"What say, boys; it must have been about there, eh?" the one addressed remarked, appealing to his comrades for their opinions.

"Just about," Elephant answered; while Nat nodded his head as the easiest way to cut a Gordian knot.

"Oh! well, he couldn't see anything worth while from here," Frank went on. "Now, did any of you notice whether he used his eyes to look around; or was he only bent on saying howdyedo to you?"

"When Larry grabbed him by the arm and started to lead him out, I saw the gentleman take a good look all around; and that's the truth, Frank," Elephant remarked.

Frank hardly knew what to think. This might be a very significant thing; and then again, if one looked at it another way, was it not simply what any curious stranger, interested in the doings of the venturesome Bird boys, might have done?

It was about ten o'clock, and growing quite hot, since the time was July. Just as Andy had hinted, that bank of dark clouds hanging low along the horizon in the southwest might take a notion to climb up in the heavens at any time, and bring about a summer thunderstorm.

Apparently Frank did not bother his head in connection with such a possibility; for a little later he wheeled his bicycle out of the shed as though intending to leave the others temporarily.

"Be back in half an hour or so, Andy," he called over his shoulder, as his cousin came to the door to see what he was about to do.

"Going over home for something, Frank?" called Andy; but if the other heard he chose or some reason to decline to commit himself.

Had Andy been able to follow his course after he left the field he would soon have known that Frank was rather heading for town than intending to pedal in the direction of his own house, which was situated on the outskirts of Bloomsbury.
