“Campfires are mighty easy things to start, but unless they are built properly, you can never tell when they are completely extinguished. The bed of pine needles, dried leaves and partially decayed wood in all forests burn very easily, and it is extremely hard to be certain that the fire has not worked its way under the surface. Many times people have left their campfires believing that they were completely extinguished when the entire area was honeycombed with sparks beneath the surface. The campers left their fire thinking that they had done their duty in regard to the rules and regulations concerning forest fires. Shortly after they had gone, the sparks would burn through to the surface and trouble would start for the fire-fighters. Such occurrences are not confined to tenderfeet alone, for some men with years of hunting and camping experience have been guilty of the same neglect.
