A pole and bucket is a very convenient way of raising water from 4 to 12 feet. The bucket may be made of canvas, basket-work, leather, wood, or almost any other material; leakage, though considerable, is of little consequence, because the action of the apparatus is so quick, that there is not time for much water to be lost. This contrivance is used over almost the whole globe--less in England than elsewhere; it is very common where long poles can easily be obtained, as in fir forests.
Pump.--An excellent and very simple pump is used by the Arabs in Algeria. A piece of leather or waxed canvas, is stretched round one or more hoops; it forms a hollow cylinder, that admits of being shut flat like an accordion. The top and bottom of the cylinder are secured round the edges of two discs of wood. Holes are bored in these discs and leather valves are fitted to them. The lower disc is nailed to the bottom of a tub; the hole in it corresponds with the feed-pipe, and the valve that covers the hole opens upwards. The upper disc Is attached to the pump handle; the valves that cover the holes in this disc, open upwards also. When the leather-pump barrel is pressed flat, water flows through the upper valves into the barrel around it; when it is pulled out, water is sucked up through the feed-pipe, and an equal quantity is displaced from the barrel. This flows out into the trough. A bag would do as well as a tub, to hold the water which surrounds the pump-barrel; but, without the water which it is the object of either the one or the other to contain, the pump-barrel must be air-proof as well as water-proof. The action of this pump is marvellously perfect. It attracted much attention in the French Exhibition of 1855.
GUNS AND RIFLES.
General Remarks.--Breech-loaders.--At the present time when the merits of different kinds of breech-loader are so hotly discussed, when all that have yet been invented have some faults, and every month brings to light some new invention, it would be foolish in me to write anything about them; it would be obsolete before the great majority of my readers should have seen this book. Therefore omitting breech-loaders altogether from the present edition, I will confine myself to repeating what I have said before upon muzzle-loaders, with additions and alterations.
Size of Gun.--American bushrangers advocate a long heavy pea-rifle, on the plea of its accurate shooting, and the enormous saving in weight of ammunition when bullets of a small size are used. The objections to small-bored rifles are, insufficiency against large game (even with conical bullets), and a tendency to become foul after a few shots. A short light rifle, whether with a large or a small bore, is, I believe, utterly worthless. In the hands of a man trembling with running and with exhaustion, it shakes like a wand: the shorter the rifle, the more quickly does it oscillate, and of course, in the same proportion, is it difficult to catch the exact moment when the sights cover the object.
For the larger kinds of game, such as elephants and buffaloes, experienced sportsmen mostly prefer guns of immense Bore, carrying round bullets that weigh a quarter of a pound. The recoil is tremendous, and would injure the shoulder if the sportsman did not use a pad against which he rests the gun. The guns must be strong, because very large charges of powder are invariably used where great power of penetration is required. African sportsmen found this out experimentally long before the idea occurred to artillerists.
Sights.--The hind sight should be far from the eye, even though it be placed half-way down the barrel: else it becomes out of focus and indistinct, when the eye is firmly set on the object aimed at; this drawback is never compensated by the advantage of having the front and hind sights far asunder.
Ramrod.--The guns of servants and indeed those of their masters, should have thin soft-iron ramrods; the elasticity of these when slightly bent, will retain them in the ramrod-tubes; both ends of the ramrod must be forged broad.
