Byplacing the tower in the street opposite the building, one sweep of the 2-in. stream is suffi-cient to break all the glass from the windows, and give the building such ventilation as willenable the firemen to enter and quickly locate, and often extinguish, the fire in its is also very useful in lumber-yard fires, or in frame districts, and will wet an area of 400 diameter at one setting. It requires but two men to operate it. Fire-Harxess.—A form of swinging harness employed to expedite the securing of the horsesto fire-engines is represented in Fig. 4. The harness is usually suspended and so disposedthat when the horse, after being automatically released from his stall, places himself under it,. Fig. 4.—Fire-harness suspended. it may be immediately lowered into position upon the animal and fastened in the quickestpossible manner. In the stall swinging harness the suspending device consists of a hollowbar through which passes a rod. This rod connects with the lever B, Fig. 4, on the rock-shaft, which engages with the top and outside rings of the breeching. The rod is pivotedto the arm D. The rock-shaft has hooks A, which are held in upward position bv the weightof the collar when attached to arm D. By clasping the harness and collar combinationaiound the horses neck, the hook which is permanentlv attached to the harness automati-cally releases the lever I). The rock-shaft then rotates and the hooks A turn downward, thebreeching drops on the horse, and the whole suspending device runs up to the cei
