 tree that can be used to a good advantage in the rocky, dry 

 soils and steep hillsides throughout the eastern part of the 

 state, and it is an especially valuable tree for planting through- 

 out the western part of the state. When planted in dense

stands of from 2000 to 3000 plants per acre, the trees develop

There are two distinct forms of this species. One form

 purposes mentioned. The other form is a dwarf type that 

 grow? very compact and symmetrical, and is prized highly for 

 ornamental planting. It is one of the most beautiful of our 

 ornamental evergreens. The two types are readily distin- 

 guishable in the nursery when the trees are two or three years

 for the purposes they best fulfill.

 can arbor vitse. The leaves are scale-like, closely appressed. 

 Through the summer they are deep green, changing with the
