NOTES. 



1. Sugar Maple requires shelter and moist soil. 



2. The scarlet maple is a native tree along the borders of swamps, and 

 should only be planted near water. 



3. Box-Elder should only be planted as a temporary shelter belt on the 

 prairie. The tree is so badly infested with vermin that it should never be 

 planted as a street tree or about a residence. 



4. The Cottonwood should never be planted on high dry land. On the 

 borders of lakes and streams it grows to be a noble tree. Carolina Poplar 

 is a staminate form of the Cottonwood. 



5. Bolle's Poplar is a tall, fastigiate, silver-leaved tree, valuable when cau- 

 tiously used for landscape effect 



6. Basswood requires shelter and deep rich soil. On the prairies it should 

 be allowed to sprout freely and be treated as a shrub. 



7. White Pine should not be planted on the western prairies. It does 

 well in sheltered locations in the eastern half of the state.
