DECIDUOUS ORNAMENTAL TEEE3. 153 



13 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 halsamiferd), chiefly found in 

 Northern America ; a large tree, 80 feet high, with fragrant 

 gummy buds and lanceolate-oval leaves ; the Balm of 

 Gilead poplar (P. candicans), resembling the foi'egoing 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. grandidentatd), 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 

 3'oung 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. angulata)^
