The silver mines here, which are old and famous, were discovered in the seventeenth century.

I was cordially received by Mr.A.R.

Shepherd, the well-known mining expert, whose courtesy and kindness were much appreciated by the members of the expedition.
My recent experience had convinced me that the only way to study the natives properly was to live among them for a length of time, and as such a thing was out of the question with so large a party as I still had with me, I made up my mind to discharge as soon as possible everybody and to remain alone.
The country was now suffering from a relentlessly scorching sun.

The heat increased as the wet season approached, and, as the animals were getting weaker and weaker, I disposed here of about half of them, and the number of attendants and the amount of baggage were correspondingly reduced.

On continuing the journey with the weak and hungry mules, we found the ascent of the southern side of Barranca de Batopilas quite laborious; but on the crest we enjoyed the fresh breeze, the more gratefully after the enervating heat in the bottom of the canon.
Thus we arrived at the village of Yoquibo (yoki = bluebird; ivo = mesa: bluebird on the mesa).
