gravelly knoll, about the poorest soil in the plantation, and the 

 trees, as could be expected, are not at their best. Nevertheless 

 they have made a fair growth and now average 24 feet in height 

 and 'Z\Y\ inches in circumference. They are exposed to a 

 strong canyon wind, and have had some branches broken, and 



lean strongly 



away from the 

 wind current. 

 Their liability 

 to be deformed 

 by the wind, 

 and to suffer 

 from the at-

 green aphis, 

 are the chief 

 objections to 

 planting this

 recovers from 

 transplanting, 

 as it scarcely 

 has a tap root; 

 and it thrives 

 in most Utah 

 soils, though it 

 prefers a deep 

 rich one, and 

 will grow with 

 greater luxuri-

 cut back. The wood of the Elm is heavy, weighing 40 

 pounds per cubic foot, is close grained, and dark-brown in 

 color; it is not especially valuable. Figure 8 shows an eight- 

 year-old American elm growing near the Station.
