Still, the huge tunnel at Blackwall, which was carried out by Mr. Binnie, Chief Engineer of the London County Council, with Mr. Greathead and Sir Benjamin Baker as Consulting Engineers, is probably one of the most daring and stupendous enterprises of the kind ever undertaken. To hollow out a subway hundreds of feet long under the Thames, only seven feet from the bed of the great river, and through loose gravelly soil, was a great triumph. It was achieved not by uncalculating bravery, but by a wise combination of cool courage, superb skill, and admirable foresight. To design effectively, to provide for contingencies, to be daunted by no difficulties—these qualities help to produce the Triumphs of Engineers, as well as do great inventive skill, the power of adapting principles to varying circumstances, and high-spirited enterprise in planning and conducting noble and useful works. These works may well rank among the great achievements of man’s effort and the wonders of the world. THE END. LORIMER AND GILLIES, PRINTERS, EDINBURGH.
