 broad one. In order to cover it m a way that I think would 

 appeal to you I have attempted to classify them according to 

 their special purposes. I shall use so far as I can, the common 

 names and the lists will be arranged accordmg to the various 

 uses to which the trees or shrubs should be placed. 



I will first speak of trees for Street Shade Purposes : 



Perhaps the finest tree that we can consider as a street shade 

 tree is the American elm. It has its limitations as its rcots are 

 troublesome and in narrow streets it spreads out too broadly 

 and the shade is a little denser than we would like but no trees 

 allow so free circulation of air. The English elm is next though 

 not so well adapted for street planting for American conditions. 

 The English elm holds its foliage longer, is slower in growth 

 and less desirable. 



Another tree of first importance is the ash. With the possi- 

 ble exception of the elm no tree seems so well adapted to street 

 planting as the American ash. The trunk of this tree must 

 be protected from harm ; it is free from attractions that draw 

 children. 



In the city the Ailanthus has a great advantage as it will 

 grow in less soil than most any other tree. 



The honey locust is seldom thought of for street planting but
