Loss of Water by Seepage.—The great loss of Water by seepage during a long run has led to the cementing of ditches, and to the use of miles of large wooden, concrete and iron pipe by the irrigation companies of Southern California; also, where the slope is rapid, paving ditches with rock has been resorted to. Similar efforts naturally suggest themselves to the user of a small water supply to save his flow from loss. The lining of ditches to prevent seepage is being tested by the California Experiment Station at Berkeley, and publica- tion of results is being made.* Where lumber is cheap the use of a board flume is an available means of saving water, when the soil is coarse and leachy. Irrigation from Flowing Wells.—A considerable area of orchard is irrigated from flowing wells in different parts of the State. Nearly. End view of irrigating wheel. everywhere in the artesian districts there are local well-borers who have kept records of the strata traversed in their work, and can estimate closely the cost of securing water by this method. Lifting Water from Flowing Ditch or Stream.—Where a stream has a rapidity of two miles or more per hour, and a lift to a height of six to sixteen feet will give head enough to distance the water over a considerable area, there is nothing cheaper than the current wheel which is largely used in this State. The engraving gives an end view of such a wheel. Eight pairs of arms, carrying flat buckets like those of a steamboat paddle-wheel, extend from a hub rotating on metal bearings. At either end, or both ends, of each bucket are fixed wooden or tin water boxes which fill themselves on entering the water, and on being brought to the highest point of rotation empty thems
