Note.—Localities given with two !! I have not visited myself. I would also further remark that I am by no means sure of having correctly determined the two oaks—Quercus Douglasii and Garryana.
It may not be altogether amiss to offer some observations on the distribution and value, as specimens, of some of our trees which I have met with on my various trips over a portion of this State.
1. Pinus Sabiniana, Dougl. (Digger Pine.)
Invariably disposed over south-hillsides of the interior, occupying the driest expositions—Mount Diablo! Russian River Valley! Geysers! Auburn and Forest Hill! San José Valley! Near Mission San Antonio!! Mountains east of San Diego!!
As to its value there are a great many contradictory assertions made by farmers; some assert it yields an excellent wood for yokes and similar objects, while others denounce it as entirely useless.
2. Pinus Lambertiana, Dougl. (Sugar Pine.)
Pine Mountains near Geysers! Near Cloverdale! Forest Hill! Mountains east of San Diego!! Generally with Pinus ponderosa in groves, occupying the damper localities.
3. Pinus ponderosa, Dougl. (Yellow Pine.)
Russian River Valley! south of Clear Lake! Geysers! Auburn and Forest Hill! San José Valley! Blue Mountains!! (Mr. Dunn) Rocky Mountains!! New Mexico!!
