"I have the word both of her mother and father."

"Well, I won't take their word. Some natures are their own defense. On them no stain can rest, and I stake my life on Helen's!"

"My boy——"

"Oh, I know what you're going to say—as a theory it's quite correct. But it's one thing to accept a theory, another to meet the thing in your own heart before God alone with your life in your hands."

"What do you mean by that?" the father asked savagely.

"That for the past hour I've been doing some thinking on my own account."

"That's just what you haven't been doing. You haven't thought at all. If you had, you'd know that you can't marry this girl. Come, come, my boy, remember that you have reason and because you have this power that's bigger than all passion, all desire, all impulse, you're a man, not a brute——"

"All right," the boy broke in excitedly, "submit it to reason! I'll stand the test—it's more than you can do. I love this girl—she's my mate. She loves me and I am hers. Haven't I taken my stand squarely on Nature and her highest law?"
