When Lee Hemingway learned of the offer, he determined to earn it. It was rather early in the season for our emblematical birds to hatch their young, but, by carefully watching a pair, he succeeded in finding where their nest was made. It was on the summit of an almost insurmountable bowlder, rising nearly a hundred and twenty-five feet in the valley of the Guadaloupe.

The bravest man might well shrink from attempting to scale the perpendicular sides of this mass of rock, but as young Hemingway gazed longingly up the side to the nest, he noticed that the stone had become coated, in the course of time, with earth, which was covered with tangled vines and stunted vegetation.

"I believe I can climb that," thought the sturdy lad, after scrutinizing the herculean task, and watching one of the eagles soaring far above the summit. "I think there is enough foothold, and I can use the vines to help pull me up; but, if the eagles should catch me at it, they would make music."

It was the birds that caused him more dread than the forty odd yards of rock. We knew their fierce nature, and, if they discovered his designs against their home, as they were almost certain to do, they would assail him with a fury that must be resistless in his cramped position.

The professor advised him not to make the attempt, but the daring youth had to earn his own living, and the prize of fifty dollars was too tempting to be resisted.

"I'll do it!" he exclaimed, after considering the question, "if you will keep watch with your gun for the eagles."

"Of course I'll do that," replied the professor, delighted with the prospect of securing that which he had sought so long in vain.

The preparations for the work were simple. With a basket, furnished with a lid, slung to his back, in which to secure the eggs or eaglets, young Hemingway began his laborious and dangerous ascent, while the professor, gun in hand, watched him from the ground below.

The boy quickly proved the possession of unusual skill as a climber. With the help of the vines he went steadily upward, hunting secure places for his feet and testing every support before trusting his weight to it. Once or twice, the professor thought the lad had made a mistake and was on the point of paying the penalty, but he never faltered nor slipped. Higher and higher he ascended until at last the feat was accomplished, and the very summit reached.

His heart throbbed with pleasure when he discovered two young eagles in the nest. They were no more than a couple of days old, and he had no trouble in placing them and a portion of the nest in the basket, which was again strapped to his back, and, after a brief rest, he started to descend.
