“Freezing is right,” repeated Jack, as he too began to swing his arms. “It’s cold enough to freeze the hair off a bald man’s head.”
“Sis-s-h,” Bob cautioned. “It’s so dark that fellow might be within a few feet of us without us seeing him, and if he hears us talking we’ll likely have this job to do all over again.”
For some minutes after that no one spoke. They kept moving about but did not separate more than a few feet from each other.
“It’s about time for the concert to begin,” Bob declared as he stepped close to Jack. “It’s five minutes past eleven.”
“I should think——” Jack began, but stopped suddenly as a low sighing sound as if the wind was rustling the leaves of the trees came to their ears.
“Listen, I guess it’s begun,” Bob declared as he turned his head slightly.
Rapidly the sound increased in volume and in pitch, and in spite of himself a shudder ran through his body.
“He’s a peach all right, whoever he is,” Jack whispered.
“Sure an’ he’s right over to the right of us an’ not mor’n three hundred fate away,” Tom declared as the cry ceased. “Follow me now and make it aisy,” he ordered as he swung off to the right, closely followed by the two boys.
They had gone but a few feet when the cry began again, and now it was considerable nearer.
