40 R. Rueeres Gates AND Gro. E. Darsy.—Blood Groups and These people remain with the status of Indians although many of them appear to have more white than Indian blood. This is doubtless for the economic reason that as “‘ Indians,” although they do not receive “ treaty money” from the Canadian Government, yet they live on Reserves and are educated and looked after, which would not be the case if they ranked as white. The situation is very different as regards the negroes of mixed breed, who have no such incentive to remain classed as negroes but who “‘cross the colour line’ whenever opportunity offers. Similar conditions regarding the Indians hold throughout Canada. In Nova Scotia there are probably no Micmac Indians of pure blood left, but there are numbers of mixed bloods on reservations and in special Indian schools, who would furnish material of great interest for a study of race crossing. It would appear that while the British Columbia coastal Indians have rather rapidly absorbed white blood, yet living on reservations and being able to continue to a considerable extent their former occupations or others of a similar character, they have remained contented and have made remarkable progress in the adoption of the ways of civilization, even to electric light, motor boats and other modern inventions. In this respect they are comparable with the half-breeds between Ojibway Indians and whites studied some years ago (Gates, 1928) in the Temagami region of Northern Ontario. These conditions appear to be much more satisfactory from the point of view of making the most of the Indians’ potentialities than those recently described by Mead (1932) on an Indian reservation apparently in the vicinity of Oklahoma. The American government gave Indians enfranchisement as a nominal gesture of equality, but divided up the reservations so they were obliged to become individual landowners. The cupidity of the white man frequently resulted in the Indian losing part or all of his land and with it his livelihood ; or if he lived off rents, prodigality of spending for a short time was often followed by complete loss of economic status. Moreover, the entrance of white men into the reservations as owners or renters of land obtained from the Indians helped to complete the break-up of any possible transition from native to civilized ways of livmg. The type of education offered a primitive and simple-minded people appears to have been equally inappropriate to their status and needs. These are examples illustrating the need for an anthropological approach to problems connected with the administration of native races. The Canadian census shows an increase in the “ Indian” population of Canada, but it needs to be recognized that this is a case of assimilation with white blood mainly in the more remote parts of the Dominion. The number of individuals classed as Indians has doubtless increased but the number of pure blood is steadily decreasing, and a considerable proportion of those ranking as Indians more nearly resemble whites in their appearance. As has been argued elsewhere (Gates, 1928), this dilution of the Indian blood with white produces a type probably having greater intelligence and energy than the pure Indian—a type which is well adapted to the active life of a hunter or fisherman in the less populous parts of the country. Summary. Blood tests of 300 British Columbia coastal Indians gave results as indicated in Table 1 {p 24). The tests included members of the Haida, Kwakiutl, Salish and Nootka tribes. Only
