(Figs. l to 8) of 126 ft. 6 in. The approach spans are
carried upon cast-iron screw pile piers (Fig. 15 ), and
the main spans upon wrought-iron cylinder piers,
filled with concrete (Fig. 16 ), the total height of
the former varying from 28 ft. to 34 ft., and the
latter from 59 ft . 4 in. to 49ft. 4 in. The main girders

The line of railway is somewhat prolific in long bridges, as, in addition to the one now under notice, there is a five-span bridge at 606.235 kilometres, on masonry piers, an eighteen-span one at 484.920 kilometres, on screw pile piers, and a thirty-five span one over the Sali River, on masonry piers; these are all 65 ft. 3 in. span, and the total weight of ironwork in these three bridges is 1250 tons ; they were all manufactured by the Patent Shaft Company, of Wednesbury. There is also the bridge over the Dulce River, ninety spans of 66 ft. 3 in., on cast-iron screw pile piers, of a total weight of 2500 tons, manufactured by Messrs. Cochrane and Co. , of Dudley. The last four referred to were all "deck" bridges, and, including the subject of our notice, were constructed from the designs and specifications and manufactured under the personal supervision of Mr. Jonathan Packman, M. Inst. C.E ., 63, New Broad-street, London.’
