Uncle Ben fastened the last knot of the rope by which he was tying the rowboats to the launch. Then he glanced quickly up at Lola.

“What’s that you said?” he asked.

“I said a big, white bird is trying to take Trouble away,” answered Lola.

“Well, why don’t some of you older ones drive it away?” asked Uncle Ben, hardly thinking of what he was saying. “Are you afraid of a bird?” he asked.

“Oh, it’s a terrible big bird!” exclaimed Lola, spreading out her arms like wings. “It’s awful big, Uncle Ben!”

“Is it an eagle?” asked the sailor. “No, it can’t be that, either. I never heard of a white eagle,” he said.

“I don’t know what it is,” said Lola. “But please hurry, Uncle Ben. Tom and Ted aren’t there, and Jan is trying to make the big white bird let go of Trouble, only it won’t let go.”

“It must be a big white owl!” exclaimed Uncle Ben, as he started to run, for he now heard the cries of Jan and the screams of Baby William. “I’ve heard of big white owls hurting people, but I thought owls only flew around at night. They can’t see very well in daylight.”

“Oh, it isn’t an owl!” exclaimed Lola, who was running as fast as she could to keep up with Uncle Ben. “I’ve seen owls, and they have big eyes. This bird has big wings and a big, long neck, and it swims in the lake.”

“Then it isn’t an owl! Owls don’t swim, I’m sure of that!” said Uncle Ben.
