were made with especial reference to the future production of an exact 

 model in plaster of the whole group. 



On the homeward route, which was by the way of the Upper Yellow- 

 stone, across the headwaters of the Snake to the Wind River and thence 

 via Camp Brown to the railroad, a number of very effective views were 

 made, particularly about the Grand Falls and the canon of the Yellow- 

 stone. At the Yellowstone Lalie some very fine views were made, but 

 that region was not completed, in consequence of a prolonged snow-storm. 



At the Togwotee Pass some characteristic views were obtained of the 

 remarkable breccia mountains, whose castellated forms adorn that por- 

 tion of the continental divide, and also some of the curious '"bad lands" 

 farther down on Wind River. The season's work closed at Camp BroAvu, 

 where portraits and groups were made of the Bannock prisoners in con- 

 finement at that post. 



A brief summing up of the season's operations of three months, much 

 of which time was characterized by extremely inclement weather, shows 

 an increase to the already very extensive collection of the survey, of 45 

 negatives 11 by 14 inches in size, and 110 of smaller ones, 5 by 8. 



Publications.— During the year 1878 the publications of the United 

 States Geological Survey have been numerous and important, yielding 

 in no respect to those of any previous year, and fully sustaining the 

 reputation this organization has acquired for the ])rompt and lull exhibit 

 of its operations. Eleven separate publications have appeared and others 

 have been brought to a forward state of preparation. 



Perhaps the most important of these as a contribution to pure science 

 is the seventh volume of the quarto reports. This is Prof. Leo Lesque- 

 reux's beautiful monograph, " The Tertiary Flora," forming a compan- 

 ion volume to the same author's " Cretaceous Flora," which latter con- 

 stitutes the sixth volume of the series. It consists of nearly 400 pages, 

 and is illustrated with 65 x)lates. 



A further contribution to the fossil floi-a- of the West has been made 

 in the publication of 20 plates, entitled " Illustrations of the Cretaceous 

 and Tertiary Plants of the Western Territories of the United States " 

 This volume consists only of the plates and explanatory text, the fnil 

 report upon the subject being deferred. 



The regular annual report of progress for the year 187G, being the 

 tenth of this series, appeared during the past year. This makes a vol- 

 ume of about 550 pages, illustrated with 79 plates and various wood- 

 cuts. There has also been issued in pamphlet form the preliminary re- 

 port of operations for 1878, in advance of the regular report for that 

 year. 



The Miscellaneous Publications' Series has been continued during the 

 year by the issue of oSTos. 10 and 11. Miscellaneous Publication No. 10 

 consists of a Bibliography of North American Invertebiate Paleontology, 

 prepared by Dr. C. A. White and Prof. II. Alleyue Nicholson. Miscel- 

 laneous Pirblication No. 11 is entitled " The Birds of the Colorado Val-
