EVERGREENS. 271 



heat. A study of the tree in its native habitat 

 shows that it requires very little moisture either in 

 the soil or the air. It appears to be one well suited 

 for planting in the central and western portions of 

 the state. 



This tree grows in the higher altitudes of the 

 state, ranging from more than 5,000 feet above the 

 sea on Pine Ridge (in Sioux and Dawes counties) 

 to about 2,500 feet on the Niobrara^in Rock and 

 Keya Paha counties). On the North Platte it ranges 

 from nearly 6,000 feet (in Scott's Bluff county) to 

 about 3,500 feet (in Deuel county). In Custer 

 county it grows at an elevation of about 2,500 feet, 

 while in Valley and Greeley counties it descends 

 to about 2,000 feet above sea level. (Univ. Bulle- 

 tin No. 1 8. Prof. Bessy.) 



This tree must be handled with great care as it 

 is not easily transplanted. 



Mountain pine. (P. Montana or P. Mugho). Is 

 a dwarf species found growing throughout the 

 Rocky Mountains, and in Montana. Its foliage, or 

 needles are like the Scotch pine, and its expression 

 is that of a dwarf tree of that species. It grows but 

 a foot or little more in height, and spreads out by 

 the weight of its own branches bringing it to the 

 ground. It holds its color well in winter, and is 

 valuable for such situations on the lawn as require 

 evergreen bushes of this kind. 



Red Cedar. A medium, rather slow growing 

 tree that is well known. There are two species 

 found in the west, that, although quite closely
