From their perch up among the rafters Mrs. Gallagher's blind boarders might hear, did they listen, the tramp of the policeman always on duty in Gotham Court, half a stone's throw away. His beat, though it takes in but a small portion of a single block, is quite as lively as most larger patrol rounds. A double row of five-story tenements, back to back under a common roof, extending back from the street two hundred and thirty-four feet, with barred openings in the dividing wall, so that the tenants may see but cannot get at each other from the stairs, makes the "court." Alleys--one wider by a couple of feet than the other, whence the distinction Single and Double Alley--skirt the barracks on either side. Such, briefly, is the tenement that has challenged public attention more than any other in the whole city and tested the power of sanitary law and rule for forty years. The name of the pile is not down in the City Directory, but in the public records it holds an unenviable place. It was here the mortality rose during the last great cholera epidemic to the unprecedented rate of 195 in 1,000 inhabitants. In its worst days a full thousand could not be packed into the court, though the number did probably not fall far short of it. Even now, under the management of men of conscience, and an agent, a King's Daughter, whose practical energy, kindliness and good sense have done much to redeem its foul reputation, the swarms it shelters would make more than one fair-sized country village. The mixed character of the population, by this time about equally divided between the Celtic and the Italian stock, accounts for the iron bars and the policeman. It was an eminently Irish suggestion that the latter was to be credited to the presence of two German families in the court, who "made trouble all the time." A Chinaman whom I questioned as he hurried past the iron gate of the alley, put the matter in a different light. "Lem Ilish velly bad," he said. Gotham Court has been the entering wedge for the Italian element, who until recently had not attained a foothold in the Fourth Ward, but are now trailing across Chatham Street from their stronghold in "the Bend" in ever increasing numbers, seeking, according to their wont, the lowest level.
