“What’s she going off in that direction for?” asked Dick. “Did you notice that she came from the camp I mentioned a short time ago?”

“I did notice that,” answered Ben, “and I’m wondering why.”

The Louise swept along at amazing speed and was soon lost to sight behind the summit to the west. Ben arose and entered the tent where Mr. Havens lay.

“You saw the Louise?” the boy asked.

“Are you sure that was the Louise?”

“There’s no doubt of it,” Ben replied. “The ordinary aeroplane doesn’t carry a light like that. It’s the Louise, all right, and I was wondering what the boys are going toward the coast for.”

“I wish I knew that the boys are in charge of her,” Mr. Havens said, after a moment’s thought. “I’m always afraid something will happen when those boys get off together. If I hadn’t walked all over those porcupines last night, I’d mount the Ann and make an investigation.”

“If you think it’s safe for you to remain here with these visitors,” Ben suggested, “I’ll go up in one of the machines and see what they’re doing. I’m rather nervous over the matter myself.”

“I heard the talk going on by the fire,” the aviator explained, “and my impression is that these men are all right. Still, it’s rather a risky thing to do, to leave the camp and one machine in the custody of a man incapable of defending them.”

“Perhaps we’d better wait a short time and see if the Louise doesn’t return. I don’t like to take chances,” added Ben.
