Between brick walls we thread our way, and begin descending into the abysmal darkness; the tapers, without which it were impossible to proceed with safety, burn feebly in the double night of the subterranean tenements. Most of the habitable quarters under the ground are like so many pigeon-houses indiscriminately heaped together. If there were only sunshine enough to drink up the slime that glosses every plank, and fresh air enough to sweeten the mildewed kennels, this highly eccentric style of architecture might charm for a time, by reason of its novelty; there is, moreover, a suspicion of the picturesque lurking about the place--but, heaven save us, how it smells! [Illustration: "Rag Alley" in Old Chinatown] We pass from one black hole to another. In the first there is a kind of bin for ashes and coals, and there are pots and grills lying about--it is the kitchen. A heap of fire kindling wood in one corner, a bench or stool as black as soot can paint it, a few bowls, a few bits of rags, a few fragments of food, and a coolie squatting over a struggling fire,--coolie who rises out of the dim smoke like the evil _genii_ in the Arabian tale. There is no chimney, there is no window, there is no drainage. We are in a cubic sink, where we can scarcely stand erect. From the small door pours a dense volume of smoke, some of it stale smoke, which our entry has forced out of the corners; the kitchen will only hold so much smoke, and we have made havoc among the cubic inches. Underfoot, the thin planks sag into standing pools, and there is a glimmer of poisonous blue just along the base of the blackened walls; thousands feed daily in troughs like these! The next apartment, smaller yet, and blacker and bluer, and more slippery and slimy, is an uncovered cesspool, from which a sickening stench exales continually. All about it are chambers--very small ones,--state-rooms let me call them, opening upon narrow galleries that run in various directions, sometimes bridging one another in a marvelous and exceedingly ingenious economy of space. The majority of these state-rooms are just long enough to lie down in, and just broad enough to allow a narrow door to swing inward between two single beds, with two sleepers in each bed. The doors are closed and bolted; there is often no window, and always no ventilation. Our "special," by the authority vested in him, tries one door and demands admittance. There is no response from within. A group of coolies, who live in the vicinity and have followed close upon our heels even since our descent into the under world, assure us in soothing tones that the place is vacant. We are suspicious and persist in our investigation; still no response. The door is then forced by the "special," and behold four of the "seven sleepers" packed into this air-tight compartment, and insensible even to the hearty greeting we offer them!
