Through the assistance of a gentleman to whom Doctor Bronson had a letter of introduction, our friends were enabled to pay a visit to the imperial mint at Osaka. They found a large establishment, like a foundry, on the bank of the river, and just outside the thickly settled portion of the city. A tall chimney was smoking vigorously, and gave signs of activity; and there was an air of neatness about the surroundings quite in keeping with what they had observed thus far in their journey through Japan. They were met at the entrance by the director of the mint, a Japanese gentleman who had spent a considerable time in Europe and America, and spoke English with fluency and precision. They were invited to seats in the office, and, after a brief delay, were escorted through the establishment. The mint at Osaka is one of the most noted enterprises which the government of Japan has undertaken, and likewise one of the most successful. When it was founded it was under foreign supervision, and the most of the employés were from Europe; but year by year the Japanese have learned how to conduct its machinery, and have relieved the foreigners of the labor of managing it. The direction is Japanese, and so are the heads of the departments, and the employés from highest to lowest. When the mint was established, the machinery for it was imported from Europe, but at present it is all made by the Japanese, in their own factory attached to the mint. "Just to think," said Frank, "that people persist in calling these Japanese 'barbarians!' Here are machines for stamping coin and performing all the work of a mint, and it bears the mark of the Japanese. Here are delicate balances for weighing gold and silver and getting the weight down to the fraction of a grain, and they are just as sensitive and as well made as the best specimens from the French or German makers. If the Japanese can do all this, and they certainly have done it, they deserve to be considered just as good as any other people in the world." The Doctor took from his pocket some of the coin which was in circulation, and with which the boys had by this time become thoroughly familiar. They had remarked that it was as neatly made as any coin of Europe or America, and, as a matter of curiosity, they were desirous of seeing the machine by which each of the different pieces was stamped. The director kindly pointed out the various machines, and the boys observed that, with a single exception, they were all of Japanese make. Then they were shown through a factory for the manufacture of sulphuric acid that is attached to the mint, and is run on government account. They were somewhat astonished to learn that all the sulphuric acid used in the mint was made there, and that in the previous year thirteen thousand cases were exported to China. For the benefit of his professor of chemistry, Fred made the following memorandum concerning the branch of business he was investigating:
