This is the most probable solution of the general housing problem. Ordinary and wireless telephony, soon to be supplemented by “television,” will gradually reduce the isolation brought about by mere space, while underground and overground transport of goods will render the distribution of supplies less and less laborious. Houses will, therefore, be built more widely apart than they are in cities, and each will have its own private grounds. The structures will be of a material impervious to heat and cold, but transparent or translucent to light, though there will be means of darkening the whole house if desired. Artificial lighting will not be by lamps, but by a close imitation of diffused daylight, which is coolest and most restful to the eyes. There will be no domestic servants. All the “work” of the house will be done by machinery requiring but the turning of a switch and the aiming of implements resembling magic wands. Cooking will be a pleasant domestic art, most of the preparations being made by the purveyors of food stuffs. As it is unlikely that the anatomical structure and the physiological functioning of the human frame will be materially changed for thousands of years to come, food will not be very different from what it is now, but there will be a nicer discrimination of what foods, and what quantity of them, are best calculated to maintain perfect health. _Children._――Most prophets concerning the future of the human race postulate many and radical changes in the birth and rearing of children. Some say that advancing civilization will make the present process impossible on account of the steadily increasing size of the human skull, which will eventually make normal birth impossible. Professor Haldane forecasts “ectogenesis” or the artificial ripening of the embryo outside the human body. Whatever may happen to the physical act of birth――it will no doubt be alleviated in many ways――one hopes that the tender joys of watching over the development of a child’s body and mind will not be taken away from us. Much more enlightened care will, no doubt, be bestowed upon the welfare of the infant than is done at present. How many crimes are unwittingly committed against a child’s mentality by ignorant parents and nurses! Lies and prevarications and evasions are always reprehensible, but with children they are of fatal and life-long effect. We owe the truth to a child more than to any adult. Our promises to a child should be as binding as an oath. Tell them fairy tales by all means, but tell them with a voice and expression which inevitably stamps them as such, and makes belief optional.
