Steam from 22 THE STEAM-ENGINE AS A SIMPLE MACHINE. the boiler being admitted to each vessel, A and A, alter-nately, and there condensing, the Tacuum formed per-mits the pressure of the atmosphere to force the waterfrom the well through the pipes, G and G. While one isfilling, the steam is forcing the charge of water from theother up the discharge-pipe, M As soon as each is emptied,the steam is shut off from it and turned into the other, andthe condensation of the steam remaining in the vessel per-mits it to till again. As will be seen presently, this is sub-.
