Place sand or soil in the box, and it is ready for use. A seed germinator similar in construction to the one just de- scribed, but without the wires, is often used in seed-corn testing work. Figure 23 shows a perspective drawing of a convenient- sized tester of this kind. The box is 12J inches wide, 18£ inches long, and 2 inches deep. A box of this size will test 45 ears of corn. The box used in the previous exercise can be used if desired. Half fill the box with sand or sawdust that has been soaked in water at least an hour, pack the material level, and above it stretch a piece. Fig. 23.—Seed germinator. of muslin that has been ruled into 2-inch squares. Number the squares from 1 to 45, as shown in the illustration. Place the kernels to be tested, germ side up, in the spaces, cover the cloth with another piece of cloth a few inches larger than the box, and place wet sand or sawdust above this cloth. Cover the box with a piece of glass or oilcloth to prevent evaporation of the moisture and set it away in a warm place for a few days. When examining the kernels to see if they have germinated, always roll the top cloth back care- fully, otherwise you are likely to get the kernels from the different squares out of place. In the illustration the part marked A shows germinated kernels, that marked B the numbered squares, and that marked C the kernels ready to be tested. Instead of filling the box with sand or sawdust, the seed bed can be made of heavy canton flannel or similar ma
