same land for the same length of time averages not more than $6 per 

 acre, it is evidently more profitable to devote the land to trees than 

 to wheat or corn, whether its value be $20 or $100 per acre. Thus, 

 if the comparison proves that forest planting is the more profitable, 

 silviculture in this region becomes a legitimate form of agriculture. 



SPECIES STUDIED. 

 HARDY CATALPA. 



In estimating the value of the products from the plantations of 

 hardy catalpa, first-class posts are assumed to be worth 12 cents each 

 and second-class posts 8 cents each. The material left after the posts 

 have been taken is estimated as cordwood and assumed to be worth 

 $2 per cord. The cost of establishing a catalpa plantation is placed 

 at $15 per acre.
