Something did happen before ten minutes had passed. When Mago had given his instructions to the helmsman, and had superintended a slight shifting of the canvas, he looked again at the distant ship. It had become sensibly larger. The wind had freshened out at sea, and was rapidly bringing the stranger nearer. Mago hurried below to rouse his uncle. The old man was soon up on deck.

"I wish we were ten miles nearer home," he muttered, after taking a long look into the distance. "Get the oars out. If she is an enemy, and wants to cut us off, half a mile may make all the difference."

The order was promptly obeyed, and the rowers bent to their work with a will. But all the will in the world could not make the Melcart move very fast through the water. She was stoutly built, as became a ship that had to carry a precious burden through all weather, and she was foul with the long sea-voyage. The goal of the race between her and the stranger, which could now be seen to be a Roman ship-of-war, was a headland behind which, as Hanno knew, was the harbour of Chelys. Let her reach that and she was safe. But it seemed as if this was not to be. The Roman ship had what wind there was right aft, and, notwithstanding all the efforts of the Melcart's crew, moved more rapidly through the water. She would manifestly cut off the Melcart before the headland was reached. But Hanno was not yet at the end of his resources.

"Call Mutines," he said to his lieutenant.

Mutines was a half-caste Carthaginian, whose thick lips, flat nose, and woolly hair indicated a negro strain in his blood. "Mutines," said the old man, "you used to have as good an aim with the catapult as any man in Carthage. If your hand has not lost its cunning, now is the time to show your skill. Knock that rascal's steering-gear to pieces, and there is a quarter-talent for you."

"I will do my best, sir," said Mutines; "but I am out of practice, and the machine, I take it, is somewhat stiff."

The catapult, which was of unusual size and power, had been built, so to speak, into the ship's forecastle. It could throw a bolt weighing about 75 lbs., and its range was 300 yards. While Mutines was preparing the engine, word was passed to the rowers that they were to give six strokes and no more. That, as Mutines reckoned, would be enough to bring him well within range of the enemy. The calculation was sufficiently exact. When the rowers stopped, the two ships, having just rounded the headland, were divided by about 350 yards. The impetus of the Melcart carried her over about 100 more. When she was almost stationary Mutines let fly the bolt. He had never made a happier shot. The huge bullet carried away both the tillers by which the steering-paddles were worked. The ship fell away immediately, and the Melcart, for whose rowers the fugleman set the liveliest tune in his repertory, shot by, well out of range of the shower of arrows which the Roman archers discharged at her. In the course of a few minutes she had reached the harbour of Chelys.

But her adventures were not over. The captain of the Roman ship was greatly enraged at the escape of his prey. To capture so famous a prize would mean certain promotion, and he was not prepared to resign his hopes without an effort to realize them. As soon as the steering-gear had been temporarily repaired, he called his sailing-master, and announced his intention of following the Carthaginian into the harbour.

The man ventured on a remonstrance. "It's not safe, sir," he said; "I don't know the place, but I have heard that the water is shallow everywhere except in the channel of the stream."

"You have heard my orders," returned the captain, who was a Claudius, and had all the haughtiness and obstinacy of that famous house. The sailing-master had no choice but to obey.
