When the rack is to be used, the butts of the corncobs are stuck on the nails, as shown in the illustration.

Collections of farm seeds, weed seeds, and farm seeds containing weed seeds as impurities should be made in the schools and kept for use in studying crops, weeds, and seed adul- terations. To care for such collections prop- erly, a case to hold the seeds is necessary. Figure 26 shows a con- venient case in which small bottles of seeds may be stored. The bottles are straight sided, \ inch in diam- eter and 2\- inches deep; they can be pur- chased at drug stores for about 10 cents a dozen. Those with screw tops are more convenient than those with corks. The material re- quired for making the case is a piece of white pine 2 by 4 by 20 inches. Finish the piece to the dimensions shown in the drawing, If by 3 by 19J inches. Gauge two lines -h inch from both sides on one edge. On these gauge lines lay off centers for holes \\ inches apart, beginning \\ inches from one end. Place the piece, with a strip of scrap board against it on one side, in a vi
