"I think it's about time we headed for Chicago," Sandy agreed. "When a couple of Boy Scouts who are supposed to be in their right minds climb a tree to get away from bears who are so busy eating stolen fish that they don't know there is a boy within a hundred miles, I think it is about time they headed for civilization."
"What did you mean about the moon rising in the south?" asked Thede.
"Well," Sandy answered, "it looks to me as if there were two moons rising, one in the east and one in the south!"
There certainly was a light growing far up on the hills. In a moment the Indian came back to the boys and pointed out the strange illumination.
"Fire there!" he said.
"What do you think it means?" asked Thede.
"Heap campfire!" was the reply.
Oje held up three fingers to indicate that he saw three fires. His eyes were sharper than those of the boys, who at first saw only a blur of light. Before long, however, they caught sight of three points of flame lifting above the hills. As the boys looked the blazes seemed to die down, or to be obscured by additional material being thrown upon them. As the moon rose, sending a wintry light over the great slope, three gigantic columns of smoke stood where the flames had shown a minute before.
"What do you make of it?" asked Thede.
"Can you read the signal?" asked Sandy.
