THE PRESENT SITUATION IN FOR- 

 ESTRY, WITH SPECIAL REFERENCE 

 TO STATE FORESTRY 1 



No nation can prosper or even exist in com- 

 fort without wood, without a considerable sup- 

 ply of relatively inexpensive timber. Three 

 years ago our per capita annual consumption 

 of wood was about 300 board feet, exclusive of 

 large quantities used for fuel, paper and a 

 multitude of other purposes. It is extremely 

 difficult for our minds to picture what this 

 means in total volume or amount when multi- 

 plied by 110 million, our present population. 

 Each year we remove from our forests or de- 

 stroy through forest fires about 56 billion board 

 feet of timber large enough to saw into lum- 

 ber. This almost incomprehensible amount of 

 wood disappears from our forests every year. 

 Much of it we need and use, and can not very 

 well get along without. On the other hand 

 much of it is destroyed by fire. The latter is 

 not only a great immediate economic loss and 

 waste, but also an encroachment on supplies 

 that will be very much needed in the immediate 

 future. 



As a nation we have grown to our present 

 stature on a lavish diet of wood. We use more 

 wood than any other nation on earth. Our 

 industries would stop, our very civilization 

 stagnate were we suddenly deprived of our 

 wood supply. Wood the world over is a basic 

 resource. It is almost the first resource to be 

 exploited and utilized in the development of a 

 new country. Moreover, it is the resource that 

 makes possible the utilization of other re- 

 sources. There is scarcely an industry that can 

 prosper without wood. Agriculture, transpor- 

 tation and commerce as we know them to-day 

 are inconceivable without wood. All of us are 

 daily in contact with wood wrought into some 

 form for our comfort or necessity. From
