At the appointed time they were off. They went through the foreign part of Yokohama, and through the native quarter, and then out upon the Tokaido. The boys were curious to see the Tokaido, and when they reached it they asked the Doctor to halt the jin-riki-shas, and let them press their feet upon the famous work of Japanese road-builders. The halt was made, and gave a few minutes' rest to the men that were drawing them, and from whose faces the perspiration was running profusely. The Tokaido, or eastern road, is the great highway that connects Kioto with Tokio--the eastern capital with the western one. There is some obscurity in its history, but there is no doubt of its antiquity. It has been in existence some hundreds of years, and has witnessed many and many a princely procession, and many a display of Oriental magnificence. It was the road by which the Daimios of the western part of the empire made their journeys to Tokio in the olden days, and it was equally the route by which the cortége of the Shogoon went to Kioto to render homage to the Mikado. It is a well-made road; but as it was built before the days of wheeled carriages, and when a track where two men could ride abreast was all that was considered requisite, it is narrower than most of us would expect to find it. In many places it is not easy for two carriages to pass without turning well out into the ditch, and there are places on the great route where the use of wheeled vehicles is impossible. But in spite of these drawbacks it is a fine road, and abounds in interesting sights. [Illustration: A VILLAGE ON THE TOKAIDO.] Naturally the Tokaido is a place of activity, and in the ages that have elapsed since it was made many villages have sprang into existence along its sides. Between Yokohama and Tokio there is an almost continuous hedge of these villages, and there are places where you may ride for miles as along a densely filled street. From Tokio the road follows the shore of the bay until near Yokohama, when it turns inland; but it comes to or near the sea again in several places, and affords occasional glimpses of the great water. For several years after the admission of foreigners to Japan the Tokaido gave a great deal of trouble to the authorities, and figured repeatedly in the diplomatic history of the government. The most noted of these affairs was that in which an Englishman named Richardson was killed, and the government was forced to pay a heavy indemnity in consequence. A brief history of this affair may not be without interest, as it will illustrate the difficulties that arose in consequence of a difference of national customs.
