Here's a short story:

CHAPTER XV--A DISCOURSE ON MANNERS 

The days passed, and Tudor seemed loath to leave the hospitality of Berande. Everything was ready for the start, but he lingered on, spending much time in Joan's company and thereby increasing the dislike Sheldon had taken to him. He went swimming with her, in point of rashness exceeding her; and dynamited fish with her, diving among the hungry ground-sharks and contesting with them for possession of the stunned prey, until he earned the approval of the whole Tahitian crew. Arahu challenged him to tear a fish from a shark's jaws, leaving half to the shark and bringing the other half himself to the surface; and Tudor performed the feat, a flip from the sandpaper hide of the astonished shark scraping several inches of skin from his shoulder. And Joan was delighted, while Sheldon, looking on, realized that here was the hero of her adventure-dreams coming true. She did not care for love, but he felt that if ever she did love it would be that sort of a man--"a man who exhibited," was his way of putting it. 

He felt himself handicapped in the presence of Tudor, who had the gift of making a show of all his qualities. Sheldon knew himself for a brave man, wherefore he made no advertisement of the fact. He knew that just as readily as the other would he dive among ground-sharks to save a life, but in that fact he could find no sanction for the foolhardy act of diving among sharks for the half of a fish. The difference between them was that he kept the curtain of his shop window down. Life pulsed steadily and deep in him, and it was not his nature needlessly to agitate the surface so that the world could see the splash he was making. And the effect of the other's amazing exhibitions was to make him retreat more deeply within himself and wrap himself more thickly than ever in the nerveless, stoical calm of his race.
