206 PRINCIPLES OF AMERICAN FORESTRY. 



i8. We have thirty acres of rather wet land which we 

 do not expect to use for many years except as pasture. 

 Would it pay to grow some White Willows on a portion 

 of it, and would they interfere with its value as pasture? 



Answer: If the land is not heavily pastured, it might 

 be a good plan to grow a few groups of willow on it, as 

 they will furnish some protection to the stock, and do 

 not interfere materially with the pasturage value of the 

 land. Scattered trees might also be gro\\Ti, as they would 

 not seriously interfere wdth the growth of grass under them 

 where the land is moist; but it would not be desirable to 

 encourage a very thick growth on the land, since it is much 

 more valuable for pastiu-age than it would probably be for 

 growing wood. 



19. B has come into possession of fifty acres of bluff 

 land along the Mississippi River, in Southern Minnesota. 

 The land is of good quality, but too much broken for 

 agriculture, and when used as pasture it washes badly. 

 The southern slopes are nearly bare of trees, but the 

 other slopes are well covered with White Oak, Hard 

 Maple, Basswood, and Elm, with some Hackberry, Wild 

 Black Cherry, Black Walnut, and Butternut. It has been 

 pastured for twenty years, and consequently there are 

 no young trees coming on. He desires to preserve it as 

 a wood lot, since it has become of little value for pasture. 



Answer: The first thing to do is to keep out the cattle, 

 as they destroy all the young seedlings that start, and 

 prevent any natural regeneration. In good seed years 

 it might pay to loosen the soil, where it could be done 

 easily, in portions that are not especially liable to erosion, 

 so as to give the seeds that fall a good chance to grow. 

 It would also be well to gather Black Walnuts and Acorns, 

 and plant them in especially favorable locations. Im- 

 provement cuttings should also be made where needed.
