WILLOWS : THEIR GROWTH, USE, AND IMPORTANCE. 



49 



COST OF GROWING WILLOWS. 



Table 19 gives the cost per cord of growing willows on land of 

 different values, with different costs of formation, low, average, and 

 high yields, and different rotations. In this table compound interest 

 at 6 per cent is charged on the land value, the cost of formation, and 

 taxes. With a cost of formation of only $3 and a high yield the 

 actual cost of growing a cord of willows on land valued at $5 per 

 acre is 20 cents. Such a combination of conditions is exceptional, 

 however, and would rarely be encountered. A poor yield from land 

 valued at $100 and a cost of formation of $15 makes the cost of 

 growing a cord from $5.95 to $7.64, depending upon the rotation. 

 Except where the wood lot has a decided value for other purposes 

 than the wood crop itself the plantation is not justified by the returns. 

 Leaving out every other consideration except the value of the mate- 

 rial produced, it is poor business to grow willows when the cost is 

 greater than $2 per cord. This practically eliminates the use of $100 

 land for such a purpose unless a yield of 5 cords per acre is assured.
