But the Senior Partner still marveled that any educated person should prove so gullible as to be deceived by this object in his hand. He looked again, and more carefully, at the visitor's face. This time the boyish mouth seemed to indicate nothing but inexperience. The heavy lidded eyes, however, calmly returned the searching gaze, as if they themselves were searching;—yet in a sleepy way, it seemed to the Senior Partner. And the Senior Partner was strengthened in his conviction that a man with those eyes and with such a mouth could believe almost anything. Yet he liked the young man's face. His voice was pleasant, and his manner of speech, while punctiliously polite and considerate of others, indicated decision and self-reliance.

"But, Uncle Fred," said William, "it is so heavy for its size. And it's cold, like a diamond. And it has that oily feeling on the polished face. It surely is not an artificial stone."

"No, possibly not. But the color, this pale, apple green, while an exquisite tint, is not usual in diamonds."

"But the famous 'Dresden' is that color, isn't it?"

"Yes, I believe so; but the famous 'Dresden' is smaller than a paving stone. This object, as you see, if a natural stone, must have been nearly twice its present dimensions before cutting. And even now it is fully twice the size of any diamond of which we have ever heard. You young gentlemen will admit that it must be the house of an exceedingly prosperous person where bulky door knobs were composed of single diamonds."

Nephew William frowned and drummed with his fingers on the top of the desk.

"And I doubt," continued the Senior Partner with his pleasant smile, "if there are many mines that yield jewels the size of ostrich eggs."

Cyrus Alton's eyes, in a dreamy way, were fixed upon the stone. "Couldn't this have come from some other planet?"

"Possibly, as a meteorite. But precious stones have not the habit of coming from that direction. However, nothing concerning astronomy can surprise us. Might I ask where you found it, Mr. Alton?"

Mr. Alton hesitated. As he drew a hand across his forehead the Senior Partner and his nephew noticed a hole in the faded and shiny coat sleeve; also that the linen cuff with its frayed edges had no fastenings. William's silent guess was correct. "The poor chap has had to sell his cuff buttons."
