The man then confessed that he had been employed by the Cavaliers to destroy the admiral and his flag-ship; that the cask was double-headed, and that the interior was filled with gunpowder and missiles of all sorts; that between the two heads there was a lock so contrived that on being opened it would fire a quick match and cause the whole to explode.

“As you understand its mechanism, you shall be employed in extracting its contents,” said the admiral.

The man on hearing this looked greatly disconcerted, but was forced to obey. The carpenter having provided him with tools, he descended into the boat, when she was towed some distance from the ship, where she was anchored, and the oars being removed, he was left to operate alone on the cask.

He was watched with great interest as he cut a hole through the bottom. This done, he took out the contents and hove them overboard, when he hailed to say that the cask was empty.

The admiral then ordered him and the two blacks to depart with a message for the Prince, informing him of the miscarriage of his enterprise.

The Prince afterwards, we heard, spread a report that he and his brother, while out hunting, had been attacked by a party of men from Admiral Blake’s fleet, and that he had in consequence allowed the attempt to be made to blow up the flag-ship. I should here say that on board the Prince’s fleet were many Republicans, who sent the admiral information of all his intentions. We now heard that, fearing lest the King of Portugal should no longer be willing to afford him protection, Prince Rupert proposed putting to sea, and seeking his fortune in another direction.

On this, a calm coming on, our ships were towed down to the mouth of the river, where we lay ready to intercept him, and so the Prince’s plan was defeated.

Some weeks went by, when Admiral Popham arrived with a strong reinforcement, and by one of the ships came letters to Lancelot and me, of which I will speak anon. The King of Portugal, just before this, throwing off all disguise, arrested several English merchants residing in Lisbon, and declared his intention of supporting the corsair princes.

No sooner was this news received on board our ships than the admiral sent word to the Portuguese government that he proposed to make reprisals. While the messenger was on the way, a number of ships were seen with all sails set coming out of the river. They proved to be richly-laden merchantmen bound for the Brazils. As they approached, our squadron got under weigh, and before the Brazilian ships had time to retreat we surrounded them and captured the whole. As they were well-armed, the officers and crews being removed, we sent all the men we could spare on board, and thus nine fine vessels were added to the strength of our fleet. Winter was approaching, and with it came heavy gales, greatly trying our ships. Information had been received that another richly-laden fleet from the Brazils was expected in the river. We accordingly, our ships having been carefully fitted to encounter the fiercest storms, got under weigh and stood out to sea in order to watch for it. We had not long to wait, when one of the look-out frigates brought intelligence which made us all on the alert.

The commander stated that he had counted no less than twenty-three sail approaching under all the canvas they could carry.
