Illustrations of the “Tiburon canoe” (or balsa), drawn by H. Von Bayer, were also introduced.[202] In addition Mr Von Bayer succeeded in obtaining two photographs of Seri Indians, taken on shipboard; one of these is of special interest in that it illustrates the peculiar attitude of the Seri archer in the act of using his weapon.[203] [202] Ibid., pl. XV, p. 136 (one of these illustrations is reproduced in figure 28). [203] The negatives of these pictures were retained by Mr Von Bayer, and have been kindly turned over to the Bureau of American Ethnology. Unfortunately the archery negative had been shattered, but enough of the fragments were preserved to show all essential details and to afford a basis for the drawing reproduced in plate XXIX. Unfortunately the surveys were confined to the coast, and the interior remained unmeasured and unmapped save on the basis of tradition and travelers’ tales, supplemented by a few vague itineraries and traverses. Except along the international boundary and the railway (Ferrocarril de Sonora), the locations of pueblos and ranches remained guesses, the delineation of mountains remained a work of imagination, and even the best cartographers continued to run in rivers at random or in such wise as to afford artistic effect.[204] [204] The imposing official map of 1890, titled Carta General de la Republica Mexicana, formada en el Ministerio de Fomento con los datos mas recientes, por disposicion del Secretario del Ramo, General Carlos Pacheco, engraved and printed by Erhard Hermanos, Paris, on a scale of about 32 miles to the inch, represents Rio Bacuache as about the right length and with its center in about the right location, but as running at almost exactly right angles to its actual course; and it contains divers other equally startling errors. * * * * *
