Deducting the cost, $3.56, from the present value, $180.13. leaves 

 $126.57 as the net value, which is equivalent to an annual net income 

 of $3.29 per acre, not to mention the rental value of the land as a hog 

 pasture. It will be noted that the annual yield of Plantation No. 1 is 

 higher than that of No. 2. 



SILVER MAPLE. 



Silver maple ranks fourth in abundance among the planted trees 

 in eastern Nebraska. It is hardy throughout the region, though it at- 

 tains its best development on the lowlands. It is, in fact, not well adapted 

 for upland planting, but it succeeds there somewhat better than either 

 Cottonwood or willow. 



Silver maple should be planted mainly for shelter and frewood. 

 There are better trees, however, for both purposes. Its fuel value is con- 

 siderably higher than that of cottonwood or willow, but its yield is much, 

 less than either. 



BOXELDER. 



Among the planted trees, boxelder ranks third in abundance, yet its 

 place in economic planting is more limited than that of silver maple. 

 Usually, whever it will succeed, some more valuable tree could be grown. 

 It has been used for fence posts, and farmers and ranchmen say it is 

 somewhat more durable in contact with the soil than either cottonwood 

 or willow. However, on account of its branchy habit and tendency to 

 crookedness, only a small percentage of the trees can be expected to 

 make posts. Its fuel value is somewhat higher than that of cottonwood 

 and not as high as that of willow, but its yield per acre in a given time 

 is considerably less than either. Perhaps the chief economic value of 

 this species is for use as a nurse for some of the better trees, such as 

 walnut, or for shelter and shade. Its rapid growth and branchy form are 

 in its favor for windbreak planting, and as a shade tree it has com-, 

 mendable qualities. It is very hardy and easily propagated. 



RUSSIAN MULBERRY. 

 Russian mulberry has a limited value in forest planting, especially on 

 the dry uplands in the southwestern counties. It can not be planted with
