r two pieces of iron, and from a tinman how to solder tin or copper. In the absence of this experience, a man who is determined to help himself need not despair of

anner. In using the hammer, some care is needful to proportion the force of the blow to the size and comparative heat of the metal you are working, and also to turn the iron under the hammer so that each stroke shall help to consolidate the mass instead of splitting it into fibres. When the surfaces of the scarf are worked smooth, fair, and perfectly free from scales or dirt of any kind, place them side by side in the fire and bring them to an intense white heat, so that when drawn forth they may almost spontaneously give off small white sparks. We would add a caution against burning the iron, or partially fusing it, by too much heat, but we do not think a traveller with an extempore forge is in much danger of doing this. The anvil should now be perfectly clean; the "smith," with his hammer ready in his right hand, should grasp with his left one of the pieces while his attendant draws out the other and lays it with the scarfed side uppermost on the anvil; prompt action without hurry is now the one thing needful: the smith withdraws his piece, lays it with its scarf turned downwards on that of the assistant's, and with one decisive stroke of the hand-hammer unites them; a few more smart and rapid strokes while the iron is

and ho

it, as can the framework of hut roofs. A piece a couple of yards long, doubled forward and back in zigzag form, makes an excellent gridiron. Short pieces, straightened out by hammering, form useful make-shift knife blades for the use of native servants. Tent poles are greatly strengthened by having a spiral strapping of this iron nailed to them. Saws for cutting or rather fretting blocks of stone can be made by stretching a strip of this material edgewise in a wooden frame, aided by water, sharp sand, and a suitab

actory to the eye, is in itself stronger, as the inequalities, flakes, flaws, or roughnesses of the surface, which, under any strain, might form the commencement of a fracture, are removed; and besides this, especially in

ld or of join

sel may be used without more injury than may be set right by fresh grinding it; it is advisable, however, first to render the angle at which

and

ourse is to cut and shorten the tire, for all other make-shifts have the disadvantage either of being insecure, or positively injurious to the fabric of the wheel. Supposing the shortening to be determined on, the tire must be taken off, and if, as is frequently the case, it be fastened with rivets through the felloes, the clinch on the inner ends o

way; and in this case it is proper to estimate whether the felloes will close up sufficiently to force the spokes home upon the nave; if not, the ends of four or more felloes opposite each other should be cut a trifle shorter with a fine tenon saw, great care being taken not to cut the dowels by which the ends of the felloes are kept true to each other. A smooth, hard place must now be sought out, on which the wheel can be laid flat, the front downwards, a hole being dug, if necessary, for the reception of the nave; flat stones, plates of iron, or slabs of hard wood, laid evenly under the circumference, would be of advantage when the shortened band is to be driven on. The next essentials are plenty of water and abundance of heating power. The ends of the band must now be heated, and the smith will bevel off each of them, one from the inside and the other from the out, so as to form the scarf; an attendant or two holding the band, as he directs, upon the anvil. The tire should now be reversed, and the curvature increased by resting it on two points of support and striking heavily between them on its inner surface till the scarfed ends close upon and begin to overlap each other. It is again placed in the fire with the ends equally exposed to the intense heat, and at the proper moment is lifted out by two attendants

No part of the waggon ought to be used as a holdfast for the vice, unless indeed it were properly fitted with iron guards for that purpose before starting, for the claws and screw-bolts would speedily tear and split the wood, and only damage the vehicle to no purpose.

follows:-One of our small mining picks chanced to have an iron wedge (which had originally been cut from an old patten iron) in the handle. This we softened in the fire, worked into form on the head of an upturned hammer with one of smaller size, and then roughly finished it up with a handsaw file. The screw hole had then to be made, and, as we had no drill, we took the scissors from our fishing-book, ground do

eft and the front sight (Fig. 7) to the right; if to the left, shift the back sight (Fig. 8) to the right, and the front one (

heck for the bayonet (Fig. 11). We did not remove this, but cut behind it a very shallow groove an inch broad, and in thi

e was turned beneath the barrel (Fig. 12), and the little flat thongs of antelope hide were not at all in the way. With guns not of military pattern the sight could not so conveniently be turned under, but would have to be removed by day; but we should think a broad silver sight might be fixed on a steel spring on the rib behind the sight, with a b

a little grease, intensely black; it is then very carefully cut, to allow the front sight to appear through, and left to dry. Another advantage of this plan is, that it corrects the errors often caused by the mirage or refraction of the sun's rays from the

nives or

nife, of from 6in. to 12in. in the blade; and the handle of this ought to be made so that it may fix as a bayonet on his gu

thodox triangular needle, that is only of use in opportunities that occur but rarely. We remember a party of a certain line regiment coming upon a number of Hottentots, when their officer ordered them to fix bayonets, forgetting for the moment that as usual they had been left at home-just as were the swords and steel scabbards of the Cape Corps-lest their rattling should give warning to the crafty foe.

