The morning after their departure from Nagasaki, Frank went on deck soon after daylight. The wind was so strong that it almost took him from his feet, and he was compelled to grasp something to make sure of remaining upright. The sky was overcast, and every few minutes there came a sprinkling of rain that intimated that the cabin was the better place for any one who was particular about keeping dry. Fred joined him in a few minutes, and soon after Fred's arrival the Doctor made his appearance. [Illustration: THE THUNDER DRAGON.] The Captain was on the bridge of the steamer, and appeared much disturbed about something, so much so that the boys asked Dr. Bronson if he thought anything had gone wrong. The Doctor gave a hasty glance at the sky and the water, and then retreated to the cabin, where a barometer was hanging. A moment's observation of the instrument satisfied him, or, rather, it greatly dissatisfied him, for he returned hastily to the deck and rejoined the boys with the observation, "We shall have it very lively in a short time, and are not likely to reach Shanghai in a hurry." "Why? What do you mean?" "I mean that we are about to have a typhoon." "I should rather like to see one," Frank remarked. "Well," the Doctor replied, "you are about to be accommodated, and if we get safely out of it I am very sure you will not want to see another. "But as we are in for it," he continued, "we must make the best of the situation, and hope to go through in safety. Many a strong ship lies at the bottom of the sea, where she was sent by just such a storm as we are about to pass through, and many another has barely escaped. I was once on a ship in the China seas, when the captain told the passengers that it would be a miracle if we remained half an hour longer afloat. But hardly had he done speaking when the wind fell, the storm abated, and we were safe. The typhoon is to these waters what the hurricane is to the West Indies; it is liable to blow at any time between April and September, and is often fearfully destructive. "The word typhoon comes from the Japanese 'Tai-Fun,' which means 'great wind,' and the meaning is admirably descriptive of the thing itself. There is no greater wind in the world than a typhoon; the traditional wind that would blow the hair off the back of a dog is as nothing to it. A cyclone is the same sort of thing, and the two terms are interchangeable; cyclone is the name of European origin, while typhoon comes from the Asiatic.
