height. Taking them as they come, Mr. Lewis has succeeded in 

 spraying them once at the low cost of about 15 cents per tree. 

 This is largely due to the excellent apparatus, to be described 

 later, and is a most encouraging feature of the work. 



"It is hoped that these figures will induce private individuals 

 to provide protection for their trees, either by doing the spraying 

 themselves or else by hiring some capable party." 



We are informed by Mr. Wirth, Park Superintendent of 

 Hartford, that the cost of spraying in Bushnell Park last sum- 

 mer averaged Si.oo per tree and that the benefit to the trees 

 was well worth the outlay.* 



VARIETIES OF TREES SUITABLE FOR STREET PLANTING. 



In conclusion, we desire to say a few words regarding the 

 kinds of trees which it is desirable to plant on city streets. 



New Haven, the "Elm City," has for many years been noted 

 for the beauty of its elms, and it seems eminently proper that 

 this character should be preserved. It is, therefore, recom- 

 mended that when the old elms die, they be replaced by the 

 same species. If the newly set trees are properly cared for, 

 there should be no difficulty in producing specimens of as fine 

 proportions as those now standing. 



Next to the elm, the most popular tree for street planting 

 in New Haven has been the sugar maple. In youth it forms a 

 compact, oval, or egg-shaped crown of remarkable symmetry. 

 With advancing age the top becomes broad and often nearly 

 flat, giving the tree an expression of dignity, which it altogether 

 lacks when young. It is transplanted with ease and thrives 

 well in the unfavorable conditions of large cities. It grows 

 rapidly, being surpassed in this respect among the maples only 

 by the silver variety. 



The red maple seems to thrive admirably in New Haven. 

 Although it is surpassed by the other maples in grace of form, 

 it will always be a favorite street tree on account of its scarlet 

 flowers, which appear early in spring, and its brilliant autumn 

 foliage. It is recommended for planting in New Haven. 



The silver maple has been planted in the New Haven streets 

 only to a limited extent. In its natural habitat it is one of the

 of appointment and duties of a city Forester and regarding the estab- 

 lishment of a city nursery are" chiefly of local interest and need not
