Rails, switches, and flanges which project above the pavementprove very objectionable. They cause unequal wear and ruts in streetsurfaces, the proper repair of which absorbs thousands of dollars ineach city. Generally the repairs are not made. Then the obstruc-tion to traffic and street-cleaning causes great expense to the privateand public purse. Thirty per cent, of the cost of proper repairs topavements on streets having center-bearing, side-bearing, or otherpoor rails, is caused by the presence of these rails. Traffic seeks, or.

Thirty per cent, of the cost of sweeping (not removalor disposal) of the dirt from the streets of New York in 1896 was dueto the poor forms of rails and the ruts they caused. The form of steel rail which is most efficient and economical forall concerned is a firmly-set girder-rail with a flat upper surface con-taining a groove.
