What does Lord Blakeney do when he is challenged to a duel in the Fisheman's Rest?

From the text:

He laughed his own pleasant and inane laugh, and burying his slender, long hands into the capacious pockets of his overcoat, he said leisurely—“a bloodthirsty young ruffian, Do you want to make a hole in a law-abiding man? . . . As for me, sir, I never fight duels,” he added, as he placidly sat down and stretched his long, lazy legs out before him.
