Fig-ure 3 represents one of the homemade land graders. Each runner ismade from a 2 by 6 inch joist, 16 feet long, and is bolted to anotherjoist of the same size, but placed 2 inches higher, as shown in Sec-tion on ABV in the figure. The draft attachment, bracing, and cross-bars, shod with steel, are also fully shown in the drawings. To finish off a field prior to seeding and give it a smooth, uniform,grade the leveler shown in figure 4 is preferred. The framework con-sists of five 4 by 4 inch timbers, having their centers raised by wheels13 inches above the ground. The machine is 12 feet wide and 7 feetlong, and has an adjustable steel-shod share 11 feet 2 inches long and9 inches deep. This implement, when operated by a competent manwith three or four horses, will level from 10 to 20 acres in a day,providing the ground is tolerably even. Details are shown by Per acre. $ LEVELING. 25 When the surface is properly graded grain may be sown with a threeor four horse seeder. In this work care is taken to have the drills runin a direction to facilitate the distribution of water between the fieldditches, since the water readily follows the drill marks. In the Gallatin Valley a cereal crop grows until the plants areabout 6 inches high before preparations are made to irrigate average seasons the seed is usually in the ground by the 10th ofMay and the rainfall during May and June in that locality is seldomless than 5 inches andis often as high as 7inches. This is suffi-cient to maintain thevigor of the plant un-til it attains the heightnamed. Cereals areirrigated for the firsttime early in dry seasons thecrops begin to sufferin June, when watermust be applied, al-though the plantsmay be only 3 incheshigh.
