APACHE PINE (pinus engelmannii)
CHIHUAHUA PINE (Pinus leiophylla)

UNKNOWN

These hard pines occur only in Southern Arizona and Mexico. Nothing is known of them specifically as bearing trees. In the dry climate in which they occur they should be satisfac- tory. Being somewhat smaller and twisted in form than most other pines it is probable that the blaze should be kept to a minimum and painted thoroughly to forestall weathering.
