The three great works, however, with which his name will always be most intimately associated, and which are the grandest monuments of his genius, are the High Level Bridge at Newcastle, the Britannia Bridge across the Menai Straits, and the Victoria Bridge across the St. Lawrence at Montreal. The first two are sufficiently well known--the one springing across the valley of the Tyne, between the busy towns of Newcastle and Gateshead; the other spanning, in mid air, a wide arm of the sea, at such a height that vessels of large burden in full sail can pass beneath. The third great effort of Robert Stephenson's prolific brain he did not live to see the completion of. The Victoria Bridge at Montreal is constructed on the same principle as the Britannia Bridge, but on a much larger scale. "The Victoria Bridge," says Mr. Smiles, "with its approaches, is only sixty yards short of two miles in length. In its gigantic strength and majestic proportions, there is no structure to compare with it in ancient or modern times. It consists of not less than twenty-five immense tubular bridges joined into one; the great central span being 332 feet, the others, 242 feet in length. The weight of the wrought iron on the bridge is about 10,000 tons, and the piers are of massive stone, containing some 8000 tons each of solid masonry." After the completion of the Britannia Bridge, and again after the opening of the High Level Bridge, Robert Stephenson was offered the honour of knighthood, which, like his father before him, he respectfully declined. In 1857 he received the title of D.C.L. from the University of Oxford; and for many years before his death he represented Whitby in Parliament. He was passionately fond of yachting, and almost immediately after a trip to Norway in the summer of 1859, he was seized with a mortal illness, and died in the beginning of October. On the 14th October he was buried in Westminster, amongst the illustrious dead of England.
