Leaving the Elevated Railroad where it dives under the Brooklyn Bridge at Franklin Square, scarce a dozen steps will take us where we wish to go. With its rush and roar echoing yet in our ears, we have turned the corner from prosperity to poverty. We stand upon the domain of the tenement. In the shadow of the great stone abutments the old Knickerbocker houses linger like ghosts of a departed day. Down the winding slope of Cherry Street--proud and fashionable Cherry Hill that was--their broad steps, sloping roofs, and dormer windows are easily made out; all the more easily for the contrast with the ugly barracks that elbow them right and left. These never had other design than to shelter, at as little outlay as possible, the greatest crowds out of which rent could be wrung. They were the bad after-thought of a heedless day. The years have brought to the old houses unhonored age, a querulous second childhood that is out of tune with the time, their tenants, the neighbors, and cries out against them and against you in fretful protest in every step on their rotten floors or squeaky stairs. Good cause have they for their fretting. This one, with its shabby front and poorly patched roof, what glowing firesides, what happy children may it once have owned? Heavy feet, too often with unsteady step, for the pot-house is next door--where is it not next door in these slums?--have worn away the brown-stone steps since; the broken columns at the door have rotted away at the base. Of the handsome cornice barely a trace is left. Dirt and desolation reign in the wide hallway, and danger lurks on the stairs. Rough pine boards fence off the roomy fire-places--where coal is bought by the pail at the rate of twelve dollars a ton these have no place. The arched gateway leads no longer to a shady bower on the banks of the rushing stream, inviting to day-dreams with its gentle repose, but to a dark and nameless alley, shut in by high brick walls, cheerless as the lives of those they shelter. The wolf knocks loudly at the gate in the troubled dreams that come to this alley, echoes of the day's cares. A horde of dirty children play about the dripping hydrant, the only thing in the alley that thinks enough of its chance to make the most of it: it is the best it can do. These are the children of the tenements, the growing generation of the slums; this their home. From the great highway overhead, along which throbs the life-tide of two great cities, one might drop a pebble into half a dozen such alleys.
