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

 summer residents liad arrived. Some of tliein had preceded me. Many 

 of tliem, especially the Warblers, were seen on tlie route from Murpby'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, especiallj^ if rare.

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

 American Eiver, ten miles south of the Central Pacific Eaiboad, on the 

 Avest 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, G,009 feet; the latitude, 39° 11'. 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 feAV 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 Bendroeca auduhoni, IK 

 occidentalism I>. nigrescens, HelminthopliagarujicapiUa, H. celata, and other 

 species. 



On frosty mornings in September, bmls were exceptionally numerous 

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

 Junco oregonus, Spizella brewen, 8. socialis* Zonotrichia intermedia., Pas- 

 serella megarhyncha, Pipilo chlorurus, Parus montamts, Bendroeca audn- 

 honi, etc., etc. The • Humming-birds fled when the first frost killed the 

 flowers. 



Certainly both species. — L. B.
