as well as the other small islands of the Lesser Antilles. In this view Bullbrook also concurs. Contrarily, Fewkes believes that the Caribs did not gain a foothold there, chiefly, it seems, because the typical stonework of the Lesser Antilles associated with the Caribs by Fewkes and other archeologists has not been found in Trinidad. There is a question, however, as to whether the stone artifacts referred to are actually Carib remains. In either event, there seems to be a sufficiency of historical evidence to demonstrate the reasonableness of Loven's theory.

Carter for unpublished information on the distinctions between the upper and lower strata of the Erin Bay site. 12 Rainey, F. G., "Scientific Survey of Porto Rico and the Virgin Islands," New York Acad. Sci., 18, part 1, 175 (1940). 18 Our understanding of this problem will be greatly advanced by stratigraphic analyses of the Erin Bay and Barrancas deposits. The Trinidad research, it is hoped, will soon be furthered by cooperation between Trinidad archeologists and the Yale Peabody Museum.
