The second method of social stabilization in Latin America--Aryanization through wholesale European immigration--is exemplified by Argentina and Uruguay. Neither of these lands had very promising beginnings. Their populations, at the revolution, contained strong Indian infusions and traces of negro blood, while after the revolution both fell under the sway of tyrannical dictators who persecuted the white aristocrats and favored miscegenation. However, Argentina and Uruguay possessed two notable advantages: they were climatically white man's country, and they at first contained a very small population. Since they produced neither gold nor tropical luxuries, Spain had neglected them, so that at the revolution they consisted of little more than the port-towns of Buenos Aires and Montevideo with a few dependent river-settlements. Their vast hinterlands of fertile prairie then harbored only wandering tribes of nomad savages. During the last half of the nineteenth century, however, the development of ocean transport gave these antipodean prairies value as stock-raising and grain-growing sources for congested Europe, and Europe promptly sent immigrants to supply her needs. This immigrant stream gradually swelled to a veritable deluge. The human tide was, on the whole, of sound stock, mostly Spaniards and north Italians, with some Nordic elements from northern Europe in the upper strata. Thus Europe locked antipodean America securely to the white world. As for the colonial stock, it merged easily into the newer, kindred flood. Here and there signs of former miscegenation still show, the Argentino being sometimes, as Madison Grant well puts it, "suspiciously swarthy."[63] Nevertheless, these are but vestigial traces which the ceaseless European inflow will ultimately eradicate. The large impending German immigration to Argentina and Uruguay should bring valuable Nordic elements. This same tide of European immigration has likewise pretty well Aryanized the southern provinces of Brazil, adjacent to the Uruguayan border. Those provinces were neglected by Portugal as Argentina and Uruguay were by Spain, and half a century ago they had a very sparse population. To-day they support millions of European immigrants, mostly Italians and European Portuguese, but with the further addition of nearly half a million Germans. Brazil is, in fact, evolving into two racially distinct communities. The southern provinces are white man's country, with little Indian or negro blood, and with a distinct "color line." The tropical north is saturated with Indian and negro strains, and the whites are rapidly disappearing in a universal mongrelization. Ultimately this must produce momentous political consequences.
