maple for permanent and the l)ox older for quick

 attained useful size. 



(1 Space trees on the highway according to the 

 spread of their crowns at maturity. Taking the su- 

 gar maple as an example with a spread of crown of 

 ;>-"> feet from the stem we see that a spacing of less 

 than seventy feet will permit the interlacing of 

 branches, which is not desirable with highway trees; 

 therefore, a safe spacing for sugar maple is 85 feet 

 with trees on the opposite side of the highway to 

 alternate. A planter may determine the safe high- 

 way planting distance for any species by measuring 

 the crown spread of a fully mature specimen of that 

 species and adding ten feet to the result. 



In general the soil variation gives to the highways 

 of Michigan an opportunity of rare worth for the 

 production of a large variety of trees and shrubs of 

 highly ornamental and utilitarian value. 



Why Minnesota Should Have More State 

 Forest Lands 



P. O. ANDERSON 



The "pinch" of the lumber shortage is now felt, 

 and it behooves the people of the state to read "the 

 hand-writing on the wall." The American farmers 

 or business men who are the most successful usually 

 study the economic situation and sense the coming 

 changes and need long ahead of their neighbors. Tt 

 is very evident to all who have studied the situation 

 that greater timber conservation and reforestation 

 policies must be induced, to avoid the timber shortage
