It will be seen by reference to our table on page 88 of this volume, that the value of the products of Zacatécas in the ten years from 1835 to 1844, was $43,384,215; giving a mean annual rate of $4,338,421, and exhibiting the important fact, in spite of revolutionary troubles and consequent social, commercial and industrial disorganization, that the mineral yield of this region, instead of diminishing, has steadily increased with every year.

Here we perceived two ruined heaps of stones, flanking the entrance to the causeway, ninety-three feet broad, commencing at four hundred feet from the cliff.

Hence the grand
