She pulled him gayly along again, and after they had walked a block down and half a block over they stood before the apartment-house of that name, which was cut on the gas-lamps on either side of the heavily spiked, aesthetic-hinged black door.  The titter of an electric-bell brought a large, fat Buttons, with a stage effect of being dressed to look small, who said he would call the janitor, and they waited in the dimly splendid, copper-colored interior, admiring the whorls and waves into which the wallpaint was combed, till the janitor came in his gold-banded cap, like a Continental porker.  When they said they would like to see Mrs. Grosvenor Green’s apartment, he owned his inability to cope with the affair, and said he must send for the superintendent; he was either in the Herodotus or the Thucydides, and would be there in a minute.  The Buttons brought him—­a Yankee of browbeating presence in plain clothes—­almost before they had time to exchange a frightened whisper in recognition of the fact that there could be no doubt of the steam heat and elevator in this case.  Half stifled in the one, they mounted in the other eight stories, while they tried to keep their self-respect under the gaze of the superintendent, which they felt was classing and assessing them with unfriendly accuracy.  They could not, and they faltered abashed at the threshold of Mrs. Grosvenor Green’s apartment, while the superintendent lit the gas in the gangway that he called a private hall, and in the drawing-room and the succession of chambers stretching rearward to the kitchen.  Everything had, been done by the architect to save space, and everything, to waste it by Mrs. Grosvenor Green.  She had conformed to a law for the necessity of turning round in each room, and had folding-beds in the chambers, but there her subordination had ended, and wherever you might have turned round she had put a gimcrack so that you would knock it over if you did turn.  The place was rather pretty and even imposing at first glance, and it took several joint ballots for March and his wife to make sure that with the kitchen there were only six rooms.  At every door hung a portiere from large rings on a brass rod; every shelf and dressing-case and mantel was littered with gimcracks, and the corners of the tiny rooms were curtained off, and behind these portieres swarmed more gimcracks.  The front of the upright piano had what March called a short-skirted portiere on it, and the top was covered with vases, with dragon candlesticks and with Jap fans, which also expanded themselves bat wise on the walls between the etchings and the water colors.  The floors were covered with filling, and then rugs and then skins; the easy-chairs all had tidies, Armenian and Turkish and Persian; the lounges and sofas had embroidered cushions hidden under tidies.
