"We shall probably have to explore in order to find traces of our inhabitant; and I wonder, therefore, if it would not be wiser to sail around the island before disembarking. It would certainly save trouble."

We concluded therefore to take a leisurely tour of discovery, and ascertain the size and general contour before landing; and so without further ado, we rose again, almost as soon as we had touched the ground.

The island was rocky, but not without vegetation, its arable parts being carpeted with vivid green. There was also a quantity of small trees, bearing a peculiar fruit, which neither of us had ever seen before. Inland, it rose into billowy hillocks, to probably an elevation of a couple of hundred feet, near the center. Its shores were indented with a number of bays or inlets, some of which made considerable inroad upon it. To the best of our judgment it was about four miles long, and of very irregular width, as in places these inlets nearly cut it in two. Thousands of pigeons flew out wherever we approached their rocky nestings, but there appeared to be no other animal life.

"And where is your inhabitant?" I asked, when we had gone around the greater part of the coast.

"We may not be able to find him at all," he answered; "I said we should probably discover traces of him if we searched. For my part, I have not given that up."

But the words were scarcely spoken when he sprang to the governing board and halted the vessel. I saw that we were hovering over a green sward which sloped gently to the water's edge near the head of one of the inlets described. Lowering ourselves gradually we landed on a grassy knoll, and Torrence immediately threw out the ladder and went over. I followed him, and in a minute saw what had attracted his attention from above, but which had entirely escaped mine. It was a rough looking stone, set on end, in the sward, and there being no other stones in the vicinity, it presented rather a peculiar appearance, inasmuch as it seemed almost certain that it had been placed there by human hands. We examined it with growing interest. There was something uncanny in finding such an object in such a place. It looked like a monument intended to mark a tomb, or the headstone of a grave in some country churchyard. It was about three feet high, nearly covered with a green mould, and had the appearance of great age.

"This," said Torrence, "is the first indication I have found!"

He was passing his hand over the face of the stone.

"Your single inhabitant must be a giant to plant such a rock as that!" I observed.

"Not at all," said Torrence; "I have no idea that he even touched it."
