di Garda, and the map of the Drau glacier and its neighbors, are the most 
complete, since they indicate the upper limits of glaciation by means of 
isohypsal lines. The data for such maps involve a vast amount of work 
such as it was not possible to extend over the entire Alpine field. As a 
rule each determination of the upper limits of glaciation required an_all- 
day climb. Penck once remarked, in the presence of the reviewer, that 
his ascents and descents of mountains in the Alps involve a distance suffi- 
cient to reach from the Alps to the South Pole, or from the Alps to the North 
Pole and back again. One who has not attempted Alpine work can scarcely 
appreciate the great labor involved in carrying out such a study as that 
accomplished by Penck and Briickner. The only serious defect noted in 
this publication is the absence of a general map of the entire Alpine region, 
though this is offset to some extent by the adoption of a uniform scale 
(1:700,000) for the several maps of the sections of the Alps. It is also to 
be borne in mind that even at the culmination of glaciation the Alpine region 
did not support a continental ice mass. The glaciers which became united 
on the Alpine foreland were of the Piedmont type, and many glaciers 
remained entirely independent throughout their course. 
Die Alpen im Eiszeitalter, although an expensive publication, the cost 
of the eleven parts being 55 Marks, or about $13.00, cannot well be left 
out of the library of any active geologist, and should be included in every 
university library. By those who have not a command of the German 
language a large amount of information may be obtained from the excellent 
maps, views, and diagrams.

The Life of a Fossil Hunter. By CHARLES H. STERNBERG. Intro- 
duction by Henry FAIRFIELD OsBorNn. New York: Henry 
Holt & Co. 
The author of this interesting personal narrative is one of the oldest 
vertebrate fossil collectors in America. Mr. Sternberg made his first 
expedition in the Kansas chalk for Professor Cope during the summer of 
1876. Specimens collected by him from many of the vertebrate-bearing 
horizons of the western United States are to be found in many of the 
museums of America and Europe. Beginning his work at a time when 
America had but three vertebrate paleontologists, Mr. Sternberg has seen 
the science advance until now there are over forty specialists engaged 
in it and to this advancement he has contributed not a little by his industry 
and skill as a collector. He has persevered in his chosen work in spite 
of hardships and financial difficulties. His wide acquaintance with paleon-
