“ Saltillo is on the Mexican National railway and another railway connects it with the important mining and industrial town of Torreon, on the Mexican Central. The city is on the great central plateau of Mexico, about 5200 ft. above sea-level. It has a cool and healthy climate, and is a resort in summer for the people of the tropical coast districts, and in winter for invalids from the north. The city is laid out in regular squares, with shady streets and plazas. ”
