"I know that. And if we leave the diving bell at all it will have to be in those new steel-ribbed diving suits we had made in Washington especially for this trip," concluded the young diver. The _Swallow_ lay at rest on the broad bosom of the mighty Pacific Ocean. Nothing had been seen of the _Raven_, and at present not a sign of a strange sail showed itself anywhere. It was high noon, and Captain Broadbeam had just concluded his calculations to prove that he was at the very spot which was said to be that where the _Happy Hour_ had sunk. Dave looked thoughtfully over the side, into the greenish waves, lit for a depth of only thirty or forty feet below the surface. What fortune did that silent body of water hold for his father and himself? A touch on his elbow aroused him, and turning, he found his parent standing beside him. Amos Fearless could not say a word, but he motioned to the water and smiled. Then he spoke to Dave in the sign language of the divers. "This is the spot," he signed. "How soon does Captain Broadbeam calculate to let us go down?" "I think to-morrow," replied Dave. A long talk followed, by word of mouth on Dave's part and by signs on the part of the parent. It was a sad sight to see Amos Fearless try to talk with his mouth and fail. His tongue would cling to his teeth and refuse to budge. At last he turned away with tears in his eyes and Dave was equally affected. The remainder of the day was spent in getting the diving bell into shape for use. This was inspected with great care, for it was understood by all that the two divers, father and son, would be taking their lives in their hands in going down such an immense distance as contemplated. "It's queer we don't see anything of the _Raven_," said Dave to Captain Broadbeam. "Perhaps Lemuel Hankers knows enough to keep out of our reach," was the answer. "He may know that we--or rather, you--are on board and have exposed Pete Rackley, and he may wish to keep his own head out of danger." "That must be it." "If Hankers came near us I would be apt to make it hot for him." "And I'll do the same." It was a clear day overhead when Dave and his father entered the diving bell and were hoisted over the side of the _Swallow_. Slowly the immense cable unwound itself, letting the bell down deeper and deeper. Soon the light of day was shut out and all became as black as night and as cold as a tomb. Amos Fearless turned on the electric current and the diving bell sent out several rays of light. The light attracted numerous fish, who swam up swiftly, only to stop just as fast and gaze stupidly through the glass of the bell's sides.
