“In building a campfire, the first thing that should be done is to dig up and clear away all the inflammable material in the vicinity of the bed of the fire. If possible, the fire should be laid on hard soil or rocks. Then a narrow trench toward the wind will furnish a draft. If you notice, I have not much wood on that fire. A lot of wood is not necessary for a hot flame. A small amount placed properly and renewed as required will give a concentrated heat. Never allow the flame to blaze higher than is needed for the cooking. When you have finished and are leaving the vicinity, if only for a couple of hours, be sure that the fire is out. You cannot put a fire out in the woods by throwing dirt on it. Go to the nearest stream and get enough water to thoroughly quench all signs of fire. The water must sink down below the surface in soil like this and extinguish any sparks which may have worked under the surface.”
