"Good night!" said Susan D. Margaret shut the door softly and went away. As she passed along the corridor that ran round the hall, something struck her forehead lightly. She looked up, and narrowly escaped getting a fish-hook in her eye. Merton looked over the banisters, and smiled appealingly. "I was fishin'," he said. "There's fish-lines in the drawers of the sofa. I guess I 'most caught a whale, didn't I?"

"Merton, you must go to bed at once!" said Margaret. "How long have you been standing there in your nightgown? You might catch your death." (It had been one of old Katy's maxims that if you stood about in your nightgown for however short a time, you inevitably got your death. Margaret had never doubted it till this moment.) "I am coming up now to tuck you both up!" she added, with a happy inspiration.

There was a hasty scuffle, then a rush, accompanied by smothered squeals. When Margaret reached the nursery, both boys were in bed. Merton's blue eyes were wide open, and fixed on her with mournful earnestness; Basil was asleep, the clothes tucked in well under his chin. He lay on his back, his mouth slightly opened; he was snoring gently, but unobtrusively. Poor child! no doubt he was tired enough. But how had Merton managed to make so much noise?

Margaret looked around her, and Merton's gaze grew more intense. His own clothes lay in a heap on the floor, but where were his brother's? And—and what was that, smoothly folded over the back of a chair? A clean nightgown?

But when Merton saw his cousin's eyes fix on the nightgown, he exploded in a bubbling laugh. "He—he ain't undressed at all!" he cried, gleefully. "He never! he's got his boots on, and every single—" The speech got no further. There was a flying whirl of blankets, a leap, and Basil was on his brother's chest, pounding him with right good will. "You sneak!" he cried. "I'll teach you—"

There was no time to think; the child would be killed before her eyes. Margaret took a firm hold on Basil's collar, and dragged him off by main strength, he still clawing the air. Unconsciously, she gave him a hearty shake before she let go; the boy staggered back a few paces; who would have thought that Margaret had such strength in her slender wrists? The crisis over, she panted, and felt faint for an instant; Basil, after a moment of bewilderment, looked at her, and the smile broke all over his face, a moment before black with rage.

"Got me that time, didn't you?" he said, simply. "He's a mean sneak, Mert is. I'll serve him out to-morrow, don't you be afraid!"

"Basil, what does this mean?" asked Margaret, severely. "Why are you not in bed?" Then as Basil sent an eloquent glance at the pillow where his head had been lying so quietly, she added, "Why are you not undressed, I mean? I am afraid you have been very naughty, both of you, boys."

"Well, you see," said Basil, apologetically, "there was all kinds of things in the drawers, and then I got on the rocking-horse, and it wasn't but just a minute before you came up. I say, isn't this a bully room, Cousin Margaret? I think Uncle John was awfully good to give us such a room as this. Why doesn't he sleep here himself? Bet I would, if I owned the house. I say, do those marbles belong to him?"

"I suppose so," said Margaret, smiling in spite of herself; "yes, I am sure they were his. But now, Basil,—"
