One phase of those days must by no means go unrecorded -- namely, the Broadway omnibuses, with their drivers. The vehicles still (I write this paragraph in 1881) give a portion of the character of Broadway -- the Fifth avenue, Madison avenue, and Twenty-third street lines yet running. But the flush days of the old Broadway stages, characteristic and copious, are over. The Yellow-birds, the Red-birds, the original Broadway, the Fourth avenue, the Knickerbocker, and a dozen others of twenty or thirty years ago, are all gone.
