red, it is attacked in wet weather by the oxygen of the air, a portion of its carbon is burned off, some of its starch is converted into sugar, and in extreme cases it germinates and becomes _malty_. But not only is the seed liable to injury from the elements; it is also exposed to the ravages of the feathered tribe, and no matter how well a field of corn may be watched, or how great the number of _scarecrows_ erected in it, there is always a certain diurnal loss, occasioned by the ravages of birds. It is not only necessary that ripe corn should be cut as soon as possible, but it is sometimes desirable to reap it before it becomes fully matured. When the grain is intended for consumption as food, the less bran it contains the better. Now the bran, as is well known, forms the integument, or covering of the vital constituents of the seed; and it is the last part of the organ to be perfected. The growth of the seed for several days before its perfect development, is confined to the _testa_ or covering. Now as this is the least valuable part of the article, its increase is matter of but little moment; and when it is excessive it renders the grain less valuable in the eyes of the miller. That the cutting of the grain before it is perfectly ripe is attended with a good result, is clearly proved by the results of an experiment recorded in Johnston's "Agricultural Chemistry." A crop of wheat was selected; one-third was cut twenty days before it was ripe; another third ten days afterwards; and the remaining portion when its grain had been fully matured. The relative produce in grain of the three portions taken, as stated above, was as 1, 1.325, and 1.260. The following table exhibits the relative proportions of their constituents:-- In 100 parts of the grain cut at 20 days. 10 days. Dead ripe.
