in early springtime when the clusters of buds burst into red 

 blossoms. During the summer the bright green foliage 

 makes a pleasing appearance but in early autumn the tree 

 is fairly ablaze with its scarlet and orange foliage. In favor- 

 able soils the tree makes a luxuriant growth and produces a 

 dense covering of foliage. The Eed Maple is fairly free 

 from insect attack. The adverse conditions for tree growth 

 found along most streets and roadways are such as to pro- 

 hibit as long life for the Red Maple under these conditions 

 as in meadows and along streams where many fine old trees 

 may be found. 



13. GINGKO (Gingfco biloba). 



This interesting tree, sometimes called the Maidenhair 

 Tree, is in a way an ideal shade tree. In many parts of New 

 York fairly large specimens may be found. Washington has 

 a fine avenue of them. Although the Gingko grows slowly 

 in any kind of soil, the rate of growth does not seem to be 

 decreased materially by poor soil. This tree when pruned 

 properly and grown well, makes a very ornamental shade 

 tree. It does not cast as dense shade as many other trees 

 until it reaches very large size. The Gingko is absolutely 

 free from insect attack and tree disease. The general tend- 

 ency of the tree is to form a rather pyramidal head and with 

 a few branches that shoot out from the 'main contour of the 

 tree. The Gingko responds well to intelligent pruning and 

 any desirable shape may be formed by training. The 

 Gingko is a very long-lived tree and should be used more 

 commonly. 



14. HACKBERBY (Celtis' occidentals). 



The Hackberry is a native tree that will grow well in 

 almost any soil in the State. The foliage of this tree re- 

 sembles that of the elm. It is a rather sightly tree, produces 

 good shade, and is free from very serious diseases. The 

 tree is often used in the middle west in preference to the elm. 

 It produces a straight main stem that branches high above 

 the ground. The Hackberry, with its interesting warty 

 bark, grows slowly but is vigorous and long-lived.
