The whole of Palestine is essentially arid and semi-arid and dry-farming there has been practiced for centuries. With the application of modern methods it should be more successful than ever before. Dr. Aaronsohn states that the original wild wheat from which the present varieties of wheat have descended has been discovered to be a native of Palestine. China China is also interested in dry-farming. The climate of the drier portions of China is much like that of the Dakotas. Dry-farming there is of high antiquity, though, of course, the methods are not those that have been developed in recent years. Under the influence of the more modern methods dry-farming should spread extensively throughout China and become a great source of profit to the empire. The results of dry-farming in China are among the best. These countries have been mentioned simply because they have been represented at the recent Dry-farming Congresses. Nearly all of the great countries of the world having extensive semiarid areas are directly interested in dry-farming. The map on pages 30 and 31 shows that more than 55 per cent of the world's surface receives an annual rainfall of less than twenty inches. Dry-farming is a world problem and as such is being received by the nations.
