so swiftly, that she just could not contain her eagerness to beat somebody else to it.

Well, the laugh that followed also was of the nature of an explosion. And it was on poor Katherine quite as much as on Earl, who had tripped up on an adjective in place of an adverb. The girl's eagerness was so evident that it struck everybody as funnier than the boy's mistake in grammar. Anyway, she recovered quite smartly and followed up her attack with this pert addendum as the laughter subsided:

"You evidently don't do your lessons thorough-ly." The emphasis on the "-ly" was so pronounced, almost spasmodic, as to bring forth another laughing applause.

This exchange of repartee took place in the large school auditorium, to which all repaired as soon as the outdoor exercises had been finished.

The program of the evening was punctuated by interruptions of this kind every now and then. Of course, the fun-makers waited for suitable opportunities to spring their "quips and cranks," so that no merited interest in the doing could be lost. And none of it was lost. The presence of the bold invaders seemed to add zest to the most routine of the Camp Fire performances, and when all was over everybody was agreed that there had not been a dull minute during the whole evening.

At the close of the Camp Fire Girls' program the 150 Boy Scouts arose and, with heroic unison of voices peculiar to much practice in the delivery of school yells, they chanted a clever parody of Wo-he-lo Cheer, a Boy Scout's compliment to the Camp Fire Girls, and then marched out of the auditorium and away toward the interurban line, where their chartered train was waiting for them, and all the while they continued the chant with variations of the words, the rhythmic drive of their voices pulsing back to the Institute, but becoming fainter and more faint until at last the sound was lost with the speeding away of the trolley train in the distance.

CHAPTER III.

THE SKULL AND CROSS-BONES.

If Marion Stanlock, "High Peak" in the trait and a torch bearer, had read one of two letters, signed with a "skull and cross-bones," which she found lying on the desk in her room after the adjournment of the Grand Council Fire, doubtless there would have been an interruption, and probably a change, in the holiday program of the Flamingo Camp Fire. She saw the letters lying there and under ordinary circumstances would have torn them open and read them, however hastily, before retiring. But on this occasion she was rather tired, owing to the activities and the excitement of the day and evening. Moreover, she realized that she could not hope for anything but a wearisome journey to Hollyhill on the following day unless she refreshed herself with as many hours sleep as possible before train time.

So she merely glanced at the superscriptions on the envelopes to see if the letters were from any of her relatives or friends, and, failing to recognize either of them, she put them into her handbag, intending to read them at the first opportunity next morning. Then she went to bed and fell asleep almost instantly.

Marion was awakened in the morning by her roommate, Helen Nash, who had quietly arisen half an hour earlier. The latter was almost ready for breakfast when she woke her friend from a sleep that promised to continue several hours longer unless interrupted. She had turned on the electric light and was standing before the glass combing her hair. Marion glanced at the clock to see what time it was, but the face was turned away from her and the light in the room made it impossible for her to observe through the window shades that day was just breaking.

"What time is it, Helen?" she asked. "Did the alarm go off? I didn't hear it. What waked you up?"

Helen did not answer at once. For a moment or two her manner seemed to indicate that she did not hear the questions of the girl in bed. Then, as if suddenly rescuing her mind from thoughts that appealed to have carried her away into some far distant abstraction, she replied thus, in a series of disconnected utterances:

"No, the alarm didn't go off—a—Marion. I got up at 6 o'clock. I turned the alarm off. It is 6:30 now. I don't know what woke me. I just woke up."

Marion arose, wondering at the peculiar manner of her roommate and the strained, almost convulsive, tone of her voice. She asked no further questions, but proceeded with her dressing and preparation for breakfast. For the time being, she forgot all about the two letters in her handbag that lay on her dresser.

In some respects Helen was a peculiar girl. If her speech and action had been characterized with more vim, vigor and imagination, doubtlessly she would generally have been known as a pretty girl. As it was, her features were regular, her complexion fair, her eyes blue, and her hair a light brown. Marion thought her pretty, but Marion had associated with her intimately for two or three years, and had discovered qualities in her that mere acquaintances could never have discovered. She had found Helen apparently to be possessed of a strong, direct conception of integrity, never vacillating in manner or sympathies. Moreover, she exhibited a quiet, unwavering capability in her work that always commanded the respect, and occasionally the admiration, of both classmates and teachers.

Not only was Helen quiet of disposition, but strangely secretive on certain subjects. For instance, she seldom said anything about her home or relatives. She lived in Villa Park, a small town midway between Westmoreland and Hollyhill. Her father was dead, and, when not at school, she had lived with her mother; these two, so far as Marion knew, constituting the entire family.

Marion had visited her home, and there found the mother and daughter apparently in moderate circumstances. Naturally, she had wondered a little that Mrs. Nash should be able to support her daughter at a private school, even though that institution made a specialty of teaching rich men's daughters how to be useful and economical, but the reason why had never been explained to her. Helen got her remittances from home regularly, and seemed to have no particular cause to worry about finances. She had spent parts of two vacations at the Stanlock home and there conducted herself as if quite naturally able to fit in with luxurious surroundings and large accommodations.

Only a few days before the Christmas holidays, something had occurred that emphasized Helen's secretive peculiarity to such an extent that Marion was considerably provoked and just a little mystified. A young man, somewhere about 25 or 27 years old, fairly well but not expensively dressed, and bearing the appearance of one who had seen a good deal of the rough side of life, called at the Institute and asked for Miss Nash. He was ushered into the reception room and Helen was summoned. One of the girls who witnessed the meeting told some of her friends that Miss Nash was evidently much surprised, if not unpleasantly disturbed, when she recognized her caller. Immediately she put on a coat and hat and she and the young man went out. An hour later she returned alone, and to no one did she utter a word relative to the stranger's visit, not even to her roommate, who had passed them in the hall as they were going out.

Helen Nash was a member of the Flamingo Camp Fire and accompanied the other members on their vacation trip to the mountain mining district. The other eleven who boarded the train with Marion, the holiday hostess, were Ruth Hazelton, Ethel Zimmerman, Ernestine Johanson, Hazel Edwards, Azalia Atwood, Harriet Newcomb, Estelle Adler, Julietta Hyde, Marie Crismore, Katherine Crane, and Violet Munday.

Miss Ladd, the Guardian, also was one of Marion's invited guests. The party took possession of one end of the parlor car, which, fortunately, was almost empty before they
