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.
