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

1 Impossible to give, old table. 
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.
