[Illustration: WAY STATION ON THE RAILWAY.] Near the door of the restaurant was the office of a money-changer, its character being indicated by signs in at least half a dozen languages. Passengers were exchanging their Austrian money for Russian, and the office seemed to be doing an active business. "That fellow has about as good a trade as one could wish," said the Englishman, as he nodded in the direction of the man at the little window. "Two trains arrive here daily each way; for people going north he changes Austrian into Russian money, and for those going south he changes Russian into Austrian. He receives one per cent. commission on each transaction, which amounts to four per cent. daily, as he handles the money four times. I have often envied these frontier bankers, who run no risk whatever, provided they are not swindled with counterfeits, and can make twelve hundred per cent. annually on their capital. But perhaps they have to pay so dearly for the privilege that they are unable to get rich by their business. By-the-way," said he, changing the subject abruptly, "did you observe the stout lady that stood near us in the anteroom of the passport office?" [Illustration: BEFORE EXAMINATION.] "Yes," answered the Doctor, "and she seemed quite uneasy, as though she feared trouble." "Doubtless she did," was the reply, "but it was not on account of her passport. She was probably laden with goods which she intended smuggling into Russia, and feared detection. I noticed that she was called aside by the custom-house officials, and ushered into the room devoted to suspected persons. She isn't here yet, and perhaps they'll keep her till the train has gone. Ah! here she comes." [Illustration: AFTER EXAMINATION.] Frank and Fred looked in the direction indicated, but could not see any stout lady; neither could the Doctor, but he thought he recognized a face he had seen before. It belonged to a woman who was comparatively slight in figure, and who took her seat very demurely at one of the tables near the door. "That is the stout lady of the anteroom," said the Englishman, "and her form has been reduced more rapidly than any advocate of the Banting or any other anti-fat system ever dreamed of. She was probably detected by her uneasy manner, and consequently was subjected to an examination at the hands of the female searchers. They've removed dry goods enough from her to set up a small shop, and she won't undertake smuggling again in a hurry. Import duties are high in Russia, and the temptation to smuggle is great. She was an inexperienced smuggler, or she would not have been caught so easily. Probably she is of some other nationality than Russian, or they would not have liberated her after confiscating her contraband goods."
