SUCCESS in tree planting on town and city streets depends upon 

 three main factors proper conditions for growth, timely and 

 intelligent care, and selection of proper varieties. The need of trees 

 on city streets and their care are discussed in another bulletin; 1 in 

 this are indicated the kinds of trees suited to different types of streets 

 and to different regions. 



KINDS OF TREES SUITABLE FOR STREETS. 



QUALITIES NECESSARY. 



A tree must be adapted to the climate and to .the soil on which it is 

 to be grown. For use under city conditions it must have healthy 

 foliage that withstands dust and smoke and a root system not easily 

 affected by unusual soil conditions, by restricted feeding areas, or by 

 root pruning when street improvements are made. The top should 

 be in proportion to the width of the street upon which it is used, and 

 it should be rather high headed or easily trained to that form and 

 of open growth. 



Of only a little less importance is the character of the foliage 

 masses, whether dark or light, heavy and somber or open and airy, 

 and also whether they have vivid autumn colorings. Only in the
