"The Higueras district, in the State of Coahuila, Mexico, is little known even in Mexico; and it is probably safe to say that not one out of every hundred engineers in the United States has even heart of it. This is easily accounted for by the fact that the district is small and relatively unimportant economically. Also, as one becomes more accustomed to think of mines, such as some of the big copper deposits, with productions running into thousands of tons daily, there is a tendency to pass over the small ones, giving them only a passing thought, if that. Though there have been, and still are, many mines with productions of only a hundred or so tons per day which are giving larger returns on their investments than are some of the larger producers"--Introduction, page 1.
