Priscilla and Bonnie smiled appreciatively. It was not so long, after all, since they themselves were soph.o.m.ores, and they recalled their own tree ceremonies, when the freshmen had _not_ been cooped up.

"But the trouble is," pursued Mildred, "that it's more important for me to get there than any one else, because I have to dig the hole,--Peters is really going to dig it, you know; I just take out the first shovelful,--but I can't get there on account of that beastly scout. As soon as she saw me acting suspicious, she'd run and warn the cla.s.s."

"I see," said Bonnie; "but what have Priscilla and I to do with it?"

"Well," said Mildred, tentatively, "you're both pretty big, you know, and you're our sister cla.s.s, and you ought to help us."

"Certainly," acquiesced Bonnie; "but in just what way?"

"Well, my idea was this. If you would just stroll down by the lake after chapel, and loiter sort of inconspicuously among the trees, you know, I would come that way a little later, and then, when the detective person came along after me, you could just nab her and--"

"Chuck her in the lake?" asked Bonnie.

"No, of course not. Don't use any force. Just politely detain her till you hear us yelling--take her for a walk. She'd feel honored."

Bonnie laughed. The program struck her as entertaining. "I don't see anything very immoral in delaying a freshman who is going where she has no business to go. What do you say, Pris?"

"It's not exactly a Sunday-school excursion," acknowledged Priscilla, "but I don't see why it isn't as legitimate for us to play detective as for them."

"By all means," said Bonnie. "Behold Sherlock Holmes and his friend Dr.

Watson about to solve the Mystery of the Shadowed Soph.o.m.ore."

"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 them manners. It's my duty to protect my little cousin."

"You can come with us and help detect," said Priscilla, generously.

"Thank you," said Patty, loftily. "I haven't time to play with you children. Cathy Fair and I are going to do Old English to-night."

That evening, as Patty, keyed to the point of grappling with and throwing whole pages of "Beowulf," stood outside the chapel door waiting for Cathy to appear, the professor of Latin came out with a stranger.

"Oh, Miss Wyatt!" she exclaimed in a relieved tone, pouncing upon Patty.

"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 hill, and Miss Henderson exclaimed delightedly, "There is the lake, just as it used to be!"

Patty stifled a desire to remark that lakes had a habit of staying where they used to be, and asked politely if Miss Henderson would like to take a row.

Miss Henderson thought that it would be pleasant; but she had forgotten her watch, and was afraid there would not be time.

Patty glanced about vaguely for some further object of interest, and spied Mildred Connaught sauntering toward the lake. She had forgotten all about the Sherlock Holmes adventure, and she suddenly had an inspiration. Be it said to her credit that she hesitated a moment; but the lecturer's next remark led to her own undoing. She was murmuring something about feeling like a stranger, and wishing that she might know the students informally and see a little of the real college life.

"It would be a pity not to gratify her when I can do it so easily,"

Patty told herself; and she added out loud, "I am sure we have time for a little row, Miss Henderson. You walk on, and I will run back and get my watch; it won't take a minute."

"I wouldn't have you do that; it is too much trouble," remonstrated Miss Henderson.

"It's no trouble whatever," Patty protested kindly. "I can take a cross cut, and meet you at the little summer-house where the boats are moored.

It's straight down this path; you can't miss it. Just follow that girl over there"; and she darted away.

The lecturer gazed dubiously after her a moment, and then started on after the girl, who cast a look over her shoulder and quickened her pace. It was growing quite dusky under the trees, and the lecturer hurried on, trying to keep the girl in sight; but she unexpectedly turned a corner and disappeared, and at the same moment two strange girls suddenly dropped into the path, apparently from the tree-tops.

"Good evening," they said pleasantly. "Are you taking a walk?"

The lecturer started back with an exclamation of surprise; but as soon as she could regain her composure, she replied politely that she was strolling about and looking at the campus.

"Perhaps you would like to stroll with us?" they inquired.

"Thank you, you are very kind; but I have an engagement to row with one of the students."

Priscilla and Bonnie exchanged delighted glances. They had evidently caught a resourceful young person.

"Oh, no; it's too late for a row. You might get malaria," Priscilla remonstrated. "Come and sit on the fence with us and admire the stars; it's a lovely night."

The lecturer cast an alarmed glance toward the fence, which appeared to have an unusually narrow top rail. "You are very kind," she stammered, "but I really can't stop. The girl will be waiting."

"Who is the girl?" they inquired.

"I don't know that I remember her name."

"Mildred Connaught?" Bonnie suggested.

"No; I don't think that is it, but I really can't say. I have only just met her."

Miss Henderson was growing more and more puzzled. In her day the students had not been in the habit of way-laying strangers with invitations to go walking and sit on fences.

"Ah, _do_ stay with us," Bonnie begged, laying a hand on her arm. "We're lonely and want some one to talk to--we'll tell you a secret if you do."

"I am sorry," Miss Henderson murmured confusedly, "but--"

"We'll tell you the secret anyway," said Bonnie, generously, "and I'm sure you'll be interested. The soph.o.m.ores are going to have their tree ceremonies to-night!"

"And you know," Priscilla broke in, "that the freshmen really ought to attend them too--it doesn't matter if they aren't invited. But where do you suppose the freshmen are to-night? They're attending a foolish little lecture on the Roman Forum."

"And though we don't wish to seem insistent," Bonnie added, "we should really like to have your company until the lecture is over."

"Until the lecture is over! But I am the lecturer," gasped Miss Henderson.
