CEOP PLANTS FOR PAPER MAKING. 19 



spruce used was less by 40,000 cords than in 1907, but the cost was 

 $2,000,000 greater. Present efforts in connection with the reforesta- 

 tion of spruce and pophir are not extensive enough to produce any 

 noteworthy effect upon the avaihible supply within a generation. At 

 the i^resent rate of increase in consumption, it will require between 

 15,000,000 and 20,000,000 cords of wood to satisfy the demand for 

 pulp and paper fiber in 1950. It will certainly be impossible to fur- 

 nish this from the forests. If every acre cut over each year were 

 reforested it would be twenty-five or thirty years, or possibly even 

 longer, before the trees could attain sufficient size to wairant cutting. 

 The forests can not recover fi^om the overdrafts continually being 

 made upon them; hence it is only a question of a limited number of 

 years until paper fiber must be grown as a crop, as are practically all 

 other plant materials entering into the economy of man. While the 

 conservation of only a few of the by-products of the farms yiekling 

 paper fiber can be accomplished profitably in the near future and only 

 a few plants promise to be money-makers immediately if grown solely 

 for paper production, it seems very probable that raw products now 

 scarcely considered may in a few years play an important part in the 

 paper and pulp industry.
