It is well known that in America for the past twenty 
years, as formerly in Europe, the question of the Pleistocene 
age of man has divided geologists and anthropologists into two 
antagonistic groups. The writer has not participated in this 
dispute, having been occupied with other lines of geological 
research. It is true that when he found, in 1877, the quartz 
chips at Little Falls he considered them pre-glacial, i.e. pre- 
Wisconsin. In the literature of the lengthy discussion which 
has arisen concerning those chips and other reported discov- 
eries of glacial and pre-glacial man in America, will be found 
nothing further from his pen until 1902, when he had occasion 
to re-examine the Little Falls locality in the light of the re- 
sults of the Minnesota Survey touching the Pleistocene geol- 
ogy of the state. In a chapter in "Kakabikansing," by J. V. 
Brower, the writer abandons his first announced opinion and 
refers these chips to that 'period when the ice was still in the 
central and northern part of Minnesota, while its dissolution 
maintained a vastly swollen river in the Mississippi valley at 
Little Falls. For Little Falls therefore these chips are post- 
Glacial, but for the state and for the general region, they date 
from glacial time, i.e. the closing stage of the Wisconsin epoch. 
The writer therefore approached the question of the age 
of the Lansing skeleton in an undisturbed and judicial frame-
