"How do you know he is?" challenged Dunfin.

"For some time past there has been weeping and wailing amongst the sea gulls and wild ducks on the island. Every morning at daybreak a strange bird of prey comes and carries off one of them."

"What kind of a bird is it?" asked Dunfin.

"We don't know," replied the sister. "One of his kind has never before been seen on the island, and, strange to say, he has never attacked one of us geese. But now my intended has made up his mind to challenge him to-morrow morning, and drive him away."

"Oh, I hope he'll succeed!" said Dunfin.

"I hardly think he will," returned the sister. "If my goosey-gander were as big and strong as yours, I should have hope."

"Do you wish me to ask Morten Goosey-Gander to meet the strange bird?" asked Dunfin.

"Indeed, I do!" exclaimed Prettywing excitedly. "You couldn't render me a greater service."

The next morning the goosey-gander was up before the sun. He stationed himself on the highest point of the island and peered in all directions. Presently he saw a big, dark bird coming from the west. His wings were exceedingly large, and it was easy to tell that he was an eagle. The goosey-gander had not expected a more dangerous adversary than an owl, and how he understood that he could not escape this encounter with his life. But it did not occur to him to avoid a struggle with a bird who was many times stronger than himself.

The great bird swooped down on a sea gull and dug his talons into it. Before the eagle could spread his wings, Morten Goosey-Gander rushed up to him. "Drop that!" he shouted, "and don't come here again or you'll have me to deal with!" "What kind of a lunatic are you?" said the eagle. "It's lucky for you that I never fight with geese, or you would soon be done for!"
