"There are two American lines of steamers running northward to California, and to Mexican and Central American ports, and there are English, French, German, Chilian, and Peruvian lines reaching to all the ports of the west coast of South America. The most important of all these lines are the Pacific Mail (American), running northward, and the Pacific Steam Navigation Company (English), running to the south. When the Isthmus route was the favorite way of travel between the Atlantic and Pacific coasts of the United States there were sometimes two or three American lines between Panama and California, but at present there is only one. "There was formerly a line between Panama and Australia, but it was discontinued long ago, and a line from here to the Sandwich Islands, Japan, and China has been talked of, but never established. When the Panama Canal is completed it is probable that the business of this port will be greatly increased, and the number of daily arrivals and departures will far exceed those of the most active times of the 'rush' for California." Dr. Bronson and the youths left the hotel about two o'clock in the afternoon, and proceeded to the dock whence the tender was to carry them to their steamer. The ships of the Pacific Steam Navigation Company run in connection with the Royal Mail Line from England to Aspinwall; the arrival of the English steamer at Aspinwall had been announced by telegraph, and the train with the passengers and mails was due in Panama about half-past two. While they were seated on the tender, and engaged in studying the beautiful panorama of the bay, the whistle of the locomotive was heard, and soon the train rolled into the station, and its burden was transferred to the boat. The passage to the steamer was quickly made, and by four o'clock the great craft was on her southerly course. [Illustration: COAST SCENE BELOW PANAMA.] As our friends leaned over the rail, Dr. Bronson gave the youths some reminiscences of the old days of California travel. "On the voyage from New York to Aspinwall," said he, "passengers became pretty well acquainted with each other; and it generally happened that there were some practical jokers among them, who indulged in tricks for creating amusement. One of the standing jokes of the departure from Panama was, to create alarm among those who were making the voyage for the first time, by spreading a report that they had embarked on the wrong steamer, and were being carried to Callao." "How could they do that?" Fred inquired.
