"I beg your pardon, Fred," she hastened to say, holding out her hand, which he did not hesitate to take. "I was entirely wrong, and acted from a foolish impulse when I found that, in spite of all my precautions, more of my opals had mysteriously disappeared. You could not have taken them had you wanted to; and I do not believe you would touch them if you had a dozen chances."

That was saying a good deal for Miss Muster; and Fred, who knew considerable about her sharp tongue, felt that he could hardly have been paid a higher compliment.

"Thank you, ma'am," he said, smiling in a satisfied way. "If you please, then, we'll consider the thing closed. But that doesn't explain where the opals have gone to; does it?"

"Indeed, it does not," she replied. "I have been deeply stirred by this mystery; but Fred, believe me, it was not the value of the jewels one quarter so much as the shock given to my faith in human nature. I believed that the boy had been tempted beyond his power of resistance. Perhaps he wanted a certain sum of money for some purpose, and conceived the wicked idea that he could sell the stones, and get it that way. Oh! I would have gladly given him five, yes ten times their value, if only he had not given way to temptation."

"But Miss Muster," said Fred, quick to take advantage of his splendid opportunity; "you were just as sure, right now, that I was the thief; and yet how easy it was for me to prove my innocence. Wouldn't you be glad if I could do the same for my chum, Brist—I mean Andy?"

"Indeed, I would, Fred," she replied, warmly. "Do that, and there will be a whole shelf of boys' books come to your house, and an old woman's blessing in the bargain. But I'm afraid you'll find it a harder task than clearing your own skirts."

"But give me the chance, won't you, please, ma'am?" Fred insisted.

"Do you want to speak now about it, Fred?" she asked, eagerly enough.

"Why, yes, if you don't object, ma'am," he replied. "You know there's an old saying that 'it's best to strike while the iron is hot'."

"And you think that I'm pretty warm just now; is that it?" she asked, smiling a little in a way that made her thin face look almost friendly to the boy's imagination.
