“I’m going to try to get to the cavern ahead of White Nose and Eagle Feather,” he announced with sudden decision. “With luck, I may make it.”

“We’ll go with you,” Dan insisted. “It’s not safe alone.”

Not wasting a minute, the three started off through the woods. They were a considerable distance from camp before they remembered that they had not left a note for Mr. Holloway or Mr. Hatfield to explain their absence.

“We may get back before they show up,” Brad said. “I hope so, but there’s no telling what we may run into. I sure hope we aren’t making a mistake starting off this way.”

In an attempt to take a short route to the cave, Brad chose an inland route. There was no marked trail. Every inch of the distance was a battle against the underbrush. When finally the boys emerged on the beach, not more than a hundred yards from the cave, they were worn from their struggles.

Dan suddenly reached out and jerked Red back into the bushes.

“Down!” he commanded.

Red ducked low and then demanded in a whisper:

“What’s the idea?”

“Look out on the river and you’ll see!”
