One day Bob took two of his friends into the
mountains. They put up their tents and then rode off to a forest to see how the
trees were growing. In the afternoon when they were about ten
kilometres from their camp, it started to snow. More and more snow fell. Soon
Bob could hardly 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 white snow. 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 kilometres in such cold
weather! It was getting late. They rode on and on. At last the
horses stopped. Where were they None of them could tell. John looked around.
