On their arrival in Tokio, our young friends looked around to discover in what the city differed from Yokohama. They saw the same kind of people at the station that they had left in Yokohama, and heard pretty nearly the same sounds. Porters, and others who hoped to serve them and thereby earn something, gathered around; and they found in the open space in front of the station a liberal number of conveyances ready to take them wherever they wanted to go. There were carriages and jin-riki-shas from which they could choose, and it did not take them long to decide in favor of the jin-riki-sha. It was a novelty to them, though not altogether so, as they had seen it in Yokohama, and had tried its qualities in their journey from the hotel to the station in the morning. "What is the jin-riki-sha?" the reader naturally asks. Its name comes from three words, "jin," meaning man; "riki," power; and "sha," carriage: altogether it amounts to "man-power-carriage." It is a little vehicle like an exaggerated baby-cart or diminutive one-horse chaise, and has comfortable seating capacity for only one person, though it will hold two if they are not too large. It was introduced into Japan in 1870, and is said to have been the invention of an American. At all events, the first of them came from San Francisco; but the Japanese soon set about making them, and now there are none imported. It is said that there are nearly a hundred thousand of them in use, and, judging by the abundance of them everywhere, it is easy to believe that the estimate is not too high. The streets are full of them, and, no matter where you go, you are rarely at a loss to find one. As their name indicates, they are carriages drawn by men. For a short distance, or where it is not required to keep up a high speed, one man is sufficient; but otherwise two, or even three, men are needed. They go at a good trot, except when ascending a hill or where the roads are bad. They easily make four and a half or five miles an hour, and in emergencies can do better than the last-named rate. Frank and Fred were of opinion that the jin-riki-sha would be a slow vehicle to travel in, but asked the Doctor for his experience of one in his previous visit to the country. "On my first visit to Japan," replied Doctor Bronson, "this little carriage was not in use. We went around on foot or on horseback, or in norimons and cangos." "And what are norimons and cangos?" "They are the vehicles in which the Japanese used to travel, and which are still much employed in various parts of the country. We shall see them before long, and then we shall have an excellent opportunity to know what they are. We shall probably be travelling in them in a few days, and I will then have your opinion concerning them.
