject to decay, grow at the
South : but they are more liable to split and warp in seasoning.
Trees grown on jilaius, or in the centre of forests are less dense than those from
the edge of the forest, from the sides of hills, or from open ground ; but they are
generally more free from limbs and of finer growth. The aspect most favorable to
the production of sound, straight timber, free from defects, is that which is shel-
tered from the prevalent winds. The vicinity of salt water is favorable to the
strength and hardness of white oak.
Trees should be selected in the latter part of July or first part of August: for at
this season the leaves of the sound, healthy tree are fresh and green, while those of
the unsound are beginning to turn yellow. A sound, healthy tree will be known by
its top branches being vigorous and well covered with leaves, the bark even and of
uniform color., A rounded top, a sparse covering of leaves, some of the leaves
turning yellow before the rest, a rougher bark than common, covered with parasitic
plants, streaks or spots, indicate a tree on the decline. The decay of branches at
the top, of large branches, and the separation of the bark from the wood, arc infal-
lible signs that the wood is impaired.
Felling Timber.
The most suitable season for felling timber is that in which vegetation is at
rest — which is the case in midwinter and in midsummer. Recent experiments indi-
INSPECTION OF TIMBER. 391
cate the latter scascn, say the month of July, as the proper season : but the usual
jiractice has been to fell trees for timber between the first of December and the
middle of March.
The tree should be allowed to attain its full maturity before being felled. Oak
matures at seventy-five to one hundred years and upward, according to circum-
jitances. The ago and rate of growth of a tree are indicated by the number aud
size of the rings of annual increase in a cross-section.
The tree should be cut as near the ground as possible, the lower part being the best
timber. Leaning trees should always be cut so as to fall at right angles to the
direction of greatest inclination : and all trees, especially oak, shouM be cut entirely
through the heart while standing, and the woodman should allow sufficient kerf to
enable him to cut the tree completely off, by rapid strokes of the axe, after the troo
lias started to fall. These precautions will jirevctit splintering at the biitt.
Getting out Timber.
As soon as the tree is felled, it should be immediately stripped of its bark and
raised from the ground. A short time only should elapse before the sap-wood is taken
off and the timber reduced nearly to the dimensions required for use. This is done,
generally, by the saw : but those pieces requiring great strength and toughness, such
as spokes, poles, handspikes, and splinter-bars, should be split. These pieces should
always be taken from the butt cut of young, straight grained trees of such size as to
furnish but one piece between the sap and centre heart, the width in the direction of
the radius.
Naves should be taken from the butts of trees of suitable size to leave them, after
the removal of the sap-wood, IJ inch greater in diameter than the finished size.
They should be cut off S((uarc about two inches longer than the finished length, and
bored through their axes with an auger h inch less than the small end of the nave-
1)0X which they are to receive. This facilitates their seasoning and diminishes
cracking.
Pieces for fellies should always be got out so that the planes of their broad faces
shall run nearly toward the centre of the tree. Slab piecei are not fit for this purpose.
Inspection of Timber.
Examine the timber all over carefully, whenever it can be done, aifter several days
of fine weather, in order to see better certain defects which moisture renders less
:il)pareiit.
The quality of the wood is in some degree indicated by the color, which should be
nearly uniform in the heart-wood, a little deeper toward the centre, aud free from
sudden transitions. White spots here and there indicate decay, and should cause the
rejection of the piece. All pieces containing sap-wood should be rejected, except
hickory and ash ; in this kind of wood the sap-wood is generally the toughest and
best. The sap-wood is known by its white color; it is next to the bark, aud very

wood found (iurroun<lcd by Rood, hard wood ; tbiR may be called the second siip, and
should cniise the rejection of the piece in which it occurs.
Ri'jcct jiicces containing the centre heart, except in timber which, from its size,
cannot be procured free from it. Even in these it is better to use biiill hrntnn of
smaller jiicces free frnm centre heart, on account of the great difficulty in seasoning
such large pieces, and ihcir exlreme liability to being attacked by ilry rot during the
process.
In pieces which have been got out by s)ilitting, the oeeurrencc of nhort bends
indicates that they have been taken from the u|)|)er part of the tree; and the nintiintf-
onl of tiio grain, so as to show the ends of the fibres along the side of the ^tiek, is an
unfailing indication of brashncss. Reject the i)ieec in which cither occurs.
Pieces for handspikes should be free from knots near the fulcrum end. After
inspection, each slick is marked on each end, with while lead, with the initials of the
contractor, the year when received — a letter designating the purpose for whicli the
timber is intended, and the number of pieces contained in each stick. On small
Slicks, as spokes, it is sufficient to mark the uootractor's name and data on uno end,
the fihiipu of the piece showing for what it is inltiodcd.
Defects of Timber — esperiolly of Oak.
WiinJ-flinL-rt are cracks separating the cuucentrio layers of wood from each othor:
a circular crack : it is a serious defect.
»S)»/('M, cheat*, and erack*, extending toward the centre, if deep and strongly
marked, render the timber unfit for use, uuless the purixise fur which it is inlvnded
will admit of its being split through them.
These defects are found iu young trees as well as old, and arc no signs of the
aiteraliou of the quality of the timber. They always increase in extent in seasoning.
Jirnsh-iroud is generally con8ei|ueut on the decline of the tree from age. The wood
is porous, of a reddish color, and breaks short, without splinters, and, in marked
oases, the chips crumble to pieces. This wood is entirely unfit for artillery carriages.
Delud timber (that which has been killed before being felled, or which has died
from other causes) should be rejected.
Kiuitiy timber: that containing a great many knots, though sound, usually of
stunted growth. It is difficult to work, and weak when cross-strained ; reject.
Ttrisud tcoodf the grain of which winds spirally, is unfit for long pieces; it may
be used in short ones, as naves or short transoms, etc.
Dry-riit. — This is indicated by yellow stains. Elm and beech are soon affected,
if left with the bark on.
Large or decayed knots should cause the piece to be rejected.
Seasoning and Preserving Timber.
Timber fresl^y cut contains about 37 to 48 per cent, of liquids. By exposure to
the air in seaWBing one year, it loses from 17 to 2.') per cent., and seasoned wood
still retains from 10 to 15 per cent.
SEASONING AND TRESERV^ING XniBER. 393
Timber of large dimensions is improved and rendered less liable to warp and
crack in seasoning by immersion in water for some weeks, according to the si/.e.
For the purpose of seasoning, timber sbonld bo piled under shelter and be kept
dry; it should have a free cirfulation of air about it, without Iteing exposed to
strong currents. Place the Ijottom pieces on skids, which should be sound, raised
not less than 2 feet from the ground ; leave a space of an inch between the pieces of
the same horizontal layers: place slats or piling-strips between different layers, one
near each end of the jiile. and c)thcrs at short distances to keep the timber straight.
These strips should be one over the other, and in large piles should not be less than
1 inch thick. Spokes arc piled in square piles, the length of one piece, omitting
the slats. Light timber may be piled in attics, heavy timber on the ground floor.
Each pile should contain but one kind of timber, and be marked with the date of
inspection and the number and kind of pieces it contains. Pieces of the same kind
and of different dates of ret'cipt, if piled one on the other, should have that which
was received first piled on top. The piles should be at least 2i feet apart: this
secures free access at all times to the different kinds of pieces in store.
Timber should be replied at intervals varying with the time it has been in store,
and all pieces showing evidences of decay should be thrown out, to prevent their
affecting those which are still sound.
Timber storehouses are best provided with ))liuds. which keep out the rain and
snow, but which can be turned to admit the air freely in fine weather. They should
bo kept entirely free from pieces of decayed wood.
This gradual mode of seasoning is considered the most favorable to the strength
and durability of timber, but various methods have been proposed for hastening
the process. For this purpose, Httnuiiiuj timber has becu applied with success; and
the results of experiments with Mr. Kyan's process of saturating timber with a
solution of corrosive sublimate have been highly sntisfactory ; this is said to harden
and season the wood, at the same time that it secures it from the dry-rot and from
the attacks of worms. The process of Mr. Earle, which consists in saturating the
wood with a hot solution of the sulphates of copper and iron, mixed together, has
been tried by the Ordnance Department, and found to impair the strength without
increasiug the durability of the limber. Kiln dryinij i^ serviceable only for boards
and pieces of small dimensions, and is apt to cause cracks and to impair the
strength of wood, unless performed very slowly. Charring or jynintinrj is highly
injurious to any but seasoned timber, as it effectually prevents the drying of the
inner part of the wood, in which, consequently, fermentation and decay soon take
place.
Timber piled in badly ventilated sheds is apt to be attacked with dry-rot. The
first outward indications are yellow spots on the ends of the pieces and a yellowish
dust in the checks and cr.acks, parficularl}' where the pieces rest on the piling-
strips; when cut, the timber is of a dull, reddish brown color, dotted over with small
white specks, and it is brittle and very weak.
Timber requires from 2 to 8 years to season thoroughly, according to its size. It

