The first minutes were the most terrible to the bold adventurer; the feet and hands must grow accustomed to the rude task imposed on them, and they only gradually learn to find, as it were instinctively, their resting places; and this remark, which may appear erroneous to certain persons, who, fortunately for themselves, have never been obliged to try the experiment, will be recognized as rigorously true by all travellers who have been compelled to ascend or descend mountains. After a few minutes, when the mind remains at liberty, the body assumes of its own accord the necessary equilibrium, the feet find secure resting places, and the hands settle unhesitatingly on the grass or roots which offer them the indispensable degree of resistance.

John Davis had hardly gone ten yards down, ere he found himself on a wide ledge covered with thick shrubs; hitherto the descent had been extremely rapid. Lighting himself by the torch, the American traversed in every direction this species of esplanade, which was about a dozen paces in circumference; and, on carefully examining the thick shrubs which covered it, the adventurer perceived that the tops had been broken as if they had received a tremendous blow.

Davis looked around him. He soon concluded that this enormous gap could only have been made by the fall of two bodies: this remark gave him good hope, for at so slight a distance from the mouth of the abyss, the two enemies must have been full of life; the rapidity of their fall must have naturally been arrested by the shrubs; they might have met at various distances similar obstacles, and consequently have undergone several comparatively harmless falls. This hypothesis, erroneous though it was, still might be true.

John Davis continued his descent; the slope became constantly less abrupt, and the adventurer met within his passage, not merely shrubs, but clumps of trees, grouped here and there. Still, as John Davis found no further traces, a fear fell upon him, and painfully contracted his heart; he was afraid lest the shrubs, through their elasticity, might have hurled the two unhappy men into space, instead of letting them follow the slope of the precipice. This thought so powerfully occupied the American's mind, that a deep discouragement seized upon him, and for some moments he remained without strength or will, crouching sadly on the ground.

But Davis was a man of too stern a character, and endowed with such an energetic will, to give way for any length of time to despair: he soon raised his head, and looked boldly around him.

"I must go on," he said in a firm voice. But, at the moment when he prepared to continue his descent, he suddenly gave a start of surprise, and uttered a cry as he rushed quickly toward a black mass, to which he had hitherto paid but slight attention.

We once again ask our readers' pardon for the improbability of the following detail; but we repeat that we are not explaining, but narrating, confining ourselves to telling the truth, without pretending to discuss the greater or less possibility of facts, which, however extraordinary they may appear, are exactly true.

The white-headed eagle, the most powerful and the best provided of the birds, ordinarily builds its nest on the sides of barrancas, at the top of the loftiest trees, and chiefly those denuded of branches to a considerable height, but they are never found on rocks. This nest, strongly built, is composed of sticks from three to five feet in length, fastened together and covered with Spanish braid, a species of cryptogamic plant of the lichen family, wild grass, and large patches of turf. When the nest is completed, it ordinarily measures from six to seven feet in diameter, and at times the accumulation of materials there is so considerable—for the same nest is frequently occupied for a number of years, and receives augmentations each season—that its depth equals its diameter. As the nest of the white-headed eagle is very heavy, it is generally placed in the centre of a fork formed by the fortuitous meeting of several large branches.

John Davis, by the help of his torch, had just discovered a few yards from him, and almost on a level with the spot where he was standing, an eagle's nest, built on the top of an immense tree, whose trunk descended for a considerable depth in the precipice.

Two human bodies were lying stretched across this nest, and the American only required one glance to assure himself that they were those of the Jaguar and the Mexican Captain. They were perfectly motionless, and still fast locked in each other's arms.
