Upon examining further, a silver-mounted revolver was found beneath the body.  It was untarnished, and seemingly as good as the day it was completed.  When Mickey came to look at it more closely, he found that only one barrel had been discharged, all the others being loaded.

This fact aroused a suspicion, and, looking again at the head, a round hole, such as would have been made only by a bullet, was found in the very centre of the forehead.  There could be but little doubt, then, that this man, whoever he was, had wandered about the cavern until famished, and, despairing of any escape, had deliberately sent himself out of the world by means of the weapon at his command.  But who was he?

Laying the handsome pistol aside, Mickey continued the search, anxious to find something that would throw light upon the history of the man.  It was probable that he had a rifle—­but it was not to be found, and, perhaps, had vanished, as had that of Fred Munson.  It was more likely that something would be found in his pockets that would throw some light upon the question; and the Irishman, having undertaken the job, went through it to the end.

It was not the pleasantest occupation in the world to ransack the clothing of a skeleton, and he who was doing it could not help reflecting as he did so that it looked very much like a desecration and a robbing of the dead.  To his great disappointment, however, he failed to discover anything which would give the slightest clue.  It looked as if the man had purposely destroyed all such articles before destroying himself, and, after a thorough search, Mickey was compelled to give up the hunt.

Five chambers of the revolver, as has be said, were still loaded, and, after replacing the caps, the new owner was confident they were good for that number of shots.

“Here,” said he, handing the weapon to the boy; “your rifle is gone, and you may as well take charge of this.  It may come as handy as a shillelah in a scrimmage, so ye does hold on to the same.”

Fred took it rather gingerly, for he did not fancy the idea of going off with property taken from a dead man, but he suffered his friend to pursuade him, and the arrangement was made.

In the belief that there might be others somewhere around, Mickey spent an hour or two longer in an exploration of the cave, with the single purpose of looking for bodies.  They approached the ravine in which Fred had dropped his gun.  The Irishman leaped across, torch in hand, and prosecuted his search along that side; but they were compelled to give over after a time and conclude that only a single individual had preceded them in the cave.

“Where he came from must iver remain a mystery,” said Mickey.  “He hasn’t been the kind of chaps you find in this part of the world; but whoever he was, it must have been his luck to drop through the skylight, just as we did.  He must have found the wood here and kindled a fire.  Then he wint tramping round, looking for some place to find his way out, and kept it up till he made up his mind it was no use Then he acted like a gintleman who prefarred to be shot to starving, and, finding nobody around to ’tend to the business, done it himself.”