IRON. 395
IRON.
Iron is obtained from its ore."*, in which it generally exists in tbe .«tate of an
oxide, combined with earthy or stony matters, and frequently with carboti, sulphur,
artenic, mngncsia, manganese, etc. Iron ores are classed and named according to
their different combinations, as magnetic, specular, micaceous, clay iron-stone, red
hematite, brnun hematite: tbe last named is the ore from which tbe Salisl)ury and
the Juniata irons are extracted; the first, that from which tbe Swedish iron is
obtained ; and the clay iron-stone that from which the iron of England is made.
The foreign substances which iron is found to contain modify in a marked man
ncr its essential properties. Carbon adds to its hardness, but destroys some of its
characteristic qualities, and produces ca.st-iron or steel according to tbe proportion
of carbon it contains. Sulphur renders it fusible, difficult to weld, and brittle
when heated, hot short. Phosphorus renders it cold short, but may be present in the
proportion of 2-lOOOths to 3-lOOOths without affecting injuriously its tenacity.
Aiitimoni/, arsenic and copper have the same effect as sulphur — tbe last in a greater
degree.
Cast-iron.
The process of making cast-iron depends much on the kind of fuel used: char-
coal, coke, bituminous and anthracite coals, are all used. 'When anthracite coal is
employed, the ore is placed at once in the blust-furnacc: when charcoal is used, the
ore is first roasted, by distributing it in alternate layers with waste coal, wood or,
sometimes, with charcoal, .and the pile thus formed is ignited and burned in tbe
open air. For the more refractory ores a kiln similar to that used for burning lime
is required. The ore is rendered, by this operation, more porous and easily broken
into small pieces, by which it is more readily acted upon in the smelting furnace.
The small pieces would be disadvantageous in an anthracite furnace.
Smelting is the process by which the iron is separated from the refractory sub-
stances with which it is combined in the ore. It consists in raising the ore to a
high heat in contact with carbon and a suitable flux in the blast or smelting fur-
nace. The flux unites with the earthy matter of the ore, forming a glassy sub-
stance called slag or cinder, and the carbon unites with the oxygen of the ore,
setting the iron free, which in turn unites with a portion of the carbon and forms a
fusible compound, carburet of iron, or cast-iron.
Tbe melted iron and slag descend to tbe bottom of the furnace, the slag forming
a covering to the pool of iron and protecting it from the action of the blast. As
the_v accumulate, tbe slag runs off over the dam, and is a good indication, to an
experienced eye, of the quality of metal tbe furnace is making.
The furnace is generally tapped once every twelve hours, and the metal is run out
intoxhaunels formed in the sand, and is known as j)igs.
Limestone is the flux used for most ores : clay is sometimes required to mix with
ores containing much limestone.
A larger yield from the same furnace, and a great economy in fuel, are cffeotcd

by the use of a hut hlati. The greater heat thue produced cauvos the iron to com-

Cant-iron for cannon and for all purposesi rci|uiring great Htrcngth should be

f'i;i iron, according to the proportion of carbon which it contain«, ix divided into
fuiiuili-)/ iriin and /<>rfje iron, the latter being adaptecl only to conversion into mal-
leable iron ; while the former, containing the largest proportion of carbon, can be
used cither for casting or for making bar-iron.
There are many varieties of cacf-iron, differing from each other by almost inMn-
sible ^hadps ; the two principal divisions are t/rui/ and irhilr, so called from the color
of the fracture when recent Their properties are very different.
firny iron is softer and less brittle than white iron: it is in a slight degree mal-
leable and flexible, and is nut sonorous: it can be easily drilled and turned in (be
lathe, and dovf not resist the file. It has a brilliant fracture, of a gray, or, some-
times, a bluii'h gray color: the color is lighter as the grain becomes closer, and its
hardness increases at the same time.
It melts at a lower heat than white iron, becomes more fluid, and prc«ervci its
fluidity longer; it runs smoothly; the color of the fluid metal is red, and deeper in
proportion as the beat is lower: it does not stick to the ladle: it fills the moulds well,
contracts less and contains fewer cavities than white iron: the edges of a easting are
sharp, and the surface smooth, convex, and i overed with carburet of iron. A me<lium
■iied grain, bright gmy color, lively aspect, fracture sharp U^ the touch, and a close
eompaei texture, indicate a good quality of iron. A grain cither very large or very
small, a dull, earthy a-pvct, loose texture, dissimilar crystals mixed together, indi-
cate au inferior i|uali(y.
Orav iron is uj'ed for ordnance jiuriKtses where the pieces are to be bored or fitted.
ItB tonacity and specific gravity are diminiihui by annealing, lu mean specific
gravity is l.MH).
H'Aife iron is very brittle and sonorous: it resists the file and the chisel, and ia
bUtceptible of high polish ; the surface of a casting ia concave; the fracture prc««nt«
a silvery appearance. jeneraJly fine grained and compact, somctimM radiui.ug, or
lamellar.
When melted it is white, and throws off a great number of sparks, and it« t|UaUliM
arc the reverse of those of gray iron ; it is, therefore, unsuitable for ordnance pur-
poses. Its tenacity is iiirreattJ and its specific gravity diminisktd by annealing. It«
mean specific gravity is ".-'iUO.
Motiltd iron is a mixture of white and gray ; it has a spotted appearance ; it Sows
well and with few sparks: the casting has a plane surface, with edges slightly
rounded. It is suitable for making shot and shells.
A fine mottled iron is the only kind suitable for making castings which require
great strength, such as cannon. The kind of mottle will depend uach on the sit*
•f the casting.
MALLEABLE IRON. 397
Besides these general divisions, the manufacturers distinguish more particularly
the different varieties of pig metal by numbers, according to their relative hardness.
No. 1 is the softest iron, possessing in the highest degree the qualities described
as belonging to gray iron : it has not much strength, but on account of its fluidity
when melted and of its mixing advantageously with old or scrap iron, and with the
harder kinds of cast-iron, it is of great use to the founder, and commands the highest
price.
No. 2 is harder, closer grained, and stronger than No. 1 ; it has a gray color and
considerable lustre. It is the kind of iron most suitable, in general, for making shot
and shells.
No. 3 is still harder than No. 2. Its color is gray, but inclining to white; it has
considerable strength, but it is principally used by the founder for mixing with other
kinds of iron.
No. 4 is brujht iron ; No. •>, mottled ; No. G, white — which is unfit for general use
by itself.
The qualities of these various kinds of iron seem to depend on the proportion of
carbon, and on the state in which it is found in the metal. In the darker kinds of
iron, where the proportion is sometimes 7 per cent, of carbon, it exists partly in the
state of graphite or plumbago, which makes the iron soft. In white iron, the carbon
is thoroughly combined with the metal, as in steel.
Cast-iron frequently retains a portion of foreign ingredients from the ore, such as
earths, or oxides of other metals, and sometimes sulphur and phosphorus, which are
all injurious to its quality. Sulphur hardens tlic iron, and, unless in a very small
proportion, destroys its tenacity.
These foreign substances, and also a portion of the carbon, are separated by melt-
ing the iron in contact with air, and soft iron is thus rendered harder and stronger.
The effect of remelting varies with the nature of the iron and the kind of ore from
which it has been extracted; that from the hard ores, such as the magnetic oxides,
undergoes less alteration than that from the hematites; the latter being sometimes
changed from No. 1 to rohite bj' a single remelting in the air furnace.
The color and texture of cast-iron depend greatly on the size of the casting and
the rapidity of cooling; a small casting, which cools quickly, is almost always
white, ivnd the surface of large castings partakes more of the qualities of white metal
than the interior.
All cast-iron expands forcibly at the moment of becoming solid, and again con-
tracts in cooling; gray iron, as before remarked, expands more and coutract.s less
than other iron.
The contraction is about 1 -100th for grey and strongly mottled iron, so that the
dimensions of a pattern for casting should be about 1-lOOth larger than the size re-
quired for the casting.
Malleable Iron.
Malleable iron is made from the pig, in the bloomcry fire or in the puddli»g fur-
nace— generally in the latter.

