“ The principal industry of the state, however, is mining—its mineral resources including gold, silver, copper, mercury, lead and coal. The silver mines of Chihuahua are among the richest in Mexico, and include the famous mining districts of Batopilas, Chihuahuilla, Cosihuiriachic, Jesús María, Parral, and Santa Eulalia or Chihuahua el Viejo. ”

“ Agriculture has made little progress in Chihuahua, and the scarcity of water will always be a serious obstacle to its development outside the districts where irrigation is practicable. The climate and soil are favourable to the production of wheat, Indian corn, beans, indigo, cotton and grapes, from which wine and brandy are made. The principal grape-producing district is in the vicinity of Ciudad Juárez. Stock-raising is an important industry in the mountainous districts of the west, where there is excellent pasturage for the greater part of the year. ”
