“Who are the others?” asked Dick.

“I don’t know,” replied Ben. “They were husky-looking fellows who claimed to be mounted policemen. One of them killed the bear.”

“Those are the fellows!” Dick exclaimed.

“You’ve seen them, have you?”

“Not to-day,” Dick replied. “Yesterday, two men answering the description came to our camp and asked all sorts of questions about the object of our visit. They asked where we came from, and how long we were going to stay, and if we had seen other strangers in the mountains.”

“Did they claim to belong to the mounted police?”

“They did not, but they appeared so everlastingly curious to know all about us that somehow I got the idea that they did belong to the Canadian force. They were hungry when they came to our camp, too.”

“Did they say anything about aeroplanes?” asked Ben.

“Not a word!” was the reply.

“And, look here,” Dick observed, cutting an extra large piece of steak from the slice which lay on his plate, “I think I saw the camp-fire of our visitors to-night. It’s up on the slope to the north.”
