These liners are bored to the cylinder diame-ters—namely, 30 in., 51 in. and 78 in.—after being placed inposition, and have a uniform thickness of 1$ in. for all thecylinders. Care was taken to bore these while the cylinderswere in a vertical position, so as to prevent all springing due tothe weight of the metal, so the boring was done in the workingposition of the cylinders. The linings are so counterborcd at. ENGINE U. S.

The man-hole coversfor the cylinder heads are of cast steel, made of a dish form, soas to clear tire piston-rod nuts, and are secured by -|-in. steelstuds. The cylinders are steam jacketed on the top, sides andbottoms, the space left about the working linings for the steamjackets being not less than 1 in.
