 top of the next as their gradually descending flight will carry them. 

 Before the middle of August, the migration is in full swing, and 

 flocks are seen each evening, passing over Sparta. Frequently 

 they alight in the streets and on the house-tops. I recall with a 

 smile the memory of a flock of a dozen or more which lit one 

 evening in front of the hotel. For a time pistol bullets and bird 

 shot made an accident policy in some safe company a thing to be 

 desired, but strange to relate none of the regular residents of the 

 town were injured. The same may be said of most of the grouse^ 

 though one, in the confusion, ran into the livery stable and took 

 refuge in a stall, where it was killed with a stick. 



Straggling flocks from south of Powder River prolong the fall 

 migration until near the first of October, after which none are 

 seen below the high elevations north of Eagle Creek.

 ados Islands. The group consists of four principal islands with 

 smaller outlying rocks, some of which are only completely sepa- 

 rated from the main islands at high tide. The largest, or South 

 Island, is a huge ridge some two miles long and of varying width. 

 The sides are precipitous and impossible to scale except at the 

 few favorable points. The backbone presents an irregular sky- 

 line like the back of a dromedary. The southern extremity, about 

 six hundred feet high, ends in a bold promontory. At the north 

 the ridge ends in detached rocks. A cove on the east side, about
