“ A costly artificial harbour has been built by the Mexican government to accommodate the traffic of the Tehuantepec railway. It is formed by the construction of two breakwaters, the western 3260 ft. and the eastern 1900 ft. long, which curve toward each other at their outer extremities and leave an entrance 635 ft. wide. The enclosed space is divided into an outer and inner harbour by a double line of quays wide enough to carry six great warehouses with electric cranes on both sides and a number of railway tracks. ”
