Jack was just a mischievous schoolboy, with protruding ears and twinkling eyes. One can see a score like him any day, marching, marching along the street with satchels of books; but his twin sister had a more striking personality. Jill was a mystery to her relations and friends. She had ordinary brown hair, and not too much of that, light blue eyes with indifferent lashes, a nose a shade more impertinent than Betty's own, a big mouth, and a powdering of freckles under her eyes; yet with those very ordinary equipments she managed to rank as a beauty among her schoolmates, and to attract more admiration than is vouchsafed to many people whose features might have been turned out of a classic mould. Betty used to ponder wistfully over the secret of Jill's charm, and think it hard lines that it had not been given to herself, who would have cared for it so much more. Jill didn't care a pin how she looked. She wanted to "have fun," to invite Nora Bruce to tea as often as possible, to buy a constant supply of a special sort of almond toffee which was offered for sale at a shop which she passed on the way to school, to be a first-form girl and have one of the new desks, and, incidentally, to pass the Cambridge examination if it could be done without too much "fag." She put on her clothes any way, did her hair in the twinkling of an eye, and the effect was uniformly charming. "If she's untidy, she's picturesque; if I'm untidy, I'm a fright. It's mean!" soliloquised Betty discontentedly. Every day she lived she was the more convinced that the world was topsy-turvy, and that she herself was the only person who was competent to set it to rights. Pam was just Pam; like herself, and no one else in the world. A dear little, wide-eyed, pointed-chinned kitten, everybody's tease, and pet, and conscience all in one, for those clear child eyes seemed to see through all pretences, and what she thought she put into words without a shadow of fear or hesitation. It was a very plain, almost a frugal, repast, but the table looked cheerful and pretty with the pink-shaded lamp in the centre, surrounded by the four little bowls of flowers which it was one of Betty's duties to keep fresh, and there was no lack of lively conversation. Mrs Trevor had had a trying day, and several of her worries must of necessity be discussed with her husband later on, but she would allow no hint of them to escape until he had been fed and rested, and in the same manner all the children searched their memories for the pleasantest event which they had experienced to retail for his benefit. "I was top to-day, father," Jack announced proudly; "answered every single question in Latin, and read off my translation like a book. If I liked to stew, I believe I could lick Johnston all the time. He was pretty sick at having to go down; looked as glum as an old owl for the rest of the morning."
