"Is that the kind of musician who plays an opportune at every opportunity?" inquired John St. John in a tone of gravity as deep as the cavern in which they were housed.

"Now, see here, Johnnie Two Times," exclaimed Miles portentously: "you know what we came near doing to you six months ago for springing that kind of stuff."

"We came near ducking him in the lake," reminded Earl Hamilton.

"Yes," continued Miles in the attitude of a stage threat, "and if we can't find a lake around here we can find a deep snowdrift to throw him into."

"I wonder if he catches the drift of that argument," said Clifford Long, with a wink at Miles.

"He not only catches it, but he understands, and hence he does snow drift (does know drift) of what the menacing Miles means," declared John, who had long answered to the nickname of "Johnnie Two Times," because of the combination of baptismal and family names by which he was legally known.

A roar of pun-protesting groans filled the cavern, and as several of the boys arose in attitudes of vengeance, the punster made a dive for the exit and disappeared beyond the blanket portiere. None of the protestors followed. They did not feel like engaging in any vigorous sport following the strenuous exercises they had had.

Five minutes later "Johnnie Two Times" returned. One glance at his face was sufficient guarantee that he had lost all his punning facetiousness. He held in his hand a bit of paper which he laid on the stone table by the lamp.

"Read that, boys!" he exclaimed, excitedly. "I found it outside. Those men must have dropped it. They're after Mr. Stanlock—going to hold him up."

The ten other boys needed no second bidding. They crowded around so eagerly that nobody could read.
