As has already been stated, Betty's pretty little bed was placed between Sylvia's and Hetty's; and now, as she slept, the two younger girls bent across, clasped hands, and looked down at her small white face. They could just get a glimmer of that face in the moonlight, which happened to be shining brilliantly through the three big windows. All of a sudden, Sylvia crept very softly out of bed, and, running round to Hester's side, whispered to her, "What is the matter?" "I don't know," replied Hester. "But something is," remarked Sylvia. "Yes, something is," said Hester. "Best not worry her." Sylvia nodded and returned to her own bed. On the following morning, however, all Betty's apparent low spirits had vanished. She was in that wild state of hilarity when she seemed to carry all before her. Her sisters could not help laughing every time Betty opened her lips, and it was the same during recess. When many girls clustered round her with their gay jokes, they became convulsed with laughter at her comic replies. It was arranged by Mrs. Haddo that Betty and her two sisters were to start for the Mileses' farm at three o'clock exactly. It would not take them more than half an hour to walk there. Mrs. Miles was requested to give them tea not later than four o'clock, and they were to be called for at half-past four. Thus they would be back at Haddo Court about five. "Only two hours!" thought Betty to herself. "But one can get a great deal of pleasure into two hours." Betty felt highly excited. Her sisters' delight at being able to go failed to interest her. As a rule, with all her fun and nonsense and hilarity, Betty possessed an abundance of self-control. But to-day she seemed to have lost it. The very staid-looking maid, Harris by name, who accompanied them, could scarcely keep pace with the Vivian girls. They ran, they shouted, they laughed. When they were about half-way to the Mileses' farm they came to a piece of common which had not yet been inclosed. The day was dry and comparatively warm, and the grass on the common was green, owing to the recent rains. "Harris," said Betty, turning to the maid, "would you like to see some Catharine wheels?" Harris stared in some amazement at the young lady. "Come along, girls, do!" said Betty. "Harris must have fun as well as the rest of us. You like fun, don't you Harris?" "Love it, miss!" said Harris. "Well, then, here goes!" said Betty. "Harris, please hold our hats." The next instant the three were turning somersaults on the green grass of the common, to the unbounded amazement of the maid, who felt quite shocked, and shouted to the young ladies to come back and behave themselves. Betty stopped at once when she heard the pleading note in Harris's voice. "You hadn't ought to have done it," said Harris; "and if my missis was to know! Oh, what shows you all three do look! Now, let me put your hats on tidy-like. There, that's better!"
