Spruce trees have long furnished the bulk of the woodpulp used in
making our supplies of paper. These trees live in the colder
climates of the northern states. They like to grow in low, wet
localities close to lakes or rivers. The spruces generally do not
grow higher than 75-100 feet. The wood is soft like pine and even
whiter in color. The aboriginal Indians used the roots of the
spruce trees as thread, twine and rope.

The cedar trees, which are landmarks in many of our northern
states, yield light, soft, durable wood that is useful in making
poles, fence posts, lead pencils and cedar chests. The wood of
the red cedar gives off a peculiar odor which is said to keep
moths away from clothes stored in cedar chests, but it is the
close construction of the chest which keeps them out. These trees
are becoming scarce in all parts of the country. Cedars generally
are small trees that grow slowly and live a long time. The
outside wood is white and the heartwood is red or yellow. Cedar
posts last a long time and are excellent for use in farm fences.

Chestnut blight, which destroys entire forests of chestnut
timber, is gradually exhausting our supplies of this wood.
Chestnut timber has long been used for railroad ties, fence posts
and in the manufacture of cheap furniture. The wood is soft and
brown in color. The bark and wood are treated at special plants
in such a way that an extract which is valuable for tanning
leather is obtained. Chestnut trees are upstanding, straight
trees that tower 80 to 100 feet above the ground. The extinction
of our chestnut forests threatens as no effectual control
measures for checking the chestnut blight disease over large
areas has yet been discovered.

The yellow poplar or tulip poplar furnishes timber for the
manufacture of furniture, paper, the interior of railroad cars
and automobiles. The dugouts of the early settlers and Indians
were hewed out of poplar logs. These boats were stronger than
those made of canoe birch. Poplar wood is yellow in color and
soft in texture. The poplar is the largest broad-leaf tree in
this country and the trees are of great size and height. Some
specimens found in the mountains of the South have been over 200
feet high and 8 to 10 feet in diameter, while poplars 125 to 150
feet high are quite common.

Among our most useful and valuable trees are the white oak, and
its close kin, the red oak, which produce a
