But just at that moment a strange thing happened. The little casement window burst open with a bang, and a blast of cold sharp wind dashed into the room, upsetting a chair, scattering Gratian's clothes, neatly laid together in a little heap, and flinging itself on the bed with a whirl, so that the coverlet took to playing antics in its turn, and the blankets no doubt would have followed its example had Gratian not clutched at them. But all his comfort was destroyed—no possibility of feeling warm and snug with the window open and all this uproar going on. Gratian sprang up in a rage, and ran to the window. He shut it again easily enough.

"I can't think what made it fly open," he said to himself; "there was no wind in the night, and it never burst open before."

He stood shivering and undecided. Now that the window was shut, bed looked very comfortable again.

"I'll just get in for five minutes," he said to himself; "I'm so shivering cold with that wind, I shan't get warm all day."

He turned to the bed, but just as one little foot was raised to get in, lo and behold, a rattle and bang, and again the window burst open! Gratian flew back, it shut obediently as before. But he was now thoroughly awakened and alert. There was no good going back to bed if he was to be blown out of it in this fashion, and Gratian set to to dress himself, though in a rather surly mood, and keeping an eye on the rebellious window the while. But the window behaved quite well—it showed no signs of bursting open, it did not even rattle! and Gratian was ready in good time after all.

"You look cold, my boy," said his mother, when he was seated at table and eating his breakfast.

"The wind blew my window open twice, and it made my room very cold," he replied rather dolefully.

"Blew your window open? That's strange," said his father. "The wind's not in the east this morning, and it's only an east wind that could burst in your window. You can't have shut it properly."

"Yes, father, I did—the first time I shut it just as well as the second, and it didn't blow open after the second time. But I know I shut it well both times. I think it must be in the east, for it felt so sharp when it blew in."
