Just then two birds flew by, close together and perfect mates; and the cows raised their heads and "mooed" at the same time; and two men--also twins--came over the two hills along the two paths with two dinner-pails in their hands and entered the two houses. They were met at the doors by the two women, who kissed them exactly at the same time and helped them off with their coats with the same motions, and closed the two doors with two slams at the same instant.

Nerle laughed. "What sort of country have we got into?" he asked.

"Let us find out," replied the prince, and riding up to one of the houses he knocked on the door with the hilt of his sword.

Instantly the doors of both houses flew open, and both men appeared in the doorways. Both started back in amazement at sight of the strangers, and both women shrieked and both little boys began to cry. Both mothers boxed the children's ears, and both men gasped out:

"Who--who are you?"

Their voices were exactly alike, and their words were spoken in unison. Prince Marvel replied, courteously:

"We are two strangers who have strayed into your country. But I do not understand why our appearance should so terrify you."

"Why--you are singular! There is only half of each of you!" exclaimed the two men, together.

"Not so," said the prince, trying hard not to laugh in their faces. "We may be single, while you appear to be double; but each of us is perfect, nevertheless."

"Perfect! And only half of you!" cried the men. And again the two women, who were looking over their husbands' shoulders, screamed at sight of the strangers; and again the two boys, who were clinging to their mothers' dresses in the same positions, began to cry.
