“Us?”

“Yes. I insist on going, too, if you start out to look for the Lauriette. And it will look better too. If we are simply paddling about, there being nothing the matter with Chess and Ruth, they won’t be able to laugh at us. Come on!” exclaimed Helen, picking up her sweater. “I am a loyal sister, Tom Cameron.”

“Right-o!” he agreed, more cheerfully. “I suppose there really is nothing the matter. Yet, whatever else Chess Copley is, he’s not the sort of fellow to keep a girl out till midnight on the river when there is nobody else along.”

“Humph! Do you think Ruth is a mere chit of a flapper? You are old-fashioned, Tommy-boy. The day of the chaperon is about over.”

“You know it isn’t over in our set, and never will be,” he returned. “You girls have a lot of freedom, I admit. But there are limits.”

“Baa!” was Helen’s utterly impudent remark.

They ran down to the shore and got out one of the canoes. Helen was familiar with the use of the paddle and served her brother as a good second. They drove the canoe out into the open river, but only just for a look up its expanse.

There was no motor-boat in sight or hearing—not even the distant lights of one. The current was so strong that the Cameron twins went back among the islands where the water was smoother. Besides, it was much more romantic, Helen said wickedly, among the islands, and Chess and Ruth were more likely to remain in the tortuous passages.

The two laid a pretty direct course, however, for the Kingdom of Pipes. As they spied it, and drew nearer, Tom suddenly stopped paddling and held up his hand.

“What’s the matter?” demanded his sister, likewise raising her paddle out of the water.
