them."

"By all means," said Bonnie. "Behold Sherlock Holmes and his friend Dr.
Watson about to solve the Mystery of the Shadowed Sophomore."

"You've saved my life," said Mildred, feelingly. "Don't forget. Right
after chapel, by the lake." She peered warily out through the branches.
"I've got to get the keys to the gymnasium, so the refreshments can be
put in during chapel. Do you see anybody lurking about? I guess I can
get off without being seen. Good-by"; and she sped away like a hunted
animal.

Bonnie looked after her and laughed. "'Youth is a great time, but
somewhat fussy,'" she quoted; and the two took their homeward way.

They found Patty, who was experiencing a periodical fit of studying,
immersed in dictionaries and grammars. It was under protest that she
allowed herself to be interrupted long enough to hear the story of their
proposed adventure.

"You babies!" she exclaimed. "Haven't you grown up yet? Don't you think
it's a little undignified for seniors--one might almost say alumnae--to
be kidnapping freshmen?"

"We're not kidnapping freshmen," Bonnie remonstrated; "we're teaching

"I wish to present you to Miss Henderson, one of our alumnae who is to
lecture to-night before the Archaeological Society. She has not been back
for several years, and wishes to see the new buildings. Have you time to
show her around the campus a little before the lecture begins?"

Patty bowed and murmured that she would be most happy, and cast an
agonized glance back at Cathy as she led the lecturer off. As they
strolled about, Patty poured out all the statistics she knew about the
various buildings, and Miss Henderson received them with exclamations of
delighted surprise. She was rather young and gushing for a Ph.D. and an
archaeologist, Patty decided, and she wondered desperately how she could
dispose of her and get back to "Beowulf" and Cathy.

They rounded the top of a little hil
