| Lumber |
The
chair you are sitting on was perhaps once part of a tree that grew in a forest.
Lumber,
as we know, is the wood of trees that has been sawed into planks, boards, etc.
Before
tree can be sawed into lumber, it must be cut down and transported to the
sawmill.
The
logs are sent through the sawmill on a moving belt. When a log first enters the sawmill, jets of
water give it a stinging bath to remove the sand and dirt that might dull the
teeth of the saw.
After
washing, the log is then rolled onto a carriage that carries it into the teeth
of the head saw that saws it into rough boards.
When
the log has been reduced to boards, the boards travel to other saws that trim
off the rough edges and cut them to the right length.
Then
they are sorted and planed smooth.
Finally, the lumber must be seasoned, or dried, so the woods will not
warp or rot. – Dick Rogers
