Colorado Plateau region,— a district embracing portions of Utah, Colorado, 
New Mexico and Arizona — by Mr. Gilbert Thompson. In Colorado the field- 
work for a topographic map of the Ten-Mile Mining District has been finished, 
and the map completed, ready for the use of the geologist. In northern Nevada 
work has been commenced, which, in connection with previous surveys, will 
furnish a trusty map of northern and central Nevada. 
Mr. Arnold Hague is preparing a memoir on the Geology of the Eureka 
District, Nevada, and the study of the ore deposits of the same locaHty by Mr. 
J. S. Curtis has been finished so far as the field work is concerned. Mr. I. C. 
Russell, who has been studying the Quaternary lakes of the Great Basin, has com- 
pleted his examination of Lake Lahontan, and has made a preliminary one of 
southeastern Oregon. Mr. S. F. Emmons has begun the investigation of the 
mining and general geology of the Ten-Mile District and of the vicinity of 
Golden, Colorado, and attention has been given to the soils in the neighborhood 
of Denver. Mr. Lester F. Ward spent the summer of 1881 in the collection of 
fossil plants in Colorado and Arizona. Dr. C. A, White began at the same time 
the collection of a parallel suite of invertebrate fossils, but being called off to 
investigate the problem of artesian water on the plains, was compelled to post- 
pone it until another season. Prof, T. C. Chamberlin continued his work in 
examining and tracing the glacial moraines of Dakota and the associated features 
of the drift. Dr. Carl Barus, under the direction of Prof. Clarence King, has 
undertaken a series of experiments upon the chemical and physical properties of 
rocks and rock-forming materials under extreme conditions of temperature and 
pressure. 
The accompanying papers above referred to make up the great bulk of the 
volume, and are as follows : Birds with Teeth, by Prof. O. C. Marsh ; The Cop- 
per Bearing Rocks of Lake Superior, by Roland D. Irving; Sketch of the Geo- 
logical History of the Eureka District, Nevada, by Arnold Hague ; Preliminary

Beginning with the "log cabin and hard cider campaign of Tippecanoe and 
Tyler too" in 1840, the author takes his reader through the exciting poUtical 
history of the United States, down to 1872, the most important portion of the 
life of the Nation, since it includes the rise and progress of the slavery question, 
its settlement in the war of the rebellion and the reconstruction of the seceded 
States. During all this time, Mr. Julian was more or less actively engaged in 
politics and, for a number of years, in positions enabling him to command an
