As we all know, jungle country is not friendly to man, but it is possible to sur- vive there. You must have the right equipment and you must know a few important things about woodcraft. No one should go into the jungle without the right equip- ment. You need lightweight clothing, a good knife, and a compass. Fishhooks and a line, a rifle and ammunition, matches in a waterproof container are necessary too. So is a mosquito net.
Keep alert. Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste, and rest often. You will soon become exhausted if you set a fast pace in a hot and humid place. A steady and even pace is wisest in the long run.
Keep calm if you lose your way. Try to decide how long it has been since you were sure of your position. Cut marks on four sides of a tree, so that you will be able to see them from any direction. Except in an emergency, never try to travel through the jungle at night.
wear shorts in the jungle. Your trousers must be lightweight and long. The cuffs should be tucked into your boot tops.
Finding water that is safe to drink can be a problem. Many clear and fresh-look- ing streams and rivers carry deadly germs. Such water must always be boiled before you drink it. Luckily, the jungle has many kinds of plants and vines that give water. Water from almost all plants is pure enough to drink. But stay away from vines that have bitter or milky sap.
Many jungle plants also provide food. Before you go into the jungle, learn to recognize the varieties of plants that can be eaten. If you haven't had a chance to do this, watch what kinds of fruit and nut the birds and monkeys choose.
Such food is almost always safe for man. When you see an animal in the jungle, you can be sure that the source of food is somewhere close by. That source may mean for you a difference between going to sleep well-fed or hungry.
Surviving ha the jungle is a science. The jungle people have become perfect in this science, and you can too. Leam as much as you can about what to expect in the jungle. Make sure you have the right equipment. Then no part of the jungle will seem unfriendly or frightening. In fact, you will be able to "live off" it for a long time.
