The whole arrange-ment was designed with a view of reducing the number ofseparate pieces to the minimum and at the same time to pro-duce a structure that would be sufficiently strong to permit ofcarrying the load entirely upon the center plates. The bol-sters and other steel castings were designed and furnished bythe American Steel Foundry Company of Granite City, Illinois,and these parts are guaranteed to outlive the cars without ex-cepting wrecks.

Thetime has now arrived when mechanics can readily see the ad-vantages to be gained in the minimum number of pieces in anypart of a truck or other machinery, and it is to this end thatI find it most advantageous. What we need is a truck thatwill stand all abuses possible after derailments, so that thetrucks may be replaced on the tracks and continue thei
