crossing Orange, Los Angeles, and Santa Barbara Coun- 

 ties, stretch several ranges of mountains in a westerly 

 direction, separating in more ways than one the warm, 

 dry, salubrious, but limited citrus region from the cooler, 

 better-watered portion of the State. 



On the highest one of the ranges the San Bernardino 

 Mountains a considerable body of Black Pine, inter- 

 spersed with Yellow Pine, abounds. On the lower part 

 of the south flank fine trees of the monster Big-cone 

 Pine are met with, and also that other prodigy of the 

 same nature the Big-cone Spruce both trees being also 

 found sparsely elsewhere, westward. 



In the higher valleys of San Bernardino and Gray- 

 back are stalwart, thick-trunked trees of the usually slim 

 Tamarack Pine, and on the south side of Mt. San Ber- 

 nardino, at an elevation of about 3,000 feet, occurs a thin, 

 interrupted belt of about 2 miles of the Narrow-cone 

 Pine the southernmost limit of this curious species. A 

 few trees of Sugar Pine and of the White-bark Pine 

 occur near the summits. The Nevada Nut-Pine reaches 

 the eastern, or congenial desert side of the mountains, 

 extending westward to the railroad pass of the Tehachape 

 Mountains. The California form of the Colorado White 

 Fir is rarely met with on the heights, and a few trees of 

 Douglas Spruce, Incense Cedar, and the two Junipers 

 Western and California complete the list. 



NORTHERN CALIFORNIA. 



Two widely separate and different mountain ranges 

 uphold the unequaled forest wealth of California. The 

 southern part of the Coast Range presents forests of 

 Bentham's variety of Yellow Pine, above which a few 

 Sugar Pines hangout their long pendent cones, while the
