. The complete home landscape. Landscape gardening; Gardens. T/7/yj}ijyjWntirmT7^ a--^^^ </3 p«,v loo* Fig. 12.—A good outlet should be provided for every main drainage line. The tile should follow the low ground, about three feet below the surface, and the end should open into a ditch or sewer two feet above the mean water level to prevent backing up and flooding The narrow ditch is dug with the bottom even so that the tiles can be laid securely. They must be laid or fitted tightly together, end to end, but not cemented or joined in any way. The result desired is that water will filter in through the joints, although soil cannot enter to clog the drain. A fall of approximately six inches in 100 feet will carry off all surplus water, and even less than this will serve the purpose, providing the drain is laid correctly. Laying a drain with only a very slight inclination is a task for a skilled engineer and is best left to such as are capable and experienced in these matters. A line of tile laid at the bottom of the cellar foundation will carry oflf water that might otherwise seep through the walls().Where there is only a small amount of surface water to take care of, a dry well can be easily constructed, sufficiently large to handle the surplus. Figures 13 and 14. Fig. 13.—A simple but effective type of dry well for use in connection with walks, drives and paved areas. The dimensions given are satisfactory where a limited amount of water is to be taken care of.
