“And suppose some nimble crustacean should wriggle into your clockwork—”
“It would be a pressing sort of invitation for me to stop,” said Elstead, turning his back on the water and staring at the sphere.
They had swung Elstead overboard by eleven o’clock. The day was serenely bright and calm, with the horizon lost in haze. The electric glare in the little upper compartment beamed cheerfully three times. Then they let him down slowly to the surface of the water, and a sailor in the stern chains hung ready to cut the tackle that held the lead weights and the sphere together. The globe, which had looked so large on deck, looked the smallest thing conceivable under the stern of the ship. It rolled a little, and its two dark windows, which floated uppermost, seemed like eyes turned up in round wonderment at the people who crowded the rail. A voice wondered how Elstead liked the rolling. “Are you ready?” sang out the Commander. “Aye, aye, sir!” “Then let her go!”
The rope of the tackle tightened against the blade and was cut, and an eddy rolled over the globe in a grotesquely helpless fashion. Some one waved a handkerchief, some one else tried an ineffectual cheer, a middy was counting slowly: “Eight, nine, ten!” Another roll, then with a jerk and a splash the thing righted itself.
It seemed to be stationary for a moment, to grow rapidly smaller, and then the water closed over it, and it became visible, enlarged by refraction and dimmer, below the surface. Before one could count three it had disappeared. There was a flicker of white light far down in the water, that diminished to a speck and vanished. Then there was nothing but a depth of water going down into blackness, through which a shark was swimming.
Then suddenly the screw of the cruiser began to rotate, the water was crickled, the shark disappeared in a wrinkled confusion, and a torrent of foam rushed across the crystalline clearness that had swallowed up Elstead. “What’s the idee?” said one A. B. to another.
“We’re going to lay off about a couple of miles, ’fear he should hit us when he comes up,” said his mate.
The ship steamed slowly to her new position. Aboard her almost every one who was unoccupied remained watching the breathing swell into which the sphere had sunk. For the next half hour it is doubtful if a word was spoken that did not bear directly or indirectly on Elstead. The December sun was now high in the sky, and the heat very considerable.
“He’ll be cold enough down there,” said Weybridge. “They say that below a certain depth sea-water’s always just about freezing.”
