STREET TREES. oT 
LINDEN. 
The basswood,! or linden, is a large round-headed tree that is 
excellent for roadsides in surburban locations and does well on city 
streets if the conditions are not too severe. On account of the dark 
upper surface and the lighter under surface of the leaves and the 
sweet-scented blossoms in early summer it is much admired. It is 
not as reliable as some of the other shade trees, as when young it is | 
sometimes attacked at the base of the trunk by a fungous growth 
that kills the tree. When once established it forms handsome avenues. 
It is suited to regions 1, 2, 3, 4, 7, 9, 10, and 11. 
The linden,? or European linden, has much smaller leaves than the 
American linden, or basswood, with more contrast between their 
upper and lower surfaces. It is not much different in size, but is 
a little more compact in growth and holds its leaves longer in the 
fall. It is a useful tree for street planting in regions 1, 2, 3, 4, 9, 
10, and 11. 
LOCUST. 
The locust,? or black locust, 1s one of the desirable street trees in 
regions 6, 7, 8, and probably in region 5, as it thrives with com- 
paratively little moisture. It makes a moderate-sized oval head 
that bears sweet-scented white flowers in late spring or early summer. 
Its greatest drawback is its liability to serious injury and disfigure- 
ment by the locust borer,‘ but with proper care this injury can be 
prevented.’ In some parts of the East it is also subject to a leaf 
miner ® that gives its foliage a burned appearance. In region 3 it 
holds its seed pods for several years and thus becomes very un- 
sightly. 
MAGNOLIA. 
The evergreen magnolia’ is one of the few good evergreen trees 
-for street planting, but it is adapted only to regions 1, 2, 3, 11, 12, 
and 13. There are but few conditions that warrant the planting 
of a tree having foliage as thick as this, because of the dense shade, 
which is especially undesirable in winter. It grows to be a large 
oval-headed tree and bears beautiful large white blossoms in late 
spring or early summer. 
MAPLE. 
Among the maples are some undesirable trees much used for 
street planting and some that are valuable only in restricted areas 
or under special conditions. The maples are not as satisfactory for
