"My heart! We have them on the hip! We'll e'en shin up the shrouds and lower the mainsail. She's furled on the yards, but we can unreeve her 'ithout noise, and when she's down, she'll be a barricade betwixt the mainmast and the break o' the poop, and not a knave of them can see what is toward in the waist."

Dennis applauded the notion, and the two instantly set about their task. Crawling to the starboard side, they crept along by the rope netting that replaced in the waist the wooden bulwarks which bounded the decks, and reached the shrouds of the mainmast unperceived by the enemy in the cabin. To swarm up was the work of a few moments to Turnpenny, and Dennis was little less expert, having practised himself on the Maid Marian in many details of the mariners' duties. Gaining the yards, they cast off the robands, made the buntlines fast, then, easing the earings, lowered away by the buntlines and the clew-garnets. Scarcely five minutes after they had left the shelter of the rope-coil, a wall of canvas shut the waist from the view of the Spaniards.

They had barely finished their task when two musket-shots rang out, and two holes were cut in the sail. Clearly the enemy was on the alert. There was no time to be lost. Turnpenny knocked out the battens as quickly as possible, and lifting the hatch, disclosed a small ladder leading down into the lazaretto.

"I will go down," said Dennis, "being of less bulk than you, Amos."

He climbed nimbly down, struck a light, and after a little search discovered a jar of powder among a miscellaneous collection of ship's stores. Hoisting the jar up, he gave it into the hands of Turnpenny, climbed up again, and returned with the sailor to the coil of rope, to be out of harm's way while they went on with their preparations.

"If we fire the whole jar we shall of a surety sink the ship," said Dennis; "and that I am loath to do. We must needs make a petard; but how?"

"That cook knave shall find us a tin vessel, or I'll firk him," said Turnpenny.

He went into the forecastle. Dennis heard a brisk exchange of bad Spanish; then the sailor returned, with a small canister out of which he poured a heap of peppercorns.

"Most admirable!" said Dennis, who had meanwhile forced off the top of the jar. Making a hole in the rim of the canister near the lid, he filled the vessel with powder and firmly closed it.

"There's our petard, Amos. Now to place it."
