For minutes, then, the ship seemed to play hide-and-seek with the invisible fliers. The roaring noise overhead circled about, now near, now seeming very far away. And the siren sent its dismal blasts out into the grayness all about. Then, for an instant, a swiftly scudding shadow was visible overhead. It banked steeply and vanished, and seemed to have turned and come lower when it reappeared a moment later. It was not distinct, at first. It was merely a silhouette of darker gray against the all-enveloping mist. But its edges sharpened and became clear. One could make out struts, an aileron's trailing edge. "Got nerve, anyhow," said Bell grimly. It swept across the ship and disappeared, but the noise of its engines did not dwindle more than a little. The blast of the siren seemed to summon it back again. Once more it came in sight, and this time it dived steeply, flashed across the forecastle deck amid a hideous uproar, desperately, horribly close to the dangling derrick-cables, and was gone. * * * * * Bell had seen it more clearly than anyone else on the ship, perhaps. He saw a man in the pilot's cockpit between wings and tail reach high and fling something downward, something with a long streamer attached to it. Bell had an instant's glimpse of the goggled face. Then he was darting forward, watching the thing that fell. It took only a second. Two at most. But the thing seemed to fall with infinite deliberation, the streamer shivering out behind it. It fell at a steep slant, the forward momentum of the plane's speed added to its own drop. It swooped down, slanting toward the rail.... Bell groaned. It struck the rail itself, and bounced. A sailor flung himself toward it. The streamer slipped from his fingers and slithered over the side. Bell was at the railing just in time to see it drop into the water. He opened his mouth to shout, and saw it sink. The last of the streamer followed the dropped object down into the green water when it was directly below him. His hands clenched. Bell stared sickly at the spot where it had vanished. An instant later he had whirled and was thrusting wide the wireless room door. The operator was returning to his key, grinning crookedly. He looked up sidewise. "Tell them it went overside," snapped Bell. "Tell them to try it again. Ortiz is in hell! To try again! He's dying!" * * * * * The operator looked up fascinatedly, his fingers working his key. "Is he--bad?" he asked with a shuddering interest. "He's dying!" snarled Bell, in a rage because of his helplessness. He had forgotten everything but the fact that a man below decks was facing the most horrible fate that can overtake a man, and facing it with a steadfast gameness that made Bell's heart go out to him. "They don't die," said the operator. He shuddered. "They don't die of it." His key stopped. He listened. His key clicked again.
