We hurried on, and as the sounds of the fiddle became more distinct, the full moon rose from behind a dark mass which proved to be a ruined wall of the building; and immediately afterwards, directly in front of us, we discovered Mike Laffan seated on one of the time-worn and rickety beams which had once formed part of the fort.  There he was, bow in hand, fiddling with might and main; while below him were a whole pack of wolves, their mouths open, singing an inharmonious chorus to his music. So entranced were they, that the brutes actually did not discover us; nor, so far as we could see, were they making any attempt to reach Mike.
