"The real gist of the matter," said Dorrie, wrinkling her brows anxiously, "is whether I'm to put them in the tennis list. They play uncommonly well."

"Oh, it wouldn't be fair to let new girls represent the school!"

"You think so? On the other hand, the school must win by hook or by crook."

"Well, I don't think it would do to make either of them a champion, putting them above the heads of those who have been here for years."

"It's a difficult question, certainly."

"Difficult? Not at all; I think it's conclusive!" snapped Viola rather sharply. "Those who are trained in Aireyholme methods are best fitted to represent Aireyholme. There can't be two opinions about it."

There was certainly some occasion for the rather jealous attitude which the monitresses were inclined to adopt towards Katrine. By the arrangement which her mother had made with Mrs. Franklin, she was really more in the position of the old-fashioned "parlour boarder" than of an ordinary pupil. She had been placed in the Sixth Form, but took less than half the classes, the rest of her time being devoted to art lessons. While others were drudging away at Latin translation, or racking their brains over mathematical problems, she was seated in the studio, blissfully painting flowers; or, greater luck still, sallying forth with paint-box and easel to sketch from nature. As the studio was the favourite haunt of most of the seniors, these special privileges were the envy of the school. Nan Bethell and Gladwin Riley, in particular, hitherto the Aireyholme art stars, felt their noses much put out of joint, and were injured that their mothers had not made a like arrangement on their behalf. They went so far as to petition Mrs. Franklin for a similar exemption from certain lessons in favour of painting. But the Principal was adamant; the Sixth was her own particular form, she was jealous of its reputation, and by no means disposed to excuse members, whom she had been coaching for months, the credit which they ought to gain for the school in the examination lists. Though art was a pet hobby at Aireyholme, it must not be allowed to usurp the chief place, to the detriment of Mrs. Franklin's own subjects.

In the meantime Katrine, quite unaware of these difficulties, wore her picturesque painting apron for several hours daily, and revelled both in her work and in the companionship of her new teacher. Miss Aubrey was the greatest possible contrast to her sister, Mrs. Franklin. Instead of being tall, imposing, and masterful, she was small, slight, and gentle in manner. "A ducky little thing", most of the girls called her, and Katrine endorsed the general opinion. Miss Aubrey certainly would not have made a good head of the establishment; she was absent-minded, dreamy, and made no attempt to uphold discipline; but in her own department she was delightful. The pupils talked with impunity in her classes, but they nevertheless worked with an enthusiasm that many a stricter teacher might have failed to inspire. There was an artistic atmosphere about Miss Aubrey; she always seemed slightly in the clouds, as if she were busier observing the general picturesque effect of life than its particular details. In appearance she was pleasing, with soft grey eyes and smooth brown hair. It was the fashion at the school to call her pretty. The girls set her down as many years younger than Mrs. Franklin. The studio was, of course, her special domain at Aireyholme; she worked much there herself, and quite a collection of her pictures adorned the walls. The crisp, bold style of painting aroused Katrine's admiration, and made her long to try her skill at landscape-sketching. Miss Aubrey had kept her at a study of flowers until she could judge her capabilities; but at the end of the first week the mistress declared her ready for more advanced work.

"I am going into the village this morning to finish a picture of my own," she announced. "You and your sister may come with me, and I will start you both at a pretty little subject."

Gwethyn, whose time-table had been left to the entire discretion of Mrs. Franklin, was highly elated to find that she was to share some of Katrine's art privileges. She had never expected such luck, and rejoiced accordingly. The fact was that Miss Aubrey wished to continue her own sketch, and to settle Katrine at an easier subject a hundred yards farther down the street. She thought it might be unpleasant for the girl to sit alone, and that the sisters would be company for each other. She would be near enough to keep an eye on them, and to come and correct their drawings from time to time. Much encumbered, therefore, with camp-stools, easels, boards, paint-boxes, and other impedimenta, but feeling almost equal to full-blown artists, the Marsdens, to the wild envy of their less fortunate school-fellows, sallied forth with Miss Aubrey down to the village. Their teacher had chosen a very picturesque little bit for their first attempt—a charming black-and-white cottage, with an uneven red-tiled roof and an irregular, tumble-down chimney. She superintended them while they opened their camp-stools and fixed their easels, then showed them where the principal lines in their sketches ought to be placed.
