After the Tasmanian strain, Imbelloni carries over by land a Melanesian type to lay their skulls in Lagoa Santa, Punin, Texas, and Lower California. Next came tall people, “comparable partly to the Australian type,” who seem to be the Indians of plains and pampas. These were the last of the land-borne migrants until the present era. Hereafter they came by sea. The fourth element was a Proto-Indonesian people that settled exclusively in South America and mainly in Amazonia. With the fifth group Imbelloni presents the first frank Mongoloids, round-headed and inclined to agriculture; they settled in the Southwest, in Middle America, and along the Andean coast. An almost identical people—whom Imbelloni calls the Isthmid—spread through the center of the same area shortly after the birth of Christ and brought to fruition the civilizations which Cortez and Pizarro found in the New World. To top off his list, Imbelloni brings over the Eskimo and men for the American Northwest—but by no longer a sea voyage than Bering Strait.[24] Gladwin’s theories appeared first in the second volume of _Excavations at Snaketown_, and were presented in altered and amplified form through his rather antic book _Men Out of Asia_. They are completely heretical, completely fascinating, and in some respects uncommonly plausible. They are certainly a tonic. Gladwin begins with what might be called a Pygmoid visitation. He does not dignify it with the word “migration.” He is careful to say that there are only “rather vague indications.” There is “just enough to make one wonder if there may not have been a few Pygmy groups who strayed over here long, long ago and were pushed off to the edges and the ends when the Australoid tide flowed in.”[25] If a scientific study is ever made in the Guayana highlands of Venezuela, some support may be given to the theory of an early Pygmy migration. Carl Sauer on a visit to Venezuela in 1946 saw photographs of a Pygmy-like people taken by a Venezuelan army officer who had paddled and packed the Guayana River for some years. This tribe, which does not interbreed with other tribes, appears to be Pygmoid in stature and type. Further, it lacks “clothing, weaving, netting, baskets, boats, and fishing skills, and also houses.”[26] Australoids, Negroids, and Men from Europe
