Publisher's Synopsis
Excerpt from Possibility for Wood-Preservation Industry in Arizona: Research Report No. 11
A summary of the average number of poles per acre by di ameter and length classes to a -inch top diameter insule bark is shown in table 5. Three and two-tenths percent of the poles are Douglas - fir. From these data estimates can be made for poles of specific class and length. Since an indefinite num ber of poles could be produced from any single tree, varying in both length and class as the position of cut varies, it seems impractical to tabulate this composite array.
