“Yes,” said Edred, “and you’ve got to be nice to me for a whole day, or it’s no use my believing.”

“Aren’t I generally nice?” the girl pleaded, and her lips trembled.

“Yes,” said her brother. “Yes, Lady Arden; and now I’m going to be nice, too. And where shall we look for the door?”

This problem occupied them till tea-time. After tea they decided to paint—with the new paint-box and the beautiful new brushes. Elfrida wanted to paint Mr. Millar’s illustrations in “The Amulet,” and Edred wanted to paint them, too. This could not be, as you will see if you have the book. Edred contended that they were his paints. Elfrida reminded him that it was her book. The heated discussion that followed ended quite suddenly and breathlessly.

I wouldn’t be a selfish pig,” said Edred.

“No more would I,” said Elfrida. “Oh, Edred, is this being nice to each other for twenty-four hours?”

“Oh,” said Edred. “Yes—well—all right. Never mind. We’ll begin again to-morrow.”

But it is much more difficult than you would think to be really nice to your brother or sister for a whole day. Three days passed before the two Ardens could succeed in this seemingly so simple thing. The days were not dull ones at all. There were beautiful things in them that I wish I had time to tell you about—such as climbings and discoveries and books with pictures, and a bureau with a secret drawer. It had nothing in it but a farthing and a bit of red tape—secret drawers never have—but it was a very nice secret drawer for all that.

And at last a day came when each held its temper with a strong bit. They began by being very polite to each other, and presently it grew to seem like a game.

“Let’s call each other Lord and Lady Arden all the time, and pretend that we’re no relation,” said Elfrida. And really that helped tremendously. It is wonderful how much more polite you can be to outsiders than you can to your relations, who are, when all’s said and done, the people you really love.
