One reason for the low price prevailingis that the old rails for sale are of light section. The new track is laid with grooved rails. 6 in. deep, with a C-in. base; they are in CO-ft. lengths and weigh 8G lbs. This is theJohnson (Section 86-329) rail, made by the .lohnson Company. The ties are old 52-Ib. rails. On single track the lies are 7%ft. long. On double track every third tie and all joint ties are16 ft. long, and the intermediate ties 7 ft. long. The 16-ft. tiesextend under and are fastened to all four track rails; they arebent in the center to conform to the street surface. The old-railties are inverted and the rails fastened to them by means ofclamps; tlie clnmps are l%x2% in., beveled on the under side. TLACING CONCRETE. Between the rails and between the tracks a concrete founda-tion for the pavement is laid not less than 6 in. deep. Outsidethe rails the pavement foundation is also of concrete 6 in. all the concrete work is a layer of stone chips and coarsegravel 4 in. deep, which is designed for sub-surface drainage andconnected with the sewers. The tracks were lined and surfaced and securely blocked withstones and wedges before concreting; care was taken that tnemortar boards did not rest upon the rails until the concrete hadset. Very little difliculty was experienced in keeping tlie align-ment and surface correct until the work of concreting was fin-ished. The plan of the tracks and the sections of the street and ofroadbed to larger scale are shown in the engraving reproducedfrom the engineers drawings.