The requisite length was then cut off; the end flat

The cold chisel is first forged to a chisel edge, more or less finely tapering according to the strength required, the two sides forming an angle of about 15° to 20° with each other; the cantle is then filed or ground till its sides form an angle of from 45° to 90°; it is then heated to a cherry red, and dipped in water cautiously at first, being frequently taken out and watched during the process till it assumes a pale straw colour, a deeper tint or even a deep blue or purple, according to the degree of hardness required, and is finally ground sharp upon a stone with plenty of cold water. Small tools may be

to file or saw them through; if of steel, a blow with a stone, or any other heavy substance, would break them as though made of earthenware. When case-hardened neither of these devices is available. Too hard to cut, too tough to break, the metal is all that can be desired. Having fashioned, filed up, and finished the article or articles in hand, procure a fair quantity of leather cuttings, or horsehoof parings. These should be roasted crisp, and pounded up until a sufficient quantity of coarse powder is obtained to bury the "work" when laid in a little iron box, which can be conveniently made by doubling up the edges and ends of a bit of sheet iron. In the absence of iron, clay may be used to form the box. This, when filled and gently pressed do

For this purpose they may be suspended, by means of a fine wire, over a spirit or an oil lamp, in such a way as not to touch the flame. Suddenly, before they have had time to cool, the objects are to be completely plunged beneath the surface of the platinising liquid. One immersion for a single minute generally suffices, but the process may be repeated if necessary, care being taken to wash and dry the pieces operated upon before re-heating them. The composition of the soluti

They are then withdrawn, wrapped in blotting-paper, and kept in a warm place till the excess of paraffine has

We have, before now, broken up a gridiron at the galley fire, and with a hook thus formed from one of the bars caught a young shark, whose flesh formed a very desirable addition to our fare.

most, a slightly overlapping double thickness may be left at top and bottom (Fig. 8). The bottom edge is now turned outwards by gently tapping it on the block or anvil edge with a hammer till it resembles a narrow flange (Fig. 9). A circular piece is now cut for the bottom so much larger as to allow a rim to be turned up all round (Fig. 10), and to admit the flange within it (Fig. 11); then setting it flat upon the anvil, and forcing into it a block of wood that has been cut perfectly to fit it, clinch down the rim of the bottom upon the flange (Fig. 12), and turn them both up against the side together (Fig. 13). The top edge may now be rolled over in the same manner, and it will give additional strength if the rim is strengthened by the insertion of a piece of wire.

The great virtue of raw hide is that, instead of slackening like rope when it dries, it shrinks, and becomes as hard as iron. Suppose a dissel-boom sprung where another could not be procured, the skin from the leg of an ox, or a wild animal of corresponding size-say a buffalo or quagga-drawn on while wet and allowed to dry, would make the joint firmer even than the unfractured part (Fig. 8). The

These must be driven tightly in from back and front, between the felloe and the tire, and as equally as possible all round the wheel; if they are then wetted with, and allowed to absorb, a strong solution of salt in water, they will swell, and will not again shrink as they would if wetted with water only. We knew one very practical Englishman who used to soak his wedges in salt and water before driving them in, but what he gained by thus previously swelling them we ne

h well-kneaded clay, which has been carefully freed from stones or grit, pressing it well down with a flat board until it is quite even at the surface and is perfectly compact. The clay round the edges of the two clay holders must now be trimmed off with a knife even with the sides of the holders, but projecting about an inch beyond the brim. The surface of each is now to be sprinkled with very fine ashes, and the ball pressed into the centre of the clay until it is half imbedded. It is then to be carefully removed, and pressed in like manner on the other holder. The ball is then taken out and laid aside, the two holders being allowed to dry slowly, care being taken that the clay is not cracked by the too sudden application of heat. When thoroughly dry, the vessels or holders are to be placed mouth to mouth, and so fitted, by scraping the clay, tha

