[Illustration: "Left the room with such uncompromising hauteur ... that her aunt again exploded"] The fact that she had irretrievably lost one credit through tardiness set Sissy's lips in a tight line of determination to guard jealously every one of the ninety-and-nine left to her. At recess she remained at her desk studying her geography with an intensity of purpose that made her rivals' hearts quake. She sat at the teacher's desk--lifted to this almost regal eminence by his fondness for her petulant ways as well as because of that quality of leadership which made Sissy her fellows' spokeswoman. Hers was the privilege of using the master's pencils, sharpened to a fineness that made neatness a dissipation instead of a task. It was she, of course, who originated the decorative style of arithmetic-paper much in vogue, on which each example was penned off in an inclosure fenced by alternating vertical and horizontal double hyphens. But a queer, conscientious sense of the responsibilities of power and place modified Sissy's rapturous delight in her position, so that she kept it despite a fiercely jealous class-spirit developed by a strict credit-system, by the emulative temper which the rarefied atmosphere of the little mining town fostered, and by a young master just out of college who looked upon his teaching as a temporary adventure, much as a Japanese gentleman regards domestic service. It was in her capacity of class representative that the master had consulted Sissy upon the limits to be observed in the forthcoming public oral examination in geography. And she had enlightened him as to what would be considered quite "fair." This treaty, into which she entered with the seriousness of an ambassador to an unfriendly power arranging a settlement of a disputed question, had a character so sacred in her eyes that its violation by the master in the course of the afternoon came upon her like a blow. "Cecilia Madigan," asked the master, "what is the highest mountain in the world?" Sissy rose. The imposing array of visitors in school faded out of her horizon. All she could see was the eyes of her schoolmates turned in accusatory horror upon her. They suspected her of betraying them; of using her elevated position to hand down untrustworthy information. "Please, Mr. Garvan," she said in tones more of sorrow than of anger, skilfully showing her knowledge of the answer while denying his right to it, "that question isn't on the map of Africa." [Illustration: "'Please, Mr. Garvan,' she said"] A flush of annoyance mounted to the young master's forehead. Out of the corner of her eye Sissy saw the preliminary twitch of the corners of his lips that served the class for a danger-signal. "What is the highest mountain, Cecilia?" he repeated sternly.
