Flooding the surface of land from field ditches or laterals is the most common mea'ns of wetting soil. This method is general in the Rocky Moun- tain States, and the conditions which prevail there seem to be well adapted to this mode of applying water. It can be used on quite steep slopes and in various other ways fits in with the requirements of the irrigator on the more elevated lands. It consists in lev- eling, grading and smoothing the sur- face of fields to such a degree that water will readily flow over it. As a means of distributing the water over the field small ditches or laterals are located along the best routes. These form a network of channels which cut up the field into small strips, which are usually from fifty to one hundred or more feet in width. Custom differs as to the direc- tion of these field ditches. Sometimes they extend down the steepest slope of the field regardless of the fall, at other times they follow grade lines and extend from the head ditch in more or less curved lines across the field, Figure S. In preparing a field for this method it is first plowed and harrowed and then graded. Several good home-made imple- ments are used to reduce the surface to an even, uniform grade. A convenient implement to make field laterals is shown in Figure 7. It consists of a lister plow, either fourteen or sixteen-inch, attached to a sulky frame and drawn by three horses. When th& ditches extend down the steepest slope of the field they are located by eye, but when they are located on grade lines, as in Figure 8, some kind of a surveying instrument is frequently required to establish the grades. A suit- able fall for these small channels is one- half to three-fourths inch to the rod. The check method is illustrated in a general way in Figure 0. It consists in the division of the field into checks, or