n rather short, we started for the tent to get more, desiring one of the Indians, who was keeping up the fire and generally aiding in the operations, to go on casting so soon as the moulds were cool. That no time might be lost, our dusky assistant plunged the hot mould in a pot of water, closed it up, an

a sharp point on each half, and scooped neatly out with a knife, chisel, or other convenient instrument; when finished, notched, and the inlet cut, the two halves are tied together with tape and the lead poured in. Objects of six or seven pounds weight can be made by the use of two common scouring bricks. Balls of large size are often made in the East by hammering square masses of lead, or iron, on an anvil until sufficiently round for use. Great labour and no little skill are required to perform the operation, w

d in the same manner. The shot, when cold, are cut from their necks with a knife or strong pair of scissors, and are then fit for use. They should be about the size of common peas, and a charge of them from a large powerful gun is tremendously effective; they are extremely useful for deer jumping, antelope shooting, wild goose or bustard stalking. At very short distances, and in close encounter

ine, must be so treated with a charge of molten lead that all the cuts are filled with it from the upper end; the result will be the formation of a great number of long lead wires. These are to be taken from the grooves and fresh batches run, until as many pounds have been made as it is intended to make shot. A preserved-meat tin, or an ordinary tin pot, must now be about one-third filled with water, and the remaining two-thirds filled up with oil; the pot must be placed on a plate or dish, in order to catch any oil which may run over as the work proceeds. The end of the iron bar which has the hole in it is now to be placed in the fire and heated to a bright-red heat: when the other end, round which a piece of cloth may be bound, is grasped with the left hand, and the bar quickly withdrawn from the fire, struck smartly against some solid body, in order to remove adhering dust and ashes, and then held with the wide mouth of the hole upward, a short distance above the surface of the oil in the pot. A lead wire is now to be quickly taken up in the right hand and its end pressed well down into the hole (as shown in the above illustration); if the iron is well heated, the wire will melt away very rapidly and run in a succession of drops into the oil: wire after wire is to be thus melted, until the iron requires reheating. (It is a good plan to have two or more irons at work, but it is not essential.) This wire-melting process must

Remove the cork and clay, and fashion from strong hardwood a rod just long enough to reach a few inches beyond the indentation. A bar of iron is now to be heated to a red heat, and placed against the indented spot on the outside of the barrel; the wet cloth being at the same time w

ramrod or loading stick should be very deeply countersunk, in order to take all pressure off the cap; and even with this precaution it is well to make use of an overhanging branch of a tree to place the rod against, whilst the rifle is thrust muzzle upwards until the ball is home. Shells somewhat on this principle were first brought into notice by the late General Jacob, of the Scinde Irregular Horse. They are tremendously destructive when skilfully used: destroying large animals by exploding in them, and blowing up magazines of gunpowder at all but incredible distances; but we have known them explode outside the elephant and other large pachyderms, thus failing completely in the object they were used for. Mr. Metford's improvement on the Jacob shell is worthy of remark. Finding that it did not always explode, he mixed equal parts of chlorate of po

prepared; on one end of this a spoon-shaped cavity, with a lip-shaped groove in the end, is made; in the bottom of this a few red-hot wood embers from the fire are placed on these same fragments of flattened lead, and on the lead some good-sized pieces of red-hot embers. A bit of b

Then on the bottom or floor of the stump a thick layer of dry wood is placed, evenly on this a layer of the powdered ore, then another layer of wood, then one of ore, and so on until the stump is quite full. A small hole is then chopped with a tomahawk through the sid

A bullet cleft very nearly through with two cuts, so that it spreads into four parts (Fig. 2), makes a fearful wound at close quarters-a conical cut from its base (Fig. 3) particularly so.

