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 small, 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. monophylla), 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.
