GEOLOGICAL SUEVEY OF THE TEKRITOEIES. 7 



entire party were the recipients of all the assistance we needed or 

 the post could supply. To my excellent friend, General H. A. Morrow, 

 in command of Camp Douglas, Utah, 1 am indebted for many favors, 

 not only as an officer of the Army, but as an earnest and successful stu- 

 dent of geology, in the form of valuable specimens and much informa- 

 tion. To the officers of the railroads and stage-lines my party was 

 much indebted the past season. To Mr. Bradley Barlow, and Gilmer and 

 Salisbury, proprietors of the stage-routes in Idaho and Montana, our 

 thanks are due for passes for two persons. 



I beg to call the special attention of the Department to the great 

 generosity of the officers of the Union Pacific Eailroad, Hon. Thomas 

 A. Scott, president, and General T. E. Sickels, superintendent, for free 

 transportation for my entire party from Omaha to Ogden, and return. 

 Mr. H. Brownson, general freight-agent of the Union Pacific Railroad, 

 ordered our freight to be carried at reduced rates. My thanks are also 

 due to the officers of the Central Pacific Eailroad for free passes for 

 several members of my party. 



It would not be possible to mention by name, all the kind friends in 

 the West who showed my party valuable attentions. With scarcely an 

 exception, we were received with great favor in every portion of the 

 country. I would express my thanks to Hon. B. F. Potts, governor of 

 Montana, Hon. H. L. Hosmer, Hon. J. Y. Lovell, of Virginia City, and 

 many others. 



I wish also to express my obligations to the gentlemen connected 

 with the press, who have never failed to recognize the importance of 

 these surveys in the development of our western Territories. 



I desire to acknowledge the numerous favors and aid which have 

 always been extended to myself and party in all our labors by 

 Professors Henry and Baird, of the Smithsonian Institution, and to the 

 Engineer Bureau of the Army, for the use of their valuable maps for 

 several years past. 



To the editors of Scribner's Monthly, who have done and are continu- 

 ing to do so much to spread a knowledge of the remarkable scenery and 

 resources of the far West among the people, I am under obligations 

 for the use of some of the finest wood-cuts illustrating this report. 



As far back as 1856, when the writer was connected with the explor- 

 ing expedition to the Lower Yellowstone, under the command of Gen- 

 eral G. K. Warren, of the United States Engineer Corps, it was the plan 

 of that accomplished engineer and geographer to penetrate the unknown 

 but marvelous region of the Yellowstone Basin. Wonderful tales, that 

 had sharpened the curiosity of the whole party, were related by our guide, 

 Mr. James Bridger. An expedition was planned by General Warren 

 for the years 1859 and 1860, which contemplated the exploration of 

 this region as the objective point; but he was superseded in command 

 by Colonel Wm. P. Eaynolds, of the United States Engineer Corps. The 

 writer was also connected with that expedition as geologist. Every
