e straightened, close against the bars, and began again to fumble with the leather thong which held him prisoner. In his brain was the hazy idea that he might after all make a break for it, and carry Ellen away to a place of safety, taking a chance on finding his way back here to force Barter to operate again and restore him to his proper place. But would not Ellen die of fright at being borne away through the jungle in the arms of an ape? Was there any possibility of forcing Barter to perform the operation? No, for under the anesthetic again, Barter, angered by the thwarting of whatever purpose actuated him, might do something even worse than he had done—if that were possible. Again, even if he reached civilisation with Ellen, every human hand would be turned against him. Rifles would hurl their lead into him. Hunters would pursue him....

No, it was impossible.

Bentley, Ellen, and the Apeman—his own body, ape-brained—were but pawns in the hands of Barter. Barter might be actuated by a desire to serve science, that science which was alike his tool and his god. Bentley scarcely doubted that Barter believed himself specially ordained to do this thing, in the name of science; probably, unquestionably, felt himself entirely justified.

Plainly, now that Bentley recalled things Barter had said, Barter had waited for an opportunity of this kind—had waited for someone to be tossed into his net—and Ellen and Lee, flotsam of the sea, had come in answer to the prayer for whose answer Barter had waited.

It was horrible, yet there was nothing they could do—at least, to free themselves—until it pleased Barter to take the step. It came then to Bentley how precious to them both was the life of Caleb Barter. He could restore Bentley or destroy him—and with him the woman who loved him.

Suppose, came Bentley's sudden thought, Barter should think of performing a like operation on Ellen—using in the transfer the brain of a female ape? God!...

He prayed that the thought would never come to Barter. He was afraid to dwell upon it lest Barter read his thought. He might think of it naturally, as a simple corollary to what he had already done. Bentley then must do something before Barter planned some new madness.
