“There may be smallpox there,” said Dr. Brady. “I’d better go over there.”

Leaving Sandy and Toma behind to watch the camp during their absence, Dr. Brady and Dick went forward to investigate. They were received warmly at the first tepee, and were informed that no one was ill. In fact, the Indians had not even heard of the epidemic. At each of the tepees in turn they were received graciously until they came to the fourth and last.

Here their reception was very cool indeed. The place was occupied by an aged Indian couple and by a young man, evidently their son. This young man became very angry upon their entrance. He sat opposite the entrance, blankets wrapped around him, and scowled continuously. When Dick questioned him, he refused to answer, pretending that he did not understand. The old Indian squaw seemed to be the only one equipped with vocal powers. Over and over, she kept repeating the words in English:

“Go ’way! Go ’way!”

“Don’t seem to be very popular here,” grinned Dr. Brady. “Well, there’s no use of staying very long. I’ll vaccinate them as quickly as I can and then we’ll be on our way.”

Yet when Dr. Brady opened his medicine case and attempted to vaccinate them, they repulsed him stoutly. They were afraid of the doctor. His instruments frightened them. It was evident that they believed that his ministrations were for no other purpose than to subject them to some new and mysterious torture. Finally, the young Indian rose threateningly and commanded them to depart.

As he did so, Dick drew back in surprise. The Indian wore boots, heavy top-boots—the service boots of the Royal Mounted Police—and, what was even more astonishing, a service revolver in its holster at his side. For a full moment he stared at the tell-tale articles, scarcely believing his eyes. Where had the Indian secured these things? Certainly not from the police—unless they had been taken by force or stolen. Dick’s arm trembled as he took Dr. Brady’s arm and pulled him toward the entrance.

“Come on, doctor, we’d better get out of here. It’s no use.”

Outside the tepee, he turned quickly upon his companion:

“I say, doctor, did you notice what that young Indian wore?”
