Of course, no one would believe him. This thought kept drumming in his ears. No one—except Professor Osborne. Old Osborne would believe!

George Abbot's mind flashed back to a conversation he had had with the old professor, just before the oil interests had sent him on this exploring trip to discover the source of the large quantities of petroleum which had begun to bubble up from the bottom of a certain section of the Pacific very near where Abbot now was.


sborne had said, "This petroleum suggests a gusher to me. And what causes gushers? Human beings, boring for oil, to satisfy human needs."

"But, Professor," Abbot had objected, "there can't be any human beings at the bottom of the sea!"

"Why not?" Professor Osborne had countered. "Life is supposed to have originated spontaneously in the slime of the ocean depths; therefore that part of the earth has had a head-start on us in the game of evolution. May not this head-start have been maintained right down to date, thus producing at the bottom of the sea a race superior to anything upon the dry land?"

"But," Abbot had objected further, "if so, why haven't they come up to visit or conquer us? And why haven't we ever found any trace of them?"

"Quite simple to explain," the old professor had replied. "Any creature who can live at the frightful pressures of the ocean depths could never survive a journey even halfway to the surface. It would be like our trying to live in an almost perfect vacuum. We should explode, and so would these denizens of the deep, if they tried to come up here. Even one of their dead bodies could not be brought to the surface in recognizable form. No contact with them will ever be possible, nor will they ever constitute a menace to any one—for which we may thank the Lord!"

George Abbot now reviewed this conversation as he crouched in his diving-sphere in the purple darkness of the marine depths. Yes, old Osborne would believe him. The diary must be written for Osborne's eyes.
