The U.S. Geological Survey of the Territories began in 1867 with 

 an examination of part of the Territory of Nebraska, and with a 

 grant of about 5000 dollars. Larger appropriations were made for 

 this excellent work, from year to year (75,000 dollars in 1872), and 

 the Survey was extended into the neighbouring Territories by more 

 and more completely furnished corps of geographers, geologists, and 

 naturalists. The publications of the Survey are Reports, Miscel- 

 laneous papers and books, and Bulletins in 8vo, and Palajontological 

 Contributions in 4to (of which eight volumes have been issued), also 

 some 4to volumes of Sections, Sketches, &c., and several Maps. 



The Annual Reports of the Geological Surveys carried on iu the 

 United States of America continue to prove most valuable exposi- 

 tions of the geographical, zoological, geological, and mineralogical 

 conditions of the several States and Territories successively treated 

 of; and they supply not only vast stores of facts, but carefully 

 elaborated opinions and theories for the Biologist and Physicist.

 headwaters of the Missouri, the Yellowstone, the Snake, and the 

 Kansas, togetlier with the neighbouring portions of the Rocky Moun-
