and 6 feet long. Exact measurements, however, are not necessary. 

 Smooth up the pieces, bore a half-inch hole near one end, and loop 

 a rope through it. This rope is hung over a nail or hook in the 

 ceiling of the storage room when the rack is in use. Drive 10 finish- 

 ing nails on each side of the piece, spacing them 5§ inches apart. 

 Number the nails from 1 to 40 (there will be 10 on each side of the 

 piece). This may be done with a pencil, or figures may be cut from 

 a calendar and the numbers pasted on the wood. When the rack is 

 to be used, the butts of the corncobs are stuck on the nails, as shown 

 in the illustration. 



Note to Teacher.— The pupils should be impressed with the necessity of storing 

 seed corn properly. The making of these racks by the pupils will create an interest 

 in this phase of the work. In Farmers' Bulletins other devices for drying seed corn

° EXERCISE VI. SEED SAMPLE CASE. 



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 19 J 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 vise, and with 

 a f-inch bit and brace bore holes 2* inches deep on the centers that 

 have been laid off. The scrap board prevents the lumber from