h-loader, the simplicity and strength of which, combined with facility of loading, were all that could be desired, unless, indeed, it were made self-capping, which we believe could easily be done. A metal breech-plug, to be inserted when required, converts it into a muzzle-loader; but then a smaller size of bullet must be used, and the cartridges are so simple and inexpensive, that we found it more easy to make them on the spot. The materials required were a few sheets of tissue paper, a quantity of felt wads, tolerably stout, half of them the exact size of the bore, and the rest a little smaller. A piece of tin of the form and size indicated by the diagonal lines (Fig. 1) in our illustration was used as a pattern by which to cut the paper. The straight edge that was to surround the bullet, and the farthest diagonal side, were touched with a little gum, gathered from the nearest mimosa. A small cylinder of wood (Fig. 3) was then taken by the knob, in the left hand, and, with the right, the hollow base of the bullet (Fig. 2) was fitted on to the convex end, laid fairly on the paper (Fig. 6) and rolled forward until the cartridge case was formed. The wood was then withdrawn, and the paper, adhering to the bullet, left to dry. When a sufficient number were completed, they were set upright in any convenient trough, or in a block of wood (Fig. 7), 3in. deep, bored with holes of the proper size (Fig. 11). The charge of powder was poured into each and covered with a small disc of card or paper. One of the small wads, saturated with grease, was next put in (Fig. 8), t

Secondly, take the roller and return it to the case, excepting that you leave the roller exposed at the top, say for 16-gauge about ?in.; place the case and roller in the chamber, bottom upwards, then take some fine strong twine and place round as in drawing No. 1. When drawn tight, tie firmly, and it will appear as in No. 2: then reverse the roller and case, bringing the tied end down to bottom of chamber, press down hard to flatten the bottom of case, draw out the roller, pour into the case some melted tallow of about the consistency of cream, and t

The cartridge is now complete, and can be cut off next the stick, when you proceed as before until all the tube has been used. We manufactured a great number of these in Tartary, and found them hard-hitting and durable. We usually carried a waistcoat pocket full of them, and rammed one down on each charge of powder without any wad between the cartridge and powder, but always placed one over the cartridge, in order to prevent it from rising in the barrel.

The ramrod will also at times get firmly fixed in a foul barrel, and defy every ordinary effort to get it out. A little water, spirit, or any other fluid poured down the barrel almost instantly releases

it. These, when cold, are set aside for use. When placed on the nipple, the wax forms a shield between the cap and nipple, which prevents the water from working its way up. All vegetable oil used about gun-lo

is no danger of ignitable threads being left behind, and it can be used repeatedly by washing and drying it. When the barrels are thoroughly clean, fill them with boiling water. When this has all run off through the nipple holes, commence with a fresh strip of cloth to dry out the barrels, which must be held in a folded cloth, in order to guard the hand from the heat of the water.

Below the lens we fitted a piece of tin with its edges turned downwards, to hold a piece of quick match, a strip of calico, steeped in a strong solution of gunpowder, beneath it; a small slit in the tin was then so adjusted as to let the focus of light fall through it exactly at 12 o'clock; a small clip of tin confined the other end of the match over the vent.

This answered admirably; but our next fear was that the supply of matches would run short, and therefore, drawing on our own artificial horizon for the quicksilver, on the photographic stores for nitric acid, and on our friends, the missionaries, for a supply of alcohol from their natural-history department, we set about the manufacture of fulminate of mercury according to the following recipe:-Dissolve 10 grs. of mercury in 1? oz., by measure, of nitric acid; the solution is poured cold into 2 oz., by measure, of alcohol in a glass vessel, and gentle heat is applied till effervescence is excited, though it ordinarily comes on at common temperatures, a white vapour undulates on the surface, and a powder is gradually precipitated, which is i

he substance of the cartridge aids much in keeping its form and facilitates loading. A cartridge needle should be used to perform this operation. This needle can be easily made from a piece of stout copper or brass wire. Flatten out one end, drill or punch a hole in it to form the eye, and file the other end sharp for a point. Fourteen inches is a convenient length for a cartridge needle.

It is far better to keep on hand a few priming cups. These are made as follows: From the joints of a bamboo cut a number of little cups, the bottoms being formed by the kn

fast with twine. When the gun is to be fired, the cartridge is pierced in the usual way with the priming wire. The tube of the priming cup is now to be inserted at the mouth of the vent, and pressed down until the bottom of the cup

