To quickly assess the difficulty of the text, read a short excerpt:
Thus, by a few strokes of the handle, if the wood or metal of the cylmder be sufficiently close to exclude the air, and the piston and valves be well fitted to the sides of the pipe, the compressive power of the atmosphere will be removed from the surface of that part of the fluid which is contained within the cylinder, and the atmospherical pressure on the general surface of the well will force it up the barrel to any height less than 33 or 34 feet. Then, supposing the lower valve to be placed... at a less distance than 2t^ feet from the surface, the ascending water will force it open and get admitted into the cylin- der between c and b . . When the piston descends, the weight of the water upon the lower valve closes it, and the fluid, is forced through the upper by the sinking of the piston ; so that, when the handle is returned, the water, which now rests on the upper lid, is carried to- wards the top of the cylinder, and flows out of the spout E ; and the supply from the well, by the com- pression of the atmosphere upon its surface, forces through the valve c into the cylinder, as the upper piston raises the water by the power of the handle.
