We were still gazing on the spot where this fearful tragedy was enacted, transfixed and mute with horror, when the shark again rose to the surface, bearing in his jaws the lifeless body of the English sailor; and for a brief period we beheld the voracious fish devouring his human food. The cargo of the Dolphin being completed, there ensued the usual bustle and confusion in making preparations for sea. Owing to the lateness of the season, Captain Tilton was unwilling to encounter the storms of the New England coast in a vessel hardly seaworthy, and expressed an intention to proceed to Charleston, in South Carolina. About a week before we left Demarara a small English brig-of-war arrived in the harbor, causing much consternation among the sailors, and not without reason. The brig was deficient in her complement of men, and this deficiency was supplied by impressment from crews of British vessels in port. The commander was a young man, who in common with most of the British naval officers of that day, had an exalted opinion of his dignity and importance, and held the Yankees in contempt. The pennant at the main is a distinguishing mark of a man-of-war, and it was considered disrespectful on the part of the master of a merchant vessel to wear a pennant in the presence of a cruiser. But on the Sunday following the arrival of the gun brig the captain of a fine-looking American brig, who did not entertain that respect for John Bull which the representatives of that dignitary were disposed to exact, hoisted his colors, as usual, on the Sabbath. He did not confine his display of bunting to the ensign at the peak, a burgee studded with stars at the fore, and a jack on the bowsprit, but ran up a pennant of most preposterous length at the main, which proudly flaunted in the breeze, as if bidding defiance to the Englishman. The young naval commander foolishly allowed himself to be annoyed by this proceeding on the part of the Yankee, and resolved to administer an appropriate rebuke. He sent an officer alongside the American brig, who, in a peremptory tone, told the mate to cause that Yankee pennant to be hauled down immediately. The captain, hearing of the mandate, made his appearance on deck; and on a repetition of the order from the officer, exhibited unequivocal symptoms of a choleric temper. After letting off a little of his exuberant wrath, he declared with emphasis that he had a RIGHT to wear a pennant, and WOULD wear it in spite of all the officers in the British navy. The midshipman, finding it of no avail to continue the parley, told his cockswain to go aloft and "dowse the pennant and leave it in the cross-trees." This was done, regardless of the protest of the captain, and his threats to lay the subject before the government and make it a national matter. The boat had hardly reached the man-of-war, when the pennant was again flying on board the American brig, and seemed to wave more proudly than before.
