But for my part, I felt there was a show of reason in one last taunt which the rascal flung back at us as the boat receded: "Sir Charles Vandrift, we are a pair of rogues. The law protects _you_. It persecutes _me_. That's all the difference." VI THE EPISODE OF THE GERMAN PROFESSOR That winter in town my respected brother-in-law had little time on his hands to bother himself about trifles like Colonel Clay. A thunderclap burst upon him. He saw his chief interest in South Africa threatened by a serious, an unexpected, and a crushing danger. Charles does a little in gold, and a little in land; but his principal operations have always lain in the direction of diamonds. Only once in my life, indeed, have I seen him pay the slightest attention to poetry, and that was when I happened one day to recite the lines:-- Full many a gem of purest ray serene The dark, unfathomed caves of ocean bear. He rubbed his hands at once and murmured enthusiastically, "I never thought of that. We might get up an Atlantic Exploration Syndicate, Limited." So attached is he to diamonds. You may gather, therefore, what a shock it was to that gigantic brain to learn that science was rapidly reaching a point where his favourite gems might become all at once a mere drug in the market. Depreciation is the one bugbear that perpetually torments Sir Charles's soul; that winter he stood within measurable distance of so appalling a calamity. It happened after this manner. We were strolling along Piccadilly towards Charles's club one afternoon--he is a prominent member of the Croesus, in Pall Mall--when, near Burlington House, whom should we happen to knock up against but Sir Adolphus Cordery, the famous mineralogist, and leading spirit of the Royal Society! He nodded to us pleasantly. "Halloa, Vandrift," he cried, in his peculiarly loud and piercing voice; "you're the very man I wanted to meet to-day. Good morning, Wentworth. Well, how about diamonds now, Sir Gorgius? You'll have to sing small. It's all up with you Midases. Heard about this marvellous new discovery of Schleiermacher's? It's calculated to make you diamond kings squirm like an eel in a frying-pan." I could see Charles wriggle inside his clothes. He was most uncomfortable. That a man like Cordery should say such things, in so loud a voice, on no matter how little foundation, openly in Piccadilly, was enough in itself to make a sensitive barometer such as Cloetedorp Golcondas go down a point or two. "Hush, hush!" Charles said solemnly, in that awed tone of voice which he always assumes when Money is blasphemed against. "_Please_ don't talk quite so loud! All London can hear you." Sir Adolphus ran his arm through Charles's most amicably. There's nothing Charles hates like having his arm taken.
