"We can see it pretty well from here," said Rose. "And see the islands. There is a lighthouse, Russ. Would you like to live in a lighthouse?"

"Yes, I would, for a while," agreed her brother. "But I'd rather be right on this boat, sailing out into the ocean. Just think, Rose! We've never been away out at sea before."

"There was lots of ocean at Captain Ben's," said the girl. "I suppose the ocean is all the same everywhere. Just water. I hope it stays flat."

"Stays flat?" repeated Russ, opening his eyes very wide.

"Yes," said Rose gravely. "I don't like water when it's bumpy. It makes me feel funny in my stomach when it's that way."

"Oh! It won't be rough," said Russ, with much assurance. "I heard Daddy say we were going to sail into summer seas. And that must be warm and pleasant water. Don't you think so?"

Rose was looking over the rail now. She pointed.

"That doesn't look as though the water was warm," she cried. "See the lumps of ice, Russ? It must be ice water. Where do you suppose the summer seas are?"

"We are going to them," declared her brother with confidence. "Daddy said so. He said we would go out to a place he called the Gulf Stream and that the water would be warm there and the air would be warmer, too."

"What do you think of that?" gasped Rose. "A stream in an ocean? I guess he was joking."
