A common rule in stationary practice has been to makethe diameter of the low pressure cylinder 2 inches less thantwice the diameter of the high pressure cylinder. The question of the correctness of these limits has been boldlyand consistently presented by Mr. George I. Rockwood, who ex-pressed his views in our columns in 1891 in an article entitledHow Many Cylinders Will It Pay to Introduce in the Multi-Cylinder Engine? That article was
