Second Annual Report of the State Forester of Minnesota. 

 By W. T. Cox. St. Paul, Minn. 1913. Pp. 61, ill. 



The original forest area of Minnesota was 33,000,000 acres. 

 The area now bearing tree growth comprises 28,000,000 acres, of 

 which approximately 15,000,000 acres are of rough, stony or very 

 sandy land, which will always remain in forest. The annual 

 growth in the forests of the State is probably not more than 

 2,000,000,000 board feet, being less than the amount cut each 

 year. With better fire protection this yield can be doubled. 

 There are several million acres of young, rapid-growing pine, 

 spruce and other timber in the northern and north central part 

 of the State, and this is the kind of timber which suffers most 

 from fires. The Forest Service, through patrol and otherwise, 

 has reduced the fire risk 40 per cent.
