A farm colony springs up in a region similar to that held by the colonizing state, that is to say, in the temperate zone. Colonies of this class have appeared both north and south of the equator. The requirements are that the conditions of soil and climate be such as to make the products of the colony similar to those of the home state, and to render acclimatization either unnecessary or very easy.

Under these conditions, a large movement of population takes place from the home state to the colony, and it is a movement of families. Men find it possible to take their wives and children with them, and a normal population is established in the new land. Agriculture may be taken up according to the methods with which the colonists are familiar in the old country. As land is abundant and cheap, each man will prefer, and will find it possible, to take up a piece of land of his own, and to cultivate it independently, rather than to hire out his services to any other cultivator. Consequently, hired agricultural labor is almost impossible to secure, and each man is compelled to rely on the labor of himself and his family to cultivate his land. As a result, the typical agricultural unit becomes the small holding, occupied and tilled by a single family. The system is further established by the fact that the products of such a region are well adapted to this form of culture. This is the typical “farm” organization which gives its name to this class of colony.

Plantation colonies, on the other hand, arise in regions different in climate from the home state, that is, in tropical or subtropical regions. Here conditions of soil and climate are such that the natural products are of a kind which cannot be raised under home conditions, and hence are luxuries rather than staples. Acclimatization is practically impossible for men, and almost wholly so for women, so that normal family life is precluded for the colonist. Furthermore, as it is impossible for natives of the temperate zone to engage in agricultural labor in the tropics, for physiological reasons, all work of that kind must be performed by the natives, or by other similar races imported for the purpose. As a rule, the natives do not wish to work, and wages are no sufficient inducement. Hence they must be made to work, and slavery, either openly or in one of its disguised forms, appears. Since a very small number of Europeans will suffice to direct the activities of a large number of natives, the movement of population from the home state is small, and we find agriculture in the tropics developing along the line of a large unit, producing a single commodity, and operated by compulsory labor, under conditions of waste and exploitation. This is the typical “plantation.”

Thus we see that the social and industrial conditions are diametrically opposed in the two forms of colony. In the farm colony we have a vigorous population, similar in stock to that of the home state, each family tilling its own piece of land, and largely self-supporting. Under such conditions large families are an economic advantage, and population grows rapidly. In the plantation colony the colonists are few and mostly males, who superintend the cultivation of large estates, with the purpose of making as much money as possible and getting back to the home land at the earliest possible moment. As far as the population of the colony is affected, it is mainly by the growth of a body of half-breeds, who are always a troublesome class. Morals are low, and life unhealthy and artificial. In the political interests of the colonies similar distinctions exist. Life in a farm colony tends to develop enterprise, independence, and political and social equality. A feeling of patriotism toward the colony, as distinguished from the home state, inevitably develops. The manifest destiny of the farm colony is to become an independent state, either with a wholly separate government, or with only the most tenuous ties binding it to the home authority. In the plantation colony life develops along an aristocratic groove, with well-defined social and political classes. There is no love on the part of the colonist for the colony as such, and no body of local feeling grows up among the colonists. This development is furthered by the customary action of the central government, which regards the farm colony as of little importance because of the similarity between its products and her own, but devotes an enormous attention to the plantation colony because of the apparent importance of its unique products. Hence the farm colony is left free to develop along natural lines, while the plantation colony is subjected to all sorts of artificial restrictions and limitations which hamper its growth. As a result of all these factors, the plantation colony seldom achieves its independence, but remains subject to the home state indefinitely. Examples of farm colonies are the Thirteen Colonies, Canada, New Zealand, etc.; of plantation colonies, Java, Jamaica, Brazil under the Portuguese, etc. As will be seen, the farm colony has a peculiarly intimate relation with immigration movements.

This preliminary survey of the earlier forms of migration prepares the way for a clear understanding of the characteristic features of the fourth form. This is immigration, which in many respects differs from any other population movement. These distinctions merit emphasis.

In the first place, both of the two states concerned in an immigration movement are well established, and on approximately the same stage of civilization. Immigration can take place only over what Professor Sumner calls a single culture-area. Secondly, immigration is a distinctly individual undertaking. States may direct, control, regulate, or encourage immigration, but the motives which lead men into this form of movement are strictly individual ones, and the causes which arouse these motives are conditions which react upon the individual alone. The end sought is neither the advantage of the country of origin, nor of the country of destination, but the improvement of the condition of the individual.

The two countries concerned in an immigration movement resemble each other not only in the stage of culture but in climatic conditions and circumstances of life. There has never been any immigration between the temperate zones and the tropics, in either direction, nor have the polar regions ever figured. In fact, practically all immigration, historically speaking, has been between different countries in the temperate zone. But while there are these resemblances between the countries concerned, there must also always be some differences, otherwise there would be no motive for movement. The first and primary difference between the two countries is that the one which receives the stream of immigration is newer, and therefore much less thickly settled, than the other. Other things being equal, the chances for a comfortable living are greater in a country where the ratio between men and land is still low. This ratio between men and land is of extreme importance, and ought never to be neglected in the discussion of any sociological or economic problem.[[10]] It is especially vital as regards migrations, which are so directly connected with the shifting of populations.

Other differences which may be looked for between the two countries concerned in an immigration movement are the following: the country of destination is more democratic than the other, and its people enjoy greater social and political equality; there is more of individual freedom of conduct, and fewer traditional or legal restraints; military burdens are lighter, and there is greater latitude for religious belief and practice. On the other hand, life in the new country is likely to be more arduous, industry more insistent, the demands for personal ability more urgent. These features at once suggest those typical of the farm colony, and in point of fact we find that practically all countries which receive large streams of immigrants are developed farm colonies. These are, at the present time, the United States, Canada, Argentina, Australia, South Africa, and to a certain extent parts of Asiatic Russia.

The requirements, then, for an immigration movement are the following: two well-developed countries, one old and densely populated, the other new and thinly settled, the two on friendly, or at least peaceable, terms with each other. For immigration, even more than colonization, is a phenomenon of peace. On the part of the people who are to take part in the movement a high degree of civilization is demanded. They must be trained to act on individual initiative, and must have sufficient personal enterprise to undertake a weighty venture without an official or state backing. They must have sufficient intelligence to know about the objective point, and sufficient accumulated capital to enable them to get there. There must be adequate, easy, and inexpensive means of transportation between the two countries, in order to enable any large number of people to make the journey. The immigrant is not in any sense an adventurer or explorer. On the part of the nations concerned there must be a willingness to allow individuals to come and go at their own pleasure, without any extreme restrictions or regulations. There must be nothing of the old idea of the feudal bond between the person and the land.

From the above it appears that immigration must be distinctly a modern movement. Scarcely one of the foregoing requirements—not to speak of the conjunction of all of them—is more than three or four centuries old. Consequently immigration, in the sense in which we have defined it, has existed only for a comparatively short time, practically since the Discoveries Period. Moreover, it seems likely to be a purely temporary phenomenon. With the disappearance of the conditions which differentiate the countries which are now receiving immigrants from the older European countries, it seems probable that immigration will cease, for as far as the human eye can see, there will be no new lands to be opened up for the purpose.
