tains. It is also common in the northern part of 
the Mississippi valley. It is, when full grown, a large 
and lofty tree, growing principally in deep, cool soils. 
In some localities it is quite abundant, and, when 
sawed into boards, is much used as a substitute for 
Pine or Tulip Tree wood. The wood is light, soft 
and of little durability, but is nevertheless valuable 
for many purposes. Bees are fond of the flowers, 
and gather from them abundance of honey of the 
very best quality. The bark is also an article of some 
importance. It is peeled from the trees in June, and 
soaked in running water two or three weeks, or till 
the inner part will divide easily into thin layers; the 
outside bark is then taken off, and the inner part laid 
by for use. It is much employed by nurserymen and 
gardeners in budding, grafting and tying up vines 
and small packages. 
The Linden is one of those trees which are not 
valuable for timber until they have attained a con- 
siderable size. Although less deserving extensive 
propagation than several other forest trees, it yet has 
useful properties which recommend it for planting 
to a limited extent. It is often planted for shade, 
and is esteemed for that purpose. It produces seed 
in considerable quantity, which, if sown when ripe, 
or kept in damp sand till spring, will mostly germi- 
nate the first season, The seedlings transplant easily. 
It is also propagated by layers.
