"He may have been here for years," I added.
"He may," Torrence replied, and then producing a paper from a large packet, asked me what I thought of the signature.
I started, for I recognized it at once. It was one of those I had seen through the keyhole in the hotel Mustapha, and the signature was the same as the one before me—Ned Merrick. I then recalled the fact that I had heard my brother address the mysterious stranger—I mean the sailor we had first met upon the Thames boat, and whom afterward I had seen at the Mustapha—as Merrick. Could it be possible that he was the same who had escaped through the ice belt to this island? I was amazed, but before I could make an inquiry Torrence continued:
"I now am certain that this island is inhabited, as I told you, unless, perchance, the man has died. I am also sure of the continents; for the man Merrick having told me the truth in this most amazing case, it is probable that he has not lied in other matters, especially as he gave me proof, and as his story coincides with my own views. Let us look for Jan von Broekhuysen, then we will proceed upon our voyage."
We made a careful search for this extraordinary individual, but not finding any traces of him, we returned to the vessel and prepared to go.
As we were clearing the coast a creature of scarcely human aspect, clad in a robe of feathers and covered to the waist with a mass of tawny gray hair, appeared to rise out of the sand. He probably emerged from the shelter of some neighboring rock, and stood for a moment looking at us in amazement. On a motion to alter our course, as if to pursue him, the creature disappeared as suddenly and strangely as he had come. He was simply invisible, and it would have been useless to waste our time in an effort to capture him. There was no doubt to our minds that this was Jan von Broekhuysen.

Northward again we proceeded on our journey, and from the upper deck surveyed the solitude of an ocean unknown to human eyes. All traces of ice had vanished; the sea was tranquil and the air pleasant. Naturally enough our conversation fell upon the mysterious cairn and its contents.
"In my opinion," said Torrence, "this Jan von Broekhuysen is the most unique creation of our planet. He is the only human being of his kind since creation. I will guarantee that not in a million years has the earth produced such another!"
