CHESTNUT IN TENNESSEE. 



27 



18 inches, more than twice the volume called for in the specifica- 

 tions is consumed. In trees below 15 inches in diameter the waste 

 largely lies in the unused upper length of the stem ; in trees above 

 16 inches, the waste is in the diameter in excess of that called for 

 in the specifications. 



Table 6 Cubic contents of trees of various diameters, cut to a 

 4-inch top diameter, average number of ties per tree, and average 

 waste in clear length. 



Note * Specifications require four cubic feet. 



Table 7 gives the number of pole ties 8.5 feet long by 7 by 9 

 inches wide, which can be cut from trees of different heights and 

 diameters. The number of oak and locust ties in trees of different 

 diameters are shown in the last column. Both the oak and locust 

 yield fewer ties than chestnut from trees of the same diameter on 

 account of their thicker bark and shorter, more crooked, and more 

 tapering stems. The proportion of oak and locust ties in the stands 

 is less than 33 per cent.

 (8.5 feet long by 7 by 9 inches) in trees of different heights and 

 diameters.
