Preparing land for irrigation and methods of applying water . the 18 nearest depression. The second leveler takes off more earth and carriesit farther: the third continues the process. Scraper Xo. 4 is controlledby the lever and can be raised and lowered at will. This is of particularadvantage if the knoll has become compact: for as much of the weightof the machine as desired can be applied to this scraper. The fifth andsixth levelers complete the process. The machine has the additionalweight of the driver on the front and the lever tender on the rear. Ifthere is uniformity in the size and position of the knoll-, and this iswhere this leveler has its greatest value, the field is worked over inlong narrow lands, from one-half a mile to a mile long and 100 or 200yards wide. MODIFIED BUCK SCRAPER. This implement is especially useful on -lightly uneven ground, smalldetached hummocks, or small washes. For this class of work it ispreferable by far to any other known to the writer. A similar machinehas been used in the San Joaquin Valley of Fig. 2l—Modified buck scraper (planer). This leveler. called a planer (fig. 2). is composed of a 14-foot horizontalor base timber 4 by V2 inches, and a back of 2-inch lumber IS incheshigh. The timbers are held together by the extension of the steel platewith which the base is shod, and also by i by 1+ inch iron straps fromthe top of the base to a point near the top of the vertical piece. Thebase is beveled toward the front and shod with plate steel to make ittake dirt. Each end of the base exteuds 1 foot beyond the end of thevertical portion to which footboards are bolted. Outside of and belowthe footboards are the iron straps to which the teams are each footboard stands a driver of four mules, and together theygovern the action of the planer. On approaching a small mound thedrivers stand on the forward ends of the footboards, thus depressingthe blade. As the planer moves forward a layer of earth is shaved off
