wet weather, the small springs at the borders of the meadow would be 

 stronger, but the important facts are that there is no lake or even marsh 

 there and that neither Atlantic nor Pacific Creek has its rise in the 

 meadow. Atlantic Creek, in fact, comes into the pass as two good sized 

 streams from opposite directions and leaves it by at least four channels, 

 thus making an island of a considerable portion of the meadow. And it 

 is certain that there is, under ordinary circumstances, a continuous water- 

 way through Two- Ocean Pass of such a character as to permit fishes to 

 pass easily and readily from Snake River over to the Yellowstone, or in 

 the opposite direction. Indeed, it is possible, barring certain falls in 

 Snake River, for a fish so inclined to start at the mouth of the Columbia, 

 travel up that great river to its principal tributary, the Snake, thence on 

 through the long, tortuous course of that stream, and, under the shadows 

 of the Grand Tetons, enter the cold waters of Pacific Creek, by which it 

 could journey on up to the very crest of the Great Continental Divide, to 

 Tivo-Ocean Pass; through this pass it may have a choice of two routes to 

 Atlantic Creek in which the down-stream journey is begun. Soon it 

 reaches the Yellowstone down which it continues to Yellowstone Lake, 

 then through the Lower Yellowstone out into the turbid waters of the 

 Missouri ; for many hundred miles it may continue down this mighty 

 river before reaching the Father of Waters which will finally carry it to 

 the Gulf of Mexico— a wonderful journey of nearly t;,000 miles, by far the 

 longest possible fresh-water journey in the world. 



We found trout in Pacific Creek at every point where we examined it. 

 In Two-Ocean Pass we found trout in each of the streams and in such po- 

 sitions as would have permitted them to pass easily from one side of the 

 divide to the other. We also found trout in Atlantic Creek below the 

 pass and in the Upper Yellowstone where they were abundant. 



Thus it is certain that there is no obstruction even in dry weather to 

 prevent the passage of trout from the Snake River to Yellowstone Lake ; 

 it is quite evident that trout do pass over in this way ; and it is almost 

 absolutely certain that Yellowstone Lake was stocked with trout from the 

 west via Two-Ocean Pass.
