The story of the coolie-trade and some of the conversation that followed cleared the mystery that surrounded the narrator and had given him the name by which he was known. He had been an active participant in the peculiar commerce of the East, which includes the violation of laws whenever they prove inconvenient, such as the smuggling of opium and the shipment of coolies to the countries where they are in demand. His latest venture was one that required considerable secrecy, as it involved the purchase of arms for the rebels in Japan. For this reason he had been very cautious in his movements around Yokohama and during his whole stay in Japan, and he had found it judicious to leave the country on the vessel that came so near being wrecked in the typhoon that overtook our friends. He was safely away from Japan now, and the arms that he had purchased for the rebels were in the hands of the government. He had made money by the operation, and was on the lookout for something new. "That man belongs to a class which is not at all rare in the far East," said Doctor Bronson to the boys when the subject of the conversation had left them. "A great many adventurers find their way here, some of them being men of ability which borders on genius, while the others are not far removed from rascals. Ward and Burgevine were of the better sort; and there are others whom I could name, but they are not so numerous as the other and worse variety. They are very often men of good manners, and not at all disagreeable as travelling companions, but it is not advisable to be intimate with them. Travelling, like poverty, makes us some strange acquaintances. We can learn a great deal from them if we proceed properly; and if we know where the line of familiarity should be drawn, we are not in any danger of suffering by it." The morning after the above conversation the steamer arrived at Hong-kong, and dropped anchor in the harbor. She was immediately surrounded by a fleet of small boats, which competed eagerly among themselves for the patronage of the passengers. Our friends selected one which was rowed by a couple of women, and had a group of children in a little pen at the stern. Doctor Bronson explained to the boys that in Southern China a great deal of the boating is done by women, and that entire families live on board the little craft on which they earn their existence. The boat population of Canton numbers more than sixty thousand persons. They are not allowed to live on shore, and their whole lives, from birth to death, are passed on the water. The most of the boatmen and boatwomen at Hong-kong come from Canton, which is only ninety miles away; and as they have privileges at the former place which are denied them in the latter, they are quite satisfied to stay where they are.
