“ Grazing receives considerable attention in the uplands, where the temperature is favourable and the pastureage good, and hides are largely exported. Mining, however, is the chief industry, Sinaloa being one of the richest mineral-producing states in the republic. ”

“ The largest of these are the Culiacán, Fuerte and Sinaloa, the last two having short navigable courses across the lowlands.
Rain is plentiful everywhere, except in the extreme north, where the conditions are arid. The climate of the low-lying coast lands is hot and malarious, but in the mountains it is cool and healthy. Cereals and mezcal are produced on the uplands, and sugar, rum, coffee, tobacco, grape spirits and fruit in the lower zones. ”

“ Gold, silver, copper, iron and lead are found. There are also salt deposits and mineral springs. The best-known silver mines are the Rosario, from which about $90,000,000 had been extracted up to the last decade of the 19th century, and the Nuestra Señora de Guadalupe de los Reyes, discovered early in the 19th century and yielding over $85,000,000 before its close. ”
