If Cadet Corporal Murray had any doubts about the necessity for putting this very dirty scheme into practice, or if his not over squeamish conscience was the least bit troubled by the prospect, something happened that same evening which effectually squelched such ideas. It was after supper, during half an hour of so-called "rest," which is allowed to the over-drilled plebe. Mr. Murray, in whose manly breast still burned a fire of rage at the insult which "B. J." Dewey had offered him, resolved in his secret heart that that same insult must and should be avenged. That evening he thought an especially favorable time, for Dewey was still an "invalid," as a result of his last B. J. effort.