The saddle was originally constructed of two-forked branches connected by wooden bars, and if the gun was slightly overloaded the recoil would injure the fittings, and disturb the animal; but subsequently the saddle was much improved, and wheels were added, so that it might be taken from the animal's back and used as a field gun. It will be seen that the staff of the bannerol carries a little tent, and this covers the ammunitio

round the quill, which is filled with meal powder. The case and quill head are then capped with paper which has been soaked in dissolved gunpowder or nitre. Arrows thus made are to be fired from powerful hand-bows, after the match has been lighted. In the true rocket arrow the touchpaper is ignited

der, t

educed to perfect powder, quite free from lumps or grit. The three powders are to be now weighed out carefully in the following proportions: One part sulphur, one part charcoal, and six parts saltpetre. Mix these on a skin pegged out on the ground, and rub the mixture together with the palms of the hands until most intimately and thoroughly blended; then, with an empty percussion-cap box or drinking cup, measure your mixture, and for every ten cups or boxes of powder put down a stone or make a mark, and for every mark put aside a cup full of warm water, so that you have just one-tenth of fluid. This you sprinkle with a bunch of feathers or grass, a little at a time, on the powders, until, by constant and persistent working and kneading, a smooth homogeneous paste is formed. Two well-selected stones much facilitate this stage of the process; one should be large and flat, the other water-rounded and oval; in fact, a water-worn pebble of about 2lb. weight. By sitting on the stretched skin with the flat stone between the legs, the water and sprinkler at the side, and the pebble between the hands, the paste can be effectually worked up; and it is well to bear in mind that on the perfect homogeneity of this paste depends, in great measure, the quality of the gunpowder. The paste-or devil as it is sometimes called-being thoroughly elaborated, make square flat cakes of it 6in. square and 2in. thick, and wrap them compactly up in cotton cloth or old sheeting four or five times doubled; then stitch up a stout hide bag just large enough to contain all your cakes and their coverings when built in compactly one on the other, and sew up the opening; then, with a chisel, scoop out a cavity in the end of a log just deep enough to half bury your case of cakes; then, with the aid of a neighbouring tree, and a few suitable pieces of wood, which are easily fashioned with the axe, prepare such a press as is shown in the above illustration. The weight should be increased gradually, and the pressure intensified until the cakes are pressed in

in which it resides, and, water borne, travels onward until arrested by some deep pit or crevice in the river bed, where it remains until disturbed by floods of more than ordinary magnitude, or the pick and shovel of the miner. Our space will not admit of our dealing at length with the indications of gold or other metals, or of the regions in which the precious metals and gems are to be sought. We shall, therefore, content ourselves by giving a few plain, and we trust practical, hints for the finding and identification of such metals, stones, &c., as the traveller is likely to meet with. First in importance we class gold; and, although precarious and uncertain in the bulk of its deposits, is more generally distributed throughout the earth's surface than any other metal. Clay slate formations, traversed by iron-stained quartz dykes, are well worth investigating; and most of the streams which flow through such formations will be found, on careful examination, more or less auriferous. In prospecting a stream, or river bed, choose localities where th

nd miner

collects, it is removed with a species of scraper, fashioned from the end of an iron bar. A small rod or stick, with its end fibres frayed and set up like a mop, is used for drying out the hole. Should it be in wet ground, where moisture remains in spite of swabbing out, a cartridge composed of tallowed cotton or oiled paper, may be used to inclose the powder in. According to the old-fashioned plan, which some miners still follow, a long pointed copper rod or needle was pressed into the charge after it had been rammed into the bottom of the hole. Round this rod clay, pulverised clay, slate, &c., was closely packed, and driven with a copper tamping rod until the hole was compactly filled up. The needle was now withdrawn, and a match, composed of a long marsh reed filled with mealed powder, thrust down the orifice until the charge was reached, when the upper end was held in its place by

such other localities as miners are in the habit of examining. We therefore offer a few hints a

Fig. 7 consists of a conglomerated mass of quartz pebbles rounded through having been water-worn, a crystal of diamond, the size of a small pea, and various grains of gold, the whole cemented together by oxide of iron. This specimen is peculiarly interesting at the present time, as showing the association of diamonds with gold. In 1844 a slave was searching for gold in the bed of a river in the province of Bahia, and discovered diamonds. It being a new locality for diamonds, 297,000 carats were collected in

minated at each end by six-sided pyramids. When transparent, and of a blue colour, it is known in jewellery as the sapphire; when merely

your sapphire bites or scratches it, there is no hope of its being a diamond. If on weighing it the specific gravity of the specimen is found to be less than 3·9, it will not turn out to be a ruby or sapphire. The application of heat is another test, as if no electricity is manifested it will not turn out to be a gargoon or a topaz. If, on testing it on your piece of flint glass, the surface of that i

fe, turns its edge, and will strike fire against its back, giving out sulphurous fumes. Mundic, after being made red hot, is attracted by the magnet; gold never is. Hot nitric acid causes it to decompose with much effervescence, leaving such spangles of gold as it may contain free in the bottom of the test tube. Gold dust is readily taken up by quicksilver; mundic is not. Yellow mica is so much lighter than gold that its comparative want of ponderability should at once distinguish it; a small portion placed on an iron bar, and heated in the fire to redness becomes, on cooling, flakey and lustreless, whilst gold would remain unaltered; it floats on the surface of mercury, refusing to unite with it, whilst gold is immediately

