Besides the importation of corn, there is another resource which can be invoked by a nation whose increasing numbers press hard, not against their capital, but against the productive capacity of their land: I mean Emigration, especially in the form of Colonization. Of this remedy the efficacy as far as it goes is real, since it consists in seeking elsewhere those unoccupied tracts of fertile land which, if they existed at home, would enable the demand of an increasing [pg 152] population to be met without any falling off in the productiveness of labor. Accordingly, when the region to be colonized is near at hand, and the habits and tastes of the people sufficiently migratory, this remedy is completely effectual. The migration from the older parts of the American Confederation to the new Territories, which is to all intents and purposes colonization, is what enables population to go on unchecked throughout the Union without having yet diminished the return to industry, or increased the difficulty of earning a subsistence.

How strictly true this is may be seen by examining the map given in the last census returns,[142] showing the residence of the natives of the State of New York. The greater or less frequency of natives of New York, residing in other States, is shown by different degrees of shading on the map. A large district westward as far as the Mississippi shows a density of natives of New York of from two to six to a square mile, and a lesser density from Minnesota to Indian Territory, on the other side of the Mississippi. The same is shown of other older States. The explanation of the movement can not be anything else than the same as that for the larger movement from Europe to America.

There is no probability that even under the most enlightened arrangements (in older countries) a permanent stream of emigration could be kept up, sufficient to take off, as in America, all that portion of the annual increase (when proceeding at its greatest rapidity) which, being in excess of the progress made during the same short period in the arts of life, tends to render living more difficult for every averagely situated individual in the community. And, unless this can be done, emigration can not, even in an economical point of view, dispense with the necessity of checks to population.

The influence of immigration to the United States from European countries, in lessening the tension in the relation between food and numbers, is one of the most marked events in this century. The United States has received about one fourth of its total population in 1880 from abroad since the foundation of the republic, as will be seen by this table:

Of this number, 5,333,991 came from the British Isles, of which 3,367,624 were Irish.

There came 3,860,624 Germans, 593,021 Scandinavians, and 334,064 French. (See United States “Statistical Abstract,” 1878, 1880, 1883.)

The causes operating on this movement of men—a movement unequaled in history—are undoubtedly economic. Like the migration of the early Teutonic races from the Baltic to Southern Europe, it is due to the pressure of numbers on subsistence.

A still more interesting study is that of the causes which attempt to explain the direction of this stream after it has reached our shores. It is a definite fact that the old slave States have hitherto received practically none of this vast foreign immigration.[144] The actual distribution of the foreign born in the United States is to be seen in a most interesting way by aid of the colored map, Chart No. VIII, giving the different densities of foreign-born population in different parts of the Union. It seems almost certain that the general belief hitherto in the insecurity of life and property in the old slave States has worked against the material prosperity of that section.
