it becomes more urgent, for timber is the slowest of all crops to

the other hand, there is not much latitude of choice, for America 
must have timber, and the only way to get the amount needed is to 
grow it. Our timber supply and our wheat supply stand in the same 
category. There is no doubt that whatever may be necessary to 
insure the continued growing of wheat will be done. The restoration 
of American forests awaits only the impulse of a clean-cut public 
conviction that timber is essential and that a new crop must be grown.
