Abstract

There is one feature of mining that has long been of especial interest. It is the distribution of the particularly rich ore mass or bonanza. In a recent visit to the celebrated silver mines of Pachuca, Mexico, unusual opportunity was offered me to carefully examine into some of the most instructive phases of this subject. The facts obtained throw light upon many vexed problems connected with many abandoned silver mines of our own country, still certainly containing large amounts of easily available ores.
