"The Panama Railway has been the most profitable thing of the kind in the world," said the Doctor, "or, at any rate, one of the most profitable I ever heard of. The managers have generally kept their affairs as much as possible to themselves, and would, doubtless, assure you that they had lost money by their investment, which is often the case with men who have a remunerative business of any kind. The local fare over the line between Aspinwall and Panama was established at twenty-five dollars, and remained at that figure for nearly twenty years. Twenty-five dollars for a ride of forty-eight miles, or more than fifty cents a mile! Thousands of passengers were carried over the road every month, and every thousand passengers meant twenty-five thousand dollars to the railway. At one time the steamships were carrying steerage passengers from New York to San Francisco for eighty dollars, including the transit of the Isthmus; the steamship company thus received fifty-five dollars for carrying a passenger five thousand five hundred miles, including his board and lodging for twenty-three days, while the railway company received almost half as much for carrying him forty-eight miles, lodging him four hours in rickety cars, and giving him no board whatever.

This involved a tedious journey up the Chagres River by bongoes or native boats as far as Gorgona, and a ride thence over the hills and through the mud to Panama. The riding was done on the backs of mules, as there was no wagon-road; travellers were often obliged to pass the night in the open air, as there were very scanty accommodations in the few villages along the road; a week or more was generally consumed in the trip; the prices of everything were exorbitant; and the tourist generally reached the end of his journey feeling very much as if he had been passed through a patent wringing-machine. Not a few fell ill and died on the way, and many a fevered sufferer in California, years afterwards, could trace the beginning of his ills to his exposure on the Isthmus. 'Isthmus fever' became known almost as a distinct malady, and it was often very difficult of cure. It is pretty well forgotten now, thanks to the rapid transit afforded by the railway. Under all the circumstances, the enterprising men who constructed this road deserve every cent they received from it; it has saved thousands of lives to the population of the United States and other countries, and has added materially to the commercial facilities of the world. It was built under many discouragements, and the energy displayed in its construction was worthy of a liberal reward." [Illustration: A BONGO.]
