Map showing railroads in operation in South America—railroads shown by heavy black lines.
The South and Central American countries may be said to need aeroplanes and dirigibles to solve their problems of transporta-
tion. In most of those countries railroad transportation is limited to the central places, and the process of transportation even
in central places, is often slow and costly on account of long detours made necessary by mountains, waterways and undeveloped
country. The aircraft going as it does, over all obstacles at high speed, would solve many problems of transportation. For
mail carrying it would be unsurpassable in efficiency. South and Central America are larger than the United States and every
country of the Pan-American Union is destined to become a large nation.
