But the life of the special work is meas-ured by that of the crossing points, which, in cases of heavytraffic, proved to be much shorter than that of the curved orstraight portions of the track. The problem then resolved itselfinto one of finding some material which would withstand theheavy wear at these points. In this, the managers of The John-son Company decided that they could select no better ma-terial than case-hardened steel, which modern investigation hasshown to be the most durable under wear of any form of ironor steel. Brifly stated, the plan contemplated the insertion atthe crossing point of a plate of hardened steel let into the cast-ing of the frog or mate, and held in place by cast zinc, whichwas poured around the plate.
