The late Sylvanus Miller, civil engineer, who was engaged in railroad enterprise in Central America, was seeking local support for a road and attempted to give the matter point. He asked a native:
"How long does it take you to carry your goods to market by muleback?"
"Three days," was the reply.
"There's the point," said Miller. "With our road in operation you could take your goods to market and be back home in one day."
"Very good, senor," answered the native. "But what would we do with the other two days?"
