Miss Burtis put on very grand airs, considered herself, for some mysterious reason, quite superior to her companions, and also to her teachers, and made more fuss about her board and accommodations than all of the rest of the girls put together. She had begun by being very haughty toward Rhoda and declaring openly in her hearing that Miss Hardy had insulted all the other pupils by taking a common servant-girl into the school. She seemed to conceive a great aversion to Rhoda, and made no hesitation in saying that Miss Hardy had placed her in the school as a spy on the other girls. Rhoda, on her part, went quietly on her way, working hard at her lessons, happy in the musical instructions of a first-rate professor, and in the companionship of Isa, over whom she watched more like a mother over a child than one girl over another. It was soon discovered that she was equally handy and obliging in managing a boat, beginning a piece of crochet-work, or setting to rights a confused bit of embroidery; and henceforth no rowing- or sewing-party was complete without Rhoda Thurston. This being the case, Rhoda troubled herself very little about Miss Burtis and her airs. On a sudden Miss Burtis changed her tactics, and became as polite to Rhoda as she had formerly been rude. One day, as Rhoda was going out on an errand for Miss Hardy, taking Isa, with her, they met Miss Burtis in the hall. "Oh, girls, are you going out?" said she. "Will you just drop this letter in the post-office for me? I want it to go by the early mail, and I forgot to send it by Miss Hood." "Certainly," said Rhoda, taking the letter. "Come, Isa, I want to find Miss Hardy and ask her about this wool." "But you mustn't let Miss Hardy see the letter. You know," said Miss Burtis, in alarm, "she makes no end of fuss if the girls send letters on the sly. This is only to my cousin, but she is such an old maid she never will believe that." "Excuse me, Caroline, but I can't do anything in that way," said Rhoda, handing her back the letter; "I don't like doing things 'on the sly,' as you say." "But what harm is it, you goose? The letter is only to my cousin." "If it is no harm, why don't you want Aunt Harriet to know?" asked Isa. "Just as though one wanted to publish in the newspaper all that one did!" "Letting Aunt Harriet know isn't publishing in the newspaper," said Isa. "Really and truly, Caroline, I can't do it," said Rhoda. "If you will ask Miss Hardy—" "Well, I sha'n't ask Miss Hardy, so there!" answered Caroline, pettishly, snatching the letter from Rhoda's hand. "For my part, I don't think a servant-girl need be above doing an errand. You would have been glad to do it and get paid for it three months ago, I dare say; but I suppose, as you are a charity girl, you think you must be extra particular." "That is it exactly," said Rhoda. "Come, Isa, we shall be late."
