Soon the boat was resting quietly in the water, on a "level keel," as a sailor would say, and floating slowly along.

"Now we're all right, Sue!" said Bunny. "Stop your yelling! We're not going to sink!"

"How do you know?" she asked. "We bumped into something, and maybe there's a hole, and the water's coming in, and——"

Just then Mr. and Mrs. Brown came running up on deck, followed by Uncle Tad and Captain Ross. The old seaman, with an anxious look around, called to Bunker Blue.

"What happened? Did some one run into us?"

"Felt more as if we ran into something," Bunker answered. "But I didn't see so much as a canoe."

"We struck something under water, of that I'm sure," said Captain Ross. "We'd better take a look. We're near shore, anyhow, and it won't take long to row over if we have to," he added. "But we surely did hit something."

"Maybe it was a whale," suggested Sue.

"Whales don't come up in the bay. They're too big and fat," declared Bunny.

"Well, maybe then it was a shark," the little girl went on. "They're not so fat."
