Lastly, even the longitudinal roadway gird-ers, of flat bars f in- thick, 4 in. broad and 15 ft. long (on whichthe wooden cross beams carrying the roadway rest), and whichwere carried in the stirrup loops of the suspending rods, were. SUSPENSION liKIUGE OVER THE ULOil RIVER NEAR SAUGOR, INDIA. wholly from native Indian material and by native labor, fromthe designs and under the direction of Major Duncan PresgraveIt carries a highway having a large traffic, and crosses the BeosiRiver near Saugor. The foundations of the bridge, which was designed with onespan of 200 ft. between centers of suspension, were laid inApril, 1828, and the bridge was opened for traffic in June,1830. The abutments were built of stone quarried in the neighbor-hood, set in mortar also made of locally burned lime, and roseup from the rocky bed of the Beosi River wilh a batter of i in5 to a height of 42 ft. over the rock, showing a clear height of36 ft. over low water surface, the batter giving an impressionof massive strength in keeping with the surroundings of thebridge. The abutments were continued on into wing wallswhich ran into the banks on either side a distance of 26 ft., ris- foiged on the spot