The operation of puddling is a most important one, as tho quality of the iron
depends so much upon the skill with which it is conducted.
The metal is first melted, and the puddler then begins to stir it, exposing each
portion in turn to tho action of the flume, and continues this as long as ho is able
tu work iU When it has lost its fluidity, ho forms it into puddlers' balls, weighing

object is to press out as perfectly as possible the liquid cinder which the ball still
contains: it also forms the ball into shape for the puddle-rolls. A heavy ham-
mer, weighing from 6 to 7 tons, effects this object most thoroughly, but not so
cheaply as the squeezer. The ball receives from 15 to 20 blows of the hamra'^r,
being tiirued from time to time us required: it is now called a bfoam, and is ready
to bo rolled or hummerud. Or the ball is pai^sed once through the squcexer, and is

Piling. — To prepare rough bars for this operation, they are cut, cither hot or
eold, by means of a strong pair of tkears, into such lengths as are best adapted to
tho site of the finished bar required; the sheared bars are piled, one over the other,
to the number of from two to six or more pieces, according to the size required —
when the pile is ready for balling.
Balling. — This operation is performed in the balling furnace, which is similar to
the puildling furnace, except that its bottom or hearth is made up, from time
to time, with sand ; it is used to give a welding heat to the piles to prepare them
for rolling.
KiMsuiNG-BOLLS. — The balU are passed successivel}- between the rollers of
various forms and sires according to the shape of the finished bar required.
The bars are straightened on a cast-iron bed, with heavy wooden beetles,-
The quality of the iron depends on the kind of pig used, the skill of the puddlcr,
and the absence of deleterious substances in the furnace.
MALLEABLE IRON. 899
The strongest cast-irons do not produce the strongest malleahle iron.
For many purposes, such as sheets for tinning, best boiler-plate, and bars for
con%-erting into steel, charcoal iron is used exclusively; and, generally, this kind of
iron is to be relied upon for strength and toughness with greater confidence than
any other — though iron of superior quality is made from pigs made with other fuel
and with the hot blast; iron for gun barrels has been lately made from anthracite

