at that, who was rubbing his elbow furiously, as though it had
been smartly tapped in his fall.

No need to put a label on this fellow to signify what his presence
meant. Frank knew that he was looking on a spy, who had been
perched among the thick branches of that pine tree during the
better part of the afternoon, making notes of the signal play of
the Columbia eleven!

And he was now moving off, possessed of information that was of
tremendous value to the Clifford team!




CHAPTER VI

AT THE SINGING SCHOOL


Frank did not hesitate a minute. He believed that it was his duty,
if possible, to overtake the spy, and not only learn his identity,
but in some fashion make him promise not to reveal what he had
seen and heard.

He started as fast as he could, making allowances for the fact
that he did not wish to alarm the fellow too soon. The shades of
evening were not far away, since night comes early in mid-November,
and try as he would, he found it impossible to decide as to
whether the other was someone he knew or a stranger.
