"'Where do we go from here, boys, where do we go from here?'" sang Roy.

"'Anywhere from Harlem to a Jersey City pier,'" finished Frank, wickedly splashing some drops of water on Grace's immaculate white dress.

"That's sensible, isn't it?" retorted the latter, favoring the offender with a look of cold disdain. "Since we don't happen to be any more than sixty miles from Harlem or Jersey City, I'm sure Allen appreciated your suggestion."

"Oof!" said Frank. "I can't open my mouth without putting my foot in it."

"That's no compliment to your mouth," returned Grace. "Frank, if you don't stop splashing me with that horrid water, I'm going to get out and walk."

"That would be jumping from the frying pan into the fire," returned Frank with a grin, while Mollie, who was in the next canoe, chuckled audibly.

"Goodness," said Betty, as Allen shortened his stroke to bring the canoes abreast. "It's almost impossible to think of there being a war on a night like this. Everything is so calm and peaceful."

"Yes, we haven't even been touched by it yet," said Allen, his mood sobering. "The Englishman to-day was telling us that n.o.body in England began to realize they were at war, until the boys began to come back wounded and disabled."

"Oh, I can't bear to think of it," cried Amy, who, in the canoe with Will, still silent and aloof, had scarcely spoken a word till now.

"It seems as if there ought to be some other way of settling disputes these days."

"That's what every nation thinks, except Germany and her allies,"

returned Frank. "As it is, we've got to fight her as we'd fight a mad dog--wipe the whole German nation off the map, or at least, bring it to its knees."

"That reminds me of something one of the recruiting officers told me the other day," put in Allen, with a whimsical smile. "He said he had talked to hundreds of American enlisted men, and the great majority of them were eager to learn German."

"I don't admire their taste," put in Mollie, with spirit. "I hate the very sound of it."

"Well, the soldier's idea is," explained Allen, "that if he learns the language he'll be able to flirt with the _frauleins_ when he gets to Berlin."

"Again I don't admire their taste," remarked Mollie spitefully.

"Almost all the German girls I've ever seen are too stout to suit me."

"Goodness, I had a German ancestor away back somewhere," remarked Amy anxiously. "Maybe that's why I'm beginning to gain flesh so fast.

You've got me worried."

The boys laughed, but the girls answered rea.s.suringly.

"It isn't your remote German ancestor that's giving you flesh, Amy,"

said Grace condescendingly. "It's eating three hearty meals a day, and the sitting still knitting from morning to night. We girls are used to being on the go all the time."

"What's that you said?" asked Frank, bringing his eyes down from the stars to the lazy figure in the white dress. "I've never seen you when you weren't taking life easy."

"What!" said Grace, sitting up straight, the picture of indignation.

"How about our walking tour--didn't I walk just as far, and as much as the other girls then? And how about swimming?"

"Take it back! take it back!" cried Frank. "If going down on my knees will help any--"

"Don't be a goose," responded Grace shortly, settling herself once more in a comfortable position. "Just a little bit of going down on your knees, and we'll be in the water. Have a chocolate?"

"No, thanks," said Frank absently. His eye had caught a sudden flare of light, that had flickered for a moment and then disappeared.

"Hey, Allen," he yelled. "Did you see that light--over there, to the right?"

"Yes," said Allen, looking puzzled. "And I don't remember ever seeing signs of life over in that direction."

"Isn't that about where the old powder mill stands?" asked Betty, and Allen turned to her quickly.

"Betty," he said, his eyes shining, "you've got it. The government has bought that property, and started the old mill to working. By George, this promises to be interesting."

"There it is again!" cried Frank, while Grace strained her eyes eagerly toward the point. "What do you say to paddling over there and having a look?"

"It's up to the girls," replied Allen, watching Betty's face eagerly.

"What they say goes."

"And they say 'go,'" smiled Betty whimsically. "Do you suppose we'd go back without solving the mystery? Lead on, Macduff--we follow."

So Allen and Frank paddled hard toward the bend in the lake, the other two canoes, which had fallen somewhat behind, quickening the stroke to catch up with them, sensing that something unusual was afoot.

As the canoes in the lead rounded the bend, those in them saw that indeed the old mill had been renovated, but that the flame they had seen had come, not from the old mill, but from a small bonfire started farther in the woods.

And that was not all. What made them catch their breath and signal for silence, was the figure of a man bent close to the flickering fire, intent upon deciphering the writing on a long piece of paper, that looked suspiciously like an official doc.u.ment.

So silent had been their approach that the man had not even changed his position. Luckily the canoes were screened by heavy, overhanging branches of trees, so that the occupants could observe without being observed.

Silently the other two canoes joined them, and noiselessly, scarcely daring to breathe, the young folks watched.

CHAPTER V

A SHOT IN THE DARK

In the minds of each of the young people in the canoes, one word kept repeating itself over and over again: "Spy, spy, spy!"

Since the war had begun, the country had been overrun with them, that they knew; but out here on this remote island... Yet there was something about the very posture of the man, his hunched-up figure, the nervous twitching of the fingers that held the doc.u.ment, that branded him.

As they watched, he started to fold up the paper, glancing stealthily about meanwhile; then, as though satisfied that no one was watching, he picked up the heavy bag that lay beside him, evidently preparing for flight.

Betty, a little tense figure in the bottom of the boat, uttered a gasp of dismay, as Allen began carefully to lower himself into the shallow water.

The man on sh.o.r.e heard the slight sound and turned swiftly, staring suspiciously into the thick shadows of the foliage. Then did the boys and girls literally hold their breath.

After a few seconds, which seemed an eternity to the taut nerves of the watchers, the man turned with a guttural growl, and started cautiously to make off into the denser woodland beyond.

In a second, Allen was out of the boat, and lending a hand to the gallant Little Captain, who would not be outdone in any adventure, no matter how perilous.

The other boys and girls followed, silent as ghosts, their training in woodcraft standing them in good stead. For an instant, they stood in a tense, excited group on sh.o.r.e, Mrs. Irving in their midst.
