Smith smiled. The first lieutenant broke in—

"Look-out reports, sir, another aeroplane was sighted behind Mr. Smith's."

The admiral, who had been an amused auditor of the colloquy between Captain Bolitho and his lieutenant, was a man of intuitions.

"There are no aeroplanes on this coast except the two with the Reds," he said. "Mr. Smith, you have now reported yourself for duty. Our single aeroplane has broken down; we must impress yours for public service. I will not ask you what you have seen; but you will at once follow the strange aeroplane, and endeavour to find out the position and course of the enemy's fleet."

In less than a minute Smith was in the air; in ten minutes he had overtaken the Red aeroplane, flying high as he approached, and hovering over his late pursuer, who made vain efforts to rise above him. The immense engine power of the Puck gave her as great an advantage over her rival in soaring as in horizontal speed. By the rules of the manoeuvres the Red aeroplane was out of action as soon as the Puck rose vertically above her. Wasting no further time, Smith continued his course, and in half-an-hour sighted the Red squadron, noted its strength and course, and in another half-hour was back on the deck of the Imperturbable.

"I found the enemy, sir, about ninety miles S.S.E., eight battleships and about a dozen scouts. Their course was west."

The admiral made a rapid calculation.

"By Jove!" he said, "they will catch Pomeroy before we join him. But there's time yet. We can warn Pomeroy to meet us twenty miles north-east of the spot previously arranged. I think, Captain Bolitho, we may perhaps overlook Mr. Smith's little irregularity in joining if he gives us a full account of his—er—experiences, after dinner to-night."

"And the Reds, sir?"

"Before dinner, one or the other of us will be out of action. Whether Reds or Blues, we shall have leisure to hear how Mr. Smith went round the world in seven days."
