to excellent advantage as a roadside tree. Mr. John A. Pettigrew, 

 Superintendent of Parks, Boston, speaks highly of the red oak, and 

 states that no better trees can be planted than the red and scarlet 

 oaks. 



The white oak is seldom planted as a street tree, but makes mag- 

 nificent individual specimens for lawns and roadsides. It is occa- 

 sionally affected with a leaf spot fungus (Gloeosporium). 



The honey locust is not native with us, but may occasionally be 

 seen growing along roadsides. City Forester W. F. Gale, of Spring- 

 field, states that he finds it easily broken by winds and susceptible 

 to borers. 



The American chestnut is seldom used for a street tree, although 

 seedlings will make ornamental specimens of fairly rapid growth. 

 They are regarded as dirty trees and are easily broken by winds, 

 and when old require considerable pruning to dispose of the dead 

 wood. 



The Norway maple is a wide, spreading tree, with large leaves 

 which give a dense shade. It is well suited for lawn planting and 

 highly recommended for streets and roadsides. 



The white or silver maple is not equal to the sugar maple, since 

 it is more easily broken down by ice and winds. It grows very rap- 

 idly, and in Connecticut, where magnificent specimens may be occa- 

 sionally seen, it attains a great size. It is planted to some ex- 

 tent on avenues. It is affected by a leaf spot fungus (Rhytisma), 

 which, however, does little harm. 



The red maple branches low and its foliage is inferior to that of 

 the rock maple. During the past four years these trees have rapidly 

 deteriorated in Massachusetts, owing to winter killing, and are dying 

 in large numbers, 



The Ailanthus may be termed a " scavenger tree," as it will grow 

 anywhere and will stand harder conditions than any other tree. It 

 is frequently found growing along railroad embankments, and often 

 grows out of the side of a stone wall and on dumps, etc.; in fact, no 

 conditions seem to be too severe for it. It is little used as a street 

 tree, but excellent individual specimens may be seen here and there. 

 If used as a street tree the fertile form should be selected, owing to 

 the disagreeable odors arising from the sterile trees.
