Sally was very glad that Jane was gone from his seat beside her, for he had almost convulsed her by his pranks on countless occasions and had very nearly made her disgrace herself by laughing aloud. She had fears, however, still; for Jane's new desk was between the principal and the classes that he was hearing, and was on the floor, while the principal's desk was on the platform. Jane, therefore, was, in a measure, concealed from the view of the astute MacDalie, but in full view of the class, which occupied benches a few feet behind him. Moreover, the desks on either side of Jane's--there were three of them in a row, of which Jane occupied the middle one--were occupied, respectively, by the Carlings. The Carlings always occupied those desks. They had got to feeling a sort of proprietorship in them. Jane, however, knew too much to continue his mischief on that day. He was filled to the brim with it, that was all, and it was only a question how long before it would run over. Sally was glad when the bell called her to a class downstairs; and she sat as if in a trance and watched Jane Spencer gravely fishing in the aquarium tank with a bent pin on the end of a thread. He kept on fishing all through the class hour, unhindered. The single little fish in the tank tugged at the pin occasionally, without result; and, when the bell sounded again, Jane folded up his line and put it in his book. "No luck," he observed, bowing to the teacher. "Too bad!" said the teacher sympathetically. "Yes, isn't it?" said Jane; and he withdrew in good order, leaving the teacher smiling to himself. What was he smiling at, I wonder? Jane never descended to such behavior as sitting with his feet in his desk, as Oliver Pilcher did. No doubt he considered it undignified and generally bad form, which unquestionably it was. Moreover he would thereby run the risk of getting caught in a situation which he regarded as unprofessional. Oliver Pilcher was caught several times, for it is somewhat difficult to get one's feet out of one's desk as quickly as is necessary to avoid that humiliation. If you do not believe it, try it.