Iron is improved in quality by judicious working, reheating it, and hammering
or rolling: other things being equal, that is the best ir*)n that has been wrought
the most.
Piles are sometimes made of good iron on top and bottom and poorer iron in the
middle : this is easily detected in the fracture. Reject it, where strength and
toughness are required.
Bak-irox. — The iron used in ordnance constructions is generally furnished in
bars of difi'ercnt sizes, or in shapcg. It should be of the best qualit}* of iron, highly
refined.
The quality of iron is generally judged of by its (/rain as shown in a fresh frac-
ture.
The samjile shouM be 1 inch square, or, if a flat bar, i inch thick. Cut a notch
on one side with a cold-chisel, and bend the bar down over the edge of an anvil, or
give it a heavy blow, when lying flat on the ground, with a sledge-hammer; if the
fracture exhibit long, silky fibres, of a leaden graj' color, cohering together and
twisting or pulling apart before breaking, it denotes a. tough, soft iron, which is
easy to work and hard to break, suitable for sheet-iron, wire, etc., but it may weld
badly. A medium, even grain, mixed with fibres as above, but without bright
specks or dark spots, is also a favorable iudicalion. In general, a short, blackish
fibre indicates iron badly refined and mixed with carbon, plumbago, or oxide; if
worked very hot, it may be improved, but there will be a reat waste, A very Jiue,
close grain denotes a hard, steely iron, which is apt to be colJ-vliuri, hard to work
with the hammer or file. A coame grain, with a brilliant, crystallyzed fracture, or
yellow or brown spots, denotes a brittle iron, inclined to be cold-nhurt, but work-
ing easily when heated, and making a good weld. But this test is not always sulE-
cient, as the same iron will present dificrent appearances acc(>rding to the manner
in which it has been forged and the degree of heat to which it has been subjected.
Numerous ci-acks on the edges of the bar generally indicate a liut-xliort iron, which
crjicks or breaks when punched or worked at a red heat, and will not weld; it is
strong when cold, and may be useful in that state, but, if worked, care should be
taken not to subject it to strains at a red heat. Bliiitcrs, jhurn, and cinder-hnhs are
caused by imperfect welding at too low a heat, or by the iron nut being properly
worked, and do not always indicate an inferior quality.
The surest test of the quality of iron is to submit it to the followinL? proofs :
Test when cold. — Bend the iron, if in small bars, several times biu:k and forth in
diflFercut direction.", at sharp angles, with heavy blows of a bannucr, and twist it in
400 ORDNANCR MANUAL.
ft vice. Large pieces are reduced in size at one end, and submitted to the same
tests. Round bars have a screw-thruad cut on them, and arc then hcnt according
to the use for which they are intended. Pieces which are to have holes in tbcm
are tested by punching holes in them cold.
Tent frilir» hot. — Draw out the iron, bend and twist it; split it, and turn back the
two parts, to sec if the split extends up; punch a long hole in the direction of tb«
fibre, and unollior at right angles to it; punch holes of different forms— some near
the edge; weld the iron to iron and to steel ; make chains from small rods ; obacrre
if cracks or flaws weld easily: finally, forge some of the most diflicult pieces for
which the iron is intended.
NOTR iiM FORGING. — Oood iron is often injured by being unskilfully worked.
Care hhould be taken that the iron while heating is not exposed to the air, which
would assist in forming scales of oxide on its surface : it is to prevent this that tho
workman from lime to lime throws sand or clay on his iron to protect it. When
iron i" at a white beat, immediate contact with coal tends to carbonize it and make
it »ttrly. Iron heated for any purpose, and especially for welding, fhould be heated
as rapitlly as possible, in order to expose it the least possible time to tlie action of
the air anil coal; for this purpose, the strongest fuel, with an abuiidiint, steady
blast, is necessary. Defects in iron caused by unskilful working may be remedied
in part: if, for example, iron has been Imrutd, give it a smart heat, protected aa
much as )>ossible from the air; if the iron has been injured by cold-hitmmering, %
moderate aiiiieMliiig heat will restore it; if the iron has become hard an <1 steel j,
give it one or more smart heats, to extract the carbon.
Inspection of Iron for Garrison and Sea-coast Carriages.
The chrck-plntei should be made of iron of good quality, uniform in thicknesf, a
plane surface, and cut near to the required size. Verify the size by a wooden frame
made of the required shupe, and the thickness by an iron gauge. Try the quality
of tho iron by punching holes near the edge at the place for the trunnion-holes.
The railn should be straight on the top, bottom and edge of the flange; try ihem
by laying a straight-edge on them. The web should be a plane surface, without
corrugaliou.s — at right angles to the fiaugcs, which should be smooth and free from
breaks or cracks.
Examine that the welds are all good, that there arc no scams, and that the
iron has not been burned. Verify the cross-section of the rail by a profile cut
from sheet-iron or mahogany; measure the length with a rod of the correct
length.
See that the trough-beams and angle-iron are straight, and their edges sonnd^
without cracks. Verify their length.
Examine the bar-iron by the tests given above for bar-iron, and where the pieces
are cut to lengths, verify them.
Weigh several pieces of each kind of the exact length, sufficient to get a fuir mean
weight, from which the weight of the whole can be calculated.
STEEL. 401
Puddled Steel.
U, in the opriition of puddling, the process be slopped at a particular time
determined by indications given by the metal to an experienced eye, an iron is
obtained of greater hardness and strength than ordinary iron, to which the name of
scmi-stecl, or puddled steel, has been applied. The principal difficulty in its manu-
facture is that of obtaining uniformity in the product, homogeneity and solidity
throughout the entire mass. It is much improved by reheating and hammering
under a heavy hammer.
A tenacity of 118,000 lbs. to the square inch has been obtained from semi-steel
made in this country in this way. Field pieces have been made of this material,
and it is believed that it will answer well for this purpose.
Steel.
Steel is a compound of iron and carbon, in which the proportion of the latter is
from 5 to 1 per cent., and even less, in some kinds. Steel may be distinguished from
iron by its fine grain; its susceptibility of hardening by immersing it, when hot, in.
cold water; and with certainty by the action of diluted nitric acid, which leaves a
black spot on steel, and on iron a spot which is lighter colored in proportion as the
iron contains less carbon.
There are many varieties of steel, the principal of which are—
Natural xteel, which is obtained by reducing the rich and pure kinds of iron ore
with charcoal, and refining the cast-iron, so as to deprive it of a sufficient portion
of carbon to bring it to a malleable state. It is made principally in Germany, and
is used for making files and other tools.
The India steel, called wootz, is said to be a natural steel, containing a small
portion of other metals.
Blhtered steel, or steel of cementation, is prepared bv the direct combination of
iron and carbon. For this purpose, the iron in bars is put in layers alternating
with powdered charcoal, in a close furnace, and exposed for 1 or 8 days to a heat of
about 70° Wedgewood. and then suffered to cool for as many days more. The bars
on being taken out are covered with blisters, have acquired a brittle quality, and
exhibit in the fracture a uniform crystalline appearance. The degree of carboni-
zation IS varied according to the purposes for which the steel is intended, and the
best qualities of iron (Russian and Swedish) are used for the finest kinds of steel.
Tilted steel is made from blistered steel moderately heated and subjected to the
action of a tilt-hammer, by which means its tenacity and density are increased and.
it is thus adapted to use.
Shear steel is made from blistered or natural steel refined by piling thin bars into
fagots, which are brought to a welding heat in a revcrbcratory furnace, and ham-
mered or rolled again into bars ; this operation is repeated several times to produce
the finest kinds of shear steel, which are distinguishad by the names of half shear,

tingle thenr nilil dnuhle ihenr, or pteel of 1 mark, of 2 mnrku, of r! innrkt, etc.,
according to the Dumber of times it has been piled.
Caul-Heel is made by bre.nkinjf blistered steel into small pieces and melting; it in
close crucibles, from which it is poured into iron moulds : the ingot is then reduced
to a bar by hammering or rolling, as described under the bead of malleable iron,
these operations being performed with great care. Cast-stccl is the finest kind of
steel and best adapted for most purposes: it is known by a very fine, even and
close grain, and a silvery, homogeneous fracture ; it is very brittle, and acquires
extreme hardness, but is diffioult to weld without the use of a flux. The other kinds
of steel have a similar appearance to cast-stuul, but the grain is coarser and less
homiigeneous ; they are sort<'r and less brittle, and weld more readily. A fibrous
or lumcllar appearance in the fracture indicates an imperfect steel. A material of
great toughness and elasticity, as well as hanlnesi', i.s made by forging together
steel and iron, forming the celebnited (lnma»k- gitrl. which is used for sword blades,
springs, etc.: the dninasked appearance is proilufcd by the action of a diluted
acid, which gives a black tint to the steel parts, whilst the iron remains white.
Various j'nney ulerlit, or alloy.s of steel with tilrer, jilntinum, rhnriium and nlumin-
iiini have Iteen niaile with a view to imitating the Damascus steel, w<>ot7., etc.. and
improving the fabrication of some of the finer kimls of surgical and other instru-
ments.
PRorr.nTiKS or stkkl. — The best steel possesses the following characteristic! :
heated to redness and plunged into cold water, it bicnmcs hard enough to scratch
glass and to resist the best files; the hardness is uniform throughout the piece:
after being tempered it is not easily broken ; it welds readily : it doe« not crack or
split ; it bears a very high heat, and preserves the capability of hardening after
repeated working ; the grain is fine, even and homogeneous, and it receives a bril-
liant polish. Its specific gravity is 7.816, being greater than that of iron.
Test. — Break a few bars, taken at random : make tools of them and try them in
the severest manner.
Hardening and TKMrERiSG stkel. — On these operations the quality of manufac-
tured steel in a great measure depends.
Hardening is effected by heating the steel to a cherry red, or nntil the scales of
oxide are loosened on the surface, and plunging it into a liquid, or placing it in
contact with some cooling substance : the degree of hardness depends on the heat
atd the rapidity of cooling. Steel is thus rendered so hard as to resist the hardest
files, and it becomes at the same time extremely brittle. The degree of heat and
the temperature and nature of the cooling medium must be chosen with reference
to the quality of the steel and the purpose for which it is intended. Cold water
gives a greater hardness than oils or other fatty substances, sand, wet iron scales or
cinders, but an inferior degree of hardness to that given by acids. Oil, tallow, etc.,
prevent the cracks which are caused by too rapid cooling. The lower the heat at
which the steel becomes hard, the better.
Tempering- — Steel in its hardest state being too brittle for most purposes, the
WELDING COMPOSITION. 403
requisite strength and elasticity arc obtaincil l>.v tempering — or letting dou-n the tem-
per, as the workmen term it^ — which is perfuruied by heating the hardened steel to a
certain degree and cooling it quickly. The requisite heat is usually ascertained by
the color which the surface of the steel assumes from the film of oxide thus formed.
The degrees of heat to which these several colors correspond are as follows :

If the steel be heated higher than this, the effect of the hardening process is
destroyed.
Case-hardening. — This operation consists in converting the surface of wrought
iron into steel, by cementation, for the purpose of adapting it to receive a polish or
to bear friction, etc. ; this is effected by heating the iron to a cherry red, in a close
vessel, in contact with carbonaceous materials, and then plunging it into cold
water. Bones, leather, hoofs and horns of animals are generally used for this pur-
pose, after having been burnt or roasted so that they can be pulverized. Soot is
also frequently used.

