On two successive days there were tremendous thunderstorms, the second succeeded, just as we were at the head of a wild glen, by a brief tornado, which nearly blew over the ponies, and snapped trees of some size as though they had been matchwood. Then came a profound calm. The clouds lay banked in pink illuminated masses on a sky of tender green, cleft by gray mountain peaks. Mountain torrents boomed, crashed, sparkled, and foamed, the silent woods rejoiced the eye by the vividness of their greenery and their masses of white and yellow blossom, and sweet heavy odors enriched the evening air. On that and several other occasions, I recognized that Korea has its own special beauties, which fix themselves in the memory; but they must be sought for in spring and autumn, and off the beaten track. Dirty and squalid as the villages are, at a little distance their deep-eaved brown roofs, massed among orchards, on gentle slopes, or on the banks of sparkling streams, add color and life to the scenery, and men in their queer white clothes and dress hats, with their firm tread, and bundled-up women, with a shoggling walk and long staffs, brought round with a semicircular swing at every step, are adjuncts which one would not willingly dispense with. Before reaching the Paik-yang Kang, a broad, full river, an affluent of the northern Han, with singularly abrupt turns and perpendicular cliffs of a formation resembling that of the Palisades on the Hudson River, we crossed one of the great lava fields described by Consul Carles.[19] This, which we crossed in a northeasterly direction, is a rough oval about 40 miles by 30, a tableland, in fact, surrounded by a deep chasm where the torrents which encircle it meet the mountains. Its plateaux are from 60 to 100 feet above these streams, which are all affluents of the Han, and are supported on palisades of basalt, exhibiting the prismatic columnar formation in a very striking manner. In some places the lava, which is often covered either with conglomerate or a stiffish clay, is very near the surface, and large blocks of it lie along the streams. It is a most fertile tract, and could support a large population, but not being suited for rice, is very little cultivated, and grows chiefly oats, millet, and beans, which are not affected by the strong winds. There are two Dolmens, not far from the Paik-yang Kang. In one the upper stone is from 7 to 10 feet long, by 7 feet wide, and 17 inches deep, resting on three stones 4 feet 2 inches high. The other is somewhat smaller. The openings of both face due north.
