roads, getting machinery out of the mud, and other purposes. A buyer might be found for the wood
at any time. Stored logs or cordwood should be stacked so as to be off the ground and well venti-
lated. This makes it easier to remove them later and delays damage from rot and borers. Cordwood
is usually stacked in easily measured units.
Personnel. If possible, experienced loggers should be employed for lumbering. They will be
able to do it much more efficiently than equally energetic and resourceful persons not used to the
work. The difference may be as much as 10 to 1.
STUMPS
A stump is the base of a tree trunk and its attached root system. The trunk part may be anywhere
from a few inches to many feet in diameter. It usually flares out near ground level into root but-
tresses, which connect it to the major roots. Its top may be flush with the ground or several feet high.
Roots form a network near the ground surface. A few species of trees have a taproot, a strong
root that extends more or less straight down from the center of the trunk. It makes stump removal
much more difficult.