Sheet-Iron.
Slirrt-irnn is made by rolling. It should be soft nn<l tiiu^h. its siirfiiee very
smooth, withfiut holes or thick scales; it is generally of a blui.-h color, simictimes
clouded: the sheet should be of regular thickness, clastic, and crackling when
bent in the hamls. When bent at a right angle, there should be no iipjicnrancc of
fracture on the exterior.
Iliimin uhtii-iron has a planished, glossy, and smooth surface of gray oxide of
iron; it should be free from rust or flaws, and be very soft and tough. Punch
holes in it near the edge, and see that there arc no flaws or cracks after this opera-
lion.
The severest test of sheet-iron consists in hammering a juirt of the sheet into a
concave form.

Sheet-Tin.
Sheet-tin is made by coating sheet-iron with tin. The iron is first leoured, or
thoroughly cleaned, by means of an acid, and then immersed in melt«d tin. There
are two kinds — called oingh tin and double tin, differing in thickness and in the
quantity of tin with which the iron is coated. The surface of the sheets should be
bright and smooth, free from specks, beads and blisters.

English files are generally used at the arsenals and armories.
Files should be made of the best cast-steel. The teeth are generally cut at an
iinjjie of 60° with the centre line ; at a smaller angle the teeth are apt to choke,
and at a greater angle they do not cut.
In choosing files, they should be examined to see that they are straight, that
they ure free from cracks and flaws, and that they are cut regularly. The teeth
should not be turned or broken by filing on iron or tempered steel. One out of
each dozen may be tried on a piece of t«mpered steel, such as the tang of a file
screwed in a Ticc ; the file should "take" in its whole length, both on the flat
and edge, and should not cut in drawing back ; it should not make furrows, or
show a tendency to deviate from the direction given to it by the hand. The quality
of the steel may be determined by breaking some of the files and working the steel
in the forge.

Liquor for tinnm.vg or solderivg. — Dissolve 3 ounces of zinc in a pint of muriatic
acid, letting it stand in a warm place about 8 hours; strain the solution through a
cotton or linen cloth ; add a teaspoonful of pulverized sal-ammoniac to a pint of the
solution, and let it boil for ten minutes; when cool it is fit fur use.
To TIN IRON. — Immerse the iron in the cleaning pickle; if the surface be rough,
let it remain in the pickle about 4 hours, or until all the scales can be rubbed ofi°.
Then dip the iron into the solution of zinc, and immediately afterward into the
'melted tin, which must be kept a little above the melting point. Let it remain in
the melted tin until the latter has ceased to be agitated, when the iron will have
become warm enough for the tin to adhere; on taking it out, wipe or shake off the
surplus tin.
To TIN COPPER. — It is only necessary to dip the copper into the solution of zinc
and then into the bath of tin ; or to clean the copper with diluted sulphuric acid
before immersing it in the tin.

ROPES.
The size of a rope is designated by the circumference or girth measured with ».
thread : thus, a 3-inch rope measures 3 inches round. The length is usually expressed
in fathoms.
Stukngtii. — The utmost strength of good hemp rope is G,400 lbs. to the square
inch; the weight which it will bear before breaking is expressed in tons by one-ji/th
of the square of the girth in inches; in practice, a rope should not be subjected to
more than half this strain. It stretches from l-7th to l-5th, and its diameter is
diminished from l-7th to l-4th, before breaking. A difference in the quality of the
liemp may produce a difference of l-4th in the strength of ropes of the same size.
AVhite rope is stronger than tarred rope, and the difi"erenee is increased by age and
service: therefore, such ropes only as are to be immersed in water should be tarred.
Oil or gre.ase diminishes the strength of rope without adding to its durability.
The strength of manilla rope is less than that of hemp rope.
Quality. — The quality of hemp is in some measure indicated by its color: the
the best is of a pearl gray ; the next, greenish ; then, the yellow ; a brown color indi-
cates that it has been rotted too long and has begun to decay. Brown spots show
that it has moulded and the spots are decayed. The odor should be strong, but free
from a musty, tainted smell. It should be well combed, pliant, and free from stalks.
The yarns should be fine spun and slightly twisted : they are from i to i of an inch

in girlli. A rope is defeotivc when the yania arc of unequal sizes or uncijuotly
twixtcd ; when it is fuxzy before being used; and when it cuntains pieces of stalk,
indicatinf^ that the hemp was nut well combed.
TwiKTrNO OR i.AYiNM. — Tho Dumbcr of yarn* in a *frniK/ of cordage rarioa from Itt
to 2!), and sovcral strands are combined, or laid, to form a large rope. A rope is
■aid to be twisted i or ^ when it is J or i shorter than the strand. For artillery
service ropes should lie twinted J.
The degree of twisting may be determined by constructing a right-angled triangle,
tho base of which is the circumference of the rope, and the height the length of one
revolutioif (if the strand, nicaKured parallel to the axis; the difference between thix
height and the hypothcnuse is the <|uantity by which the rope is twinted.
PiiKSEKVATiuN IN SToRK. — Ropcs should be jilaccd in the upper stories of a build-
ing, coiled up and labelled: large rojies on skids, so as to allow the circulation of
air: small ropes hung up to the joists, on pins or hooks. Ropes should not be coiled
until they are perfectly dry : they should be uncoiled every year, and stretched out
for several days at the beginning of the dry season.
Uo]>es which have been too long in Ktore lose their strength.
COAL.
Charcoal.
Charcoal is made from either hard or soft wood; that from the firmer, such as
oak, rou}ilc, boech, chestnut, is the most serviceable, giving the greatest quantity of
heat for un equal weight of coal.
For ordinary purposes it is burned in heaps or stacks. Wood from 18 to 20 years
old is to bo preferred. It may be charred immediately after being felled ; if left for
a year exposed to the weather before being burned, it produces an inferior coal.
Select siiuuil woud; cut it into pieces from 4 to Ti feet lung, and split those which
lire more than 4 inches in diameter.
It is well to make stacks, as far as practicable, of wood of the same kind, or of
such as differ from each other but little in their general nature. If it be necessary
to use soft and hard woods in the same stack, place the former on the outside.
Making cHAncoAi.. — Choose a dry spot on which to place the stack, sheltered
from the wind: level the ground. Plant a stake iu the middle of the space, and
cover the bottom of the pile with wood placed in a direction converging toward the
centre, the intervals being filled up with small ^Micks; place the rest of the wood
around the stake, the pieces nearly upright and close together, in several tiers, cover-
ing the whole with a layer of wood placed as close together as possible; leave one or
more horizontal openings near the ground, from the exterior to the centre. CoTet
the stack, commencing at the top, with leaves and a coat of wet sod alx>ut 4 inches
thick, leaving open a space 6 inches high, all round the bottom, for the escape of the
air and steam.
Draw out the stake, and set fire to the pile, either by means of the bole left by the
PIT COAL. 411
stake, or through the horizontal gallery, which may have been previously filled with
combustible materials. Push the fire actively until the flame comes out at the top of
the stack, in order to ignite the whole of the bottom part, and to expel the steam,
which would otherwise occasion explosions. Then close the hole at the top, and
cover the lower part of the pile, leaving small openings at intervals: the smoke
should now escape equally from all parts of the stack, except toward the top, which
is kept closed in order to prevent a draught. When the stack has mrcatcd sufficiently,
increase the thickness of the coating of earth ; moderate the fire, and direct it, by
means of openings on the sides, in such a manner that the combustion may be equal
in every part and that the fire may be always drawn toward the bottom. Leave the
holes open as long as the smoke is black and thick, and close them when it become^
light and of a bluish color. The charring is completed when the flame escapes
through the openings at the bottom; then stop the holes and cover the pile well with
earth, which should be renewe<l after 24 hours; extinguish the fire entirely, and let
the pile stand 12 or 24 hours more. Open it on one side only; select the coal, and
separate what is imperfectly burnt. Wood furnishes in this way, on an average,
about 16 or 17 per cent, of charcoal.
Large stacks are the most advantageous : as much as 50 or 60 cords of wood may
be put into one.
PnorKRTiES. — Charcoal of good quality burns slowly in the air, without flame; it
is clean, hard, compact, brittle, sonorous, and of a fine black color; its fracture is
shining, irridesccnt, and of a conchoidal form.
When not perfectly charred, it is tough, of a grayish color, and burns with a white
flame and smoke. When too much burnt, it is of a dull black, soft and unelastic. By
exposure to the air, charcoal absorbs from 10 to 20 per cent, of moisture, and its
qualities are thereby impaired ; it should, therefore, be kept under cover.
Pit Coal.
BiTUMixous COAL. — There are two principal varieties.
Opcn-hurniiKj coal kindles quickly and burns well, but produces much flame and
smoke, and is soon consumed; it lies open in the fire, and does not cake. Of this
kind is the English cannel coal.
Closc-hurninij coni melts and swells in .the fire and runs together, forming what
blacksmiths call a hollow Jire, or a dome over the nozzle of the bellows, under which
the iron is heated equally and covered from the air. This kind of coal forms a very
hot fire and leaves little residuum : it is, therefore, the most suitable for smiths' use.
The Newcastle coal and the Virginia, Maryland,. North Carolina, and Pennsylvania
bituminous coals are of this kind.
Anthracite coal is now extensively used for the forge, in fireplaces specially
contrived for the purpose. It ignites with difficulty, and does not cake or melt in
the smallest degree, but produces a very hot, open fire.
Coal is not injured, but, on the contrary, rather improved, by exposure to air and
moisture.

