This project was supported in part by cooperative funds 

 furnished by the Northeastern Forest Experiment Station, 

 Forest Service, U.S.D.A. The idea for this study originated at 

 the Northeastern Forest Experiment Station. It has partially 

 supported two graduate students, one of whom was the junior 

 author, Richard D. Hopkins, Resource Economics. The other 

 was Arthur Bradbury of Forest Resources who developed the 

 initial compilations on white pine plantations.
