“But if three sorts of admirals carry a red flag, how do you know one from another?”

“By the situation of the flag. The admiral of the fleet carries an Union Flag at the main-top-gallant-mast head, so that you may always know his ship. Then, other admirals carry their flags, let the colour be what it may, also at the main-top-gallant-mast head. The vice-admirals carry theirs at the fore-top-gallant-mast head, and the rear-admiral carries his at the mizen-top-gallant-mast head.”

“Oh, oh, that is it! Then we know at last what is the meaning of ‘the red flag at the fore.’”

“Yes, that must be now pretty plain to you. The marines are a very efficient part of the British force; they are not to be out-done either in courage or patriotism. For some time in my younger days I belonged to them, and it was then that I picked up what knowledge of nautical tactics I possess. Had not a handful of British marines stood in the breaches made by the soldiers of Buonaparte in the garrison of St. Jean D’Acre in the year 1799, and thereby called up a spirit of determination in the Turkish troops, the place must have surrendered. As it was, it held out, baffled Buonaparte with his bravest and his best, and rendered the repulse of the French, and the bravery of Sir Sidney Smith famous in history.”

“What have the marines to do?”

“They are trained to fight either on shore or on board ships; and oftentimes they make sad havoc among the enemy from the poop and the round-top. When a ship is boarded by an enemy, they sweep the decks with their muskets, or keep back the boarders with their bayonets. I knew some famous fellows among them, who were well acquainted with all the duties of a soldier and a seaman, and would run a boat through the water as if it were a catamaran.”

“What is a catamaran, uncle?”

“A catamaran is a species of boat used by the native Indians on the coast of Coromandel. It consists of only one plank, five feet long and two wide, on which the intrepid Indian kneels, and by means of a paddle propels himself along through the most terrific surf, bidding defiance to the warring of the elements and the overwhelming seas, which often hurl him from his perilous position, but which he as quickly and dexterously regains; and thus these amphibious beings afford communication with ships in distress, when no other boat could possibly live.”

“How many marines are there on board a large ship? one of the biggest ships that sails on the sea?”

“I will just run over a list of the crew of a first-rate, and then you will hear all about it. This is the list.
