Every seaport city of China is a twin. It is two cities--one inland, narrow-streeted, paved with rubble stones; the other at sea, floating on bamboo reeds. The amphibious inmates of the marine town never go ashore, but are a species of otter or seal. Besides, they are first-class thieves, as well as cowardly, cruel pirates and wreckers. They will steal the sheathing from a copper-bottomed vessel in broad daylight, and at night a guard-boat is necessary for protection. They will defy a sentry on shipboard--steal his ship from under him while he is wondering what he is set to guard. They are all expert divers, as familiar with the sea-bottom as with their own ugly little hovels. Such a native was found, and for a dollar spotted the submerged vessel in her matrix of sand and coral. "Now set a guard-boat," said the Englishman, "or he will steal the line, to get another dollar for finding the smuggler again." But the want of experts defeated the plan, after all. It was necessary to use a petard to lay bare the treasure, and no one had the necessary skill. When the American consented to lost time and defeat the cyclone threw another spoil in his way. The East like the West Indies is the brooding-place of storms, which in gyratory coils, like a lasso thrown wide and large, go twisting north by west. It caught a French frigate in the loop, and flung her poor bones on the coral reefs, and the hungry sand absorbed her. It is a peculiarity of those seas. But she was found, and the petard, like a huge axe wielded by a giant's arms, cut into her treasure-house and rescued it. The American's expenses for a journey round the world were paid. I have heard a sufficiently incredible story of a man submerged in a Chinese junk and under water twelve hours, yet taken out alive. A Chinese junk is the nightmare of marine architecture. It is owned in partnership by a company, but there is this difference from an ordinary charter-party. Each man owns his share or allotment of the vessel, and it is divided off into actual compartments or boxes made water-proof; and each one of these pigeon-holes the hong or merchant owns and stocks to suit himself. All open out upon the upper deck, and are battened down--sometimes with a glass skylight if used as a chamber. The structure in junk form is the thing's proper registry, since any departure from the ancient model would subject her to heavy taxation as an alien vessel. [2] It is a very effectual mode of preventing any improvement in shipbuilding among the Chinese.
