Again it appeared that, quite unintentionally, I had said something excruciatingly funny; for at my speech there arose a sound of gentle laughter from the group, now augmented to quite an assemblage, which drowned the plashing of the waves on the beach at our feet. Even the interpreter smiled.

"Do they think it so amusing to be dumb?" I asked.

"They find it very amusing," replied the interpreter, "that their inability to speak should be regarded by any one as an affliction; for it is by the voluntary disuse of the organs of articulation that they have lost the power of speech, and, as a consequence, the ability even to understand speech."

"But," said I, somewhat puzzled by this statement, "did n't you just tell me that they understood me, though they could not reply, and are they not laughing now at what I just said?"

"It is you they understood, not your words," answered the interpreter. "Our speech now is gibberish to them, as unintelligible in itself as the growling of animals; but they know what we are saying, because they know our thoughts. You must know that these are the islands of the mind-readers."

Such were the circumstances of my introduction to this extraordinary people. The official interpreter being charged by virtue of his office with the first entertainment of shipwrecked members of the talking nations, I became his guest, and passed a number of days under his roof before going out to any considerable extent among the people. My first impression had been the somewhat oppressive one that the power to read the thoughts of others could be possessed only by beings of a superior order to man. It was the first effort of the interpreter to disabuse me of this notion. It appeared from his account that the experience of the mind-readers was a case simply of a slight acceleration, from special causes, of the course of universal human evolution, which in time was destined to lead to the disuse of speech and the substitution of direct mental vision on the part of all races. This rapid evolution of these islanders was accounted for by their peculiar origin and circumstances.

Some three centuries before Christ, one of the Parthian kings of Persia, of the dynasty of the Arsacid, undertook a persecution of the soothsayers and magicians in his realms. These people were credited with supernatural powers by popular prejudice, but in fact were merely persons of special gifts in the way of hypnotizing, mind-reading, thought transference, and such arts, which they exercised for their own gain.

Too much in awe of the soothsayers to do them outright violence, the king resolved to banish them, and to this end put them, with their families, on ships and sent them to Ceylon. When, however, the fleet was in the neighborhood of that island, a great storm scattered it, and one of the ships, after being driven for many days before the tempest, was wrecked upon one of an archipelago of uninhabited islands far to the south, where the survivors settled. Naturally, the posterity of the parents possessed of such peculiar gifts had developed extraordinary psychical powers.

Having set before them the end of evolving a new and advanced order of humanity, they had aided the development of these powers by a rigid system of stirpiculture. The result was that, after a few centuries, mind-reading became so general that language fell into disuse as a means of communicating ideas. For many generations the power of speech still remained voluntary, but gradually the vocal organs had become atrophied, and for several hundred years the power of articulation had been wholly lost. Infants for a few months after birth did, indeed, still emit inarticulate cries, but at an age when in less advanced races these cries began to be articulate, the children of the mind-readers developed the power of direct vision, and ceased to attempt to use the voice.

The fact that the existence of the mind-readers had never been found out by the rest of the world was explained by two considerations. In the first place, the group of islands was small, and occupied a corner of the Indian Ocean quite out of the ordinary track of ships. In the second place, the approach to the islands was rendered so desperately perilous by terrible currents, and the maze of outlying rocks and shoals, that it was next to impossible for any ship to touch their shores save as a wreck. No ship at least had ever done so in the two thousand years since the mind-readers' own arrival, and the Adelaide had made the one hundred and twenty-third such wreck.
