General Albert S. Johnston arrived in this city yesterday afternoon, on the Danville train, having come via Chattanooga, Lynchburg, &c., from New Orleans. He is about six feet high, his face is well sun browned by a Southern sun, he wears a moustache, but no whiskers, is well-built, having no superabundant flesh, has the look as of one trained to command, and presents a soldierly appearance in every respect.
