ORNITHOLOGY. 



Valley, we found the country along the western base of the Clover Mount- 

 ains to be similar to the upper portion of Ruby Valley in its general char- 

 acteristics. As along the eastern base of the East Humboldt range, the 

 streams from the main canons were of considerable volume, while their 

 bordering shrubbery continued with them across the valley to the river. 

 The shrubbery along the main streams of the Upper Humboldt valley was 

 more extensive and vigorous, however, the cotton-woods and aspens being 

 more numerous, and constituting extensive groves, other spots being occu- 

 pied by dense thickets of thorn-apple {Crat(Egm rivularis), wild-cherry 

 {PruHus andersonif), and willows (Salix, species). At this place the 

 following species were observed: —

30. Trout Creek, Upper Hmiboldt VaJlej/ (September 16-20. 1868).— 

 This locality was very similar to the last, a large bi'ook, with an accompany- 

 ing growth of shrubbery and thickets of small trees, extending across the 

 valley from the Clover Mountains to the Humboldt River, the plain itself 

 being covei'ed by the usual sage-brush plants; but the upper portion, next 

 to the lower foot-hills of the mountains, was clothed with rye-grass meadows, 

 interspersed with willow and aspen copses. In these rye-grass meadows
