To begin with, the population of Japan (approximately 60,000,000) is increasing at the rate of about 800,000 per year. China has no modern vital statistics, but the annual increase of her 400,000,000 population, at the Japanese rate, would be 6,000,000. Now the settled parts of both Japan and China may be considered as fully populated so far as agriculture is concerned, further extensive increases of population being dependent upon the rise of machine industry. Both countries have, however, thinly settled areas within their present political frontiers. Japan's northern island of Hokkaido (Yezo) has a great amount of good agricultural land as yet almost unoccupied, some of her other island possessions offer minor outlets, while Korea and Manchuria afford extensive colonizing possibilities albeit Chinese and Korean competition preclude a Japanese colonization on the scale which the size and natural wealth of these regions would at first sight seem to indicate. China has even more extensive colonizable areas. Both Mongolia and Chinese Turkestan, though largely desert, contain within their vast areas enough fertile land to support many millions of Chinese peasants as soon as modern roads and railways are built. The Chinese colonization of Manchuria is also proceeding apace, and will continue despite anything Japan may do to keep it down. Lastly, the cold but enormous plateau of Tibet offers considerable possibilities. Allowing for all this, however, it cannot be said that either China or Japan possess within their present political frontiers territories likely to absorb those prodigious accretions of population which seem destined to occur within the next couple of generations. From the resultant congestion two avenues of escape will naturally present themselves: settlement of other portions of the Far East to-day under white political control, but inhabited by colored populations; and pressure into accessible areas not merely under white political control, but also containing white populations. It is obvious that these are two radically distinct issues, for while a white nation might not unalterably oppose Mongolian immigration into its colored dependencies, it would almost certainly fight to the limit rather than witness the racial swamping of lands settled by its own flesh and blood.
