The details of thisingenious machine have already been published. Onepoint of special importance, and unusual in an undertak-ing of this kind, especially of this magnitude, is that it hasbeen brought through to completion without the loss of asingle life. This is the more remarkable when it isremembered that this method of driving under com-pressed air, when the wet bed of gravel was - I SURREY If was a feat of engineering which had never been accom-plished before, and has attracted general attention andpraise from engineers all over the world, and is now in usein tunnel work in this country. The tunneling has beenmade without affecting any building, nor can its course bedetected an3where along the surface of the route. The tunnels are fifty feet below the street, and pas-sengers pay when passing through a turn-stile, a plansimilar to the elevated roads in this countn,-. They thenenter a commodious room, which rests upon a hydrauliclift, which quickly discharges its load on the platform.
