FORESTRY AND IRRIGATION. 



30] 



Lumber Compan}' one of the chief ob- 

 jects in making a working plan was to 

 determine whether the present tract is 

 large enough to furnish a sustained 

 3'ield to the 3'earh' capacity of the mill, 

 and, if not, to estimate the additional 

 area necessarj^ to secure such a result. 



The conclusions reached in this work- 

 ing plan may be summarized as follows : 



The study made by the Bureau of 

 Forestry establishes the fact that the 

 application of practical forestry to the 

 tract of the Sawyer & Austin Liunber 

 Company would be a sound business 

 measure. It shows, furthermore, that 

 in the cheapness of logging, the value 

 of the product, the quick growth and 

 the ready reproduction of the timber 

 trees, and the practicability of inexpen- 

 sive and effective measures against fire, 

 the opportunity is a markedly favorable 

 one. 



The yield to be expected from cut- 

 over lands shows a high return from the 

 capital invested in them Cutting to 

 the advised diameter limit of 12 inches 

 breast high, or about 14 inches on the 



stump, with stumpage reckoned at $2 

 per 1,000 board feet, and the value of 

 cut-over land at $1 per acre, the aver- 

 age annual interest represented by the 

 future crop on cut-over lands is for a 

 period of forty years nearly 9 per cent. 

 In other words, after the Sawyer & Aus- 

 tin Lumber Companj^ have lumbered 

 their present tract at the rate of 14,- 

 500,000 feet per year, the lands which 

 have been cut-over will be producing 

 timber which, at a conservative esti- 

 mate, represents an income of 8.8 per 

 cent on the capital invested in them. 



It has been shown that, in order to 

 assure a sustained annual yield equal 

 to the capacity of the mill, the addition 

 of 170,000 acres to the present tract is 

 necessary. With this addition, or its 

 equivalent in stumpage, the Sawyer & 

 Austin Lumber Company can cut con- 

 tinuously 40,000,000 board feet a year. 

 If this addition is not made, it is clearly 

 unadvisable for the company to lumber 

 its tract upon the principle of a sus- 

 tained annual yield, since this would 

 fall short by about 25,500,000 board
