of reckless waste iu this valuable natural resource is 

 stopped. 



The French use 25 cubic feet of lumber each year per 

 capita ; the Germans, 37 ; and the people of the United 

 States, 260. We are cutting nearly three times as much 

 timber as is being produced. At the present rate of 

 consumption and reforestation, it has been estimated 

 that our timber supply will last only until 1950. 



Dr. Van Hise gives the following suggestions for con- 

 serving our timber. 



(1) We must reduce waste in cutting. 



(2) We must reduce waste in milling and manufacture. 



(3) We must reduce loss in turpentining. 



(4) We must preserve the life of the timber by preservative 



treatment. 



(5) We must utilize by-products. 



(6) We must reduce fire losses. 



(7) We must reforest areas burned over. 



(8) We must maintain forests or essential areas. 



(9) We must maintain areas stocked so as to produce larger 



growth. 



(10) We must battle with insect pests. 



(11) We must substitute other products for timber. 



(12) We must reform our tax laws.
