The capital, Aguascalientes, named from the medicinal hot springs near it, is a flourishing commercial and manufacturing city.
It is well watered by numerous small streams and one larger river, the Aguascalientes or Rio Grande, and has a mild healthy climate with a moderate rainfall.
They inhabit the western Sierra Madre region from Sinaloa southward to Chiapas, the higher plateau states, which region was the centre of their empire when Cortes conquered them, and parts of Vera Cruz, Tabasco, Oaxaca, Morelos, Aguascalientes and San Luis Potosi.
A British consular report for 1904 stated that Mexico City and Torreon only were using electric traction, but that Guadalajara, Monterrey, Aguascalientes, Lagos, Colima, Vera Cruz and San Luis Potosi would soon be using it.
In the sierra regions of western Chihuahua and Durango, Nuevo Leon, Coahuila, Aguascalientes, San Luis Potosi, and the plateau states farther south, the rainfall is more abundant and the conditions more favourable.
