4. Don't build a camp fire any larger than is absolutely necessary.

5. Don't build a fire against a tree, a log, or a stump, or anywhere but
on bare soil.

6. Don't leave a fire until you are sure it is out; if necessary smother
it with earth or water.

7. Don't burn brush or refuse in or near the woods if there is any
chance that the fire may spread beyond your control, or that the wind
may carry sparks where they would start a new fire.

8. Don't be any more careless with fire in the woods than you are with
fire in your own home.

9. Don't be idle when you discover a fire in the woods; if you can't put
it out yourself, get help. Where a forest guard, ranger or state fire
warden can be reached, call him up on the nearest telephone you can
find.

10. Don't forget that human thoughtlessness and negligence are the
causes of more than half of the forest fires in this country, and that
the smallest spark may start a conflagration that will result in loss of
life and destruction of timber and young growth valuable not only for
lumber but for their influence in helping to prevent flood, erosion, and
drought.--U.S. Dept. Agri., Forest Service.
