“Now a chase!” cried François, “yonder comes the big robber!”

With some excitement of feeling, the whole party watched the movements of the birds. A few strokes of the eagle's wing brought him near; but the osprey had already heard his scream, and knowing it was no use carrying the fish to his nest, turned away from it, and rose spirally upward, in the hope of escaping in that direction. The eagle followed, beating the air with his broad pinions, as he soared after. Close behind him went the female osprey, uttering wild screams, flapping her wings against his very beak, and endeavouring to distract his attention from the chase. It was to no purpose, however, as the eagle full well knew her object, and disregarding her impotent attempts, kept on in steady flight after her mate. This continued until the birds had reached a high elevation, and the ospreys, from their less bulk, were nearly out of sight. But the voyageurs could see that the eagle was on the point of overtaking the one that carried the fish.

THE OSPREY AND WHITE-HEADED EAGLE.

Presently, a glittering object dropped down from the heavens, and fell with a plunge upon the water. It was the fish, and almost at the same instant was heard the “whish!” of the eagle, as the great bird shot after it. Before reaching the surface, however, his white tail and wings were seen to spread suddenly, checking his downward course; and then, with a scream of disappointment, he flew off in a horizontal direction, and alit upon the same tree from which he had taken his departure. In a minute after the ospreys came shooting down, in a diagonal line, to their nest; and, having arrived there, a loud and apparently angry consultation was carried on for some time, in which the young birds bore as noisy a part as either of their parents.

“It's a wonder,” said Lucien, “the eagle missed the fish—he rarely does. The impetus which he can give his body enables him to overtake a falling object before it can reach the earth. Perhaps the female osprey was in his way, and hindered him.

“But why did he not pick it up in the water?” demanded François.

“Because it went to the bottom, and he could not reach it—that's clear.”

It was Basil who made answer, and the reason he assigned was the true one.

“It's too bad,” said François, “that the osprey, not half so big a bird, must support this great robber-tyrant by his industry.”
