Land and Human Migrations.

The article informs that modern students of human migrations set out initially with two categories of human movements. These they label as modern and prehistoric. Conclusions about the latter must necessarily be good guesses, but a good guess is permissible in any science where evidence from current observations is available for making generalizations and comparisons. Of the social, human interactive forces governing prehistoric migrations, nothing certain is known. But in the consideration of modern migrations much is known and may be deduced- Students have, therefore, divided modern migrations into various categories. Thus, in the modern sense, we may find religious movements, political movements, aggressive wars, and adventuring as categories of human migrations. Modern movements may be classified broadly as social and practical. The latter type of migration is brought about by population pressure, famine, drought, and similar natural phenomena. The former type includes such movements as those brought about by a search for political refuge, those instigated by labor recruiting, and by religious migrations. But there are factors basic to all human migrations which this paper attempts to deal with as initial phases of study. The logic is based on two major assumptions: that all men wish to survive; and that all men need land for-survival.
