There are many ways of building a camp fire, but the Indian's way is the best. The Indians always used to laugh at the white men because they said that they built such a big fire they could not get near it, while the Indian built a little fire and could get close to it. The fire must be built systematically. First, get dry, small dead branches, twigs, fir branches and other inflammable material and place these loosely on the ground, being sure that the air can draw under and upward through the mass. Next place some heavier sticks in the form of a pyramid with the tops of the sticks close together, and so on, until you have built the camp fire to the required size. Take every care to prevent the spreading of the fire, and do not build it too close to the tent or to inflammable pine trees. There is always danger of starting a disastrous forest fire by carelessness with a small camp fire. Remember that it is criminal to leave a burning fire, and always to put the fire out with water or earth. If the fire is to be used for cooking, it is well to confine the heat between two large logs, or, if baking is to be done on it, it is best to build an oven with large stones. But the Indians were usually content with open fire. [Illustration: HOW TO BUILD A FIRE] How to Get Pure Water A very necessary item for the camp is pure water. If this cannot be obtained from a nearby spring which has good, clear water, or from a clean stream, it is possible to filter it in the same way that the Indians did. They had a way of purifying water from a pond or swamp by digging a hole about one foot across and down about six inches below the water level, a few feet from the pond. After it was filled with water they baled it out quickly, repeating the baling process about three times. After the third baling the hole would fill with filtered water. [Illustration: A STONE OVEN] If there is a stream at hand large enough to swim in, it is well to remember that if you work your hands and kick your feet you can stay above water for some time, even with your clothes on. Do not make the mistake of going into the water too soon after eating, for cramps are apt to result, causing a serious accident. The Indians have a method of protecting themselves from cramps. Coming to a bathing pool, the Indian swimmer, before entering the water, vigorously rubs the pit of his stomach with the dry palm of his hand. This rubbing probably takes a minute; then he dashes cold water all over his stomach, and continues the rubbing for another minute; and after that he is ready for his plunge. How to Cook in Camp
