One day Bob took
two of his friends into the mountains. They put up their tents(帐篷) and
then rode off to a forest to see how the trees were growing.
In the afternoon,
when they were about ten kilometers away from their camp(营地), it
started to snow. More and more snow fell. Soon Bob could not see his hands
before his face. He could not find the road. Bob knew there were two roads. One
road went to the camp, and the other went to his house. But all was whites now.
Everything was the same. How could he take his friends back to the camp?
Bob had an idea.
The horses! Let the horses take them back! But what would happen if the horses
took the road to his house? That would be a trip of thirty-five kilometers in such
cold weather!
It was getting
late. They rode on and on. At last the horses stopped. Where were they? Bob
looked around. What was that under the tree? It was one of their tents!
