GROUP I— TREES FOR STREET PLANTING 



Whether a city is classed as beautiful or not depends to a great extent upon the general appearance of its streets. 

 New England villages have long been noted for their avenues of American Elms. But, in plenty of towns and cities, 

 streets bordered with grass plots and trees are unknown. No better evi- 

 dence of progress and civic pride can be shown than the care exercised over 

 existing street trees and the continued extension of these plantings. Only 

 one variety of tree should be planted in any one block. In fact, it is 

 best to make the planting for several blocks consist of the same variety? 

 of tree. An average distance apart for planting street trees is 4u leeu 

 In cities a strong tree guard should be placed around each newly planted 

 tree to prevent damage by horses and discourage children from swinging 

 on them. 



The following list of trees are especially selected because of their 

 value for street planting. They are all perfectly hardy. Their individual 

 requirements as to soil or location are noted in the detailed description 

 of each variety.
