[120] The dimensions given by Gen. J. H. Simpson, _Reconnoissance_, etc., pp. 79-82, of the pueblos--"Pintado," "Bonito," and "Peñasca blanca"--on the Rio Chaco vary, as far as the circuit is concerned, between 1,200 and 1,700 feet, "about." Dr. W. H. Jackson, _Geographical Survey_, etc., 1876, has measured these ruins, and gives the following dimensions: "Pueblo Bonito," 544 × 314; "Peñasca blanca," 499 × 363 (only 3 sides of the rectangle being built up); "Pueblo Pintado" (2 sides), 238 × 174; "Pueblo Alto" (3 wings), 360 × 200 and 170. "Pueblo Bonito" therefore alone comes up to the standard of Pecos. The latter, however, is larger still, as, by adding to the perimeter given that of the northern annex (about 90 m.--295 ft.), we obtain a total of 450 metres, or 1,480 feet. The difference, if any, is not considerable; and I merely advert to the fact to show that the old ruins of New Mexico, comparatively neglected, are fully as important in size as any of those further north, besides being completely identical in plan, structure, and material. Furthermore, the pottery is identical. This was already recognized in 1776 by Father Silvestre Velez Escalante, _Diario y Derrotero de los Nuevos Descubrimientos de Tierras á Rumbos N. N. Oe. Oe. del Nuevo México_, MSS. at the Library of Congress, fol. 118, on the San Buenaventura (Green River), and in his letter, dated Santa Fé, 2 April, 1778, _Documentos para la Historia de México_, 3a série, vol. i. p. 124. [121] _On the Ruins of an Ancient Stone Pueblo on the Animas River_, Peabody Reports, 11 and 12. [122] I must here call attention to a singular coincidence. Among the ruins of Uxmal in Yucatan there are, aside from the "Teocalli," or medicine mound, two general forms of structure,--one narrow rectangle like _B_, and hollow rectangles like _A_. The "Casa del Gobernador" would correspond to the former, and the "Casa de las Monjas" to the latter. Of course, there is dissimilarity between the house of the "Governor" and _B_, in so far as the former contains halls and the latter but cells. Still the fact is interesting that, whereas the great northern pueblos have each but one house alone, here, for the south, we have already two buildings within one and the same enclosure, similar in form and size to those of Central America. I call attention to this fact, though well remembering at the same time the friendly advice of Major J. W. Powell, the distinguished chief of the Bureau of Ethnology at Washington, "not to attempt to trace relationships." [123] _Relation du Voyage de Cibola_, ii. cap. v. p. 176. [124] I am informed by Governor Wallace, and have permission to quote him, that these elevated plateaux grow exceedingly tall wheat, rye, and oats. He has seen oats whose stalks were 6 feet long and 1-3/4 inches in diameter. The heads were proportionally large. [125] He became adopted, as I am told, from being, as a boy, assistant to the sacristan of the church of Pecos.
