Across his shoulders was slung a stout bag, in which he intended placing the little eagles when he secured them. In one hand he carried a stout stick for use in an emergency: the other hand grasped the rope.

Down, down he went until just in front of the eyrie. Then he slipped one leg through the loop at the end of the cord and turned to look into the dark hole, where he could hear the eaglets “talking.”

Slowly he swung round, bracing his foot against the rocky wall, until he faced the cleft and could give his attention to the nest.

Suddenly, screaming wildly with rage and fright, out from the dark cleft came the old mother-bird. Like a stone from a catapult she flung herself at Williams’s face.

Dismayed by the suddenness of the attack, Williams recoiled; his foot slipped from the wall, and his body spun round and out of reach as the huge bird went past him. He did not escape altogether scathless, for one claw, like a knife blade, cut across his cheek, and in an instant the blood was flowing from a cut half an inch deep.

Only a few yards did the old eagle fly; then she wheeled and, with the speed of an arrow, shot once more at the man hanging at the end of the rope before her nest.

This time Williams braced himself and, with his stout stick ready in his right hand, awaited the onslaught of the big bird. His left hand grasped the rope.

The eagle struck Williams on the head with her wing, and at the same moment Williams lashed at the bird with his stick. Such was the fury and strength of the creature, however, that the stick flew from Williams’s hand and went whirling through space to the bottom of the canyon, far below.

Again the eagle turned sharply and swooped down on the man, now left defenceless, with only a single bare hand to fight against the infuriated mother-bird’s sharp claws, powerful beak, and mighty wings.

Pecking, clawing, and striking stunning blows with her terrible wings, the big bird beat the air in front of Williams’s face, holding her position and tearing savagely at the head and face of the would be despoiler of her home. Her screams were incessant.
