Based on taper curves; S2aled mostly as 16.3-foot logs, with a few shorter logs where necessary. 

 Stump height 1 foot. Diameter inside bark of top, 6 inches. 

 Data collected by T. S. Woolsey, jr., in Grafton County in 1903.

Scaled "straight and sound" in tree lengths cutting to a diameter outside the bark of 6 inches. If logs 

 are cut to a limit of 4 inches in the top, trees under 10 inches will scale about 10 per cent more; those over 

 10 inches about 1 per cent more. 



Based on the measurement of 579 trees made by T. S. Woolsey, jr., in 1903.
