and corn. How or where they secured their supply of water, who 

 they were, or where they went — each may form his own idea." 



When I came to examine the material referred to at the com- 

 mencement of this article, I found that it represented one human 

 skeleton and a few parts of a second one, such as an extra mastoid 

 process of a temporal bone of the right side of a skull. There may 

 be other pieces belonging to this latter skeleton, but of that I am 

 not quite sure, as the fragmentary condition of the whole renders it 

 practically impossible to decide as to that. The extra mastoid 

 process is larger than the other two at hand, and apparently came 

 from the skull of a larger individual than the rest would indicate. 

 It is probably from the skull of an adult male subject. 



There are some 150 pieces or more of the skeleton to which the 

 balance of the material belongs. Apart from some of the phalanges 

 of the hands and feet and other small bones, these are all more or 

 less imperfect — in most cases extremely so. 



As bones, they all exhibit the usual evidences of great age and, 

 in some instances, of having been broken up long ago — as in the 

 case of certain bits of the calvarium, where the fractured edges are 

 considerably worn, thus rendering it impossible to associate them 

 correctly. All of these pieces are of a very pale clay color, almost 

 white, and extremely friable and brittle. Even the shafts of the 

 largest long bones may easily be broken with one's hands alone. 



The only restorations that it was possible for me to make are here 

 shown in Plate XIX and in Plate XXI, fig. 17. The skull and 

 mandible are shattered into many little bits, and such bones as the 

 sphenoid and others are broken up to such an extent as to make it 

 difficult to recognize the parts — even with a perfect skull at hand 

 for guidance. Except a very few fragments, the entire vertebral 

 column and pelvis are missing, and I find no pieces that would suggest 

 any portion of the hyoid bone. One clavicle is in fairly good con- 

 dition (Plate XX, fig. 8), but most of the ribs are very fragmentary. 

 No part of the sternum seems to be present, and if it is, the parts 

 have been crumbled beyond recognition. This appears to be likewise 

 true of the scapulae. 



With respect to the long bones of the extremities (Plate XXI, 

 figs. 17-22), I find the middle thirds of the shafts of the femora, with 

 their extremities and the rest, missing. There are also similar 

 remains of the humeri, the ulnae, the radii, tibiae, fibulae, and so on; 

 but no other bone nearly as perfect as the humerus I restored in 

 Plate XXI, fig. 17. The crests of the tibiae are far from being what