TAR. PITCH. TIRPEXTIXE.
The following arc (he principal varieties of products from resinous trees, such as
the pine :
TiRi'KSTiXK. — This is extracted from the tree in warm weather, by cutting a deep
notch, or h>ix, neiir the base, and (^coring the tree by scraping off the bark above the
box ; the first year's running produces the rinjin <ir irhitt turfienltne, and the second
year's is nearly as good ; after thut the turpentine becomes each year darker and
sitiffer, the tree yielding less of what is called f/iy/;.i'M(/», and more irmpiny ; the latter
kind of turpentine is hard and yellow. A tree will bear tapping fourteen to sixteen
years, on two sides alternately — the scoring being extended upward from twelve Ut
fifteen inches each year.
Spirits of TrRi'ENTiSK is the esuential oil obtained by distillation from tLe iiutire
turpentine.
Rosis, OR Colophony, is the residuum of the distillation of turpentine. Its quality
depends on that of the turpentine, and on the care used in distillation: the finest
quality is of a light straw color.
Tar is obtained from the heart of the pine tree by *mr>uldering. or a smothered
combustion, effected in stacks, nearly in the manner described for making charcoal.
The tar runii off into tjH;nches dug for the purpose. Tar is semi-fluid, transparent
in thin portions, and of a reddish color: it has a strong, peculiar odor. It is ren-
dered more fluid by heat ; and it burns with a bright flame, leaving a light and dry

coal. It is refined by heating it in an iron vessel, and pouring it off, after it has been
kept for some time in a liquid state; by this means water and pyroligneous acid are
driven off, and the earthy particles are separated b}' settling.
Itris used for coating cordage, and for wood which is not to be immersed in water.
PiTcn is made by boiling tar down to the requisite consistency, either by itself or
combined with a portion of rosin; it becomes solid on cooling, but is soon softened

The weight of dry atmospheric air at the temperature of 32°, the barometer
being at 30 inches, is l-770th of that of distilled water.
The weight of a cubic foot of distilled water at the maximum density being nearly
1,000 ounces avoirdupois, the specific gravity of a solid or liquid body expresses
the weight of a cubic foot, in ounces ; therefore the weight of such a body in
ounces will be found by multiplying its contents in cubic feet by its specific gravity.
According to Mr. Hassler's comparisons, the weight of a cubic foot of water at
its maximum density, the barometer being at 30 inches, is 998.068 ounces.
According to the British imperial standards, the weight of a cubic foot of water
at 62°, the barometer being at 30 inches, is 997.136 ounces ; this would give for the
cubic foot of water, at the maximum density, 998.224 ounces.

This <« found convenient in weighing rmall lampleH, to avoid plating numerona
waightJ on the pan. One inch of the in<lex-»tem dinplaeei one grain of water.
The pointi of the .silver wiren arc placed .1 and .3 inch apart, reipe<>tiTely, and are

Reporlh of KxperimenU> on Metalu for Cannon, by Ordnance OAcTra.
The instrument ii< at its lero when one of the pointu of the »et of wire* nearaat
eaeh other is above, and the other below the surface of the water: when either
touches the water, the load is 1-lOth of a grain too light or heavy. If either o(
the two points which are more distant from the lero touch the surfaoe of the water,
the load is too heavy or too light by S-lOths of a grain; if the heel of either of
these parts touch llie surface, the error is 4-10lh» of a grain.
The water for the hydrometer is contained in a glaas jar 25 inches deep and not
less than 12 inches in diameter. The height of the water in the jar should be such
that when the bottom of the hydrometer descends to the bottom of the jar the
weight pan shall be one-quarU-r of an inch above the surface of the water.
A thermometer divided into degrees and quarters of a degree is mspended in the
water while wcij;hing samples, and the temperature is noted at each weighing.
To UsK THK HrDROMETKR. — Load the pan with the grain-weights until the in-
strument rests at its lero : note the weight required. Place the sample on the pan ;
add weights until the hydrometer sinks to its zero ; the difference between this and
the first wcijrht is the weight of the sample in the air. Place the sample on the
bulb of the instrument; immerse both until the hydrometer again rests at lero ;
note the weight on the pan. Subtract this weight from the weight of the sample
in the air, and the difference will be equal to the weight of water displaoed by the
sample.
WEIGHT AND STRENGTH OF IRON CHAINS.
423
Divide this last weight hy the number in the tahle, page 478, corresponding to
the temperature of the water at the time of weighing, and the quotient will give
the corrected displacement for the temperature of fiU°. The weight of the sample
in the air divided by the corrected displacement, gives the density of the sample.
Rain or river water may be used instead of distilled water, if its relative density
first be determined accurately and the proper correction be made.
The density of the same water at different degrees of temperature may be deter-
mined in like manner. The weight of water which the hydrometer displaces at any
other temperature than 60°, divided by its displacement in the same water at 60°,
gives the proportionate weights of water displaced by the same instrument at other
temperatures.
The table on page 478 docs not give the absolute density of water at different
temperatures, but only the proportionate weights displaced by the same glass bulb.
The varying bulk of the latter in different temperatures is not taken into account,
as it compensates very nearly for the varying bulk of the metals weighed in cor-
responding temperatures.

