ding the presence of the light, and the absence of all
noise, such as would be caused by the murderer in leaving the room and
going down stairs, the impression of this tragic vision upon her mind
was not to be dismissed with a "Pshaw!"

Pet would have derived much relief from opening the door and looking in,
and seeing, with her own waking eyes, that her father was alive, at his
usual seat in the corner. She placed her hand upon the latch.

But then she remembered how her father had laughed at her, two or three
times before, when she was a younger girl, and not so wise as now, and
had rushed into his room screaming with fright from a nightmare. She
prided herself on having outgrown childish fears.

She also remembered that her father had told her, two days before, that
he was engaged in the most difficult mathematical calculations, day and
night, and, kissing her, had playfully said that she must not
disturb him.

"He is thinking over his problems now," thought little Pet. "Dear
father! I _do_ wish he would give up that hateful machine. It will be
the death of him. But he said I must not disturb him, and I will not.
Mr. Wilkeson must have gone home a long time ago; and dear father is
thinking, as he calls it, with his hand on his forehead, in the old
corner. Let me take one little peep through the keyhole, and go to
bed again."

Pet stooped, and looked through the keyhole. Within her range were the
chair where Marcus Wilkeson had sat that evening, and the nail
where--with bachelor-like precision--he always hung his hat. Neither
Marcus Wilkeson nor his hat were in their accustomed, places. "What
silly things these dreams are!" thought little Pet. The keyhole did not
command the corner of the room where the machine stood, and where the
inventor pondered and toiled; but Pet felt as certain that he was there,
coaxing thoughts out of his pale brow with that habitual caress of the
hand, as if she had seen him.

"Good night, dear father," she whispered, softly. "May Heaven watch over
your labors, and keep you from all harm."

With this pious prayer, she slid into her warm nest. But, before
adjusting her limbs for sleep, she threw off a portion of the heavy
blankets which had weighed upon her, and was soon sound asleep, and
dreaming of a garden in which all the roses were beautiful new bonnets.

Still the moon played her ghastly metamorphoses in the little chamber.
And the figures on the carpet and the figures on the c
