being attributable to stages in the general recession of the North 
American ice-sheet when increased snowfal] and onflow of the ice slack- 
ened its retreat or caused it temporarily to re-advance. Under this 
view, the Ice-Age seems probably to have comprised only one great 
epoch of glaciation, with moderate oscillations of the ice-front, and to 
have been geologically brief. Plistocene Phenomena in the Region 
Southeast and East of Lake Athabaska, Canada, J. B. Tyrrell, Ottawa, 
Can. The paper was the result of an exploration conducted by the 
writer during the past summer in the hitherto unexplored region lying 
southeast of Athabaska Lake and north of Churchill River. The 
region has some strongly marked glacial features. The writer dis- 
discussed the striation and character of the rock surfaces, the occurrence 
of till, drumlins, kames, and other glacial phenomena, Some high- 
level beaches, terraces, and other post-glacial deposits were also noted.

clay. Divergent strie on underlying rocks. The materials of the 
boulder-clay from the north. Intercalated stratified portions and their 
fossils deposited in the sea. Sections at Fern Ledges and Negrotown 
Point given. The conclusions are that the climate was Arctic or sub- 
arctic; that the boulder clay here was formed by a number of suc- 
cessive accretions in a zone of oscillation of the ice-front, and that its 
upper portion at least was thrown down when the lands stood atom
