The Han, the river of the capital, lies about one hundred miles to the southward of the Taidong, and flows westwardly in a nearly parallel direction thereto, from the central ranges of the peninsula into the Yellow Sea. Its many branches join in a common estuary near the centre of the Yellow Sea coast, and their collective drainage area comprises a large portion of central Korea. Still farther to the southward is the Keum, traversing a fertile rice-growing country, while at the extreme south is the Nakdong. The latter is one of the most important streams of Korea, and the facilities that it affords for communication and interchange have done much towards rendering the district through which it flows one of the most fertile and prosperous of the land. The coasts of Korea are forbidding to the mariner and seem well adapted for the preservation of the seclusion that it has been so long the national policy to maintain. On the east, facing Japan, unbroken lines of steep hills, void of harbors, bend abruptly into the deep waters of the Japan Sea. To the westward countless outlying islands extend seaward many miles, liberally interspersed with rocks and shoals, between which eddy swift streams of tide-water. The terrors of the Maelstrom would find their counterpart in many a Korean whirlpool, which, forming in the vicinity of some submerged ledge, will cause a large vessel to heel suddenly well over, and will swing her many points off her course in a way to make the stoutest hearted captain tremble for the safety of his charge. The climate of Korea exhibits wide ranges of temperatures and hygroscopic conditions. In the northeast province, Ham-kiung-do, the winter is as rigorous as that of Nova Scotia; at the extreme south, on the island of Quelpaert, it somewhat resembles that of Louisiana. The warmth of Quelpaert is due to the proximity of the Kura-siwo, or Black Stream of Japan, the Gulf Stream of the Pacific, part of which is here turned into a cul-de-sac, from which it escapes with difficulty. One result of this is the creation of a stormy region near the island, where the mariner may at all times look for a hard blow. A characteristic feature of Yellow Sea coasts are the Chang-ma, or mid-summer rains, which set in with fair regularity in July and during their month's duration resemble in phenomena and general effects the periodic rains of the tropics. The winters, in all but the southern parts of the country, are long and severe and set in with great suddenness. As an illustration of the rapidity of this change I remember that on one occasion I was ferried across the Han river near the capital at a time when the only indication of cold weather was a film of ice along the river banks, and that within forty-eight hours afterwards I rode back across the river ice on horseback, over the line of the former ferry.
