EDITORIAL COMMENT. 
PLEISTOCENE GEOLOGY OF NORTHERN AND 
CENTRAL ASIA. 
Prof. George Frederick Wright, of Oberlin, Ohio, and liis 
son, Fred B. Wright, returned home about April ist from a 
journey around the world, chiefly for geological observation, 
which occupied somewhat more than a year. Their route was 
by the Southern Pacific railway to California ; thence to 
Hawaii, Japan, and China, leaving the city of Peking after the 
beginning of the Boxer massacres, from which they encounter- 
ed much delay and peril , by the Siberian railway, passing lake 
Baikal, and traveling the vast Russian empire to St. Peters- 
burg; thence through the region of the Volga, and of the 
Black and Caspian seas, to Armenia and Palestine ; thence l\v 
the Mediterranean and southern Europe to England ; and 
thence by Boston and New York to Oberlin. Attention was 
given principallv to Pleistocene geology, and to the absence or 
presence of evidences, of glaciation. Professor W^right on 
March 6th, at a meeting of the Geological society of London, 
presented a paper on "Recent Geological Changes in Northern 
and Central Asia," from which the more important of his ob- 
servations are summarized as follows in an abstract published 
in the Proceedings of that society. 
"The result of six weeks spent in Japan was to show that 
there are no signs of general glaciation in Nippon or Yesso.
