 like the Walnut, Butternut and Hickory, are not desir- 

 able along streets. The Black Locust (Robinia pseudo- 

 acacia) suffers so severely from the attacks of the Locust 

 borer and con- 

 sequent decay 

 that it is poor 

 policy to make 

 any but a very 

 limited use of 

 it. The Willow 

 is not adapted 

 either by its 

 form or dura- 

 bility as a street 

 tree. 



I can well

 trees of rapid 

 growth, trees 

 which ordina-

 be used along 

 streets. I have, 

 seen many fac- 

 t o r y streets, 

 railroad grades 

 through cities, 

 and other con- 



ditions where I would not hesitate to use the most 

 rapid-growing tree available, to act both as a screen 

 and to give shade. There are conditions where the 

 necessity for a screen of foliage and for shade takes

 This is difficult to treat, but sycamore or Norway maple, if planted and kept carefully trimmed, would do much to destroy the ugly vista,

A STREET PLANTED WITH WHITE BIRCH 

 Could anything be more inviting, restful, or pleasing to the artistic sense than this tree planting?
