Further remarks concerning the rashness of Billy—otherwise Flight-sub-lieutenant Barcroft—were postponed by the appearance of yet another member of the "Hippodrome's" flying-officers.

"Young Barcroft's just tick-tocked through," he announced. "He's on his way back. Cool cheek, by Jove! Keeping the crowd of us waiting while he's joy-riding somewhere in the direction of Berlin. Wonder how far he went?"

From where they stood, just abaft the starboard funnel-casing, the officers scanned the horizon. The "Hippodrome," like most of her sisters, had at one time been a liner, but the building up of a launching-platform for seaplanes had resulted in considerable alterations to her external and internal appearance. Amongst other things she now had two funnels abreast and far apart in place of her original foremost one, in order to give full scope to the inclined plane that extended from her bows to within a few feet of the navigation bridge—a piece of new construction perched at least 150 feet further aft than the old bridge and chart-room of pre-war days.

The clank of a steam winch and the swinging overhead of a long steel derrick announced the fact that preparations were being made to welcome home the "stray bird." Although a seaplane could be launched with ease from the sloping platform, on her return she would have to alight in the water and "taxi" alongside her parent ship. Hence the necessity for a long and powerful derrick to swing the seaplane, with its broad expanse of wings, clear of the ship's side and deposit it carefully upon deck.

"Here he comes!" exclaimed Fuller, indicating a faint object in the eastern sky.

Rapidly it resolved itself into a large biplane with triple floats in place of the three landing wheels that form a necessary adjunct to army aeroplanes. Then the polished wood propeller, glinting in the oblique rays of the sun, could be discerned as it slowed down preparatory to the seaplane commencing a thousand feet glide.

With a succession of splashes the biplane took the water, "bringing up" with admirable judgment at a distance of less than fifty yards from the starboard quarter of the parent ship.

The seaplane carried a crew of two. The pilot pushing up a pair of goggles revealed a fresh-looking, clean-cut face that gave one the impression of a public school boy. Billy Barcroft was still in his teens. He had just another month to enter into his twentieth year. In height he was a fraction under five feet ten inches; weight—an important consideration from an airman's point of view—was "ten seven." Supple and active, he carried not an ounce of superfluous flesh. Standing up and lightly grasping a stay, he swayed naturally to the slight lift of the seaplane—the personification of that product of the Twentieth Century, the airman.

His companion, who had just completed the "winding in" of the trailing aerial, raised his head above the coaming surrounding the observer's seat. In appearance he resembled Barcroft so strongly-that the pair might have been taken for twin-brothers. But no relationship, save the ties of friendship and duty, existed betwixt Billy Barcroft and his observer, Bobby Kirkwood. The latter was an Assistant Paymaster, who, deserting the ship's office for the freedom of the air, had already mastered the intricacies of "wireless" and other qualifications necessary for the responsible duties of observer.

"You've been a jolly long time, you belated bird!" shouted Fuller in mock reproof. "What's the stunt?"
