is the case. Value will be given to them by the work of 
future investigators. They form what will be the beginning 
of an extended series of measurements on a large scale, and 
their chief importance will arise from their position in the 
series. So far the measurements have not been so 
complete as the subject demands, or as it is my intention 
yet to make them. Moreover, only city children, and 
only a comparatively few children from a single city, have 
been examined. After information with regard to town 
children has been collected, there yet remain to be examined 
the children: of the bush; and pos:ibly the bush child 
may differ essentially in his characteristics from the child 
whose sky is mapped by roofs and chimneys. Even among 
the bush children themselves, there may be typical differ- 
ences. Climate and associations set their mark on the 
human family. 
“ As the soil is, so the hearts of men,” 
and the child of the plains may be of one type, the child of 
the uplands of another, and the one born and reared in the 
rich moist regions of the Eastern sea-board may develop 
into a type differing greatly from both.
