The pressure of the genei-ated gas forces the mingled gas and waterthrough the f>ipe-system. An example of a chemical-engine of thesecond class is given in Fig. 2, which repie-sents the Jjindgren-Mahan Chemical Fire-Ejigine(Fig. 3), here shown as a light, easily drawnvehicle for town or village use. In this apparatus there is used a fire-extinguishing fluid,which is claimed to liberate an oxygen-destroying gas on coming in contact with the fire,the eilect of 1 gallon of which is equal to that of 800 gallons of water. The principle of.

The receptacle is filled with the solution, and with strongly com-pressed air, by means of which the liquid is projected. In the large engine the receptacle
