The guide grinned at Lewis.

"It is a picture of the world," he said. "He stares at it daily."

"Yes," said the stranger, "here we are—Joazeiro."

Lewis leaned over his shoulder. He saw the word "Joazeiro." From it a straight red line ran eastward to the edge of the map.

The stranger measured distances with a pencil. "We can make Joazeiro in fifteen days," he said. "Tell the men we will rest to-day and to-night. To-morrow we start."

The marvels of that camp were a revelation to Lewis. He kept his mouth shut, but his eyes were open. One battered thing after another revealed its mystery to him. He turned to the stranger.

"You are a great traveler," he said.

The stranger started. He had been day-dreaming.

"A great traveler? Yes. I have been a wanderer on all the faces of the earth. I have lived seven lives. I'll give them to you, if you like."

Lewis smiled, puzzled, but somehow pleased.
