"Heaven be thanked, I am saved!" murmured Walter, as he rose from his uncomfortable position and wiped the perspiration from his forehead. "I must lose no time now, or perhaps one or both the old birds may return."
He pressed on with redoubled energy till an event occurred, unimportant in itself, but which caused him some uneasiness, and reminded him of the need of caution. The rock in places was fragile and split up by the weather, and with a slight touch of his foot he loosened an immense fragment of stone, which went rolling down the side of the mountain till it reached a projecting ledge hundreds of feet below. A pang of terror shot through the boy's heart, and his face blanched, as he watched the stone thundering over the obstacles in its way until it disappeared in a cloud of dust. It seemed as if the whole mountain trembled beneath him; a mist bleared his eyes; and as the blood rushed to his head, a deadly giddiness threatened to overpower him. He felt an impulse to throw himself over, which he could scarcely resist; and it was only by falling on his face and shutting his eyes that he recovered his presence of mind. After thus lying for several minutes, with beating heart and quaking limbs, until by degrees he became more at ease, he ventured to look around him once more, and fixed his eyes on the nest, which was now only about fifty paces farther on.
After waiting a few minutes longer, to be sure that his courage had returned, he made a fresh start, determining not to allow anything to alarm him again; and soon reached the end of the ridge, and viewed the nest with the young vultures before him. But here still another difficulty presented itself. The rock, which up to this point had been quite level, rose at the extreme end about eight feet above the ridge, and formed a sort of projecting platform, which the parent birds, with their wonderful sagacity, had deemed the most suitable spot on which to take up their abode. As he measured the height with his eye, Walter began to fear that after all he would be obliged to return without accomplishing his object, for the rock was so smooth as scarcely to afford the least hold to either his hands or feet. Fortunately, however, he recollected his little axe, which might do him good service if the stone, as he hoped, proved soft. Raising himself cautiously, he drew the axe from his belt, and while supporting himself with the left hand, dealt the rock several vigorous blows with the right, and to his great delight succeeded in making notches, by which, if he only went carefully to work, he could accomplish his object.
With renewed courage he clambered up the almost perpendicular rock, and his curly hair and sunburned face soon appeared above the edge of the nest. The next moment he leaned over, seized the young birds in spite of their angry cries, transferred them one after the other to his bag, and throwing it across his shoulder, began to return on the dangerous road by which he had come. In common, however, with the experience of all who have ascended precipitous heights, he soon found that going down was much more difficult than had been the coming up; but ignoring the fact that he had beneath him a precipice two thousand feet deep, he devoted all his attention to the work immediately before him, and carefully descended the rocky wall step by step, till he reached the level ridge once more. He then turned slowly round, slung his bag in front of him, and leaning back against the wall, surveyed the giddy road which he must traverse to reach the glacier and the steep declivities of the Engelhorn, and thereafter his native valley.
It was a difficult and dangerous road; but the young mountaineer's heart was now full of joy and confidence, for he had surmounted the greatest difficulty, and the prize of his bold and daring venture was in his possession. He uttered an exclamation of triumph; then, thanking God for the help he had received, he implored the Divine protection on his homeward journey. The sharp ridge made it necessary for him, as before, to work his way forward astride on the rock for some time; but he soon got within sight of a part where it would be possible to go on his hands and knees, and was just about to change his straddling position for the more comfortable one of crawling, when the constant shrieking of the young vultures in his bag was answered by a piercing cry from above, followed the next moment by the loud rushing of powerful wings close to his ear. The boy uttered an exclamation of horror, and clung with all his might to the rock to prevent himself from falling.
In an instant he perceived the fearful danger that threatened him. One, or perhaps both the old birds had been attracted by the cries of the young ones, and were about to avenge themselves on the robber of their nest. Walter guessed that a hard fight would probably take place, and his first impulse was to throw the bag with the young birds into the valley beneath, and then try to make his escape as well as he might. But he soon found that this plan was more readily formed than it could be executed; for before he could make a single movement, he felt the blast of the wings just above his head, while the screaming of the enraged bird so confused his senses that he had great difficulty to avoid being hurled from his narrow resting-place into the ravine below. This sudden danger, although it alarmed him for the moment, awoke the next moment the courage and determination of the brave-hearted boy. It was a case of life or death, and it was vain to think of retiring from the contest. So, snatching his axe from his belt, he aimed a powerful blow at the old vulture as she swept down upon him for the third time. He succeeded beyond his expectation, for the blow, made almost at random, struck the wing of the bird, which, after vainly attempting to continue the struggle, fell helplessly into the abyss.
