When civilization is forced upon a lower race, establishing a higher government than they themselves can manage, there is more food production and a very rapid rise of the saturation point. In the semi-savage or barbarous condition existing when the Spaniards came to the Philippines, it is said there were less than a million people. In three centuries there were six million, and in each case it is certain that it is the maximum which could be fed. Spanish engineers have constructed immense irrigation works and have otherwise improved the land so that they raised food for six men where formerly only one could exist.
Egypt has repeatedly had increased density of population when higher races raised the civilization. The population was 7,000,000 when the British assumed control, but it increased to 9,750,000 in 1899, and it is to be further increased by the new storage reservoir made by the Assouan dam, which adds an arable area equal to Rhode Island. The strip on each side of the Nile is equal in area to Vermont and Rhode Island combined - about 1,600,000 acres. In ancient times similar irrigation lakes were constructed by conquering types and the population was consequently much increased, but as the conquerors disappeared, the works were neglected, food diminished and population decreased. Should the British be so foolish as to relinquish control, their present works will be neglected, food will diminish and the population decrease by millions.
Java has had a tremendous increase of population due to a high civilization forced upon the native. The Dutch and the leading natives in Java are even of the opinion that the population is increasing too rapidly. The Island is only a little larger than New York State, and the central regions are too mountainous for a dense population. In 1825 it contained but 5,000,000 people, but the last census showed a total population of 28,-745,698, indicating a frightful congestion of humanity in the plains and valleys. The density is 568 persons for every square mile of surface, which is greater than in any province of China, excepting Shantung. If France had the same density its inhabitants would number 120,000,000; the United States, at the same rate, would have 1,688,000,000, or about the estimated population of the world. Such packing of humanity as this, at least illustrates the fact that when every acre of tillable land is stimulated to its highest productivity, it will give sustenance to several times the number of persons who are now supplied with food. The Javanese are still able to raise all their food and also to export the products of their plantations and forests to the amount of millions of dollars a year. But they are already talking about a time to come when they will no longer be able to produce all the food they require.
One of the curious instances of reversing cause and effect is a report that Prof. Bernard Moses, of the University of California, commenting on the above increase of population and the remarkable extent to which cultivation of every inch of land is carried, said that it was all necessary to keep the rapidly increasing population supplied with food. The real condition is the opposite - the population increases because the food has been increased in quantity. Though a student and professor of social phenomena, he only voices the general ignorance of this first law of nature - all animals exist to the limit of their food supply. If food is not ready for an increase, the surplus must starve.
Long before 500 B. C. Ceylon was overrun from the North by an Aryan-speaking race having a high civilization, with a written language called Pali - a dialect of Sanskrit. It built up a civilization with tremendous irrigating works with artificial lakes of masonry, the remains of which are marvelous. They supported a population of 10,000,000, the ruins of one city alone being sixteen miles in diameter. But the ruling race died out, the civilization died in the hands of the native Cingalese, and non-production of food caused loss of population. Even with English law and order and civilization only about 4,000,000 can find food, and they are frightfully overcrowded; but in ancient times it was a granary for South Eastern Asia.
Venezuela is also an instance in point. Its high civilization was thrust upon it by a higher race, but its population is receding because the people are unable to carry the civilization on. Hence, it is producing less food and less of other things which they could sell to pay for imported food. In 1903 the population was many thousands less than in 1883, and this will continue until Aryans take charge and save the natives from the death they are bringing upon themselves.
The decadence of the Mediterranean civilization in the first five centuries of the Christian era was due to the death of the high types of Northern men who had built it up. Therefore, the high density of population of Csesar's time could not be sustained. There was a very marked reduction of population around the Mediterranean in the various wars which followed the profound peace of the Roman Empire. "It is affirmed that in the African campaign (533 A. D.) 5,000,000 of the people of that country were consumed; that during the twenty years of the Gothic war Italy lost 15,000,000; and that the wars, famines, and pestilences of the reign of Justinian diminished the human species by the almost incredible number of 100,000,000."*
Making due allowance for the exaggerations which were accepted as fact when Draper wrote, we can presume that there was at least a great reduction. Similarly, the dense populations once living in the valleys of the Euphrates and Tigris, were due to the invasion of races more intelligent than the native. They constructed artificial lakes with irrigating canals 400 miles long and 200 to 400 feet wide, and produced enormous quantities of food, where now practically none is raised, and there are no people as a result of the death of the higher race and its civilization.
