At two points in the narrow strait upon the east are ferries to carry passengers to the mainland. Kang-song, where the stream makes an abrupt turn between low cliffs, is the scene of the American expedition of 1871; near the southern entrance of the strait, and close to the ferry, are the forts which repelled the American storming-party. The famous rapids and whirlpool of Son-dol-mok, whose evil reputation is the terror of the coast, are close by. There are numerous forts dotted round the coast of the island, recalling the Martello towers of Great Britain. They were not all erected at one time; the majority of them date only from the close of the seventeenth century, having been raised in the early years of Suk-chong. The rampart upon the eastern shore, which frowns down upon the straits and river below, was erected in 1253. Ko-chong, of the Ko-ryö dynasty, fled before the Mongol invasion of that date, removing his Court and capital from Song-do to Kang-wha. Kak-kot-chi, where there is a second ferry, is a few miles beyond Kang-song. At the point where the ferry plies, the hill of Mun-su rises twelve hundred feet high from the water’s edge. From a junk a short distance from the shore it appears to block the straits, so closely do the cliffs of Kang-wha gather to the mainland. This little place became the headquarters of the French expeditionary force in 1866. The capital of the island, Kang-wha city, is a battlemented citadel, with walls fifteen _li_ in circumference, and four pavilioned city gates. It is a garrison town, beautiful in its combination of green vistas and ancient, crumbling walls. The Chino-Japanese War, so fatal to many of the old institutions of Korea, diminished the ancient glory of Kang-wha. For two hundred and sixty years prior to this campaign, Kang-wha ranked with Song-do, Kang-chyu, Syu-won and Chyön-chyön as one of the O-to, or Five Citadels, upon which the safety of the Empire depended. It controlled a garrison of ten thousand troops; the various officials numbered nearly one thousand. The change in the destiny of the kingdom brought a turn in the fortunes of the island, and it is now administered by an official of little importance. It is still, however, the seat of government for a widely scattered region, and the centre of trade and industry for some thirty thousand people. Agriculture is the staple industry; stone-quarrying and mat-making are other means by which the population exists. At the water’s-side there are salt-pans; a certain amount of fishing, a little pottery-making, smelting, the weaving of coarse linen, to which work the wives of the farmers devote themselves, complete the occupation of the inhabitants. One pursuit, horse-breeding, for which Kang-wha was once famous, is now completely abandoned.
