to be. A third heavy log is placed over the butts of the two projecting 
logs. Then two more logs are put on top of the preceding one with their 
ends into the bank, and thus a foundation is built up to the level of the 
embankment. This is covered with a platform, and the house is built 
about eight or ten feet back from its outer edge, so that the platform 
forms the front portion of the floor of the house, and also a walk leading 
to the house-door. 
Ill. Tae Growrs or INDIAN CHILDREN FROM THE INTERIOR OF 
British CoLuMBIA. 
The table below shows the results of a compilation of the rates 
of growth of Indian children of the following tribes :—Ntlakya’pamug, 
Shuswap, Okanagan, Kalispelm, Yakima, Warm Springs. I have com- 
bined all these tribes, because the adults have very nearly the same 
stature, and because the geographical environment is very much alike. 
The numbers of individuals are rather small, but nevertheless a few 
results of general interest may be deduced from it. i 
It will be noticed that in the eleventh, twelfth, and thirteenth year's 
girls are taller than ‘boys. This agrees closely with the period during 
which the same phenomenon takes place among the whites, and is later 
than among the Indians of southern latitudes. The decrease in variability 
is not very well marked, probably because there is a considerable uncer- 
tainty in regard to the estimated ages of the children. Still, it appears 
that there is a distinct drop in the fifteenth year in boys, and in the 
thirteenth year in girls. Among the Mission Indians of Southern Cali- 
fornia this drop takes place between the thirteenth and fourteenth years 
in boys, between the ninth and eleventh years in girls. Among the white 
children of Massachusetts the drop takes place between the fifteenth and 
sixteenth years in boys, between the fourteenth and fifteenth years in 
girls—i.e., nearly at the same time as, or a little later than, among the 
Indians of British Columbia.
