. Better fruit. Fruit-culture. Figure 3—CLEARING BRUSH IN IMPERIAL VALLEY, CALIFORNIA rapidly taking the place of farthcn head ditches. These flumes vary in width from eight to t\vel\-e inches, and the openings are cuntrolled metal or wooden gates in the manner shown in Figure i:!. Throughout the southern and central portions of California cement flumes and pipes of \arious kinds are Cjuite generally used t(_) distribute water to furrows. A common type of flume is shown in Figure 14. In the process of building, and before the cement hardens, small metal tubes are inserted on the side next to the orchard, the flow through each tube being regulated hy a gate of the same material. When pipes are used a line is laid across the lop of the tract to be watered at the proper depth below the surface, and at regular distances standpipes are inserted to bring the water to the surface, where it is divided between a number of furrows In- special devices. Where water is pumped from wells, and where it is conducted from gravity canals under pressure, a convenient way of irrigating certain crops is by means of surface pipes. These pipes are made at the factory into convenient lengths, usu- ally ten feet, of various diameters, and of different weights and kinds of metal. When not in use they are stored in an outbuilding or shed and carted to the field which is in need of water. In the main feed pipe, which is laid under- ground acr(}ss the top of the field to be watered, there are standpipes at regular intervals, and a length of the movable pipe is attached to the lowest standpipe, using heavy canvas hose to make the connection. To this length others are attached until a line extends on one side of the field to within a short distance of the b(jttom. When the water is turned on a section of can\as hose serves to distribute the water down the slope and as far on each side as the hose will reach. Se\eral lengths of pipe are then removed and carried over to an adjoining strip. T
