"It is worth trying, anyhow," the captain said.

And a score of the sailors were at once sent down to fetch up the bales. Ropes were fastened round these, and they were laid along by the bulwarks in readiness for being lowered instantly. Ten bales were placed on each side, and three men told off to each bale.

By this time they were halfway to the mouth of the harbour, and the preparations were completed just in time, for the small boats suddenly drew aside, and two of the largest of the pirates' craft, each rowed by twenty-four oars, dashed at her, one on each side. The captain shouted the order, and the men all sprang to their feet. It was seen at once that the vessels would both strike about midships. Three bales on either side were raised to the bulwarks, and lowered down with the ropes until close to the water's edge and closely touching each other. Francis sprang on to the bulwark and superintended the operations on one side, while the captain did the same on the other.

"A few feet more astern, lads. That is right. Now, keep the bales touching. You are just in the line."

An instant later the Bonito reeled from the shock of two tremendous blows. The bows of the pirates were stove in, but the thick bales enabled the Bonito to withstand the shock, although her sides creaked, the seams started, and the water flowed in freely. But of this the crew thought little. They were occupied in hurling darts, arrows, and combustibles into the pirates as these backed off, in an already sinking condition.

"Now I think we can go," the captain said, and ordered the whole of the oars to be manned.

They were speedily got out, and the Bonito made her way out through the mouth of the harbour. The pirates, in their lighter boats, rowed round and round her, shooting clouds of arrows, but not venturing to come to close quarters, after the fate which had befallen the four largest vessels of their fleet.

As soon as they were clear of the islet the sails were hoisted. The wind had fallen much during the night, and had worked round to the east, and under sails and oars the Bonito left the island, none of the pirates venturing to follow in pursuit. The oars were soon laid in, and the men, with mallets and chisels, set to work to caulk the seams through which the water was making its way. The casualties were now inquired into, and it was found that six men had been shot dead, and that nine-and-twenty had received wounds more or less severe from the arrows of the pirates.

Francis had been twice wounded while superintending the placing of the bales. One arrow had gone through his right leg, another had struck him in the side and glanced off a rib.

"This won't do, Messer Francisco," the captain said as he assisted Giuseppi to bandage the wounds. "Signor Polani placed you on board to learn something of seamanship and commerce, not to make yourself a target for the arrows of pirates. However, we have to thank you for the saving of the Bonito, for assuredly she would have been stove in, had not the happy thought of hanging those bales overboard struck you. It would be of no use against war galleys, whose beaks are often below the waterline, but against craft like these pirates it acts splendidly, and there is no doubt that you saved the ship from destruction, and us from death, for after the burning of the two first vessels that attacked us, you may be sure they would have shown but little mercy. I can't think how you came to think of it."
