 more than 75 board feet per acre. Under conservative forest man- 

 agement it could eventually be raised to at least 400 board feet per 

 acre and the quality of lumber correspondingly improved. The pres- 

 ent yearly cut of lumber is 213,000,000 feet board measure, and 

 according to the census figures for 1907, just published, there is a 

 falling off in the timber cut from previous years, which indicates 

 that the maximum production has been reached due to the exhaustion 

 of nearly all of our virgin timber and that from now on, or at least
