The Seri are distinguished by another trait hardly less striking than the pedestrian habit, and even more conspicuous than the tooth-and-nail habit with the correlative absence of tool-sense; the trait is not tangible enough for ready definition or description in terms (of course because so unusual as not to have bred words for its expression), but is akin to—or, more properly, an exceeding intensification of—race-pride in all its protean manifestations; it may be called _race-sense_. Like other primitive folk, the Seri are self-centered (or egocentric) in individual thought, i. e., they habitually think of the extraneous phenomena of their little universe with reference to self, as in the labyrinth of consanguineal relationship extending and ramifying from the speaker; furthermore, they typify primitive culture in their collective thinking, which is tribe-centered (or ethnocentric), i. e., they view extraneous things, especially those of animate nature, with reference to the tribe, like all those lowly folk who denote themselves by the most dignified terms in their vocabulary and designate aliens by opprobrious epithets; but the Seri outpass most, if not all, other tribes in dignifying themselves and derogating contemporary aliens. Concordantly with this habitual sentiment, they glory in their strength and swiftness, and are inordinately proud of their fine figures and excessively vain of their luxuriant locks—indeed, they seem to exalt their own bodies and their own kind well toward, if not beyond, the verge of inchoate deification. The obverse of the same sentiment appears in the hereditary hate and horror of aliens attested by their history, by their persistent blood-thirst, and by the rigorous marriage regulations adapted to the maintenance of tribal purity; for just as their highest virtue is the shedding of alien blood, so is their blackest crime the transmission of their own blood into alien channels. The potency of the sentiment is established by the unparalleled isolation of the tribe after centuries of contact with Caucasians, by their irreducible love of native soil, by their implacable animosity toward invaders, and by their rigorously maintained purity of blood; it is manifested in their commonplace conduct by a singular combination of hauteur and servility, forbidding association with aliens on terms of equality. The entire group at Costa Rica in 1894 were on good behavior, partly, no doubt, for profit, partly because they were at peace bought by bloodshed; yet they kept an impassable gulf between themselves and the Caucasians, and a still wider chasm against the Papago and Yaqui. They came to the tanque, usually in groups, rarely alone, always alert; especially when alone or in twos or threes, they moved slowly and stealthily in their peculiar collected and up-stepping gait, often stopping, always glancing furtively with roving eyes, and bearing a curious air of
