der it of most extraordinary interest. I can say but little of the fauna 

 and flora of the National Park. Elk, moose, deer, antelope, mountain 

 sheep, bears, wolves, wild cats, lynx, rabbits and porcupines, with 

 some beautiful foxes, were all we obtained. Birds were scarce, and 

 of only fifteen species, including an abundance of ducks, geese, swans 

 and sag'e hens. We were too late for summer flowers, and generally 

 the whole of the sylva of the park consist of a pine, red fir, spruce, 

 one species of cottonwood, and the ever-present quaking aspen; 

 scrubby willows and some insignificant bushes of Rhus and Coriuis 

 comjjlete nearly the whole list. 



Completing our surveys in the Park, we turned to the west again, 

 reached Henry's Lake, and tried to follow the west side of Henry's 

 Fork to Snake River. Baffled in this, we traveled westward to Cam- 

 ass Creek, reached the regular stage road at Beaverhead Canon, 

 and finally reached Fort Hall and Portneuf River October 19-20, '78. 

 During this whole journey I have made continued examinations for 

 arch;eological relics, but had very little success until we reached 

 Upper Madison Fork. Here and around Henry's T^ake, Henry's Fork 

 and Beaverhead Canon, and on Market Lake and 

 Snake River I have gatliored some very character- 

 istic obsidian implements which 1 transmit to the 

 Academy for illustration. [Figs. 1 and 2.] 



T have always understood, until within a few 

 years, that the presence of obsidian weapons in 

 Kansas, Colorado, Nebraska and Wyoming, and 

 in Utah also, was due to the probable intercourse 

 Fig. 1. Nat. size. of exchange from the Lidians, or we may say Az- 

 tec races, of Mexico, with the more northern tribes. I am satisfied 

 that whatever obsidian arrows, lance heads and leaf-shaped imple- 

 ments I have found in Colorado, Wyoming. Nebraska, etc., were 

 more probably derived from the Yellowstone and from Snake River 

 rather than from New and old Mexico. Obsidian implements begin 

 to abound fi-om Great Salt I^ake northward ; and on Portneuf and 

 Snake and Henry's Fork of Snake River, in the National Park, and 

 on Madison Fork ; its abundance everywhere, both wrought and un- 

 wrought, ceased to become extraordinary or noticeable. 1 have 

 been assured by reliable, trusty residents of Idaho and Utah Territo- 

 ries that even to this date, not farther back than fifteen to twenty 

 years ago, they have repeatedly seen the Bannock and Snake In- 

 dians of that region make themselves arrow heads of obsidian.
