COSTA RICA.

A railroad has been projected from Port Limon, near the tenth parallel of latitude on the Atlantic, to Caldera, in the Gulf of Nicoya. Rising to an altitude of 5,100 feet the route passes through a salubrious climate, and over a productive soil. A macadamized road, 134 miles long, with five stone bridges, has been completed along this line. As a route for a ship canal the altitude of the summit appears to exclude it from further consideration.
