He won. He never knew how far the enemy planes had pursued, or whether they had come near him or not. He knew only that suddenly there was a yellow band of sandy land deep, deep under him, that the next instant trees and hills swept past like little color-prints, and that he came to earth. Then he reached for a flask. And then he looked to wonder where he had landed. And then he heard the roar of a motor on one side of him, and the roar of a motor on the other. “Hands up!” shouted a man in khaki, leaning from the side of a swaying, drunkenly rolling car. He put up his hands, laughing hysterically. Fifteen minutes later the telephone bells rang in the forts on Fisher’s Island, Plum Island, in the Narragansett Harbor defenses, and in the headquarters of the field army. It told them that the enemy transports were thirty miles south of Nantucket Island, standing in for Block Island Sound or Long Island. _Unleashing the Submarines_ Up from Fisher’s Island under the Connecticut shore mounted an army hydro-aeroplane. It rose 2,000 feet, and circled there, [Illustration: “Up mounted a hydro-aeroplane.”] with such graceful, steady wheelings that despite its constant speed, it seemed to be soaring in lazy spirals like a sleepy gull. Under the two fliers in the machine lay the eastern entrance of Long Island Sound--the watergate to New York, with half-open jaws whose fangs were the guns of Fisher’s Island on the north and Plum Island on the south. Utterly harmless and innocuous seemed those two jaws, for not even the keenest eye could make out from above anything more savage than grassy mounds and daintily graded slopes of earth. Not even the sharpest glass could see within those pretty models in relief the dragons of 12-inch mortars that squatted in hidden pits sixteen in a group, or the sleek, graceful rifled cannon whose secret machinery could swing their thirty-five tons upward in an instant and as instantly withdraw them after they had spat out their half ton of shot. Between the guarding jaws there was deep water--deep and beautifully green. One of the airmen spoke to the other, who was looking out to sea through his glasses. “There they go,” he said, nodding to indicate the water below. Both looked. They looked into fifty feet of ocean, but their height made it but as a thick pane of dim green glass. They saw things moving, deep down. They were sleek and gray, like small whales. But they had snouts longer and sharper than any whale that ever swam. Three of them there were, moving out to sea through the entrance, steadily, at about ten knots an hour. _The Wait for the Enemy to Strike_ An hour passed. The men in the hydro-aeroplane descended, and their reliefs went up. They circled for an hour. Sometimes they drifted out to sea till the land was lost behind them.
