"As to the jin-riki-sha," he continued, "my experience with it in my last visit to Japan since its introduction gives me a high opinion of the Japanese power of endurance. A few days after my arrival, I had occasion to go a distance of about forty miles on the great road along the coast, from Yokohama to Odiwara. I had three men to draw the carriage, and the journey was made in twelve hours, with three halts of fifteen minutes each. You could not have done better than this with a horse and carriage in place of the man-power vehicle. On another occasion I went from Osaka to Nara, a distance of thirty miles, between ten in the morning and five in the afternoon, and halted an hour for lunch at a Japanese inn on the road. Part of the way the road was through fields, where it was necessary to go slowly, and quite frequently the men were obliged to lift the vehicle over water-courses and gullies, and a good deal of time was lost by these detentions." Both the boys declared that the travel under such circumstances was excellent, and that it was fully up to what the average horse could accomplish in America. [Illustration: JAPANESE ON FOOT.] "The next day," said the Doctor, "I went on from Nara to Kioto, which was another thirty miles, in about the same time and with a similar halt for dinner. I had the same men as on the day before, and they raced merrily along without the least sign of fatigue, although there was a pouring rain all day that made the roads very heavy. Frequently there were steep little hills to ascend where the road passed over the water-courses or canals. You will find, as you travel in Japan, that the canals are above the general level of the country, in order to afford the proper fall for irrigation. Where the road crosses one of these canals, there is a sharp rise on one side, and an equally sharp descent on the other. You can manage the descent, but the rise is difficult. In the present instance the rain had softened the road, and made the pulling very hard indeed; and, to add to the trouble, I had injured my foot and was unable to walk, so that I could not lighten the burden of the men by getting out of the carriage at the bad places.
