"Sounds incredible, doesn't it," said Stanley with a smile. "But that's what we're going to do—if the Professor's gadget works as he seems to think it will."

"I don't think it, I know it," retorted the Professor. "And man, man, the things we may see down there! New and unknown species—a world no human has ever seen before—perhaps the secret of all of life—"

"Dragons, sea-serpents, and what not!" Stanley finished with a grin.

"Or, possibly—nothing at all." The Professor shrugged. "I mustn't let my scientific curiosity run away with me. Perhaps we'll find no new thing down down. Our deep sea dredging and classification may already embrace most of the forms of life in the greater depths."

"If it does I want my money back," said Stanley. "When you asked me to finance this expedition for you, I agreed on condition that you would show me a thrill—some real big game, even if I would not be able to shoot it. If we draw blank—"

"The mere descent should satisfy you, my adventuring friend," replied the Professor brusquely. "I think you'll find that thrilling enough."

"But—a mile under the surface!" I marveled, feeling not entirely comfortable. "The pressure! Enormous! It can't be done! That is, I mean, can it be done?"

"It had better be," said Stanley with a humor that I did not entirely appreciate. "If it isn't, the three of us are going to be pressed out like three sheets of tissue paper! For we are assuredly going down that far in the Professor's gadget."

"Was that the thing I saw hoisted aboard just before we left?"

"That was it. We'll stroll around after lunch and look it over."
