The proportion of males to females is remarkably low among the 

 Apache proper, this condition being undoubtedly a result of the great 

 loss of males in the earlier years of their history by death in raids 

 and war or by capture. 



On the other hand, the excess of males is considerably higher 

 among the relatively pacific Rio Grande Pueblos, Papago, Maricopa, 

 Mohave, and Yuma, and from slightly to moderately higher among 

 several of the remaining tribes, than among the American whites. 

 This is an interesting condition, which calls for elucidation. 



Unfortunately, adequate and reliable statistics as to the proportion 

 of the sexes at birth and as to relative mortality are not yet obtain- 

 able. Limited direct inquiries by the writer show the following con- 

 dition as to births: 



Thirt3"-seven San Carlos Apache women beyond the child-bearing 

 period when inquiries were made^ had brought forth a total of, 

 boys, 53.49 per cent; girls, 46.51 per cent.

 some proportion of males belongingto Arizona were counted among the Htnh contingent of the tribe.

 met with during the studies. No difficulties were encountered in ol)lalning the answers, and, as every 

 living and dead child had to be specified, the opportunity for error, if any, was Iml slight.