As one piston man gets fatigued, another takes his place; thus a continuous stream of air is kept up. Whatever method of blast is decided on, it must be so arranged as to be continuous and powerful. When the interior of the furnace is quite dry, throw in a good quantity of well-burned charcoal; then a layer of split dry wood until it reaches about 1ft. above the entrance of the blast; then another layer of charcoal and dry cow dung a few inches deep; then sprinkle in loosely a layer of broken iron ore, mixed with a little limestone if you can get it; then another layer of charcoal and dry cow dung, and another of ore; and so on until the furnace is all but full, only one layer of wood being used. Now through the blast entrance introduce some well-ignited and glowing embers from your fire; put in the tube of your blast, which may be of baked clay; lute it fast in its place, so as to prevent any escape of air; and proceed to blow, when your furnace will soon be in a state of active ignition and glow. Keep up the blast steadily, and as the contents of the furnace sink down add to them from above layer by layer as before

r particle gives off a train of minute bubbles and gradually dissolves, pour a little of the contents of your tube into two separate watch glasses placed side by side, add a little water to each. Add a little common salt to No. 1; if the particle is silver, you will at once have a thick white precipitate-chloride of silver. Drop a few drops of your liquor ammonia into No. 2; and if copper, the beautiful and well-marked blue colour of ammonuret of copper will at once appear. Should the particle have crushed under the blow, it is probably either sulphuret of iron or copper ore. To distinguish these two substances when in a minute state of division, proceed with the acid as just described, and test one watch glass with a small fragment of ferrocyanide of potassium, when, if sulphuret of iron or "mundic," you will have a dense cloud of Prussian blue in your watch glass. Treat the other with your liquor ammonia, and you will have the same brilliant ammonuret of copper colour as if the particle had been native or malleable copper. Having satisfied ourselves as to the selected particles-for should the flattened grain resist the action of the hot acid and remain bright, it is surely gold-we place our sand on a shovel, and hold it there until the whole is red hot; it may then be taken from the fire, and allowed to cool on the shovel. The magnet will now take out all the bits of iron. Now with a hammer-face or smooth water-worn pebble proceed to crush all the substances on the shovel fine. Then at the nearest stream of water, or in a large tub, carefully van and wash your sample until all the earthy and worthless matters have been washed away; then the practised eye will instantly distinguish the gold, if any. The utterly inexperienced may, however, be deceived by remaining fragments of mundic or copper ore before referred to; therefore, to make assurance doubly sure, let him dry his washed metal powder on the shovel over the fire, then carefully place it in a small, clean, dry vial-bottle with a little quicksilver. Shake and rattle it well about until all the particles have been brought well in contact with the mercury. Such fragments as it will not take up are not gold; but to find that which it has converted into an amalgam, place the mercury in a piece of clean chamois leather, press it carefully, and the mercury will force its way in minute globules through the leather, leaving th

When large square or oblong blocks are required, it is well to first mark out the size required on the rock with the pick's point, and then with either the borer before described, or a jumping bar (of form shown in the annexed illustration), drill a row of holes about 8in. apart on the line before marked out, in depth proportioned to the intended thickness of the stone, in each hole should be placed a pair of gad cheeks-these are pieces of half-round iron bar.

Water swab, shell scraper, &c., are used with these implements, just as they are with the miner's borer, which can be used in confined spaces and under outlying works, where the jumper would be useless. A crowbar or two will be found very useful for lifting out broken pieces of stone, &c. There is also an instrument much used in America called a "canthook," which is here represented. It is extremely valuable for moving both stones of large size and logs of unwieldy dimensions. The handle, or lever, is made of tough, well-seasoned timber, and is usually from 6ft. to 7ft. long. The claw is of sound, tough, wrought iron, and proportioned in weight and spread to the bodies it is applied to. Two or th

The fire will then soon die out, and the contents of the pile can be removed. We also represent a contrivance for preparing
