“Give an Indian a modern rifle in place of his bow and arrows and he will become a vastly more efficient game-getter. The Indian hunter himself has not changed in the slightest. But his entire Indian race sported so few of the above-average men, that all of them, in ten thousand generations, were unable to equip him with a rifle.”

“Go on, Dick, develop the idea,” Terrence encouraged. “I begin to glimpse your drive, and you’ll soon have Aaron on the run with his race prejudices and silly vanities of superiority.”

“These above-average men,” Dick continued, “these pace-makers, are the inventors, the discoverers, the constructionists, the sporting dominants. A race that sports few such dominants is classified as a lower race, as an inferior race. It still hunts with bows and arrows. It is not equipped. Now the average white man, per se, is just as bestial, just as stupid, just as inelastic, just as stagnative, just as retrogressive, as the average savage. But the average white man has a faster pace. The large number of sporting dominants in his society give him the equipment, the organization, and impose the law.

“What great man, what hero—­and by that I mean what sporting dominant—­ has the Hottentot race produced? The Hawaiian race produced only one—­ Kamehameha. The negro race in America, at the outside only two, Booker T. Washington and Du Bois—­and both with white blood in them....”

Paula feigned a cheerful interest while the exposition went on. She did not appear bored, but to Graham’s sympathetic eyes she seemed inwardly to droop. And in an interval of tilt between Terrence and Hancock, she said in a low voice to Graham:

“Words, words, words, so much and so many of them! I suppose Dick is right—­he so nearly always is; but I confess to my old weakness of inability to apply all these floods of words to life—­to my life, I mean, to my living, to what I should do, to what I must do.” Her eyes were unfalteringly fixed on his while she spoke, leaving no doubt in his mind to what she referred. “I don’t know what bearing sporting dominants and race-paces have on my life. They show me no right or wrong or way for my particular feet. And now that they’ve started they are liable to talk the rest of the evening....

“Oh, I do understand what they say,” she hastily assured him; “but it doesn’t mean anything to me. Words, words, words—­and I want to know what to do, what to do with myself, what to do with you, what to do with Dick.”

But the devil of speech was in Dick Forrest’s tongue, and before Graham could murmur a reply to Paula, Dick was challenging him for data on the subject from the South American tribes among which he had traveled. To look at Dick’s face it would have been unguessed that he was aught but a carefree, happy arguer. Nor did Graham, nor did Paula, Dick’s dozen years’ wife, dream that his casual careless glances were missing no movement of a hand, no change of position on a chair, no shade of expression on their faces.

What’s up? was Dick’s secret interrogation. Paula’s not herself. She’s positively nervous, and all the discussion is responsible. And Graham’s off color. His brain isn’t working up to mark. He’s thinking about something else, rather than about what he is saying. What is that something else?

And the devil of speech behind which Dick hid his secret thoughts impelled him to urge the talk wider and wilder.
