Botany : This volume consists of “ Reports upon the botanical col- | 
lections made in portions of Nevada, Utah, California, Colorado,

The Catalogue is preceded by three short chapters of a more 
popular character, on the Colorado District, the New Mexican Dis- 
trict, and Economic Botany. An appendix enumerates the plants 
collected in California in 1875. A good index completes the work. 
“Asa rule, only the plants collected by the various parties of this 
Survey have been enumerated or described in this Report. In the 
masterly contribution on the Ferns alone has this rule been widely 
departed from.” This last is Prof. Eaton’s Ferns of the Southwest, 
a full report of all the Ferns discovered hitherto in the regions of 
the United States, lying west of the rosth degree of west longitude, 
and south of the goth degree of north latitude. As all the species 
and genera not found in Gray’s Manual, and even some of these are 
described in this report, it must be the standard reference at least 
till that magnificent work, the “ Ferns of North America” is com- 
pleted. Lieutenant Wheeler and Dr. Rothroch may well congratu- 
late themselves on the excellent dress in which this report is pre- 
sented ; the paper, the type, the engravings are all worthy of the 
scientific ability expended on the subject matter. 
_ We are tempted to arrange from the chapter on Arizona two 
contrasted pictures. 
The Black Mesa is really an island of verdure raised. up out of 
the more desert areas north and south of it. There the scene was
