'The association with whose watch-room I have already made you acquainted. Only we do not need to ring in order to get our regular requirements attended to. The household work is done on the basis of a common tariff without any trouble on our part, and with a punctuality that leaves nothing to be desired. The association possesses duplicates of the house-keys and room-keys of all the houses that it serves. Early in the morning, when we are most of us still asleep, its messengers come noiselessly, take the clothing that has to be cleaned--or rather that has to be exchanged, for we Freelanders never wear the same garment on two successive days--from where they were left the previous evening, put the clean clothes in the proper place, get ready the baths--for in most Freeland houses every member of the family has a separate bath which is daily used, unless a bath in the lake or the river is preferred--clean the outer spaces and some of the rooms, take away the carpets, and disappear before most of us have had any knowledge of their presence. And all this is done in a few minutes. It is almost all done by machinery. Do you see that little apparatus yonder in the corridor? That is a hydraulic machine brought into action by the turning of that tap there, which places it in connection with the high-pressure service from the Kenia cascades. (In other towns, where a hydraulic pressure of thirty-five atmospheres is not so easily to be had, electric or atmospheric motors are employed.) Here the steel shaft in the hollow in the floor covered with that elegant grating, and there near the ceiling the bronze shaft that might be mistaken for a rod on which to hang mirrors or pictures--these transmit the motion of the hydraulic machine to every room in the house, from the cellar to the rooms under the roof. And there, in that room, are a number of machines whose uses I can scarcely explain to you unless you see them at work. The three or four messengers of the association bring a number of other implements with them, and when these machines are brought into connection with the shafts above or below, and the tap of the water-motor is opened, the room is swept and washed while you can turn round, and the heaviest articles set in their places; in short, everything is put right silently and with magical rapidity, though human hands could have done it only slowly and with a great deal of disagreeable noise.
