The piston-rod is attached to one end of a lever, whilst the pump-rod works in connexion with the other,—the hydraulic action employed to raise the water being exactly similar to that of a common sucking-pump. The working of a Newcomen engine was a clumsy and apparently a very painful process, accompanied by an extraordinary amount of wheezing, sighing, creaking, and bumping.
I never expected to see that Jerusalem in which Harry the Fourth died, but there I found myself in the large panelled chamber, with all its associations. The older memories came up but vaguely; an American finds it as hard to call back anything over two or three centuries old as a sucking-pump to draw up water from a depth of over thirty-three feet and a fraction.

It was the failure in the attempt to make a sucking-pump act, when the working bucket was more than thirty-three feet above the surface of the water to be raised, that led observant men to study the law of atmospheric pressure, and opened a new field of research to the genius of Galileo, Torrecelli, and Boyle.
