"I was quite unprepared to make any searches along the hillside, except for evidences of minerals, and particularly to note the peculiar outcropping of the rock on this side of the ridge which terminates at Observation Hill.
"The backbone of the ridge is limestone, and after I had reached a certain level I noted, all along, that the rock had remarkably wide cleavages; that is where there had been breaks in the rock the seams opened, and in some places I found recesses fully six feet wide, and thus caverns, sometimes thirty or forty feet in length, would be formed.
"I explored some of them in the hope that it would lead me to a cave of some extent, but in this I was disappointed. Such may be the case, but I have not discovered anything which leads me to believe that there are other caves than the one we explored.
"I entered one of those, which was a long way this side of Observation point, and there, on a rude sort of improvised wooden cot, was a skeleton. I found a half dozen arrows, lying near, but neither a bow nor any other kind of weapon was anywhere in sight.
"The skeleton showed that it was the remains of a tall man, past middle age, undoubtedly, and there was no evidence that he came to his death by any wound which effected a fracture of any of his bones. The cot on which the skeleton reposed was made of pieces of wood, in a complete state of decay, and there was not a vestige of clothing, jewelry or pocket articles at or near the bones.
"I found two of the arrows near one hand, and the others lying about. Here they are. Handle them carefully, as they are decayed, and will readily fall to pieces, unless you use the utmost care. That is my story. I hunted all about the vicinity, hoping that I might find some additional clues, but I was disappointed."
"Do you think he had any connection with the skeleton we found on shore?"
"No; it does not seem likely. My reason for saying so is, that it would take several years for wood to decay, as you see in the case of these arrows, and the cot had the heaviest portions all rotted. In my opinion this skeleton shows greater age."
"Under conditions of that kind, what sort of story could you weave out of it, so as to determine what happened to him?"
"It is decidedly more interesting than our adventure, and about as difficult to gather any information from," answered Harry.
