russed beam, supportedat or near its centre, with the arms extending each way, and one end anchoredor counterweighted, to provide for unequal loading. Each end is made up of asection entirely of steel, extending from the shore nearly half way over thechasm. Each section is supported near its centre by a strong steel tower, fromwhich extend two lever arms, one reaching the rocky bluffs, the other projectingover the river 175 feet beyond the towers. The outer arm having no support,and being subject, like the other, to the weight of trains, a counter advantage isgiven by the shore arm being firmly anchored to the rocks on the shore. Thetowers on either side rise from the waters edge; between them a clear span of495 feet over the river, the longest double-track truss-span in the world. Theends of the cantilevers reaching on each side 395 feet from the abutments, leavea gap of 120 feet filled by an ordinary truss bridge hung from the ends of the NEW YORK CENTRAL & HUDSON RIVER R.

Provision is made for expansion and contraction by an ingeniousarrangement between the ends of the truss bridge and of the cantilevers, allow-ing the ends to move freely as the temperature changes, but at the same timepreserving perfect rigidity against side pressure from the wind. From thetower foundations up the whole bridge is steel, every inch of which was sub-jected to the most rigid tests from the time it left the ore to the time it enteredthe structure. The total length of the bridge is 910 feet. Four hundred and forty-seven miles from New York is Niagara Falls, themost inspiring natural wonder known to man. The Niagara River, extendingfrom Lake Erie to Lake Ontario, a distance of thirtymiles, has a total fall of three hundred and thirty-fourfeet; the greater part of the descent being confined within a distance of seven oreight miles.
