"I'm sure they're there," she insisted. "They were locked in the safe." "But, don't you see," protested the poor man, "he can't get outside of that bell to get 'em." "I don't see _why_ he can't, if he should really try. I think it's too mean! They were my grandmother's jewels." "But, my dear, how could he get out?" "Well, _how does he get in?_ What's his radio-control good for; won't that help him? What is he going down there for if he can't do a little thing like that, to oblige?" She pouted at her husband because he persistently refused to present her request to Cosmo, and declared that she would do it herself, then, for she must have those jewels, now that they were so near. But Cosmo was saved from this, and other equally unreasonable demands, by a warning from De Beauxchamps that all was ready, and that no time should be lost. Then everybody hastened out on the decks to watch the departure of the adventurers. Many thoughtfully shook their heads, predicting that they would never be seen again. As soon as this feeling began to prevail the enthusiasm quickly evaporated, and efforts were made to dissuade Cosmo and De Beauxchamps from making the attempt. But they were deaf to all remonstrance, and pushing out of the chattering crowd, Cosmo ordered the gangway about the bell to be cleared of all bystanders. The opposition heated his blood a little, and he began to bear himself with an air which recalled his aspect when he quelled and punished the mutiny. This was enough to silence instantly every objector to his proceedings. Henceforth they kept their thoughts to themselves, although some muttered, under their breath such epithets as "fool" and "harebrain." In about half an hour after Cosmo's speech the bell, with its hardy explorers safely inclosed within, was lowered away, and a minute later hundreds were craning their necks over the rails to watch the shining globe engulf itself swiftly in the sapphire depths. It was about nine o'clock in the morning when the descent was begun, and for a long time, so remarkable was the transparency of the water, they could see the bell sinking, and becoming smaller until it resembled a blue pearl. Sometimes a metallic flash shot from its polished sides like a gleam of violet lightning. But at length it passed from view, swallowed up in the tremendous watery chasm. We turn now to trace the adventures of the bell and its inmates as they entered the awful twilight of the ocean, and, sinking deeper, passed gradually into a profundity which the sun's most powerful rays were unable to penetrate. Fortunately every one of the adventurers left a description of his experiences and sensations, so that there is no lack of authentic information to guide us.
