yet this trouble is not so serious as to prevent its use for anv situa- 

 tion where shade trees can be grown. It loves good soil, but will 

 adapt itself to poor fare if necessary. 



The horse chestnvit {Aesculus Hippocasfanum) is a tree from 

 Europe. It grows very freely, gives dense shade, and is a popular 

 favorite on account of the beauty of its flowers in the early summer. 

 Its foliage ripens and falls early in the autumn. It is a suitable 

 tree for city streets but must have a strong soil. 



The soft maple (Acer dasycarpum) is a fine tree for wide streets 

 or waysides where good soil is abundant. It requires space and 

 sunlight to give the best results. It is reputed to be easily injured 

 by storms on account of weakness of fibre; this occurs only when 

 it is grown under crowded conditions. 



The hard or sugar maple {Acer sarrharinum) does not make a 

 good city tree; it is impatient under rough treatment; sidewalks 

 and paved streets are fatal to it. It is, however, a good tree for 

 suburban conditions, or for country waysides. This tree will 

 adapt itself to a thin soil and is one of our handsomest North 

 American trees. 



The Norway maple {Acer platanoides) is an introduction from 

 central Europe. It forms a rather wi<ie-spreading, handsome top, 

 with a wealth of large leaves, and gives a dense shade. It is not to 

 be recommended for city conditions qn account of its width of spread; 

 it is suitable only for wide streets and waysides. When young its 

 foliage is thin and tender, and, in exposed positions, it is easily 

 damaged by storms. 



The American ash {Fraxinus Americana) is an adaptable tree. 

 It grows fairly well in suburban districts as a sidewalk tree, but is 

 not so desirable as many others on account of the late leafing out 

 and early ripening of its foliage. In poor soil and in dry localities 

 it is apt to be attacked by borers and by the scale insect. In rich 

 soil its growth is rapid, producing a picturesque tree. 



The buttonwood, or sycamore {Platanus occidenialis), is a lofty, 

 quick-growing tree, but is not to be recommended for planting in 

 this section of the country, on account of its liability to infestations 

 of fungi, which blacken the leaves. Its near relation, the oriental 

 sycamore, resembles it in appearance, although it is more compact. 

 This species is much valued in New York and its neighborhood for
