“It would take us longer than thirty minutes to get there, launch the boat, and beat our way upstream to Rabb Island,” Brad objected.

Mr. Holloway nodded in agreement. “Our best bet is to wait here for the Coast Guard launch,” he decided, “even though it’s hard to remain idle.”

Little more was said by the Cubs although their anxiety was far from relieved. Wandering up and down the shore, they repeatedly checked the level of the water. Slowly but steadily, the river was creeping higher.

“Two years ago when the floods came, Rabb Island was almost entirely submerged,” Brad remarked, gazing anxiously at Mr. Holloway. “Do you think there is danger it might be covered again?”

“The river was at least two feet higher then, Brad. There’s no immediate danger of the entire island being flooded.”

“We’re not positive Mr. Hatfield and Chips reached the island, though the signals appeared to come from there,” Mack remarked. “If we interpreted the message right, something happened to the boat.”

“That’s what I can’t figure,” said Dan. “Do you suppose it sprung a leak?”

“Possible, but hardly likely,” the Den Dad replied. “That boat was tight as a drum. I caulked the seams myself.”

“Hey!” Brad suddenly shouted. “I see a light on the river!”

The other Cubs turned to gaze where he pointed. Far across the water they could see a bright, moving light.
