     If you go into the forest with friends, stay with them. If you get lost, this is what you should do. Sit

down and stay where you are. Don't try to find your friends, let them find you. You can help them to find

you by staying in one place. There is another way to help your friends or other people to find you. You

can shout or whistle three times. Stop. Then shout or whistle three times again.  Any signal given three

times is a call for help. Keep up the shouting or whistling always three times together. When people hear

you, they will know that you are not just making noise for fun. They will let you know that they have heard

your signal. They will give you two shouts or two whistle. When a signal is given twice, it is an answer to

a call for help. If you don't think that you will get help before night comes, try to make a little house with

branches (树枝) and lots of leaves. Make yourself a bed with leaves and grass. When you need some

water, you have to leave your little branch house to look for a stream. Don't just walk away. Pick off small

branches and drop them as you walk in order to find the way back.
