But Belle would not answer, and all the rest of the afternoon she remained very silent and gloomy, looking, to tell the truth, as if that strange invisible little "black dog," that we have all heard of, I think, had seated himself comfortably upon her shoulders, with no intention of getting off again in a hurry.

It was a fine summer's day, almost too hot indeed, so the children had tea early and went out a walk afterwards, returning in time to spend half-an-hour with their mother, before she went to dress for dinner.

This half-hour was generally a very happy time for all the children. But to-day one little face was less bright than usual, and mamma's eyes were not slow to notice it, though she said nothing.

When the three little ones had gone off to bed, their mother glanced at the two elder girls.

"You are quite ready, I see, for coming into the drawing-room before dinner," she said.

"Yes, mamma," Lily replied, "all except washing our hands. They do get so quickly dirty in this hot weather, if we romp about at all."

"Then I think you might practise a little, papa likes to see one of you in the drawing-room when he comes in, and to-night Belle shall be with me while I'm dressing."

"Very well, mamma dear," said Lily, running off as cheerfully as usual. Being with their mother when she was dressing was a great treat, it didn't happen every night, and the little girls took it in turns. This evening I don't think Lily was at all sorry to be without her sister's company, for the little black dog, or at least his shadow, was still on Belle's shoulders.

Belle sat quietly in a corner of the room, her mother said very little to her, not even when Collins, the maid, had gone.
