Charlie, I'm impressed.

Woodman, I'm with you.

I had to cheat and go to the internet.

http://www.na.fs.fed.us/spfo/pubs/silvics_manual/Volume_1/pinus/sabiniana.htmDigger pine (Pinus sabiniana), also called bull pine or gray pine, has limited commercial use today, but it once was important to California Indians, who used its seeds and parts of cones, bark, and buds as food supplements, and its twigs, needles, cones, and resin in basket and drum construction
Currently, the tree's primary value is as a source of railroad tie material, with secondary values for box shook, pallet stock, and chips.
Normal heptane, an alkane hydrocarbon of rare occurrence in woody tissues, is the principal constituent of Digger pine wood turpentine and constitutes about 3 percent of needle and twig oil .
