To quickly assess the difficulty of the text, read a short excerpt:
The water directly absorbs part of the heat, and the cylinder walls are kept cool and moist. In the early compressors of this type very good results as regards efficiency were obtained. But the Mont Cenis compressors were worked at a slow piston speed, and were N 178 DISTRIBUTION OF POWER cumbrous and expensive for the amount of work done. It may be stated, however, that Mr. Leavitt still uses water piston oompressors at the Calumet mines, and by giving suitable form to the pistons and passages... he succeeds in running them at a good speed, and obtains a very satisfactory efficiency. M. Hanarte also, in France, has constructed water piston compressors, with paraboloidal chambers in which the energy of the water pistons is quietly diminished, and shock and loss of energy are avoided. At the St. Gothard Tunnel works compressors of a less effective type were adopted. The compressor cylinder was dry, but was surrounded by a water-jacket. Air does not part with heat readily to a metal surface, and the heat produced was very imperfectly abstracted.
