Part 7 (1/2)

Beside the professor worked a young demonstrator of last year's graduation cla.s.s. It was he, in fact, who had written the polite notice on the card.

”What is the stuff, anyway?” he asked.

”A sulphuret of iron,” said the professor, ”or iron pyrites. In colour and appearance it is practically identical with gold. Indeed, in all ages,” he went on, dropping at once into the cla.s.sroom tone and adopting the professional habit of jumping backwards twenty centuries in order to explain anything properly, ”it has been readily mistaken for the precious metal. The ancients called it 'fool's gold.' Martin Frobisher brought back four s.h.i.+ploads of it from Baffin Land thinking that he had discovered an Eldorado. There are large deposits of it in the mines of Cornwall, and it is just possible,” here the professor measured his words as if speaking of something that he wouldn't promise, ”that the Ca.s.siterides of the Phoenicians contained deposits of the same sulphuret. Indeed, I defy anyone,” he continued, for he was piqued in his scientific pride, ”to distinguish it from gold without a laboratory-test. In large quant.i.ties, I concede, its lack of weight would betray it to a trained hand, but without testing its solubility in nitric acid, or the fact of its burning with a blue flame under the blow-pipe, it cannot be detected. In short, when crystallized in dodecahedrons-”

”Is it any good?” broke in the demonstrator.

”Good?” said the professor. ”Oh, you mean commercially? Not in the slightest. Much less valuable than, let us say, ordinary mud or clay. In fact, it is absolutely good for nothing.”

They were silent for a moment, watching the blue flames above the brazier.

Then Gildas spoke again. ”Oddly enough,” he said, ”the first set of samples were undoubtedly pure gold-not the faintest doubt of that. That is the really interesting part of the matter. These gentlemen concerned in the enterprise will, of course, lose their money, and I shall therefore decline to accept the very handsome fee which they had offered me for my services. But the main feature, the real point of interest in this matter remains. Here we have undoubtedly a sporadic deposit-what miners call a pocket-of pure gold in a Devonian formation of the post-tertiary period. This once established, we must revise our entire theory of the distribution of igneous and aqueous rocks. In fact, I am already getting notes together for a paper for the Pan-Geological under the heading, Auriferous Excretions in the Devonian Strata: a Working Hypothesis. I hope to read it at the next meeting.”

The young demonstrator looked at the professor with one eye half-closed.

”I don't think I would if I were you.” he said.

Now this young demonstrator knew nothing or practically nothing, of geology, because he came of one of the richest and best families in town and didn't need to. But he was a smart young man, dressed in the latest fas.h.i.+on with brown boots and a crosswise tie, and he knew more about money and business and the stock exchange in five minutes than Professor Gildas in his whole existence.

”Why not?” said the professor.

”Why, don't you see what's happened?”

”Eh?” said Gildas.

”What happened to those first samples? When that bunch got interested and planned to float the company? Don't you see? Somebody salted them on you.”

”Salted them on me?” repeated the professor, mystified.

”Yes, salted them. Somebody got wise to what they were and swopped them on you for the real thing, so as to get your certified report that the stuff was gold.”

”I begin to see,” muttered the professor. ”Somebody exchanged the samples, some person no doubt desirous of establis.h.i.+ng the theory that a sporadic outcropping of the sort might be found in a post-tertiary formation. I see, I see. No doubt he intended to prepare a paper on it, and prove his thesis by these tests. I see it all!”

The demonstrator looked at the professor with a sort of pity.

”You're on!” he said, and he laughed softly to himself.

”Well,” said Dr. Boomer, after Tomlinson had left the university, ”what do you make of him?” The president had taken Dr. Boyster over to his house beside the campus, and there in his study had given him a cigar as big as a rope and taken another himself. This was a sign that Dr. Boomer wanted Dr. Boyster's opinion in plain English, without any Latin about it.

”Remarkable man,” said the professor of Greek; ”wonderful penetration, and a man of very few words. Of course his game is clear enough?”

”Entirely so,” a.s.serted Dr. Boomer.

”It's clear enough that he means to give the money on two conditions.”

”Exactly,” said the president.

”First that we admit his son, who is quite unqualified, to the senior studies in electrical science, and second that we grant him the degree of Doctor of Letters. Those are his terms.” ”Can we meet them?”

”Oh, certainly. As to the son, there is no difficulty, of course; as to the degree, it's only a question of getting the faculty to vote it. I think we can manage it.”
