"But we don't want any water-towers," exclaimed a fireman; "we can make one ourselves, if we need one." That is, by using the fire-escape ladders to obtain points of vantage. We soon see this accomplished. With a rush of horses and a whiz of steam, a fire-engine tears into the yard, the steam raising the safety-valve at a pressure of a hundred and twenty pounds to the square inch. Off leap the men, as though actually at a fire; each one attends to his prescribed duty; and ere long you see one of the men hurrying up the escape-ladder bearing the branch in his hand--_i.e._, the heavy nozzle end of the hose. In a second the engine whistles, there is a spurt of water, and the fireman directs the jet from the distant head of the ladder to a tank in the centre of the yard. The beckets on the hose, placed at intervals of seventeen and then twenty feet, over a hundred-feet length, are made of leather; and are most useful for fastening it to a chimney or any point of vantage by means of the fireman's rope. The weight of a hundred-feet length when complete ranges from sixty to sixty-five pounds, and when full of water much more. The hose for the London Brigade is woven seamless, of the best flax; and the interior india-rubber lining is afterwards introduced, and fastened by an adhesive solution. Unlined hose is used by some provincial brigades; and it is contended that the water passing through it keeps it wet, and therefore not liable to be burned by the great heat of the conflagration. On the other hand, the leakage is said to be a very objectionable defect. The internal diameter of the hose is two inches clear at the couplings, but a little larger within. The steam-man is taught to remember the great power he rules; otherwise he may, by neglecting to give the warning whistle, endanger his brother-fireman's life by suddenly sending the water rushing through the hose, or bringing a great strain upon it, when the men controlling it are not prepared. It may appear an easy thing to stand on a ladder or a house-top, and direct the jet on the fire; but it is not so easy to carry and to guide the long, heavy, and to some extent sinuous pipe, full of the heavy water throbbing and gushing through it at such tremendous pressure, especially when your foothold is none too secure. A fireman lost his life one night, when holding the hose on the parapet of a roof in the Greenwich Road. He overbalanced himself, and fell crashing, head downward, sixty feet or more below, and met a terrible death. Whether this fearful accident was entirely due to the heavy hose, we cannot say; but unless hose be laid straight, it is apt to struggle like a living thing. The reason is obvious. The water rushes through it at great pressure; and if the hose be not quite straight, the pressure on the bent part of the hose is so great that it struggles to straighten itself. Consequently, a fireman turning a stream will probably have to use a great deal of strength.
