railroad has exceeded all calculations, and yet it is but partially developed, the rolling stock being quite inadequate to the demand for freight transportation. In minerals it would seem as though the list of products was unequaled. At present the silver mines are undoubtedly the greatest source of wealth to the country, though under proper conditions the agricultural capacity of the land would doubtless exceed all other interests in pecuniary value, as indeed is the case in most other gold and silver producing countries. The principal mineral products of Mexico are iron, tin, cinnabar, silver, gold, alum, sulphur, and lead. In the state of Durango, large masses of the best magnetic iron ore are found, which at some future day will supply the material for a great and useful industry. Other iron mines exist, and some have been utilized to a limited extent. Coal is found in abundance, notably in the states of Oaxaca, Sonora, Nuevo Leon, and Coahuila. These coal measures are particularly valuable in a country many parts of which are treeless and without economical fuel. The total coinage of silver ore in the mints of Mexico to this date, we were intelligently informed, amount to the enormous aggregate of three thousand millions of dollars, to which may be added, in arriving at the total product of the mines, the amount exported in bars and the total value consumed in manufactures. This last item amounts to a much larger figure than one who has not given the subject careful thought would be prepared to admit.
