Doctor Bronson relieved their doubt by handing them the letters of credit which had come in the bulky parcel in question. They were considered too valuable to be intrusted to the ordinary mail, and therefore they had been "registered." And from their experience with the Post-office in China and other Eastern countries, our three friends were unanimously of the opinion that all valuable letters going there should be sent by registered post. The Japanese postal service was the most perfect one they found in their travels, and the Doctor declared that some of our officials at home might learn what would be to their advantage if they would visit the post-office at Yokohama and see how admirably it was conducted. "Well, boys," said Dr. Bronson, "it's all settled." The boys had a moment of standing on tiptoe in their exuberant delight, and then Frank asked, "Where are we to go, Doctor, and when are we to start?" "That is what we must determine now," was the reply. "We have several routes open to us, and each has its advantages." "I think," answered Frank, "that we could not do better than leave the selection of the route to Doctor Bronson. He has proved such an excellent guide and friend thus far, that we have the most implicit confidence in his judgment, and are quite willing to adopt his suggestions without question." This was said as if Frank had been addressing himself to his cousin rather than the Doctor. Fred instantly accepted the proposal, and it was promptly agreed that the whole matter should be left in Doctor Bronson's hands to arrange. The latter thanked the youths for the expression of their confidence in him, and then proceeded to designate on the map the routes leading westward from Hong-kong. "The regular mail steamers," said he, "go from here to Singapore, which you see is down close to the equator, and at the entrance of the Straits of Malacca. The English steamers go directly there without stopping; but the French ones touch at Saigon, in Cochin China, which is a colony of the French Government." "I have thought out a plan," he continued, "while we have been waiting, and what I propose is this: "We will go from here to Saigon by one of the French ships, and then make a stay in Cochin China long enough to see what we wish of the country. Then we can find a trading-ship of some kind to take us to Siam, and once there, we shall have no trouble in getting to Singapore, as there is a regular line between that city and Bangkok, the capital of Siam. There is much to be seen in Siam, as well as in Cochin China; and I think this route will be far preferable to the direct one by the mail steamers, though it will not be so comfortable. We must be prepared to "rough it" a little both on shore and at sea, but our privations will be more than compensated by the abundance of interesting sights on the way."
