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. 
Xote 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 
are given. 
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, J 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? inches. Gauge two lines f 6 inch from both sides 
on one edge. On these gauge lines lay off centers for holes 1£ 
inches apart, beginning 1 \ inches from one end. Place the piece, 
with a strip of sera}) board against it on one side, in a vise, and with 
a |-inch bit and brace bore holes 2| inches deep on the centers that 
have been laid off. The scrap board prevents the lumber from
