These fortunate girls attended a beautiful school. That is, the building was beautiful. It stood right in the middle of a great big grassy block, entirely surrounded, as Bettie put it, by street, which of course added greatly to its dignity. It was built of "raindrop" sandstone, a most interesting building material because no two blocks were alike and also because each stone looked as if it had just been sprinkled with big, spattering drops of rain. It was hard when looking at it to believe that it wasn't raining, and certain naughty youngsters delighted in fooling new teachers by pointing out the deceiving drops that flecked the balustrade. Perhaps even the grass was fooled by this semblance to showers for, in summer time, it grew so thriftily that no one had to be warned to "Keep off," so a great many little people frolicked in the schoolyard even during vacation. Of course the Dandelion Cottagers were not in the same classes in school. Jean, being the oldest, the most sedate and the most studious, was almost through the eighth grade. Marjory, being naturally very bright and also moderately industrious, was in the seventh. Mabel and Bettie were not exactly anywhere. You see, Bettie had had to stay out so often to keep the next to the youngest Tucker baby from falling downstairs, that naturally she had dropped behind all the classes that she had ever started with; and Mabel--of course Mabel _meant_ well, but when she studied at all it was usually the lesson for some other day; for this blundering maiden never _could_ remember which was the right page. But one day she happened by some lucky accident to stumble upon the right one, and on that solitary occasion she recited so very brilliantly that Miss Bonner and all the pupils dropped their books to listen in astonishment, and Mabel was marked one hundred. But in spite of this high mark in good black ink (if one stood less than seventy-five red ink was employed) the thing did not happen again that fall because Mabel was too busy bringing up Rosa Marie to study even the wrong lesson. However, she was exceedingly fond of pretty Miss Bonner and, having learned the exact date of that young woman's birthday, hoped to appease her by a gift to be paid for by contributions from all the pupils in Miss Bonner's room. Mabel herself received and cared for the slowly accumulating funds, and the little brown purse was becoming almost as weighty a responsibility as Rosa Marie had been. Sometimes it rested in Mabel's untrustworthy pocket, sometimes in her rather untidy desk, sometimes under her pillow in her own room at home. One day Mrs. Bennett found it there. "Why, Mabel!" she exclaimed. "Where did all this money come from? I know _you_ don't possess any." "It's the M. B. B. P. F.," responded Mabel, who was brushing her hair with evident enjoyment and two very handsome military brushes. "I guess I'd better put it in my pocket." "The what?" asked puzzled Mrs. Bennett.
