HI. SEED CURING AND STORING. The importance of this is not generally appreciated in the North. In New England and northern New York to North Dakota not. only do killing frosts come early in September in some years, but a freeze heavy enough to destroy the vitality of poorly dried seed is almost sure to come early in October. Seed corn at harvest time con- tains from 20 to 50 per cent water, and in case of freezing this water expands and destroys germination cells. The same water might, under other conditions, favor the heating or molding of the seed. For these and other reasons early selection and.

In storing remember (a) to keep seeds safe from mice and insects; (b) to keep dry, lest moisture absorbed cause premature sprouting or molding; and (c) to keep from excessive cold, as the moisture is never entirely dried out the first season. Have drying and storing contrivances shown and their use demonstrated at school. Refer to Farmers' Buls. 229, 253, 313, 537, and 617. IV. SEED TESTING. In nearly all texts, manuals, and bulletins dealing with seeds the methods of testing seeds are explained and illustrated. This should come in late winter or early spring. Make it clear to pupils that two ears of corn may look equally good, and w
