"By looking at the map, you will see that the Bay of Panama is enclosed between the mainland and the Peninsula of Azuero, the latter extending to the southward about seventy-five miles; consequently a steamer going to California must proceed in that direction, until she can turn the point of the peninsula. Most of the novices were not aware of this; the rumor was started, and, if incredulous, they were told to look at the compass and be convinced. The compass corroborated the assertion of the jokers, and many a traveller was seriously disturbed in mind until the joke was explained." "He was probably more careful in his study of geography after that experience," Frank remarked. "Sometimes," continued the Doctor, "the California steamers sailed at the same time as the ships of the English line for South America, and occasionally there was an international race as long as their courses were nearly the same. The routes diverge very soon, so that the races were brief, but, with a large number of passengers on board of each steamer, there would be great excitement while the competition lasted, and much money was wagered on the result. On one occasion, owing to the carelessness of somebody, one steamer ran into another, but no serious damage was done; at another time a steamer hugged the shore too closely in order to shorten her running distance and get an advantage over her rival. These accidents called attention to the racing, and the managers of the different companies issued a very stringent order against any more trials of speed. I have not heard of a repetition of these affairs for a good many years, and there is rarely any opportunity for rivalry, if we may judge by the time-tables of the various lines running from Panama. When steamers are to leave on the same day there is generally an hour or two between their departures, and the later one does not attempt to over-haul her predecessor." [Illustration: CAVE NEAR LIMON RIVER.] As the great ship moved steadily through the blue water of the Bay of Panama our young friends regarded with close attention the beautiful panorama that passed before their eyes. The land was on both sides of their course, the peninsula on the right, and the mainland of South America on the left; the horizon to the eastward was filled with the chain of the Cordilleras, which increase in height farther to the south, and form the lofty line of the Andes. One of the passengers who was familiar with the coast indicated to our friends the Gulf of San Blas, and other indentations which have come into prominence during the discussions about an inter-oceanic canal, and a good deal of geographical knowledge was imbibed in the first few hours of the voyage.
