stream was widening out now, and Betty remarked:
"We'll soon be in the lake now."
"The boat—not us, I hope," murmured Grace.
"Of course," assented Betty. "Won't you stay with us to-night, Uncle Amos?" she asked, as she opened the throttle a little wider, to get more speed. "You can have one of the rear—I mean after, bunks," she corrected, quickly.
"That's better," and he smiled. "No, I'll berth ashore, I guess. I've got to get back to town, anyhow. I just wanted to see how you girls were getting along."
The Gem was speeding up. They rounded a turn, and then the girls exclaimed:
"Rainbow Lake!"
In all its beauty this wide sheet of water lay before them. It was dotted with many pleasure craft, for vacation life was pulsing and throbbing in its summer heydey now. As the Gem came out on the broad expanse a natty little motor boat, long and slender, evidently built for speed, came racing straight toward the craft of the girls.
"Gracious, I hope we haven't violated any rules," murmured Betty, as she slowed down, for she caught a motion that indicated that the two young men in the boat wished to speak to her.
