Jardine has reminded the dry-farmers of the United States that before the production of wheat on the dry-farms can reach its full possibilities under any acreage, sufficient quantities must be grown of a few varieties to affect the large markets.  This is especially important in the intermountain country where no uniformity exists, but the warning should be heeded also by the Pacific coast and Great Plains wheat areas.  As soon as the best varieties are found they should displace the miscellaneous collection of wheat varieties now grown.  The individual farmer can be a law unto himself no more in wheat growing than in fruit growing, if he desires to reap the largest reward of his efforts.  Only by uniformity of kind and quality and large production will any one locality impress itself upon the markets and create a demand.  The changes now in progress by the dry-farmers of the United States indicate that this lesson has been taken to heart.  The principle is equally important for all countries where dry-farming is practiced.

Other small grains

Oats is undoubtedly a coming dry-farm crop.  Several varieties have been found which yield well on lands that receive an average annual rainfall of less than fifteen inches.  Others will no doubt be discovered or developed as special attention is given to dry-farm oats.  Oats occurs as spring and winter varieties, but only one winter variety has as yet found place in the list of dry-farm crops.  The leading; spring varieties of oats are the Sixty-Day, Kherson, Burt, and Swedish Select.  The one winter variety, which is grown chiefly in Utah, is the Boswell, a black variety originally brought from England about 1901.

Barley, like the other common grains, occurs in varieties that grow well on dry-farms.  In comparison with wheat very little seareh has been made for dry-farm barleys, and, naturally, the list of tested varieties is very small.  Like wheat and oats, barley occurs in spring and winter varieties, but as in the case of oats only one winter variety has as yet found its way into the approved list of dry-farm crops.  The best dry-farm spring barleys are those belonging to the beardless and hull-less types, though the more common varieties also yield well, especially the six-rowed beardless barley.  The winter variety is the Tennessee Winter, which is already well distributed over the Great Plains district.

Rye is one of the surest dry-farm crops.  It yields good crops of straw and grain, both of which are valuable stock foods.  In fact, the great power of rye to survive and grow luxuriantly under the most trying dry-farm conditions is the chief objection to it.  Once started, it is hard to eradicate.  Properly cultivated and used either as a stock feed or as green manure, it is very valuable.  Rye occurs as both spring and winter varieties.  The winter varieties are usually most satisfactory.
