Heavy lines indicate large furrows made with two-horse plow on contour levels These heavy lines represent practically level ditches. Illustration No. 2 is where the slope is in two directions with low point at one corner. Here again heavy lines indicate large furrows made with two-horse plow. To locate these level contour ditches place an instrument at low point, then take stakes numbered 1, 2, 3, etc, and place them on the two boundary lines at elevations six inches, one foot or two feet apart, according to the steepness of the field. Then turn the instrument up the diagonal row and place another line of stakes numbered 1, 2, 3, etc., on the same levels as those on the boundary. By plac- ing these stakes along the fence row or under the trees they can be left through- out the season. In this way the ditches can be cultivated over and remade for the next irrigation without the use of any instrument or running of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lowther, Granville, ed; Worthington, William, 1871-.
