As a result of this difference in progress between the two nations, we have to describe a remarkable event, one of the most striking evidences that could be given of the practical advantage of modern civilization. Near the end of the century war broke out between China and Japan, and there was shown to the world the singular circumstance of a nation of 40,000,000 people, armed with modern implements of war, attacking a nation of 400,000,000--equally brave, but with its army organized on an ancient system--and defeating it as quickly and completely as Germany defeated France in the Franco-German War. This war, which represents a completely new condition of events in the continent of Asia, is of sufficient interest and importance to speak of at some length. Between China and Japan lies the kingdom of Corea, separated by rivers from the former and by a strait of the ocean from the latter, and claimed as a vassal state by both, yet preserving its independence as a state against the pair. Japan invaded this country at two different periods in the past, but failed to conquer it. China has often invaded it, with the same result. Thus it remained practically independent until near the end of the nineteenth century, when it became a cause of war between the two rival empires. [=Corea Opened to Foreign Intercourse=] Corea long pursued the same policy as China and Japan, locking its ports against foreigners so closely that it became known as the Hermit Nation and the Forbidden Land. But it was forced to give way, like its neighbors. The opening of Corea was due to Japan. In 1876 the Japanese did to this secluded kingdom what Commodore Perry had done to Japan twenty-two years before. They sent a fleet to Seoul, the Corean capital, and by threat of war forced the government to open to trade the port of Fusan. In 1880 Chemulpo was made an open port. Later on the United States sent a fleet there which obtained similar privileges. Soon afterwards most of the nations of Europe were admitted to trade, and the isolation of the Hermit Nation was at an end. Less than ten years had sufficed to break down an isolation which had lasted for centuries. In less than twenty years after--in the year 1899--an electric trolley railway was put in operation in the streets of Seoul--a remarkable evidence of the great change in Corean policy. Corea was no sooner opened to foreign intercourse than China and Japan became rivals for influence in that country--a rivalry in which Japan showed itself the more active. The Coreans became divided into two factions, a progressive one that favored Japan, and a conservative one that favored China. Japanese and Chinese soldiers were sent to the country, and the Chinese aided their party, which was in the ascendant among the Coreans, to drive out the Japanese troops. War was threatened, but it was averted by a treaty in 1885 under which both nations agreed to withdraw their troops and to send no officers to drill the Corean soldiers.