PHYSICAL DATA.
Working Power of Men and Horses.
Men. — K t'liiit nolilirr travels in 1 minute,
in common timo, 90 stcpg = 70 yards,
in quick time, 110 " = 86 "
in double-quick. ]40 " = 109 "
He uccu]iie8 in the ranks a front of 20 in., and a depth of 1.3 in., without the kna])-
sack ; the interval between the ranks is 13 in. b men can stand in a space of 1
Square yard. Avcrnjre weight of men, 150 lb? each.
A mnii IravclK, without a load, on level ground, during 8} boon a day, at the rate
of '.\.7 miles an hour, or 'Mi miles a day. He can carry 111 lbs. II miles in a day.
A ]>ortcr going short distances and returning unloaded, carries 135 ll>s. 7 miles a
day. He can carry in a wheelbarrow 150 lbs. 10 miles a <iay.
The maximum power of n strong mau, e.xcrted for 2} minutes, may be 8tal«d at
18,000 lbs. raiscMl 1 foot in a minute. — }fr. Field'* ejcperimmtt, 1838.
.K man of ordinary strength exerts a force of 30 lbs. for 10 hours a day. with u
velocity of 2i feet in a second = 4,500 lbs. raised 1 foot in a minute = one-ji/tk the
work of a horse.
Daily allowance of water f')r a man, 1 gallon, for all purposes.
Horses. — A hum, travels the distance of 400 yards, at a walk, in 4i minutes; at
a trot, in 2 minutes ; at a gallop, in 1 minute.
He occupies in the ranks a front of 40 in., a depth of 10 feet; in a stall, from 3i
to 4i feet front ; at picket, 3 feet by 9. Average weight of horses, 1.000 lbs. each
A horso carrying a soldier and his equipments (say 225 lbs.) travels 25 miles in a
day (8 hours).
A pack-horte can carry 250 to 300 lbs. 20 miles a day.
A. draught -korte can draw 1.600 lbs. 23 miles a day — weight of carriage in-
cluded.
Artillery horses should not be made to draw more than 700 lbs. each, the weight
of the carriage included.
The ordinary work of a horse for 8 hours a day may be stated at 22,500 lbs.,
raised 1 foot in a minute.
In a kortf-mill, the horse moves at the rate of 3 feet in a second. The diameter
of the path should not be less than 25 or 30 feet.
Daily allowance of water for a horse, 4 gallons.
Ventilation. — A. man exhales ubout § of a cubic foot of carbonic acid in an
hour, or 15 cubic feet in a day. He produces from the lungs and skin about GOO
grains of rapor in an hour.
VELOCITY OP SOUND.
439
Air is no longer fit for combustion or respiration when it contains 4 per cent, of
Its volume of carbonic acid.
A ventilation of 8 to 9 cubic yards per hour fur each person is in all cases suf-
ficient. For barracks, a capacity of 13 to 20 cubic yards per man is suflScient; the
air being renewed in part by the cracks about the windows and by the opening of
the doors.
In dormitories the volume of carbonic acid does not exceed three or four thou-
sandths of the whole space, and the air is not more than J saturated with moisture.

The unit of lient is the quantity of heat necessary to raise the temperature of 1
lb. of water at its maximum density 1°.
Specific heats of substances are in the inverse ratio of their atomic weight.
The specific heat of a substance is called its capacity for heat. The capacity for
heat increases with the temperature, and diminishes as the density of the body
increases. Air reduced rapidly to one-fifth of its volume evolves heat enough to
set fire to tinder.

The heating power of different kinds of wood (taking equal weighu of wood
equally dry) does not vary more than in the proportion of 13 to 14, for the
extremes.
Nearly six times as much heat is required to evaporate a given quantity of w«|«r
as is required to raise its temperature to the boiling point: multiplying the aboTC
numbers by 6, we have, therefore, the quantity of water which each kind of fiMl
will raise from 32° to 212°.
In even the best apparatus, not more than hnlf the heat produced by the combov
tion of fuel is economized. j
Dry wood makes a hotter fire than equal weights or volumes of green wood. >

Sun-Dials.
The most common dial is that in which the plane of the dial is horizontal, and
the stijJf. placed in the meridian, is inclined to the plane of the dial at an angle
equal to the latitude of the place.
Hour-lines are drawn from the centre, or point where the style intersects the
plane, to the circumference: their positions are calculated from the formula tan.
ar^tan. // sin. L, in which ar = the hour-angle on the horizontal plane A =s 15",
30°, 45°, etc., the hour-angle on the equatorial plane, and L ^ the latitude of the
place.
To determine these lines geometrically, draw in the meridian plane from soBC
point o, on the style, a line perpendicular to the style, and note the point h where
it intersects the plane of the dial. Draw through this point a line, in the plane of
the dial, perpendicular to the meridian plane. This will be the equatorial line.
FORMULA IN MECHANICS.
447
Measure off from b, on the prolongation of the meridian, the distance b c equal
to a h, and with c as a centre, describe a semicircle, and divide it into 12 equal
parts, 0 on each side of the meridian : through these points of division draw radii,
and prolong them till they meet the equatorial line. Join these points of intersec-
tion with the foot of the style, and these lines will mark the hours before and after
12 o'clock, M.
To determine the meridian line without the ukc of astronomicul ingtruments. Take
a point in the plane of the dial through which it is intended the meridian plane
shall pass. With this point as a centre describe several concentric circles. Fix a
straiglit pin in the centre, perpendicular to the plane of the dial, of such a length
that the extremity of the shadow cast by it shall fall within the circles at 12, m.
Mark the points where the extremity of the shadow passes over these circles in the
forenoon, and again the same in the afternoon. The line drawn from the middle of
these arcs contained between the points of passage, to the centre of the circles, will
be the meridian.
Or the meridian may be determined by two plumb-lines made to cover each other,
and also the north star at the time of its passage across the meridian.
The time given by the dial is true solar time : to reduce it to mean, or clock time,
the equation of time must be added or subtracted.

FORMULA IN MECHANICS.
Forces acting on machines arc compared to weights, and are expressed in pounds.
The velocity of a body, the space which it passes over in a second of time when
it is moving with a uniform motion, or the space that it would pass over in a second
of time when it has a varied motion, if its motion should become uniform at the
time it is considered, is expressed in feet.
Uniform Motion.— Is expressed by ^= V T.
S being the space passed over, V the velocity, and T the duration of the motion.

If the balance be not accurate, the true weight of a body may bo found by taking
the squoro root of the product of the weights which counter|>'.ise it successively in

balance is to place the body in one scale and counterpoise it by any weight* in the
oppo.'iito scale: then remove the body and replace it by known weighix until tbe
equilibrium be a;;ain restored. The sum of the latter weights will be that of the
body rc(iuircii.
Friction.
In the foregoing conditions of equilibrium of machines, no aceoani Is takwSf
the resistance caused by friction, and by the stiffness of ropes, chains, etc.
NuiiuTous experiment.'' on friction have been ma<ie in France by M. Morin, frOB
which the following general results are obtained :
1. Tbc friction of any two bodies in motion is proportional to tbe pressure,
whether the surftt<"es be dry or covered with an ungiienL The ratio l>etweeo the
pressure and the friction is called the coejfirieui o/ /rtriinn.
2. The amount of friction is independent of the surface of rontact and of tbe
velocity of the motion. It depends only on the pressure, tbe nature of the surfacei"
in contact, aud the kind of unguent interposed.
5. In general, friction is less between bodies of different kinds than betwesa
those of tbe same kind.
4. When two surfaces have been long in contact at rest, an adhesion takes plaee
between them, the force of which is proportional to the ext4.-nt of the surface of
OODtact, aud independent of tbe pressure.
6. When a continuous stratum of an unguent is constMitly iat«qp«a«4 between

m
tl.c surfaces of contact, the araonnt of friction .lepen.U on the nature of the
unguent, and not on that of the surfaces.
6. With the unguents hog's lard and olive oil, the coefficient of friction is nearly
the same for surfaces of wood moving on metals, wood on wood, metal on wood
and met.al on metal. '
The coefficient for the unguent tallow is the same, except in the case of metal on
metal, for which it appears to be less suited than the others, giving a coefficient of
about 0.10.
7. The friction of axles is generally a little less than that of plane surfaces under
similar circumstances. The amount of friction is here also proportional to the
I>rcssurc. and independent of the velocity of the motion.

