"I suppose you'd like some tallow-drops, sir?" he said. "Tallow-drops work-in better than anything for a necklace."

"What, in Heaven's name, are tallow-drops?"

Mr. Hartgold took up a diamond with a pair of pincers, and exhibited it to the banker.

"That's a tallow-drop, sir," he said. "It's something of a heart-shaped stone, you see; but we call it a tallow-drop, because it's very much the shape of a drop of tallow. You'd like large stones, of course, though they eat into a great deal of money? There are diamonds that are known all over Europe; diamonds that have been in the possession of royalty, and are as well known as the family they've belonged to. The Duke of Brunswick has pretty well cleared the market of that sort of stuff; but still they are to be had, if you've a fancy for anything of that kind?"

Mr. Dunbar shook his head.

"I don't want anything of that sort," he said; "the day may come when my daughter, or my daughter's descendants, may be obliged to realize the jewels. I'm a commercial man, and I want eighty thousand pounds' worth of diamonds that shall be worth the money I give for them to break up and sell again. I should wish you to choose diamonds of moderate size, but not small; worth, on an average, forty or fifty pounds apiece, we'll say."

"I shall have to be very particular about matching them in colour," said Mr. Hartgold, "as they're for a necklace." The banker shrugged his shoulders.

"Don't trouble yourself about the necklace," he said, rather impatiently. "I tell you again I'm a commercial man, and what I want is good value for my money."

"And you shall have it, sir," answered the diamond-merchant, briskly.

"Very well, then; in that case I think we understand each other, and there's no occasion for me to stop here any longer. You'll have eighty thousand pounds' worth of diamonds, at thereabouts, ready for me when I call here on Thursday morning. You can cash that cheque in the meantime, and ascertain with whom you have to deal. Good morning."
