The encyclopedia of practical horticulture; a reference system of commercial horticulture, covering the practical and scientific phases of horticulture, with special reference to fruits and vegetables;. Gardening; Fruit-culture; Vegetable gardening. XlMraUn*L Illustration No. 1 is for a field where the general slope is in one direction with low point in or near the middle of low side. 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 IWu&TraTion Z ^ ' " ' Lowroint Illustration No. 3 shows a head ditch running on a ridge diagonally through the tract, feeding irrigation rows on either side on different slopes. You will note there are two low points on this tract, requiring that there be two sets of contour ditches. The level, however, is set as in Illustrations Nos. 1 and 2, at the lowest point, and the contour levels ascertained in the same manner. Illustration No, 4 shows two sorts of home-made levels. Either of these will be sufficiently accurate for running these contour lines. Of course, a surveyor's. Please note that these images are extracted from scanned page images that may have b
