One familiar with the place would have noticed something, which, to his mind, would have seemed more surprising than the pageantry of the mountains in their morning sun-bath. Curling above one of the wild gorges that cut the lower slopes of the Tetons was a thick black smoke, which, when lifted by a passing breeze, obscured the precipices half-way to the summit of the peak.

Had the Grand Teton become a volcano? Certainly no hunting or exploring party could make a smoke like that. But a word from the leader of the party of horsemen explained the mystery.

“There is my mill, and the mine is underneath it.”

The speaker was Dr. Syx, and his companions were members of the financial congress. When he quitted their presence in New York, with the promise to return within an hour for their reply, he had no doubt in his own mind what that reply would be. He knew they would accept his proposition, and they did. No time was then lost in communicating with the various governments, and arrangements were quickly perfected whereby, in case the inspection of Dr. Syx’s mine and its resources proved satisfactory, America and Europe should unite in adopting the new metal as the basis of their coinage. As soon as this stage in the negotiations was reached, it only remained to send a committee of financiers and metallurgists, in company with Dr. Syx, to the Rocky Mountains. They started under the doctor’s guidance, completing the last stage of their journey on horseback.

“An inspection of the records at Washington,” Dr. Syx continued, addressing the horsemen, “will show that I have filed a claim covering ten acres of ground around the mouth of my mine. This was done as soon as I had discovered the metal. The filing of the claim and the subsequent proceedings which perfected my ownership attracted no attention, because everybody was thinking of the south pole and its gold-fields.”

The party gathered closer around Dr. Syx and listened to his words with silent attention, while their horses rubbed noses and jingled their gold-mounted trappings.

“As soon as I had legally protected myself,” he continued, “I employed a force of men, transported my machinery and material across the mountains, erected my furnaces, and opened the mine. I was safe from intrusion, and even from idle curiosity, for the reason I have just mentioned. In fact, so exclusive was the attraction of the new gold-fields that I had difficulty in obtaining workmen, and finally I sent to Africa and engaged negroes, whom I placed in charge of trustworthy foremen. Accordingly, with half a dozen exceptions, you will see only black men at the mine.”

“And with their aid you have mined enough metal to supply the mints of the world?” asked President Boon.

“Exactly so,” was the reply. “But I no longer employ the large force which I needed at first.”

“How much metal have you on hand? I am aware that you have already answered this question during our preliminary negotiations, but I ask it again for the benefit of some members of our party who were not present then.”
