Big Trees, Calaveras Co. (hit. 38° 15', alt. 4,500 ft.), is in the heart 

 of the coniferous forest of the Sierra Islevada. In this locality the pines, 

 firs, cedars, and other conifers attain their largest size and most perfect 

 growth. Deciduous oaks constitute a very small part of the forest, but 

 they are mostly confined to the more barren spots. The climate at Big 

 Trees is agreeably temperate during a i)ortion of May, and throughout 

 June, July, August, and September. The winters are mild, considering 

 the altitude ; but snow, to a depth of one to four or five feet, usually 

 (50vers the ground, although some seasons the surface is bare for the 

 greater portion of the time. 



The summer avifauna of this locality resembles, to a considerable 

 extent, that of Soda Springs and Summit Meadows, the more notable 

 iibseutees being PinicoJa '■^ canadensis,''^ Hesperipliona vespertina, Zonotri- 

 chia, intermedia, Picicorvuscolumhianiis. and Picoides arcticus, all of which, 

 however, probably visit Big Trees at some time of the year. 



*More were probably present, as a gentleman told me a flock had hrcd there the 

 past season, on a level with Murphy's,
