THE WINDBREAK AS A FARM ASSET. 



15 



highly valuable post producer as well as an almost impenetrable 

 windbreak. This species yields a return of from $8 to $30 per acre, 

 the largest returns being secured by cutting at about 10 years of age. 

 It requires good moisture conditions and is unable to withstand 

 severe winter temperatures. 



Silver maple returns from 72 cents to $1.54 per acre, the largest 

 amounts being obtained from windbreaks about 25 years old. The 

 species is used chiefly for fuel. 



AVhite pine attains its best value only when grown to log size. 

 This may be reached in windbreaks in 30 years or a little longer. 

 The annual value of the growth is about $4 or $5 per ncre, according 

 to the market for the timber. 



Scotch pine has not as high a value for lumber as white pine ; on 

 most farms the fuel value is greater than the lumber value. This 

 tree is capable of producing returns of from $2 to $4 worth of fuel 

 per acre on moist soils. A very sandy soil will not hinder its growth. 



These estimates indicate that it is advisable to treat the windbreak 

 as an asset and to give it the same care as the other productive agents 

 on the farm, so that it may become a source of revenue as well as a 

 comfort and a protection.
