Incessant noises, nameless sounds, make themselves heard without a break in these mysterious regions—the grand voices of the solitude—the solemn hymn of the invisible world, created by the Almighty.

In the bosom of these redoubtable forests the wild beasts and reptiles, which abound in Mexico, find refuge; here and there one meets with paths incessantly trodden for centuries by jaguars and bisons, and which, after countless meanderings, all debouch on unknown drinking holes.

Woe to the daring mortal who, without a guide ventures to tempt the inextricable mazes of these immense seas of verdure! After ineffable tortures, he succumbs, and falls a prey to the savage beasts. How many hardy pioneers have died thus, without the possibility of the veil being lifted which shrouds their miserable end! Their blanched bones, discovered at the foot of some tree, alone can teach those who come upon them that on that spot men have died, a prey to infinite suffering, and that the same fate, perchance, awaits the finders.

The stranger must have been the constant guest of the forest into which he had so audaciously plunged at the moment when the sun, quitting the horizon, had left the earth to darkness—darkness rendered still denser in the covert, in which the light even at midday could only struggle in at intervals through the tufted branches.

Bending a little forward, eye and ear on the watch, the unknown advanced as rapidly as the nature of the ground under his horse's hoofs would let him, following unhesitatingly the capricious deviations of a wild animal's path, whose traces were scarcely discoverable amidst the tall grasses which strove continually to efface it.

He had already ridden for several hours without having slackened the pace of his horse, plunging deeper and deeper into the forest.

He had forded several rivers, scaled many a steep ravine, hearing at a short distance, on right and left, the hoarse growlings of the jaguar and the mocking wailing of the tiger cat, which seemed to follow him with their menacing yells.

Taking no heed of roar or tumult, he continued his route, although the forest assumed a more dreary aspect at every step.

The bushes and trees of low growth had disappeared, to make room for gigantic mahogany trees, century old cork trees, and the acajou, whose sombre branches formed a vaulted roof of green eighty feet above his head. The path had grown wider, and stretched, in a gentle incline, towards a hillock of moderate height, entirely free from trees.

Arrived at the base of the hillock, the stranger halted; then, without dismounting, cast a searching glance on all around.
