A traveller, who wrote as recently as the seventeenth century, describes a ceremony which took place on board a ship in which he was sailing, when passing through the straits. Just as the two lofty headlands were in sight on either side of the ship, an old seaman came forward with a book, and summoning all those whose names he declared not to be registered in it, made them swear that they in future voyages would compel their fellow-seamen to perform the same ceremonies in which they were about to engage. Behind him appeared a band of veteran seamen dressed up in a variety of fantastic costumes, with a drum and other musical instruments. These forthwith seized on all whose names were not registered as having before passed through the straits, and dragging them forward, thrust them into tubs, and soused them thoroughly with water. No one was altogether exempt, but those who had before passed were allowed to escape a like process by the payment of a fine. These same mariners, when they extended their voyages to the southern hemisphere, very naturally postponed the ceremony which they were in the habit of performing on passing the straits, till they crossed the line. They also, not altogether abandoning classical allusions, changed the name of their _dramatis personae_. Hercules, who had no connection with the ocean, whatever he might have had to do with the Straits of Gibraltar, had to give place to Neptune, the long-honoured monarch of the main, and Amphitrite was introduced to keep him company. We recognise in the duckings, the sacrificial ablutions, and in the shaving and fining, the oaths and the penalty. When the hardy seamen of Great Britain first began to steer their ships across the line, they were undoubtedly accompanied by pilots and mariners of the Mediterranean. These, of course, taught them the ceremonies they had been in the habit of performing. The English, as may be supposed, made various additions and alterations suited to their rougher habits and ideas, and what at one time probably retained somewhat of the elegance of its classical origin, became the strange burlesque it now appears.
