Market Valuk of Lumber. 



The chief product of second-growth pine stands, as already men- 

 tioned, is round-edged box board lumber and match stock. In most 

 second-growth stands the lumber yield consists of two grades, both 

 round-edged : One-inch box boards or siding, worth from $12 to $15 per 

 thousand board feet, and If to 2£ inch box boards and match lumber, 

 worth from $17 to $18 per thousand. In addition, there may also be a 

 small amount of sash and blind stock, worth from $30 to $35 per 

 thousand. As the trees increase in size larger and consequently more 

 valuable lumber can be had, and the proportion of 1-inch siding di- 

 minishes . Thus, lumber from logs 5 inches in diameter at the small end 

 is made up of from 17 to 25 per cent of 1-inch siding, while in 10-inch 

 logs the proportion is less than 8 per cent, and in logs over 18 inches at 

 the small end it is negligible. The increase in value of the lumber from 

 second-growth stands up to 70 years of age is shown in Table 8. 1 The 

 values per thousand board feet are based on the values and the 

 approximate proportion of the various grades just mentioned. From 

 the values per thousand board feet and the board foot yields given 

 in Table 6, values per acre were obtained. The figures given in Table 8 

 are the approximate values of the manufactured lumber delivered at 

 the local market, and should not be mistaken for stumpage values, 

 which are these values minus all costs of exploitation.

1 There is reason to believe that by an early pruning and subsequent thinnings these values can be 

 greatly increased for rotations of from 50 to 70 years.
