Closely conjoined with forethought for utility in the planning of a house is forethought for beauty. It is well to have an artistic imagination in visualizing, as it were, the "hominess" of the house as it will appear after its rawness has been mellowed by time, and its forms have been endeared by association. This imagination is specially essential in the planting of trees, arrangement of flower gardens, the choice of the kind of enclosure, whether hedge or fence, and, in general, all that is known under the name of landscape gardening. The housekeeper's work is greatly dependent upon the kind of water supply available for the house. In cities and towns the kind of supply is fixed for her, but in the country she is afforded her freedom of choice. She has a choice of water from wells or springs, which is more or less "hard," that is, impregnated with lime, and water collected from rain or melting snow. For household purposes rainwater is the more desirable, and, when properly filtered and kept in clean cisterns protected from the larvae of mosquitoes and other disease-bearing insects, it is also the best for drinking purposes. To one accustomed to drinking hard water from a well or spring, rain water is a little unpalatable, but after he is accustomed to its use he will prefer it. It is always wise to secure an analysis of the drinking water of the house, since water reputed pure because of its clearness and coldness is as apt as any other to be contaminated. Where soft water is not available for household use, hard water may be softened by the addition to it of pearline or soda, or by boiling, in the latter case the lime in it being precipitated to the bottom of the kettle or boiler. When well water is used for drinking some knowledge of the geology of the home grounds is essential. Thus, because the top of a well is on higher ground than the cess-pool is no reason for assuming that the contents of the latter may not seep into the water, for the inclination of the strata of the rocks may be in a contrary direction to that of the surface of the ground. When filters and strainers are used they should be carefully cleaned at regular intervals, since if they are permitted to accumulate impurities they become a source of contamination instead of its remedy. Every once in a while the housekeeper should take off the strainers from the faucets and boil them.
