Henr\ S. Drinker, LL.D., President of Lehigh University, and President of the American Forestry 



Association. 



"Conservation does not consist in hoarding our natural resources. Perhaps the best 

 definition ever given is that attributed to Dr. C. W. Hayes, when Chief Geologist of the 

 U. S. Geological Survey, to the effect that Conservation is ' Utilization with a maximum 

 efficiency and a minimum waste.' In taking wise and broad measures to avail best of our 

 undeveloped natural resources, the need is not so much to withdraw and set them aside 

 for the use of future generations, when other resources may have been developed, as to 

 be sure they are not wasted in their use by the present generation." 



Henry S. Drinker. 

 President American Forestry Association.
