BAPTISM, in the sea language, a ceremony in long voyages on board merchant ships, practised both on persons and vessels who pass the tropic or line for the first time. The baptizing the vessels is simple, and consists only in washing them throughout with sea-water; that of the passengers is more mysterious. The oldest of the crew, that has past the tropic or line, comes with his face blacked, a grotesque cap on his head, and some sea-book in his hand, followed by the rest of the seamen dressed like himself, each having some kitchen utensil in his hand, with drums beating; he places himself on a seat on the deck, at the foot of the mainmast. At the tribunal of this mock magistrate, each passenger, not yet initiated, swears he will take care the same ceremony be observed, whenever he is in the like circumstances: Then, by giving a little money by way of gratification, he is discharged with a little sprinkling of water; otherwise he is heartily drenched with streams of water poured upon him; and the ship boys are enclosed in a cage, and ducked at discretion.—The seamen, on the baptizing a ship, pretend to a right of cutting off the beak-head unless redeemed by the captain.
