hat was Barter doing now? Would he not be striving to watch the course of his experiment? Would he not think of details hitherto overlooked and plan further experiments, or an enlarging of this experiment of which three creatures were the victims? Surely Barter would not remain quietly at Barterville while the subjects of his experiment went deeper into the jungle with the great apes. Barter was too thorough a scientist for that. Somehow, Bentley was sure, Barter would know what was happening, even at this very moment.

He would wish to know how a modern woman would conduct herself if suddenly forced to live among apes. Therefore he would try in some manner to keep watch over the conduct of Ellen Estabrook. He would wonder how a modern man would conduct himself if he suddenly found, himself the leader of that same group of apes, and how an ape would behave if he suddenly discovered himself a man. It was a neat "experiment," and Bentley was beginning to believe that there was probably far more to it than there first had seemed.

Barter would wish to know how all three creatures would conduct themselves in certain circumstances—Apeman, Ellen and Bentley. He would not leave it to chance, for Bentley now realized that Barter himself did not feel inimical to either Ellen, Apeman or Bentley. To him they were merely an experiment. Barter would not wish for Apeman to die, and thus deprive Barter of a certain knowledge relative to one angle of his unholy experiment. He would not wish for Manape-Bentley to remain forever as Manape-Bentley, lacking the power of speech, either human speech or the gibberish of the apes.

No, all this was not being left to chance. Bentley believed that Barter was directing the destination of these three subjects of his, as surely as though he were right with them at this moment, driving them to his will with that awful lash which had made him feared by the great apes.


es, Barter was still the master mind. It made Bentley feel awfully helpless. Yet—he was the leader of the great apes. That, too, Barter must have foreseen. Would Barter try in any way to discover how Bentley would behave in an emergency as leader of the apes? Would he wish to know sufficiently to create an emergency? From Bentley's knowledge of the twisted genius of Caleb Barter, he fully believed that Barter planned yet other angles to his experiment.

If he did, then what would he do next?
