THE GRAVES.

Cave 4. 



Beneath an enormous overhanging bowlder, in the same region as the graves already 

 described, we found a large irregular cave of two principal chambers, one of them leading 

 down four or five feet underground. These graves had perhaps been visited by treasure- 

 hunters or wild beasts, for the contents were strewn within and without the cave. Various 

 fragmentaiy and decayed bones, as well as many potsherds, were collected. From the latter, 

 two good vessels have since been restored, namely, a deep two-handled dish and a beaker- 

 shaped olla. The skeletal material includes six fragmentary human skulls, only two of 

 which (Ost. Coll. 3158 and 3159) are available for measurement. Five of these skulls are 

 evidently female, one of them probably so. One presents in a moderate degree the type of

artificial deformation most commonly practised in the highlands of Peru and Bolivia, and 

 another shows considerable fronto-occipital flattening. A quantity of fragmentary human 

 long bones and other skeletal parts found with the skulls add little or nothing to the story. 

 No bones of lower animals were collected except a weaver's pointed tool or bodkin i6 cm. 

 long (Ost. Coll. 3382), made by grinding to a point a llama's metacarpus or cannon-bone. 

 A better preserved implement of the same design is shown in Plate IV, figure 10. 



Cave 5. 



From this burial cave, which was excavated under Professor Bingham's supervision, and 

 which was only a few rods distant from the last described,' two human skulls were taken, 

 also a pair of femora decayed at the proximal ends, probably as the result of burial in the 

 contracted position, and one humerus. The only pottery that was collected was a badly 

 broken beaker-shaped olla.
