handbook in the stone trade of Wisconsin. While it is prepared 
primarily in the interests of the stone industry of Wisconsin, it has 
much of general interest to persons outside of the state, and both Dr. 
Buckley and the director of the Wisconsin Geological and Natural 
History Survey are to be congratulated on presenting to the public 
such an interesting, attractive and valuable contribution on the sub- 
ject of building stones.

Macmillan Company, pp. 502, 8vo. 1899. Amply illus- 
trated. 
In this work there is brought together a vast amount of experi- 
mental and experiental data relative to the physics of soils and their 
relations to water and air. ‘These data are given in both their ana- 
lytical form in the shape of tables, diagrams, and other modes of scien- 
tific expression, and in their concrete industrial form as exemplified in 
growing crops and in drainage and irrigation appliances. The treat- 
ment is very clear and specific and at the same time very compact. It 
is a conspicuous example of mu/tum in parvo, if 500 close-set pages do 
not make the expression inapplicable. The author has personally 
studied the irrigation systems of Europe as well as those of this coun- 
try, and has himself conducted careful experiments bearing on the 
fundamental principles involved. While thoroughly practical in its 
bearing, the treatment is firmly controlled by the scientific spirit. It 
is an admirable blending of good science and good technology.

This paper deals almost wholly with economic interests of a very 
local character ; and yet it is not without some facts of general interest. 
It is a description of a coal field of very limited extent situated on the 
coast of Oregon 200 miles south of the Columbia River. The coal is 
of Eocene age. Fossils of fresh and brackish water type are found in
