Note 1 — THE BUILDING OF A RAILWAY.

It is proper here to say that English engineers now appreciate the merits of the American swivelling truck or bogie. In the article on Railways in the last edition of the "Encyclopædia Britannica," speaking of locomotives, the author of the article, who is an English engineer of high authority, says: "American practice, many years since, arrived at two leading types of locomotive for passenger, and for goods traffic. The passenger locomotive has eight wheels, of which four in front are framed in a bogie, and the four wheels behind are coupled drivers. This is the type to which English practice has been approximating." The italics are ours.
