"Is it the Slapping Sal, sir?"

"I have no doubt of it, Mr. Wharton."

"They don't seem to like the look of us, sir. They've cut their cable and are clapping on sail."

It was evident that the brig meant struggling for her freedom. One little patch of canvas fluttered out above another, and her people could be seen working like madmen in the rigging. She made no attempt to pass her antagonist, but headed up the estuary. The captain rubbed his hands.

"She's making for shoal water, Mr. Wharton, and we shall have to cut her out, sir. She's a footy little brig, but I should have thought a fore-and-after would have been more handy."

"It was a mutiny, sir."

"Ah, indeed!"

"Yes, sir, I heard of it at Manilla: a bad business, sir. Captain and two mates murdered. This Hudson, or Hairy Hudson as they call him, led the mutiny. He's a Londoner, sir, and a cruel villain as ever walked."

"His next walk will be to Execution Dock, Mr. Wharton. She seems heavily manned. I wish I could take twenty topmen out of her, but they would be enough to corrupt the crew of the ark, Mr. Wharton."

Both officers were looking through their glasses at the brig. Suddenly the lieutenant showed his teeth in a grin, while the captain flushed a deeper red.
