I arrived at Big Trees May 3, 1877, and by May 10 nearly all the 

 summer residents had arrived. Some of them had preceded me. Many 

 of them, especially the Warblers, were seen on the route from Murphy's 

 to this place. 



The spring of 1877 was earlier than that of 1878, the winter of the 

 former year having been very dry and mild. This probably accounts 

 for the difference in the arrivals of some of the birds, as shown by the 

 following figures. Probably I did not see some of them until some time 

 after their arrival, especially if rare.

Soda Springs, Placer Co.— This place is on the North Fork of the 

 American River, ten miles south of the Central Pacific Railroad, on the 

 west side of the " divide," or crest-line, of the Sierra Nevada; Lake 

 Tahoe being on the east side, ten or fifteen miles distant. Altitude of 

 the springs, 0,009 feet; the latitude, 39° IP. The mountains between 

 this place and Lake Tahoe rise 2,500 or 3,000 feet higher. This is above 

 the region of deciduous oaks, the trees being all evergreens, except a 

 species of dwarf maple and a few alders, willows, and aspens, which 

 grow along the river. It is a rugged, almost desolate, region, though 

 an interesting one. Grouse and Mountain Quails are comparatively 

 plentiful, and trout-fishing is quite good. The Warblers are well repre- 

 sented here: I have" found here the young of Dendrceca auduboni, D. 

 occidentalism D. nigrescens^ Hehninthophaga ruficapilla, H. celata, and other 

 species. 



On frosty mornings in September, birds were exceptionally numerous 

 in a few of the more sunny glades along the river, consisting chiefly of 

 J unco orcgonus, Spizella breweri, 8. socialist Zonotrichia intermedia, Pas- 

 serella megarhyncha, Pipilo chlorurus, Varus montanus, Dendrceca audti- 

 Ik> n't, etc., etc. The Humming-birds fled when the first frost killed the 

 flowers.
