The almost total absence of human remains has frequently been remarked, and the theory is advanced that cremation must have been practiced. We have no evidence, however, of such a custom among the historic tribes of this region, and, besides, such elaborate tombs would hardly be constructed for the deposition of ashes. Yet, considering the depth of the graves, their remarkable construction, and the character of the soil selected for burial purposes, it is certainly wonderful that such meager traces of human remains are found. Pinart surmises, from the analogies of modern burial customs upon the north coast, that the bones only were deposited in the graves, the flesh having been allowed to decay by a long period of exposure in the open air. This, however, would probably not materially hasten the decay of the bones. Mr. Merritt states that human hair was obtained from graves at Bugaba, and that he has himself secured the enamel of a molar tooth from that locality. De Zeltner tells us that in three varieties of graves remains of skeletons are found, always, however, in a very fragile condition. One skull was obtained of sufficient stability to be cast in plaster, but De Zeltner is not certain that it belonged to the people who built the tombs. Mr. McNiel reports the occasional finding of bones, and a number of bundles of them are included in his collection. He reports that there are no crania and that nothing could be determined as to the position of the bodies when first buried. Pinart observes that in some cases the bodies or remnants of bodies were distributed about the margin of the pit bottom, with the various utensils in the center, and again that the remains were laid away in niches dug in the sides of the main pit. These scattering observations will serve to give a general idea of the modes of sepulture practiced in this region, but there must be a closer record of localities and a careful correlation of the varying phenomena of inhumation before either ethnology or archaeology can be greatly benefited. PLACING OF RELICS. The pieces of pottery, implements, and ornaments were probably buried with the dead, pretty much as are similar objects in other parts of America. The almost total disappearance of the human remains makes a determination of exact relative positions impossible. The universal testimony, however, is that all were not placed with the body, but that some were added as the grave was filled up, being placed in the crevices of the walls or pillars or thrown in upon the accumulating earth and pebbles of the surface pavement. The heavy implements of stone are rarely very far beneath the surface. OBJECTS OF ART.
