I advanced with all caution; for, left without a guide in this labyrinth, I did not know which way to go. I soon heard in the distance the dull sound of the pickaxes with which they were hewing away the rock, mingled with mysterious noises which seemed to come from a lower gallery. These sounds, though very indistinct, served to guide me. Since entering the mine, I had seen only those passages in which the ore had been all extracted. I was now impatient to behold a spot in which the miners were actually at work. Such a locality is called the labor— that is to say, the place where they are following the vein of silver. A dusky, obscure glimmer indicated that the proximity of the place was not far off; and I soon reached the orifice of a shaft not very deep, from which a strong light proceeded. I descended it by means of a wooden ladder placed zigzag. I hesitated at first to trust myself to this rickety ladder; but, emboldened by the shallowness of the shaft, I ventured to descend, and arrived safely at the bottom. A passage about five feet wide, and six hundred in length, conducted me along this underground hive, the air in which was as hot and stifling as if it had left the mouth of a crater. Lost in the midst of this crowd of workmen, who were too busy to notice my presence, I could examine at my ease the fantastic tableau which there met my eyes.
