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

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, s
