The boys agreed at once to the proposal, and the conversation came to an end. The Doctor went to arrange for the proposed journey, and the youths brought out their writing materials, and devoted the rest of the afternoon to the preparation of letters in answer to those they had just received. [Illustration: ARRIVAL OF THE FRENCH MAIL STEAMER.] The French steamer arrived from Shanghai in the evening, and her great hull loomed majestically in the light of the full-moon as she came to anchor. It is a condition of the contracts for the transportation of the mails, that a steamer is not to lie more than twenty-four hours at any of the stopping-places along the route unless detained by unforeseen accidents. Consequently, when one of these ships arrives, it is pretty certain that her departure will occur within the time above specified; and it was shortly announced that the ship in question would leave at noon the next day. The mail service between Europe and the Far East is performed almost as regularly as that across the Atlantic, and the arrivals at the various points can be guessed with tolerable accuracy. The English and French steamers perform each a fortnightly service both ways, and, as they run alternately, the residents of China and Japan have weekly mail-days for sending and receiving their letters. Doctor Bronson engaged passage for the party by the French steamer as far as Saigon, and then went to the office of the "Yuen Fat Hong" to ascertain if there was a vessel for Bangkok by way of Cochin China. In the last few years the Chinese merchants have gone somewhat extensively into the business of running steamships. There is a company with a capital of two million dollars that owns several lines of steamers along the coast and on the great river of China, the Yang-tse-kiang, and its officers and stockholders are all of them Chinese. There are several smaller companies, and there are Chinese commission-houses that act as agents for English and other steamers in the Eastern trade. The Yuen Fat Hong was one of these commission-houses, and it managed the business of a line of English ships running between Hong-kong and Bangkok, with an occasional call at Saigon. [Illustration: PRIVATE PARLOR OF THE "YUEN FAT HONG."] Doctor Bronson found the office without any difficulty, and was shown into a neatly-arranged parlor, where four well-dressed Chinese were sitting. Three of them were holding fans in their hands, while the fourth was indulging in the luxury of a pipe. Plants in pots stood near the walls, and there was a table in the centre of the room, where the oldest and most serious of the Oriental gentlemen was seated. Evidently it was a time of relief from labor, and so there was no delay in attending to the inquiries of the Doctor.
