with great vigour. In both, the buds of the 
shoots are covered with a profusion of a very- 
fragrant gummy matter. The balsam poplar has 
ovate-acuminate, or oval-lanceolate leaves ; the 
Ontario has them heart-shaped and sharply 
pointed ; in both cases they are saw-edged. 
The balsam poplar is one of the first trees to 
break forth into leaf in the spring, and in 
moist evenings, these and the gummy buds 
are so fragrant as to perfume the surrounding 
air ; those of the other kind are a fortnight 
later. They are chiefly planted as ornamen- 
tal objects. 
We must not omit to mention one peculiar 
situation in which some of the poplars grow 
with tolerable freedom, while few other trees 
will survive. We refer to the smoky atmo- 
sphere of large towns, and especially in popu- 
lated places. In such situations trees are doubt- 
less of much importance in a sanitary point of 
view ; their roots absorb from the soil, and 
derive nourishment from, those very matters 
which pollute the air, and after having served 
the economy of the plant, a portion is again 
returned to the atmosphere in the form of 
pure vital air. For this reason, trees should 
be introduced wherever practicable in densely 
populated districts ; and although alone they 
may not be powerful enough to effect a com- 
plete sanitary reformation, yet, as aids in the 
great social work, they ought not to be over- 
looked. The black Italian, the common black, 
and the Lombardy, are perhaps the best to 
select with this object in view. All the 
species are moreover valuable as screens to 
hide unsightly buildings, or other objects that 
cannot be removed.
