Burgin " 202 " " G. Swannanoa " 1,800 " " [Footnote 1: For the sake of economy of space, our cut omits the Point and Swannanoa tunnels (the latter is the summit tunnel), but covers all of the location which is of interest to engineers, the remainder at the Swannanoa end being almost "on tangent" to and through the summit.] The work was done by the State of North Carolina with convict labor, under the direction of Mr. Jas. A. Wilson, as president and chief engineer, but was sold by the State to the Richmond & Danville system.--_Railroad Gazette_. * * * * * NEW GASHOLDER AT ERDBERG. |
