14 SHADE TREES. 



when, planted in rich, moist soil, and their slender habit 

 adapts them well to narrow streets, but they are even shorter 

 lived than the maple, are offensive by the litter that they make 

 Trees to i n spring and by the many root suckers that 



nvoid * they produce. For these reasons ihey are ex- 



cluded from the streets of Albany, Is". Y., by a city ordi- 

 nance. In Washington, D. C., the silver maples and poplars 

 planted years ago are being replaced by other species. Wil- 

 lows have no recommendations whatever as street trees. 

 None of these trees, therefore, should be planted unless it 

 be for a momentary effect. Twenty years after planting, any 

 of the trees recommended will be in better form and, if w r ell 

 chosen and properly cared for, almost as large. Black locust 

 should not be planted solely because it is sure to be injured 

 or destroyed by the borer worm. Except for this fault it 

 makes a fine tree for narrow streets on account of its hardi- 

 ness, narrow crown and fine foliage. Beech is a slow grower 

 and casts too dense a shade for any street. It is further 

 objectionable for any public place because its smooth bark 

 tempts every jackknife carver. Walnut and the hickories in- 

 vite injury by their fruit and, therefore, have no place as 

 street trees. Chestnut is sure to fall a prey to the bark 

 disease, see page 101. 



PLANT THE TREE THAT SUITS LOCAL CONDITIONS. 



Any of the trees here recommended will grow in every part 

 of the State but, after meeting other conditions, a careful 

 planter will chose that whose natural habitat is nearest like 

 the planting site. If the soil be very dry chose scarlet oak, 

 hackberry, honey locust rather than white ash, white elm or 

 Norway maple. If it be clay, red gum, pin oak or sycamore 

 A close re- will be apt to do best. By changing the soil 

 between soil natural conditions can often be modified so that 

 and tree. tne p re f erre( J species may be planted. Any soil 

 but the very best should be enriched when, a tree is planted, 

 for the needs of the tree are apt to be forgotten afterwards.
