far enough from others to retain its body limbs, 
through the life of the tree. Owing to the 
tapering character of the cone (suggesting its 
botanical name), the cones are not pushed off, 
but often the wood-layers seize and cover the 
cones from sight. 
It is not strange that this lovely little pine 
is a favorite in cultivation, a long hillside 
being planted with them like an orchard in 
the lower end of the experimental grounds at 
Berkeley. Managers of experimental grounds 
elsewhere in the state are growing them by 
the thousand and distributing as desired, for 
reforesting the foot-hill region, especially 
where denuded by hydraulic mining. The 
Narrow-cone Pine is a member of the Tenaces 
group, along with the Monterey Pine, having 
persistent cones and leaves in threes, but the 
cone is narrower, pointed, and the scales on 
the outer side terminate in conical, curved 
spurs instead of rounded knobs. 
Another contrast is found in the characters 
of the true Nut Pines of the arid interior 
regions, the cones smftll, nearly globular, 
strongly knobbed, and containing large, wing¬ 
less, oily, and delicious seeds. There are four 
species; practically but one of them, the 
Single-leaf Pine (P. monophylia ), reaches 
California on the southeastern flanks of the 
Sierra and on the desert exposures of the 
San Bernardino' Mountains. In early times 
the nuts of these trees, called Pinyons, then 
abundant on the hills of Nevada, formed a 
large part of the aboriginal food, but later 
the miners and stock men have nearly ex¬ 
terminated the Indian orchards. The Pine 
Nuts of commerce are the product of another 
species in New Mexico. <1
