The zigzag method of taking the waterdown hills on the dry ridges, distributing to right and left, picking it upagain in zigzag ditches at the end of the rows or system, to be used againon lower ground, brings into use the largest quantity where it is mostneeded and utilizes it all without waste. Irrigating by Small Furrows.—It has already been suggestedthat recently the small furrow method of irrigation is undergoingcertain modifications. The occasion for the change is that in. Newer system of furrow irrigation at Riverside, Cal. 198 CALIFORNIA FllUITS: HOW TO GROW THEM certain of the heavier soils, particularly, the use of water in manyshallow - furrows followed by cultivation results in the formationof a compact layer, and this prevents the percolation of the waterinto the subsoil. This discovery led many Southern growers toresort to fewer and deeper furrows and to new devices to enablethe tree to get the benefit of the water. There has been wideuse of the subsoil plow, with a wedge-shaped foot attached to aslim standard rising to the ordinary beam. The standard opposesits thin edge to the soil so as to cleave it with the least difficulty,and the foot, passing through or beneath the hardpan, lifts andbreaks it. The result of the subsoiling is to open a way for thewater to sink and spread below the hardpan. It is usual to runthis plow once through the center of the interspace between therows of trees, sometimes
