The various departments of science are so closely interlinked that achievements in each throw light upon the problems of the others, often in vary unexpected ways. It is for those who, taking the worlds as they are, are concerned to make them as better as they can; for those who can see, without elaborate explanation, that sanitary savagery does not well accord with clean living which is a distinguishing mark of civilization; for those who are not too indolent or engaged to look fairly at the reasons which have given rise to the general demand, so frequent today, for clean surroundings, and the physical and mental vigor which these conditions foster.
Clean water is one of the hallmarks of civilization. Today, like never before, we can utilize science and technology to turn the brackish canal waters of Mars, the steamy swamp waters of Venus, as well as less-desirable quantities of water here on Earth, into potable water. Further, once purified, that water can be turned to ice for all manner of purposes, from the preservation of food to the cooling of dwellings. Truly we live in a gilded age.—editor
