"Yes," he replied without hesitation. "I've got a real hunch that he's our friend, and I'm not sure of Nalboon. He doesn't act right."

"I think so, too," agreed the girl, and Crane added:

"I can't say that I relish the idea, but since I know that you are a good poker player, Dick, I am willing to follow your hunch. How about you, DuQuesne?"

"Not I," declared that worthy, emphatically. "Nobody wires me up to anything I can't understand, and that machine is too deep for me."

Margaret elected to follow Crane's example, and, impressed by the need for haste evident in the slave's bearing, the four walked up to the machine without further talk. The electrodes were clamped into place quickly and the slave pressed a lever. Instantly the four visitors felt that they had a complete understanding of the languages and customs of both Mardonale, the nation in which they now were, and of Kondal, to which nation the slaves belonged, the only two civilized nations upon Osnome. While the look of amazement at this method of receiving instruction was still upon their faces, the slave—or rather, as they now knew him, Dunark, the Kofedix or Crown Prince of the great nation of Kondal—began to disconnect the wires. He cut out the wires leading to the two girls and to Crane, and was reaching for Seaton's, when there was a blinding flash, a crackling sound, the heavy smoke of burning metal and insulation, and both Dunark and Seaton fell to the floor.

Before Crane could reach them, however, they were upon their feet and the stranger said in his own tongue, now understood by every one but DuQuesne:

"This machine is a mechanical educator, a thing entirely new, in our world at least. Although I have been working on it for a long time, it is still in a very crude form. I did not like to use it in its present state of development, but it was necessary in order to warn you of what Nalboon is going to do to you, and to convince you that the best way of saving your lives would save our lives as well. The machine worked perfectly until something, I don't know what, went wrong. Instead of stopping, as it should have done, at teaching your party to speak our languages, it short-circuited us two completely, so that every convolution in each of our brains has been imprinted upon the brain of the other. It was the sudden formation of all the new convolutions that rendered us unconscious. I can only apologize for the break-down, and assure you that my intentions were of the best."

"You needn't apologize," returned Seaton. "That was a wonderful performance, and we're both gainers, anyway, aren't we? It has taken us all our lives to learn what little we know, and now we each have the benefit of two lifetimes, spent upon different worlds! I must admit, though, that I have a whole lot of knowledge that I don't know how to use."

"I am glad you take it that way," returned the other warmly, "for I am infinitely the better off for the exchange. The knowledge I imparted was nothing, compared to that which I received. But time presses—I must tell you our situation. I am, as you now know, the Kofedix of Kondal. The other thirteen are fedo and fediro, or, as you would say, princes and princesses of the same nation. We were captured by one of Nalboon's raiding parties while upon a hunting trip, being overcome by some new, stupefying gas, so that we could not kill ourselves. As you know, Kondal and Mardonale have been at war for over ten thousand karkamo—something more than six thousand years of your time. The war between us is one of utter extermination. Captives are never exchanged and only once during an ordinary lifetime does one ever escape. Our attendants were killed immediately. We were being taken to furnish sport for Nalboon's party by being fed to one of his captive kolono—animals something like your earthly devilfish—when the escort of battleships was overcome by those four karlono, the animals you saw, and one of them seized Nalboon's plane, in which we were prisoners. You killed the karlon, saving our lives as well as those of Nalboon and his party.
