This view has been emphasised afresh by Fewkes[777], though of recent years it has met with vigorous opposition. At the conclusion of his article "Die melanesische Bogenkultur und ihre Verwandten[778]" Graebner attempts to trace the cultural connection of South America with South-east Asia rather than with the South Seas, the main links being represented by head-hunting, certain types of skin-drum and of basket, and in particular three types of crutch-handled paddle. According to him the spread of culture has taken place by the land route and Behring Strait, not across the Pacific by way of the South Seas, a view to which he adheres in his later work. An ingenious and detailed attempt has also been made by Pater Schmidt[779] to trace the various cultures determined for Oceania and Africa in South America. Apart from the great linguistic groups usually adopted as the basis of classification, Schmidt would divide the South American Indians according to their stage of economic development into collectors, cultivators, and civilised peoples of the Andean highlands. Though this series may have the appearance of evolution, in point of fact "each group is composed of peoples differing absolutely in language and race, who brought with them to South America in historically distinct migrations at all events the fundamentals of their respective cultures.... As we pass in review the cultural elements of the separate groups, their weapons, implements, dwellings, their sociology, mythology, and religion we discover the innate similarity of these groups to the culture-zones of the Old World in all essential features[780]." The author proceeds to work out his theory in great detail; the earlier cultures he too considers have travelled by the enormously lengthy land route by way of North America, only the "free patrilineal culture" (Polynesia and Indonesia) having reached the west coast directly by sea[781]. W. H. Holmes[782] draws attention to analogies between American and foreign archaeological remains, for example the stone gouge of New England and Europe. He hints at influences coming from the Mediterranean and even from Africa. "Even more remarkable and diversified are the correspondences between the architectural remains of Yucatan and those of Cambodia and Java in the far East. On the Pacific side of the American continent strange coincidences occur in like degree, seeming to indicate that the broad Pacific has not proved a complete bar to intercourse of peoples of the opposing continents ... it seems highly probable considering the nature of the archaeological evidence, that the Western World has not been always and wholly beyond the reach of members of the white, Polynesian, and perhaps even the black races."
