We write this article in September. Within a few days, and without much heralding, has occurred an event of prime importance to our country's future. This is the opening from New York to St. Louis of a continuous broad-gauge line under the title of the Atlantic and Great Western Railway. This line is twelve hundred miles long, and pursues the following route: By the New York and Erie Road, from New York to the station of Salamanca; thence, by a separate road of the Atlantic and Great Western, to Dayton, Ohio; thence, over the Cincinnati, Hamilton, and Dayton Road, to Cincinnati; and finally, by the Ohio and Mississippi Road, to St. Louis. The first excursion-train accomplished the whole distance in forty-four hours. We understand that the regular express-trains of the line will be required to make equally good time,--ultimately, perhaps, to reduce the time to forty hours. This valuable connection has been mainly effected by the energy and talents of two men. Mr. James McHenry, a Pennsylvanian by birth, but of late years resident abroad, has raised twenty million dollars for the project in the money-markets of England, Spain, and Germany, the bonds of the Company obtaining ready sale upon the guaranty of his personal high character for uprightness and financial ability. Mr. Thomas W. Kennard, an engineer and capitalist of large views, discretion, and experience, has managed the interests of the project here at home, securing the hearty cooperation and good-will of all the roads now made continuous, and bringing the enterprise to a successful issue with a skill possible only to first-class commercial genius. The former of these gentlemen is Financial Director and Contractor, the latter, Engineer-in-Chief, Vice-President, and General Manager of the line. At any other period than this their success would have been widely talked of as a great national benefit. Even now let us not forget the public-spirited men whose hopeful hands, in the midst of blood and din, have been sowing seeds of commercial prosperity to glorify with their perfected harvest the day of our National triumph and reunion.
