For many centuries China's population had been constant. Her territory had been saturated with population; that is to say, her territory, with the primitive method of production, had supported the maximum limit of population. But when she awoke and inaugurated the machine- civilization, her productive power had been enormously increased. Thus, on the same territory, she was able to support a far larger population. At once the birth rate began to rise and the death rate to fall. Before, when population pressed against the means of subsistence, the excess population had been swept away by famine. But now, thanks to the machine- civilization, China's means of subsistence had been enormously extended, and there were no famines; her population followed on the heels of the increase in the means of subsistence.
During this time of transition and development of power, China had entertained no dreams of conquest. The Chinese was not an imperial race. It was industrious, thrifty, and peace-loving. War was looked upon as an unpleasant but necessary task that at times must be performed. And so, while the Western races had squabbled and fought, and world- adventured against one another, China had calmly gone on working at her machines and growing. Now she was spilling over the boundaries of her Empire - that was all, just spilling over into the adjacent territories with all the certainty and terrifying slow momentum of a glacier.
Following upon the alarm raised by Burchaldter's figures, in 1970 France made a long-threatened stand. French Indo-China had been overrun, filled up, by Chinese immigrants. France called a halt. The Chinese wave flowed on. France assembled a force of a hundred thousand on the boundary between her unfortunate colony and China, and China sent down an army of militia-soldiers a million strong. Behind came the wives and sons and daughters and relatives, with their personal household luggage, in a second army. The French force was brushed aside like a fly. The Chinese militia-soldiers, along with their families, over five millions all told, coolly took possession of French Indo-China and settled down to stay for a few thousand years.
Outraged France was in arms. She hurled fleet after fleet against the coast of China, and nearly bankrupted herself by the effort. China had nonavy. She withdrew like a turtle into her shell. For a year the French fleets blockaded the coast and bombarded exposed towns and villages. China did not mind. She did not depend upon the rest of the world for anything. She calmly kept out of range of the French guns and went on working. France wept and wailed, wrung her impotent hands and appealed to the dumfounded nations. Then she landed a punitive expedition to march to Peking. It was two hundred and fifty thousand strong, and it was the flower of France. It landed without opposition and marched into the interior. And that was the last ever seen of it. The line of communication was snapped on the second day. Not a survivor came back to tell what had happened. It had been swallowed up in China's cavernous maw, that was all.
In the five years that followed, China's expansion, in all land directions, went on apace. Siam was made part of the Empire, and, in spite of all that England could do, Burma and the Malay Peninsula were overrun; while all along the long south boundary of Siberia, Russia was pressed severely by China's advancing hordes. The process was simple. First came the Chinese immigration (or, rather, it was already there, having come there slowly and insidiously during the previous years). Next came the clash of arms and the brushing away of all opposition by a monster army of militia-soldiers, followed by their families and household baggage. And finally came their settling down as colonists in the conquered territory. Never was there so strange and effective a method of world conquest.
Napal and Bhutan were overrun, and the whole northern boundary of India pressed against by this fearful tide of life. To the west, Bokhara, and, even to the south and west, Afghanistan, were swallowed up. Persia, Turkestan, and all Central Asia felt the pressure of the flood. It was at this time that Burchaldter revised his figures. He had been mistaken. China's population must be seven hundred millions, eight hundred millions, nobody knew how many millions, but at any rate it would soon be a billion. There were two Chinese for every white-skinned human in the world, Burchaldter announced, and the world trembled. China's increase must have begun immediately, in 1904. It was remembered thatsince that date there had not been a single famine. At 5,000,000 a year increase, her total increase in the intervening seventy years must be 350,000,000. But who was to know? It might be more. Who was to know anything of this strange new menace of the twentieth century - China, old China, rejuvenescent, fruitful, and militant!
The Convention of 1975 was called at Philadelphia. All the Western nations, and some few of the Eastern, were represented. Nothing was accomplished. There was talk of all countries putting bounties on children to increase the birth rate, but it was laughed to scorn by the arithmeticians, who pointed out that China was too far in the lead in that direction. No feasible way of coping with China was suggested. China was appealed to and threatened by the United Powers, and that was all the Convention of Philadelphia came to; and the Convention and the Powers were laughed at by China. Li Tang Fwung, the power behind the Dragon Throne, deigned to reply.
