"Philip."

"Philip what?"

"That will do to-day, thank you. The next time I call I will give you my full name and address."

"Please yourself. I am no judge in this matter," and he wrote on:

"Received from Philip, a boy who refuses any other name, but the same whom I saw in this office on the twentieth inst., and again at the Clerkenwell Police Court on that date, thirty meteoric diamonds weighing in the gross six hundred and twenty-nine carats. I hereby agree to dispose of the same, and to render true account of sales to the said Philip or his agents. My commission to be ten per cent.; the expenses payable by me. I have to-day handed the said Philip fifty pounds in gold, and undertake to place five thousand pounds to his credit to-morrow with my bankers.

"Reuben Isaacstein."

After completing this acknowledgment he scribbled something else.

"There," he said, with a sigh of relief, "that is not a very formal document, but it will suffice. You can get it stamped to-morrow at Somerset House. Just sign this receipt for fifty pounds."

Philip took the two papers and read them carefully. Isaacstein's handwriting was a scrawl, but legible enough. The boy reached for a pen and signed his Christian name. He was on the point of adding his surname in an unguarded moment, but he felt the Jew's eye on him. So he simply wrote "Philip" across the stamp at the foot of the receipt.

Isaacstein fully appreciated the incident, and knew that his own eagerness defeated the chance, all the more powerful because it was involuntary, of ascertaining the name of this marvelous youth.

Philip gathered up his gold, not without counting the coins. They felt strangely heavy in his pocket, much heavier than the stones they replaced. Yet they formed but a thousandth part of the value of those flintlike pebbles. What a queer problem it was, this ratio of worth between a few stones and the bright, minted sovereigns.
