Text Appearing Before Image: them. By the common pile a comparatively small mass ofiron fell with great velocity for a considerable height—the 20; OUR IRON ROADS. velocity being in excess and the mass deficient, and calculated,like the momentum of a cannon ball, rather for destructivethan impulsive action. In the case of the steam pile-driver,on the contrary, the whole weight of a bearing mass is deliveredrapidly upon a driving-block of several tons weight placeddirectly over the head of the pile, the weight never ceasing,and the blows being repeated at the rate of a blow a second,until the pile is driven home. It is a curious fact, that therapid strokes of the steam hammer evolved so much heat thaton many occasions the pile head burst into flame. The firstpile was driven to a depth of 32 feet in four minutes ; and assoon as one was placed, the traveller, hovering overhead, pre-sented another, and down it went, like a pin into a pincushion. Text Appearing After Image: THE HIGH-LEVEL BRIDGE AT NEWCASTLE. When the piles had been driven and the cofferdams completedthe water was pumped out. But though powerful engines wereemployed, it forced itself through the bed of quicksand as fastas it was removed. Every effort -was made for months to over-come it, but without success ; until, at last, cement concretewas put in, which set, a foundation was made, and the pierswere securely built. There are two roadways, one level with the Castle-garth,for carriages and foot-passengers, and the other 22 feet above it.The carriage-road is 1,380 feet in length. The bridge is 112^feet from high-water line to the top of the parapet, and theroadway is 80 feet above the water. Six arches, each of 125 ROYAL BORDER BRIDGE. 20 feet span, form the bridge,—the piers upon which they restbeing of masonry, and the arches, pillars, braces, and transversegirders of iron. The bridge-piers are nearly 50 feet by 16 inthickness; and in height are 131 feet from the foundation,having an Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work. -
