"Yes, but," said Dolly, "then one of us would have to be wrong, and I'd rather go on fancying that somehow neither of us was wrong."

"That's rubbish," said Max, "it couldn't be."

"Listen," said mamma; "promise me that neither of you will look out of the window to-morrow morning before you see me. Then if it is really a fine mild day, the doctor says you may both go a little walk."

"Oh, how nice!" interrupted the little prisoners. "And I will take you myself," their mother went on. "Immediately after your dinner—about two o'clock will be the best time. And we will see if we can't settle the question of the thir—no, I had better not say how many—of the little black pigs, in a satisfactory way."

Mamma smiled at the children—her smile was very nice, but there was a little sparkle of mischief in her eyes too. And I may tell you, in confidence, though she had not said so to Max and Dolly, that that afternoon she had passed Farmer Wilder's when she was out walking with their father, and had stood at the gate of the very field which the children saw from the nursery window, where the little black pigs were gambolling about. And Farmer Wilder had happened to come by himself, and he and his landlord—the children's father, you understand—had had a little talk about pigs in general, and these piglings in particular. And so mamma knew more about them than Max and Dolly had any idea of.

How pleased they were when they woke the next morning to think that they were really going out for a little walk—out into the sweet fresh air again, after all these weary dreary weeks in the house. And it was really a very nice day; there was more sunshine than had been seen for some time, so that at two o'clock the children were all ready—wrapped up and eager to start when their mother peeped into the nursery to call them.

At first the feeling of being out again was so delicious it almost seemed to take away their breath, and they could not think of anything else. But after a few minutes they quieted down a little, and walked on with their mother, one at each side.

"We kept our promise, mamma," said Dolly, "we didn't look out of our windows at all this morning. Nurse let us look out of the night nursery one for a little—it's turned the other way, so we couldn't see the pigs."
