This table must be considered tentative, since it is based upon re- 
sults from but 65 trees. Yet it clearly shows that increase in diameter 
means an increase in the percentage of the better grades. In other 
words, a twofold gain is made by not cutting trees of small diameter— 
both an increase in volume and an increase in the percentage of the 
better grades. The steady increase in the percentage of clears and 
shop is especially noteworthy. Even a tree from 19 to 21 inches in 
diameter cuts only 7.5 per cent clear, select, and shop, and 92.5 of 
common and dimension. In comparing the relative grades (clear) 
cut from yellow pine and blackjack, it was found that for yellow pine 
the average per cent was 8.4, but that for blackjack only 3.4 per cent. 
Table 25 shows the relative percentage of grades, including shop and 
better, sawed from yellow pine and blackjack.

According to the best available statistics the cut of western yellow 
pine in Arizona and New Mexico for the first six months of 1909 was 
8,407,672 board feet and 11,540,854 board feet, respectively. If these 
figures are correct, it proves that at that time the timber industry 
had not yet recovered from the hard times of 1908, since Table 26, the 
result of a census collected by Forest supervisors in Arizona and New 
Mexico, shows that in the period between July 1, 1909, and June 30, 
1910, the output increased considerably.
