It is a far cry from the explorer of fifty years ago measuring 

 his lumber visually from a mountain tree top to the trained 

 man of the present day measuring individual trees with cali- 

 pers. The change which has brought about this contrast in 

 measuring forest values has brought many new standards and 

 methods, and will continue to evolve towards the maximum 

 of intelligent effort in forestry.
