i82 • The American Geologist. February, 1005 
This book is uniform with Dodge's Elementary Geography which 
was noticed in the Geologist (vol. xxxiv, p. 197), and compares well 
with its pi'edecessor in all of its points of excellence. N. H. W.

The progress of the geological surveys of the states, and par- 
ticularly that of the United States Geological Survey, has made such 
books as this possible to the American student. As these surveys 
have led to a more detailed, as well as a more systematic, examin- 
ation of the features of the land, they have resulted in a mass of 
geological and geographical information which, as yet, is very large- 
ly confined to the original official reports. It is the task of Dr. Brig- 
ham to reduce this information to more simple terms and to bring 
its final results into sharp and comprehensive expression and in- 
dividual use, and at the same time to make the student an inter- 
ested, if not an eager, inquirer in pursuit of geographical knowl- 
edge. No young person can go through the exercises required by 
this categorical inquisition without becoming not only a good 
geographer but a fairly good geological observer. N. H. W.

a special preface for the English translation. 
We had occasion to notice the French translation of this great 
work (vol. T) in vol. 27, p. 56, of the Geologist. The work of 
course is the same, in an English garb — so closely the same that 
it has adopted the great fault of the original, i. e., the lack of an 
index. 
At the opening of chapter V (p. 173) is the following statement: 
"Precise investigation shows that a measurable displacement of 
any fragment of the rocky crust of the earth, with regard to another, 
whether it takes the form of elevation, subsidence or horizontal dis- 
placement, has not yet been convincingly established." This seems 
to call in question the evidence on which many important geological 
principles have been based, such as block mountains and all fault- 
ing. We are reassured, however, by the following sentence with 
which the same paragraph closes: "But if movements do not actu- 
ally take place before. our eyes, yet numerous dislocations show 
that they have often occurred on the grandest scale, and frequent 
earthquakes prove that they are not yet at an end."
