CERTAIN SAND MOUNDS OF 



Of 73 perforations, 41 are from the right side and 32 from the left. The 

 excess of percentage of perforation in female humeri, originally remarked by Broca, 

 holds good in this case as in Thursby Mound, to which reference will be made later. 

 In that mound, however, humeri in the uncertain class show perforations exceeding 

 the imperforate in number, which is not the case here.

Arrow and Lance Points. — Five arrow and lance points were met with during 

 the last investigation. Of these, four were found separately on the base, and one 8 

 feet from the surface in the lower, or white sand layer. 



Implements of Polished Stone. — At different points on the shell base were seven 

 hatchets or chisels of stone, "celts" so called, from two to four inches in length, the

smallest being roughened on three sides. In caved sand from the upper layer was 

 a "celt" 5 - 5 inches in length. The majority of these implements were of a ruder 

 type, less smooth, with cutting edge less truly ground than specimens from many 

 mounds of the river. 



On the shell base was found an implement of polished stone somewhat resem- 

 bling a hammer, rounded and roughened at either end (Fig. 19). 



This style of implement, the common type of the pueblos, has not been met 

 with elsewhere by us in the river mounds. 



Near by lay two polished " celts," one in a fragmentary condition.
