also acquiring some of the physiological peculiarities of the 

 former. This blending of white and Indian blood is still fur- 

 ther confirmed by the varied composition of the Indian male 

 pupils in the Educational Home for Indian Boys in Philadelphia, 

 as is shown by the report of this institution for 1886. From this 

 source we learn that among the one hundred and seven boys 

 there were only thirty-eight full-blooded Indians ; of the re- 

 mainder one was three fourths, sixty-one one half, and seven were 

 one fourth white. Similar testimony comes from the reports of 

 the Commissioner of Indian Affairs. These reports not only 

 show the existence of a very large proportion of mixed bloods 

 among the 250,000 Indian population of this country, but also a 

 marked increase of the former during the years 1885 and 1886 — 

 the only years in which a record of the total number of mixed 

 bloods is supplied. Thus, in the year 1885 there were 18,412 

 and in 1886 there were 20,567 mixed bloods, an increase of more 

 than 2,000 during one year. The pure Indian population for the 

 former year was 259,244, and for the later 247,761, a decrease 

 of over 11,000 during the same time. 



It is furthermore evident from these reports that the number 

 of mixed bloods in each agency is very naturally determined by 

 the length of time which the Indians have been exposed to con- 

 tact with the white race, as is shown by the following table, 

 where are given the names of various agencies, the Indian popu- 

 lation in each one, the number of mixed bloods in each, the pro- 

 portion of mixed bloods to Indian population, and the dates of
