treated as a part of the mainland, while its names were applied to Isla Tassne or some other islet. Vide postea, p. 45.

(American maps, loc. cit., 4.) On the whole the cartography of a century indicates that the striking explorations of Ulloa, Alarcon, and Diaz were utterly neglected; it indicates, too, that Kino’s observations were promptly adopted, but that his erroneous identification of the island seen from Nazareno occasioned confusion; yet there is nothing to indicate definite knowledge of Escalante’s discoveries. Apparently the cartographic tangle began with the failure to discover the narrow strait traversing Seriland, coupled with hearsay notions of an insular Seri stronghold; it was complicated by Kino’s erroneous identification of the hearsay island; and it grew into the mapping of a traditional islet about the position of Tiburon, and the extension of the mainland into a peninsula embracing the actual land-mass of that island[77]—the islet lying about the site of the modern Isla Tassne, and often appearing under the name San Agustin.[78] Accordingly, so far as maps are concerned, Escalante’s discoveries were no less completely lost than those of Ulloa. [77] This cartography reappeared occasionally up to about the middle of the nineteenth century, as illustrated by the Greenhow map accompanying the edition of his history issued in 1845. [78] This condition is revealed in Mühlenpfordt, Versuch einer getreuen Schilderung der Republic Mejico, etc.; Hannover, 1844. * * * * * The recorded, history of the Seri Indians during the earlier two-thirds of the eighteenth century is largely one of zealous effort at conversion on the part of the Jesuit missionaries, who repeatedly approached the territory by both land and sea; yet the records touch also on events of exploration and on the characteristics of the tribe.
