After passing Keizan, mountain herbage had been brought down from the hills in large bales on cleverly constructed racks saddled to the backs of bullocks, and in one field we saw a man who had just come to his little field with an enormous load borne upon his easel-like packing appliance. Thus we find the Koreans also adopting the rice crop, which yields heavily under conditions of abundant water; we find them supplementing a heavy summer rainfall with water from their hills, and bringing to their fields besides both green herbage for humus and organic matter, and ashes derived from the fuel coming also from the hills, in these ways making good the unavoidable losses, through intense cropping. The amount of forest growth in Korea, as we saw it, in proximity to the cultivated valleys, is nowhere large and is fairly represented in Figs. 210, 213 and 214. There were clear evidences of periodic cutting and considerable, amounts of cordwood split from timber a foot through were being brought to the stations on the backs of cattle. In some places there was evident and occasionally very serious soil erosion, as may be seen in Fig. 214, one such region being passed just before reaching Kinusan, but generally the hills are well rounded and covered with a low growth of shrubs and herbaceous plants. Southernmost Korea has the latitude of the northern boundary of South Carolina, Georgia, Alabama and Mississippi, while the northeast corner attains that of Madison, Wisconsin, and the northern boundary of Nebraska, the country thus spanning some nine degrees and six hundred miles of latitude. It has an area of some 82,000 square miles, about equaling the state of Minnesota, but much of its surface is occupied by steep hill and mountain land. The rainy season had not yet set in, June 23rd. Wheat and the small grains were practically all harvested southward of Seoul and the people were everywhere busy with their flails threshing in the open, about the dwellings or in the fields, four flails often beating together on the same lot of grain. As we journeyed southward the valleys and the fields became wider and more extensive, and the crops, as well as the cultural methods, were clearly much better. Neither the foot-power, animal-power, nor the wooden chain pump of the Chinese were observed in Korea in use for lifting water, but we saw many instances of the long handled, spoonlike swinging scoop hung over the water by a cord from tall tripods, after the manner seen in Fig. 215, each operated by one man and apparently with high efficiency for low lifts. Two instances also were observed of the form of lift seen in Fig. 173, where the man walks the circumference of the wheel, so commonly observed in Japan. Much hemp was being grown in southern Korea but everywhere on very small isolated areas which flecked the landscape with the deepest green, each little field probably representing the crop of a single family.
