a vast and fertile plain drained by three rivers—the Nonni on the north, the Sungari on the northeast, and the Liaoho on the south. This part of China was once regarded as a desert, but since the completion of the Chinese Eastern Railway it has been found to be the most productive soil in China. It supplies the whole of Japan and a part of China with nitrogenous food in the form of soya bean. This bean, the wonderful properties of which were early discovered by the Chinese, contains the richest nitrogenous substance among vegetables and has been used as a meat substitute for many thousand years. Vegetable milk is extracted from this bean, and from this milk various kinds of preparations are made. The extraction from this bean has been proved by modern chemists to be richer than any kind of meat. The Chinese and the Japanese have used this kind of artificial meat and milk from time immemorial. Recently food administrators in Europe and America have paid great attention to this meat substitute, while the export of soya bean to Europe and America has steadily increased. This ManchuMongolian plain is destined to be the source of the world's supply of soya bean. Besides soya bean, this plain also produces a great quantity of various kinds of grains, and supplies the entire Eastern Siberia with wheat. The Manchurian mountains are exceedingly rich in timber and minerals—gold being especially found in great quantities in many localities.
Railway construction in this region has proved to be a most profitable undertaking. At present there are
