Supposing the ground to present the usual surface of boulders and gravel, this must first be smoothed to the proper angle, and excavated toa suitable depth to admit t-he superstructure. Upon the ground thus smoothed and sloped, the-foundation may be laid of fragments of stone and gravel to the depth of 18 inches: and it sliould be exposed for a winter to the effects of frost, in order that it may settle. Upom this foundation are to be laid at intervals of 8 feet, from centre to centre, blocks of stone to support the rail way; these should. be at least 18 inches in thickness, and weigh'not less than 2 cwt. each; the plane of their upper surfaces may be brought nearly. to-the proper slope by wedges of stone, and. must then be finished and opened to admit the rails by the chisel.
