164 Landscape Gardening 



like the tulip tree, difficult to transplant. It is a little more 

 spreading than the tulip tree, beautiful in bloom, and also 

 in fruit. 



Many other species of trees might be used for street or 

 avenue decoration under some conditions, but the above list 

 includes the best for general purposes. Scarcely one-tenth 

 of our roadways, and probably much less, are adorned with 

 ornamental trees; even in many of the thriving towns and 

 cities little attention is given to this matter, and the author 

 would urge the use of more variety of species and less of 

 the stereotyped kinds, like the elm and maple. 



Upright or Round-headed Trees 



The following list, while not including all the trees desir- 

 able under varying conditions, yet contains the greater 

 number of the most beautiful and especially those that will 

 most certainly thrive under ordinary care. Many of the 

 very new or rare varieties are not included for the reason 

 that little is known of their real value, and it is almost the 

 universal experience that a large percentage of the new 

 introductions fail to realize the promise of their early growth, 

 soon developing some weakness, disease, or other undesirable 

 features, and their value cannot be determined until they 

 have been tested for many years under various conditions 

 of soil and exposure.
