"Why," said Marjorie, suddenly, "both these children are asleep!"

"Mrs. Harrison said Totty would go to sleep," said Gladys. "I guess all babies go to sleep about this time in the morning. It seems too bad to wake them up to change their coats back again, but I think we ought to take Totty back, don't you?"

"Yes, I do. Suppose we leave the coats and caps as they are, and then afterward we can bring back Dotty's things and get Totty's."

"Here you are!" cried Lisa, coming to meet them at the front door.

"You're good little girls to mind the baby for me. I'll take her now, and I thank you much."

As Lisa spoke, she took hold of the Curtis carriage, which contained the Harrison baby.

"Ah, she's asleep, bless her heart!" she exclaimed, looking at the closed eyes, almost hidden by the white veil. "I'm glad she's getting a fine nap. Run along now with your own baby."

Partly confused by Lisa's quick and peremptory dismissal, and partly impelled by a sudden mischievous idea, Marjorie smiled a good-bye, and began trundling the other carriage toward the gate.

"Why, Midge!" whispered Gladys, aghast. "We've got the wrong baby! This is Dotty Curtis!"

"Keep still!" whispered Marjorie. "I know it. But it's a good joke on that snippy Lisa."

"She wasn't snippy."

"Yes, she was; she said 'Run along now, little girls,' after we've been helping her all the morning. She's going to let the baby stay asleep in the carriage, and she won't know it till she wakes up."

"Who won't? The baby?"

"No, Lisa. And then she'll be scared, and it will serve her right."

"But what about Mrs. Harrison? You don't want to scare her."

"That's just the thing," explained Marjorie. "I want to see if she'll know the difference in the babies. They say mothers can always tell their own children. Now we'll see."

"It's a great joke," said Gladys, giggling. "But suppose they never find it out, and the children live with their wrong mothers all their lives!"

"Don't be silly," said Marjorie.

CHAPTER XIII

A FAIR EXCHANGE?

Mrs. Maynard opened the front door just as the children approached with the baby-carriage.

"Come along, girlies!" she cried. "Marjorie, wheel the carriage right into the hall."

"The baby's asleep, Mother," said Midget, as she and Gladys brought the carriage over the door-sill.

"Oh, is she? Totty's asleep, Mildred," she called, in a stage whisper, to Mrs. Harrison, who was upstairs.

"I thought she would be," responded that lady. "Just throw back her veil, and leave her as she is. She often takes her nap in her carriage, and there's no use waking her."

Gently, Mrs. Maynard turned back the veil from the little sleeping face, and, as she had no thought of anything being wrong, she did not notice any difference in the baby features.

"Gladys, we'd like to have you stay to luncheon," she said. "So you and Midge run upstairs and tidy your curls at once." With demure steps, but with dancing eyes, the girls went upstairs.

"I'm afraid it's mischief," whispered Gladys to Marjorie, as she tied her hair-ribbon for her.

"No, it isn't!" declared Midge, stoutly. "It's only a joke, and it can't do any harm. Mother didn't know it was a different baby, and I don't believe Mrs. Harrison will know either."

Trim and tidy once more the two friends went downstairs.

As they were on the stairs they heard the sound of the telephone bell.

Mrs. Maynard answered it, and in a moment Gladys realized that her own mother was talking at the other end of the wire.

After a short conversation, Mrs. Maynard hung up the receiver, and said:

"Mrs. Fulton says that Mr. Fulton has come home quite unexpectedly and that they are going for an afternoon's motor ride. She wants both of you girls to go, but she says you must fly over there at once, as they're all ready to start. She tried to tell us sooner, but couldn't get a connection on the telephone."

"But we haven't had luncheon," said Marjorie, "and I'm fairly starving."

"They're taking luncheon with them," explained Mrs. Maynard. "And you must go at once, not to keep Mr. Fulton waiting. Of course, you needn't go if you don't want to, Midge."

"Oh, I do! I'm crazy to go! And luncheon in baskets is such fun! What shall I wear, Mother?"

"Go just as you are. That frock is quite clean. Put on your hat and coat, and I'll get a long veil for you."

Gladys had already run off home, and Marjorie was soon equipped and ready to follow.

As she flew out of the door, she remembered the joke about the babies.

"Oh, Mother, I've something to tell you!" she cried.

"Never mind now," said Mrs. Maynard, hurrying her off. "It will keep till you get back. And I hate to have you keep the Fultons waiting.

They're in haste to start. So kiss me, and run along."

Even as she spoke, d.i.c.k Fulton appeared, saying he had been sent to hurry Marjorie up; so taking d.i.c.k's hand, the two ran swiftly down the path to the gate. Mrs. Maynard watched Marjorie's flying feet, and after she was out of sight around the corner, the lady returned to the house.

With a glance at the sleeping child, she turned to Mrs. Harrison, who was just coming downstairs.

"Totty is sleeping sweetly," she said, "so come at once to luncheon, Mildred."

"In a moment, Helen. I think I'll take off her cap and coat; she'll be too warm."

"You'll waken her if you do."

"Oh, well, she'll drop right to sleep again; she always does. And anyway, it's time she had a drink of milk."
