22 OUR NATIVE BIRDS 



Nursery men are likely to offer species which have been 

 introduced from Europe or Asia, but they will generally 

 answer just as well, provided they are hardy in the region 

 where they are wanted. The letters N., S., M., W., 

 mean that the respective plant is found or that the 

 genus is represented in the North, South, Rocky Moun-

1. Gray, Manual of the Botany of the Northern United States. 



Sixth edition.

3. Chapman, Flora of the Southern United States. Second edition. 



4. Coulter, Manual of the Botany of the Rocky Mountain Region. 



5. Whitney and Watson, Botany of California.

 flowers should be used much more for ornamental pur- 

 poses. Readers who may wish to know the more con-

 "The Wild Flowers of California." 



Both books are illustrated and are well adapted to the 

 purpose they intend to serve, and show that hundreds 

 of our wild flowers deserve a place in our parks and 

 gardens. 



Our schools in observing Bird and Arbor Day, or 

 Nature Day, should not neglect vines, shrubs, and 

 flowers. Your space for trees may be limited, but you 

 can always find corners, fences, and walls for vines, 

 shrubs, and flowers, and it is generally easier to make
