tion will be secured in even a bare majority of sites. Until the prob- 

 lem of reproduction is more thoroughly worked out, the policy should 

 be to remove only the dead and dying pifion trees for fuel, thus allow- 

 ing a careful management without encroaching seriously upon the 

 natural stands as is being done at the present time. It would seem 

 from the nature of the site that the stand could be made to succeed 

 best by the selection system, consisting of the removal of the dying 

 trees. The sale of this fuel with that of a large portion of the seed 

 should furnish a moderate income. This production would be low, 

 as contrasted with high-type coniferous forests in other regions, but 

 when consideration is given to the value of this species for fuel and 

 seed, the question of immediate returns is a minor one.
