peculiar green foliage in summer. I u ordinary grounds it forms 
only a tree of moderate size ; but in rich strong soils, and near 
water, it makes a large spreading tree. It is not at all suited 
for planting in parks or for bordering avenues or streets, but 
may be sometimes introduced in cemeteries, and especially 
because that it will bear to have its roots and branches cut back 
to any extent almost without appearing to affect its health or 
vigor. 
The white willow — salix alba — has of late years been frequently 
used in some portions of the Western States for forming hedges 
and screens. It is of rapid growth, and when permitted to grow 
by itself, forms quite a large tree. It also may be sparsely intro- 
duced where light and airy groups are desired.
