MINIMUM DIMENSIONS OF PEELED POLES. 



Sawtimber Second-growth sprout stands will seldom give any 

 heavier yield of large saw timber than seedlings of the same age, 

 since the rate of growth of sprouts eventually declines and becomes 

 less than that of seedlings. Sprout stands are best suited to the 

 product' on of smaller stems than those required for the best saw- 

 logs. Sprout timber, however, can very well be sawed into ties, and, 

 in addition to the ties, several boards can be obtained from the 

 larger logs. 



Table 10 shows the yield in board feet, both on the basis of the 

 Doyle-Scribner log scale and on the bas : s of the actual mill cut, 

 which can be obtained from stands of different qualities at different 

 ages. It lso gives the supplemental yield in cords of extract wood 

 from tops and from trees below 10 inches in diameter, and the total 

 value of the stands at different ages. These tables are based on 

 132 sample plots.
