DECIDUOUS ORNAMENTAL TREES.

is so well adapted to confined situations, as its branches 
require less lateral room than those of almost any other 
large deciduous tree. 
It is an objection to some of the poplars, that in any 
cultivated soil they produce an abundance of suckers. 
For this reason they should be planted only in grass ground, 
or in situations where the soil will not be disturbed, or 
where the suckers will not be injurious. Indeed, we con- 
ceive them to be chiefly worthy of introduction in grounds 
of large extent, to give variety to plantations of other and 
more valuable trees. They grow well in almost every soil, 
moist or dry, and some species prefer quite wet and springy 
places. 
The chief American poplars are the Tachamahaca or 
Balsam poplar ( Populus balsamifera), chiefly found in 
Northern America ; a large tree, SO feet high, with fragrant 
gummy buds and lanceolate-oval leaves ; the Balm of 
Gilead poplar (P. candicans), resembling the foregoing in 
its buds, but with very large, broad, heart-shaped foliage. 
From these a gum is sometimes collected, and used medi- 
cinally for the cure of scurvy. The American aspen (P. 
tremuloides) , about 30 feet high, a common tree with very 
tremulous leaves and greenish bark ; the large American 
aspen (P. grandidentata ) , 40 feet high, with large leaves 
bordered with coarse teeth or denticulations ; the Cotton 
tree (P. argentea), 60 or 70 feet, with leaves downy in a 
young state ; the American Black poplar of smaller size, 
having the young shoots covered with short hair; the 
Cottonwood (P. Canadensis ), found chiefly in the western 
part of this state, a fine tree, with smooth, unequally-toothed, 
wide cordate leaves ; and the Carolina poplar (P. angulatd) %
