44 WORCESTER COUNTY HORTICULTURAL SOCIETY. [1906 



For park and large lawn trees we can use many that cannot be 

 used for street planting. The American ash comes into promi- 

 nence here for the reason that the ash makes so fine a tree in 

 this section of the country. It leaves out late and drops its 

 foliage late. It is a tree that should be used where it comes 

 up naturally. 



The American beech is so well known it is hardly necessary 

 to recommend it. The purple beech is one of the most desira- 

 ble ornamental trees that we have. It is sturdy in growth, de- 

 lightful in foliage effects. 



The catalpa is very desirable for this purpose; the flower 

 effect is good and they are rapid in growth. 



Our American chestnut is best adapted for use in large 

 parks. Few lots are sufficiently large to admit of its use. 

 There is no tree in our native flora that produces so interesting 

 an effect as our American chestnut in its blooming period. 



The honey locust and the black locust are desirable trees be- 

 cause of their adaptability to sterile soil conditions. No other 

 tree, imported or native, that keeps such clean foliage through- 

 out the summer as the black locust. 



In birches Ave have the red birch with its beautiful bark in 

 rich tones of yellow, the canoe birch and the black and white 

 birches which are well adapted for moist conditions. 



The English elm is desirable on account of its late retaining 

 of foliage. The Scotch elm is very desirable because of its 

 round topped foliage. The slippery elm is rarely used. It 

 makes a smaller tree and would be adapted for a small lawn 

 where a large elm cannot be used. 



The black walnut is desirable for its moderate shade effects 

 and makes a fine, open-topped tree. A walnut from Japan has 

 been introduced in late years. 



The aspen and Japanese larch are vigorous and both grow on 

 dry soils, and there is great beauty in these trees. The Amer- 

 ican larch is also desirable. 



Of the maples, the Sycamore maple, Schwerdlers maple, the 

 purple leaf or Norwa}'' maple are all desirable.
