monkey-wrench and the pie, I'll leave on the foot of her bed, so she'll
know she wasn't dreaming."

"What if she screams?" asked Priscilla.

"She won't scream. She loves ghosts--especially Cousin Susan. She said
to-night she'd be glad to meet her."

"But what if she does scream?" persisted Priscilla.

"Oh, that's easy! I'll dash back and pop into bed. Before anybody wakes,
I'll be sound asleep."

They made a reconnoitering excursion into the empty corridors to make
sure that all was quiet. Only regular breathing issued from open doors.
Evalina fortunately lived in a single, but unfortunately, it was at the
extreme end of the East Wing in the opposite corner of the building from
Patty's own domicile. Conny and Priscilla, in bedroom slippers and
kimonos, tiptoed after Patty as she took her flight down the length of
the Alley. She sailed back and forth and waved her wings in the
moonlight that streamed through the skylight in the central hall. The
two spectators clung together and shivered delightedly. In spite of
having been behind the scenes and assisted at the make-up, they received
a distinct sensation--what it would be to one suddenly wakened from
sleep, to a believer in ghosts, they were a bit apprehensive to
consider. At the entrance to the East Wing, they handed Patty her pie

room, where she took up a central position in a patch of moonlight. A
few sepulchral "Comes!" brought no response. Evalina was a sound
sleeper.

Patty shook the foot of the bed. The sleeper stirred slightly but slept
on. This was annoying. The ghost had no mind to make noise enough to
disturb the neighbors. She laid the pie and the monkey-wrench on the
counterpane, and shook the bed again, with the insistence of an
earthquake. As she was endeavoring to resume her properties, Evalina
sat up and clutched the bed clothes about her neck with a frenzied jerk.
Patty just had time to save the pie--the monkey-wrench went to the floor
with a crash; and the crash, to Patty's startled senses, was echoed and
intensified from far down the hall. She had no chance to wave her wings
or murmur, "Come." Evalina did not wait for her cue. She opened her
mouth as wide as it wou
