"Make your mind easy, your excellency! We shall find everything we require—blow-pipes and test-tubes and nitric acid, and even a decimal weighing machine. In our business we arrange matters in such a way that we need not disturb outsiders. Only charcoal we haven't got, but we can easily send for some."
And going to the door, he gave the servant in the passage an order, and a few minutes later the latter returned with a dish of charcoal.
"First class! Now everything is ready," cried Mr. Escrocevitch, rubbing his hands; and for greater security he turned the key in the door.
"Take whichever piece of charcoal you please, your excellency; but, not to soil your hands, you had better let me take it myself, and you sprinkle some of the dust on it," and he humbled himself before the prince. "Forgive me for asking you to do it all yourself, since it is not from any lack of politeness on my part, but simply in order that your excellency should be fully convinced that there is no deception." Saying this, he got his implements ready and lit the lamp.
The blow-pipe came into action. Valyajnikoff made the experiment, and Shadursky attentively followed every movement. The charcoal glowed white hot, the dust ran together and disappeared, and in its place, when the charcoal had cooled a little, and the amateur chemist presented it to Prince Shadursky, the prince saw a little ball of gold lying in a crevice of the charcoal, such as might easily have formed under the heat of the blow-pipe.
"Take the globule, your excellency, and place it, for greater security, in your pocketbook," said Escrocevitch; "you may even wrap it up in a bit of paper; and keep the sack of gold dust yourself, so that there can be no mistake."
Shadursky gladly followed this last piece of advice.
"And now, your excellency, I should like you kindly to select another bag; we shall make two or three more tests in the same way."
The prince consented to this also.
Escrocevitch handed him a new piece of charcoal to sprinkle dust on, and once more brought the blow-pipe into operation. And again the brass filings disappeared and in the crevice appeared a new globule of gold.