A horse-power in steam-engines is estimated at 550 foot-pounds per second, or
33,000 foot-pounds per minute, or 1,980,000 foot-pounds per hour. The average
power of a draught-horse as given above is 432 foot-pounds per second = 0,785 of
the conventional lioree-poirrr.
The French horse-power is equal to 542J foot-pounds per second, being about
l-70th less than our horse-power.

Pressure of (lunpoicder per square inch.
(From Captain Roiliiian's Kx|>erimpnt«.)
The pressure on a 42-pounder gun, at the bottom of the bore, when fired with 10
pounds (if powder and a solid shot weighing 4.3 pounds, i^ 44,J35 lbs.
8 lbs. of powder of a grain .1 inch diameter, with the same gun and shot, gave ■
pressure of 51,800 lbs.
8 lbs. of powder of a grain .4 inch diameter, with the same gun and shot, gave a
pressure of .31,900 lbs.
12. fit lbs. of powder of a grain .6 inch diameter, and a solid shot, weighing 186.3
lbs., fired from iin 11-iueh gun, gave a pressure of 21..H70 lbs.
' The same weight, of ..1 inch diameter, gave a pressure of S.O.SSO lbs.
The same weight, of .3 inch diameter, of different powder, gare a pressure of
65,920 lbs.
Half the weight t)f powder, of the ordinary charge, with double the weight of
shot, gave the same pressure as the ordinary charge.
1 lb. of powder, burned in a space equal to twice that occupied by the powder,
gave a pressure of 42,500 lbs.
2 lbs., burned in the space occupied by it. gave a pressure of 133.590 lbs.
1 lb., burned in the space occupied by it, .1 inch grain, gave a pressure of 185,000

The trajectory described by a heavy projectile thrown with a low Telocity, as in
the case of an eprouvette ball, approaches very near to a parabola. If the projec-
tile be light for it^ volume— as is the case with shells— the trajectory described is
not 80 near; and when higher velocities are employed, the trajectory is rery differ-
ent, and it is necessary to take into consideratiAi the resisUnce of the atmosphere.
BALLISTICS. 465
Resistance of the Air.
When a body moves in the air witli a low vclocitj', of 25 to 30 feet per oecond, it
meets with a resistance wbii'h is sensilily proportional to the density of the air, bo
the area of the projection of the body on a plane perpendicular to the direction of
the motion, and to the square of the velocity of the body.
The resistance of the air in pounds = ^^ '•■ o ^ ^'
^ being the weight of a cubic foot of air, and k a coefficient, constant for similar
solids, but varying with different forms.
When the body moves with a high velocity, the resistance of the air increases in
a more rapid ratio than the square of the velocity, and the law may be ex])ressed by
adding a term proportional to the cube of the velocity.
For spherical projectiles the resistance is in proportion to the area of a great cir-
cle: calling the radius It, the velocity r, the resistance of the air, in pounds, p, it
has been found that
p = j4 "T 7i'2 f2 1 1 -|- — I, in which .-1 is the resistance per square foot of cross-
section for a velocity of 1 foot per second, and r is the velocity for which the resist-
ance due to the second term is equal to that due to the first.
E.\perimcnts in France with guns and solid shot hare shown that for a mean den-
sity of the atmosphere of ^.^^ part of water, and for ordinary velocities, with spher-
ical projectiles, A = .000514 and v = 1427 ft.: for shells with low velocities, as from
mortars, r = 2735 feet.
Motion of a Projectile in the Air.
The noyiiKil trajeclori/ in the air is a continuous plane curve, which can be cut by
a right line in not more than two points; it has two asymptotes, one vertical, the
other inclined.
The actual trajectory of a ball is generally a curve of double curvature. It dif-
fers from the normal trajectorj' in consequence of the deviations, both lateral and
vertical, produced by the eccentricity of the ball, its position in the gun, the
motion of the air, and other circumstances, which cause the ball to revolve about
an uncertain and variable a.\is and to depart from the vertical plane of projection.
The equation of the trajectory is a complicated one, and difficult of computation.
(Jeneral Didion has reduced it to the simplest form.
Adopting the same notation as in the motion of a projectile in vacuo, and desig-
nating by Fj ^Fcos. (p, the horizontal component of the initial velocity, a the

A may probably, without .sensible error, be regarded a.s constant for the same
quality of powder, though used in different kinds of ordnance; but the value of T

According to the experiments made with the Ballistic Pendulum at Washington
Arsenal, the mean values of the coefficients / and <^. for Dupont's powder, in guns
of variou.s calibres (from 6-pounder to .32-pounder). are: 7= .S,500 feet; A =

The above formuls^, for the resistance of the air and for the initial velocity, are
obtained from the " Traite de Ralistique. par le General Didion, I860:" a work
which may be consulted for a full discussion of the theory of the motion of projec-
tiles, and the deviations produced by their eccentricity ^nd other causes.

RIFLE GUNS.
Very little has been said in this Manual relative to the Rifle guns, or their ammu-
nition, which have been in use during the existing war. Of all the calibres thus
far tried, the 2J-in. Mountain Rifle, the .3-in. field piece, and the 4.62 siege piece
only, have been incorporated into the service calibres. It is more than probable,
however, that even these last will be superseded by the 10-pdr., 20-pdr., and 30-pdr.
Rifled guns of Mr. Parrott, which, with their peculiar ammunition, have given
very good results in the field. A number of them have, accordingly, been directed
to be fabricated.
The Whitworth breeeh-loading Rifle cannon, of which half a dozen are in service,
is steel, with a wrought-iron band at the breech. The breech screws off and works
in a collar turning on a hinge. The calibre of the inscribed circle is 2.71 inches.
The sides of the hexagon have one turn in il^ /net. The projectile is a hexagonal
prismoid in form.

The range of 3-inch Rifle gun, with 7, or 11, or 13 grooves, does not vary mate-
rially from this up to 2,300 yards— 6° elevation giving 2,250 yards.
The Armntrong Gun is a breech-loading Rifle cannon, made of wrought-iron tubes
welded together ; each tube is from two to three feet long, and is formed by twist-
ing a square bar of iron around a mandrel, and welding the edges together, as a
good fowling piece is made. In the rear of the trunnions it is enveloped with two
additional thicknesses of tubes. The outer consists of a spiral coil, but the inner
is formed of an iron slab bent into a circular shape and welded. This intermediate
layer has chiefly to sustain the pressure on the bottom of the bore.
lireech.— The breech is closed with a vent piece, which is slipped with the hand
into a slot cut into the breech of the piece, and held in its place by a breech screw,
which supports it from behind. This screw is made in the form of a tube, so that
its hollow forms a part of the bore prolonged, when tbc vent piece is withdrawn,
and through this hollow tube the charge is passed into the chamber.
Jiore.— The bore of the field gun is three inches in diameter, and is rifled with
thirty-four narrow grooves. Twist, one turn in 9 feet.
Projectile.— It consists of a very thin east-iron shell, enclosing forty-two seg-
ment-shaped pieces of cast-iron, built up so as to form a cylindrical cavity in the
centre. The exterior of the shell is thinly coated with lead. The lead is also

allowed to percolate among the segments so as to fill up the interstices, the central
cavity being kept open by the insertion of a steel core. In this state the projectile
is so compact that it may be fired through six feet of hard timber without injury.
while its resistance to a bursting charge is so small that less than one ounce of
powder is required to burst it.
