"The Japanese currency," said Doctor Bronson, "has had a somewhat checkered career. Previous to the coming of the foreigners, the currency consisted of gold, silver, copper, and bronze coins. The Daimios had money of their own, and some of them had issued paper kinsats, or money-cards. These were on thick paper, like card-board, and they circulated freely, though sometimes at a discount, owing to the difficulty of redemption or the wasteful ways of the prince by whom they were put forth. The old coins were oval or oblong, and the lower denominations had a square hole in the centre, so that they could be strung on a wire or on a cord. The gold coins were known as 'kobans,' while the silver ones had the general name of 'boos.' There were fractions of each, and they had their names, just as our half and quarter dollars have their distinctive names. The unit of the silver coin was a 'boo,' and it was always called 'ichiboo,' or one boo. The word _ichi_ means _one_, but the early visitors supposed it was a part of the name of the coin. Thus we read in books of twenty years ago that the writer paid 'one ichiboo' or 'two ichiboos' for certain purchases. It is the same as if some one writing of America should say that he paid 'one one-dollar' or 'two one-dollars' for what he had bought. [Illustration: ICHI-BOO.] "All that old currency has been set aside," continued the Doctor, "and the country is now in possession of a decimal system of money. The coins are round, and the general stamp on them is the same, apart from the words and figures showing the denomination and value. The unit is the 'yen,' which is equal to our dollar. In fact, the Japanese currency is assimilated to our own in weight, fineness, and decimal divisions. Here is the table of the values: "10 rin make 1 sen, equal to 1 cent. 100 sen make 1 yen, equal to 1 dollar. "The coins are stamped with the devices of the coiled dragons and the rising sun (both Japanese symbols), and not with the portrait of the Mikado. Japanese prejudice is opposed to the adoption of the picture of the imperial ruler on the coin of the country, but it will probably be overcome in time. It is less severe than with the Moslems (among whom a true believer is forbidden to make a picture of anything that has life), and consequently will be more easy to do away with.
