ve that done, just try the experiment of sending us away
unsatisfied."

The old man bowed his white head.

"Your Highness," he said, "I shall take the responsibility of refusing to
obey the orders of the Director of Police. Excuse me for a moment."

He retired into his den, and presently emerged with a sheet of paper in
his hand.

"It must be understood," he said, addressing Jennie, "that the analysis
is but roughly made. I intended to devote the night to a more minute
scrutiny."

"All I want at the present moment," said Jennie, "is a rough analysis."

"There it is," said the chemist, handing her the paper. She read,----

Calcium 29
Iron 4
Quartz ]
Feldspar ] 27
Mica ]
Gold 36-1/2
Traces of other substances 3-1/2
-------
Total 100

Jennie's eyes sparkled as she looked at the figures before her. She
handed the paper to the Princess saying,--

"You see, I was right in my surmise. More than one-third of that heap is
pure gold."

"I should explain," said the chemist, "that I have grouped the quartz,
feldspar, and mica together, without giving the respective portions of
each, because it is evident that the combination represents granite."

"I understand," said Jennie; "the walls and the roof are of granite."

"I would further add," continued the chemist, "that I have never met
gold so finely divided as this is."

"Have you the gold and other ingredients separated?"

"Yes, madame."

"I shall take them with me, if you please."

The chemist shortly after brought her the components, in little glass
vials, labelled.

"Have you any idea, Herr Feltz, what explosive would reduce gold to such
fine powder as this?"

"I have only a theoretical knowledge of explosives, and I know of
nothing that would produce such results as we have here. Perhaps
Professor Carl Seigfried could give you some information on that point.
The science of detonation has been his life study, and he stands head
and shoulders above his fellows in that department."

"Can you give me his address?"

The chemist wrote the address on a sheet of paper and handed it to the
young woman.

"Do you happen to know whether Professor Seigfried or his assistants
have been called in during this investigation?"

"What investigation, madame?"

"The investigation of the recent terrible explosion."

"I have hear
