She quickly become lost in a tangle of narrow streets, in the great knot of filthy lanes, and filthier alleys, and atrocious little byways that was the city. The further she went the knot clenched tighter and tighter, until she began to think that the city was going to strangle itself in one enormous noose, began to wonder, too, if there was any way out. On either side, tenements had been built one upon the other, piled higher and higher, and at increasingly crazy angles, until the little shacks at the top were so tipsy it seemed impossible they kept their balance and did not tumble off. Cats prowled on the intermediate roofs, or perched on the overhangs, some of them, indeed, had climbed so high one might easily imagine them a winged species of feline-avian hybrid, as living gargoyles. The upper stories must be wretched little garrets, yet she thought it might be rather fine to live there and look out from a window on a clear night, up among the stars. It would be better, anyway, than dwelling down close to the dingy street, whose odors of dung, garbage, and offal must rise three or four floors a least during the summer.
