x FOREWORD 



ficient investigation and forethought, and with reasonable 

 regulation, this resource can always be available to the peo- 

 ple of our country. 



Such achievements also have great meaning in regard to our 

 use of all renewable resources. Renewable is a really significant 

 word because soils, plant life including forests, animals, and 

 the waters that sustain them, all restore themselves naturally, 

 again and again, if we give them proper care. As we learn 

 more, therefore, of this living world upon which we depend, 

 our obligation is the clearer to use it well.
