Frank thought it was pretty nearly time to be thinking about the purchases he was to make for Mary. So he looked up the paper she gave him before his departure, and sat down to examine it. The list was not by any means a short one, and on consulting with the Doctor he learned that it would make a heavy inroad upon his stock of cash if he bought everything that was mentioned. He was rather disconcerted at the situation, but the good Doctor came to his relief. "It is nothing unusual," said he, "for persons going abroad to be loaded down with commissions that they are unable to execute. A great many people, with the best intentions in the world, ask their friends who are going to Europe to bring back a quantity of things, without stopping to think that the purchase of those things will involve a heavy outlay that cannot be easily borne by the traveller. The majority of people who go abroad have only a certain amount of money to expend on their journeys, and they cannot afford to lock up a considerable part of that money in purchases that will only be paid for on their return, or quite as often are never paid for at all. There is a good little story on this subject, and it may be of use to you to hear it. "A gentleman was once leaving New York for a trip to Europe, and many of his friends gave him commissions to execute for them. Some were thoughtful enough to give him the money for the articles they wanted; but the majority only said, 'I'll pay you when you get back, and I know how much it comes to.' When he returned, he told them that a singular circumstance had happened in regard to the commissions. 'The day after I sailed,' said he, 'I was in my room arranging the lists of things I was to get for my friends, and I placed the papers in two piles; those that had the money with them I put in one pile, and the money on top; and those that had no money with them I put in another pile. The wind came in and set things flying all around the room. The papers that had the money on them were held down by it, but those that had no money to keep them in place were carried out of the window and lost in the sea. And so you see how it is that the commissions that my friends gave me the money for are the only ones I have been able to execute.' "But in the present case," said Doctor Bronson, "it is all right, as your father privately gave me the money to buy the articles your sister wants. So you can go ahead and get them without any fear that you will trench on the amount you have for your personal expenses." The boys went on a round of shopping, and kept it up, at irregular intervals, during their stay in Japan. And in their shopping excursions they learned much about the country and people that they would not have been likely to know of in any other way.
