h per rod, depending upon the nature ofthe soil. No special devices are manufactured and put upon the market forbuilding laterals, and farmers have been obliged to depend upon theirown ingenuity. The following device was constructed to simplify thework of excavating ditches. Two steel-beam plows, one with a rightand the other with a left share, were placed side by side and theirbeams riveted together. The shares of the plows were spread togive the furrows a width of 2 feet on the bottom. The rear ends ofthe shares were rounded instead of being drawn to the usual point.Above the moldboards of the plows and riveted to them were placedthe right and left moldboards of old alfalfa plows. (PI. II, fig. 1.)The handles bolted to the lower moldboards were spread wider than inthe ordinary plow and were braced to the beams. (PI. II, fig. 2.) The beams running side by side were bent apart toward the end, U. S. Dept. of Agr., Bui. 145, Office of Expt. Stations. Irrigation Investigations. Plate II.

Fig. 2.—Homemade Lateral Plow. Rear View. 23 affording an opening wide enough to insert a 1 by 1 inch timber 2 feetlong, which is bolted in place and on which the devices are fastened. This plow is drawn by from four to eight horses, according to thecharacter of the ground and depth of lateral to be made. In oneoperation it turns two furrows to opposite sides of the ditch andthrows them high on the banks, leaving an unusually clean bottom about2 feet in width. Many plows of different sizes similar to this, madeentirely on the farm or with the help of the village blacksmith, maybe seen about Greeley, Colo. Another homemade furrowing device is the so-called A, which isdrawn through an ordinary plow furrow and crowds the loose earthto the sides. No description of this implement is necessary, as it isused quite commonly throughout the West. LAYING OUT LATERALS. In laying out a system of laterals to serve a farm of, for instance,160 acres, it is important for the future saving of money a
