1 Three 10-acre plots. 
2 Blackjack and yellow pine calipered together. 
3 Includes Apache under ‘“‘ Total.” 
MAXIMUM STANDS. 
Figures for a number of the heaviest stands on the Forests in 
_ Arizona and New Mexico, on each of which the local officers selected 
the heaviest 10 acres that could be found, are given in Table 14. 
Trees above 12 inches breast high represent all that would ordinarily 
be merchantable under present market conditions if the stands were 
eut clean, while those above 18 inches represent the usual cut in a 
Government timber sale, subject, of course, to local variations. Even 
on these maximum stands the average number of trees per acre over 
12 inches in diameter is only 29.46 and over 18 inches only 19.438. 
Out of all the areas there was only one tree over 45 inches in diameter 
and only three trees over 42 inches. No trees were found which con- 
tained over five logs, although on the Apache Forest there were 31 
five-log trees on the 10 acres measured. Of blackjack over 26 inches 
in diameter, there was an average of only 0.27 per acre; over 12 inches, 
7.94; and over 18 inches, 2.39. 
What is probably the heaviest stand of pure western yellow pine 
in the Southwest is shown in Table 15. It consists of an irregular 
‘strip of 2 acres on the Tusayan National Forest. The trees are all 
long-boled yellow pine of good quality. The average of 35.4 trees 
per acre shows the unusual density of the stand, yet there are 11 trees 
with diameters over 30 inches breast high and 22 trees which will 
yield five logs.
