_Chulpas_, generally of square or rectangular form, consist of a mass of unhewn stones faced outside with blocks of trachyte or basalt, painted red, yellow, or white. A very low door, always facing east, as if in honor of the rising sun, gives access to a cist in which the dead was laid. The _chulpa_ of our illustration (Fig. 105) is situated near the village of Palca; it rises from an excavation four feet deep; its height is about sixteen feet, and the cornice consists of _ichu_, a coarse grass which grows in abundance on the mountains, and which after being firmly compressed was cut with the help of sharp instruments. The human bones, which were mixed together in the greatest confusion, made a heap in the sepulchral chamber more than a foot high. The mounds of Ohio also cover over sepulchral chambers of a peculiar construction, being often formed of round pieces of wood, five to seven feet long by five to six inches in diameter; near the bodies were placed a few ornaments, chiefly copper ear-rings, shell beads, and large flint knives. Most of the skeletons lay on the bare earth; but one exception is mentioned in which the ground was paved with mussel shells. A remarkable discovery has quite recently been made at Floyd (Iowa), the account of which in Nature for January 1, 1891, we will give in the words of Clement Webster: “In making a thorough exploration of the larger mound … the remains of five human bodies were found, the bones even those of the fingers, toes, etc., being, for the most part in a good state of preservation. First, a saucer or bowl-shaped excavation has been made, extending down three and three-quarter feet below the surface of the ground around the mound, and the bottom of this macadamized with gravel and fragments of limestone. In the centre of this floor five bodies were placed in a sitting posture with the feet drawn under them, and apparently facing the north. First above the bodies was a thin layer of earth and ashes, among which were found two or three small pieces of fine-grained charcoal. Nearly all the remaining four feet of earth had been changed to a red color by the long-continued action of fire.” Mr. Webster goes on to describe the various skeletons and says of one of them, that of a woman: “The bones in their detail of structure indicated a person of low grade, the evidence of unusual muscular development being strongly marked. The skull of this personage was a wonder to behold, it equalling if not rivalling in some respects and in inferiority of grade, the famous Neanderthal skull. The forehead, if forehead it could be called, is very low, lower and more animal-like than in the Neanderthal specimen…. The question has been raised how was it that these five bodies were all buried here at the same time, their bodies being still in the flesh.” … Webster adds that the probability is that all but one of them had been sacrificed at the death of that one, who had most likely been a chief.
