But Bob stoutly refused.

“We’ll just have to get going again,” he said. “Have to find our dads and the others as soon as we can.”

Joe knew that this was necessary, and so arose without saying anything further.

The boys were obliged to begin the day without any breakfast, although both were ravenously hungry. They saw several small animals dart across their path, but decided to lose no time in shooting them. Delay, they knew, might mean tragedy to them.

They had not the slightest notion of which way to go in search of the safari, but they agreed to strike out to the west, as that was the direction previously taken.

Along toward noon Bob called his chum over to a little clearing.

“Look at that strange track,” he pointed out. “Was that made by a wild animal?”

“Search me,” Joe said. “I never saw anything like it before. Looks like the footprint of a person, only it’s much larger, and there aren’t any toe marks.”

The youths recalled the different animals they had come in contact with and read about. But none, they were sure, could make footprints anything like this.
