After a satisfactory trial it was decided to apjjly the ideato some heavy Mikado type locomotives built by the Amer-ican Locomotive Company in 1916, and to ten Pacific tyjjepassenger locomotives Ijuilt by the same iom[)any in tiic early part of 1917. The main rod back end on these loco-nictives is an integral part of the rod, no bolts being neces-sary, and the arrangement of steel liushing and bronze linerbeing the same as in Fig. 1. The sectional brasses ordinajily applied to main rod backends are very heavy, and with the high cost of brass, to-gether with the cost of machining and fitting the brasses,liners and keys, the job becomes very expensive. The bushing can be turned, bored, and fitted in aboutone-fourth the time required to fit up the sectional amount of brass is materially less, and the float
