Obediently Frank drew his paddle from the water, and Grace, who had only been making a pretense of doing her share, looked around indignantly.

"Well, you can't expect me to do it all," she said, and with a sigh of utter resignation, Frank resumed his work.

"Say, fellows," he said, "isn't that just like a girl?"

"What's that?" cried Amy suddenly, making them jump nervously.

"What?" queried Grace in a voice scarcely above a whisper, while the rest looked for an explanation from Amy to the shadowy woodland and back again.

"It—it was a noise," explained Amy, incoherently, "like a man moving, and I was sure—I—saw a—couple of eyes watching us—"

"For heaven's sake!" cried Allen, raising himself suddenly in the canoe, "put on more steam, you fellows! We've got to get the girls out of this. What do you say, Mrs. Irving?" turning to their chaperon, who had been a silent spectator until the moment.

"By all means," she said decisively. "We can face these mysteries better by daylight, and we've had enough excitement for one night."

So they all paddled hard while the girls' eyes remained fixed in half-fearful, half-hopeful expectation upon the shadowy shore. For these girls were outdoor girls, and adventure was the breath of life to them.

However, nothing else happened to disturb the calm of a perfect summer night, and a few minutes later they landed at the pier, and hastily fastened the canoes.
