incalculable chemical reactions between its several parts. Lime, mortar, and microscopical organisms are producing undesigned chromatic effects in the paper and plaster; the plaster, having methods of expansion and contraction of its own, crinkles and cracks; the skirting, having absorbed moisture and now drying again, opens its joints; the rough-cast coquettes with the frost and opens chinks and crannies for the humbler creation. I fail to see the necessity of (and, accordingly, I resent bitterly) all these coral-reef methods. Better walls than this, and better and less life-wasting ways of making them, are surely possible. In the wall in question, concrete would have been cheaper and better than bricks if only "the men" had understood it. But I can dream at last of much more revolutionary affairs, of a thing running to and fro along a temporary rail, that will squeeze out wall as one squeezes paint from a tube, and form its surface with a pat or two as it sets. Moreover, I do not see at all why the walls of small dwelling-houses should be so solid as they are. There still hangs about us the monumental traditions of the pyramids. It ought to be possible to build sound, portable, and habitable houses of felted wire-netting and weather-proofed paper upon a light framework. This sort of thing is, no doubt, abominably ugly at present, but that is because architects and designers, being for the most part inordinately cultured and quite uneducated, are unable to cope with its fundamentally novel problems. A few energetic men might at any time set out to alter all this. And with the inevitable revolutions that must come about in domestic fittings, and which I hope to discuss more fully in the next paper, it is open to question whether many ground landlords may not find they have work for the house-breakers rather than wealth unlimited falling into their hands when the building leases their solicitors so ingeniously draw up do at last expire. [27] The new aspects of building, for example, that have been brought about by the entrance of water and gas into the house, and the application of water to sanitation. [28] The future of the servant class and the future of the artist are two interesting questions that will be most conveniently mentioned at a later stage, when we come to discuss the domestic life in greater detail than is possible before we have formed any clear notion of the sort of people who will lead that life.
