"Lucy," she said, "have you met Mr. Weston before to-day?"

"No, Margaret," was Lucy's answer. "What makes you ask?"

"Something in your face--that's all."

There was something in Lucy's face while these few words were being uttered--a blush, which quickly died out, leaving her paler than before. Margaret instantly began putting two and two together. An easy task, some of you may think. You are much mistaken. It is a task which requires, and often defies, abstruse calculation, and where a man will succeed in it once, a woman will succeed a hundred times. There are three great discoveries yet to be made in the world--perpetual motion, how to square the circle, and how many beans make five. Depend upon it, if they ever are discovered, they will be placed to the credit of women.

Less difficult, certainly, than any of these, was the task upon which Margaret was at present engaged. But shrewd as she was, she was far from seeing her way clearly. The sum was not completely set before her. There was a figure wanting.

"I don't quite know, Lucy," she said, "whether I like Mr. Weston."

Lucy looked at Margaret reproachfully. Not like her father's old friend! Why, what could Margaret be thinking about? But Margaret, had she pleased, could have justified herself. She had, or fancied she had, observed an expression of uneasiness and dissatisfaction on Mr. Weston's face when his eyes rested on his friend's clothes. They were decent, but not new; and if they had been new, they would not have been fine. This uneasy glance lasted only for an instant, but it had made an impression on Margaret's mind not easily to be effaced. "Trifles light as air are to the jealous confirmation strong as proofs of holy writ;" and Margaret was a woman who judged by trifles. It is strange that this should be rare when the waving of a straw proclaims how the wind blows.

It was a lovely summer's day, and the beautiful grounds which surrounded Mr. Weston's house were bright with colour. Every material comfort that could make life enjoyable was to be found within this pretty estate. The house was luxuriantly furnished; the gardens were carefully tended; and evidences of good taste met the eye on every side. Noticing these substantial signs of comfort and refinement, Margaret noticed, also, that Mr. Weston was directing the attention of his friend to the beauty of the place. To her eyes there was ostentation in his manner. "He is proud of his wealth," she said, and fell again to the study of her sum of two and two. While thus employed, her eyes wandered to Lucy's face. It was very sad and pitiful. Margaret had played the part of Maria in "Twelfth Night," and Viola's word came to her mind:

She never told her love,
But let concealment, like a worm i' the bud,
Feed on her damask cheek; she pined in thought.

As Lucy was pining now. Margaret, from her woman's instinct, knew full well that a secret sorrow born of love was preying on the heart of this tender girl, and she was striving to find a way into her friend's confidence, when, at that very moment, chance befriended her, and the clue for which she was seeking was put into her hands. A sudden flame in Lucy's face, a sudden glad light in her eyes, a sudden exclamation of pleasure in which her misery seemed to die, a sudden uprising of the girl's form towards the framework of the balcony, and the secret was revealed, and the sum was done.
