lively succession of single photographs each one of which shows 
its strong traits. The editors understand this and they wish the 
reader also to bear it in mind. While the (Ikolouist as a journal, 
is responsible for all that is said l)etween its covers, the separate 
editors must be considered responsible in the first instance onlj' 
for what the}- may contribute; but, secondly, they share in the 
joint responsibility of the anonymous articles. The former they 
cannot repudiate, but the latter they may disclaim in any way 
the}' choose. It is manifest that this secures for the journal the 
largest possible result from a composite editorship, and yet 
yields to every editor the right of such individual person- 
alitj' as he may choose to assert irrespective of his asso- 
ciates. 
The editors wish to take this opportunity to again express 
their obligations to the geologists of America. Without their 
co-operation it were vain to attempt to sustain such a magazine 
in America. The editors feel encouraged, and even flattered, b}' 
the cordiality and generosity with which the journal has been 
received. While it has not yet reached a self-sustaining finan- 
cial basis, it has come very near to it, and the editors are confi- 
dent that in the near future with a continuance of the favors of 
the past it will pass that mark.

This work is partly an abridgment and partly an extension of tlie 
author's previous larger volume, "The Ice Age in North America." 
Glaciers and ice-sheets now existing are described in the first three 
chapters, special attention being given to the Muir and Malaspina 
glaciers in Alaska and tlie ice-sheet and glaciers of Greenland. The 
next two cliapters are devoted to the Pleistocene glaciation of North
