1889;] In the Yellowstone Park 



contained trout and into which they might well be 

 introduced an investigation arranged for at the 

 request of Captain F. A. Boutelle, U.S.A., the local 

 commandant. On this expedition I had the in- 

 valuable assistance of Gilbert and, as a volunteer, 

 of Spangler, then librarian of Indiana University. 

 During the course of a month we made a fairly

 mapping and photographing the streams and listing

 course lay first along the left bank of the Yellow-

 to Heart and Shoshone lakes and the headwaters 

 of the Lewis Fork of the Snake, next down the 

 Firehole with its four amazing geyser basins to the 

 Gibbon, then over to the Gardiner, and from there 

 back to Mammoth Hot Springs. Progress was often 

 obstructed by complicated tangles of "down timber,"

 winter storms, but at night we camped in grassy 

 glades with which the forests are interspersed. 



Of all the noble scenery included in our great A painted 

 country, that of Yellowstone Park seems to me the cbasm 

 finest. With the most beautiful of our mountain 

 waterfalls set in a majestic painted gorge, a multitude 

 of charming lakes both large and small, dark forests 

 and symmetrical peaks, it is also everywhere per-
