Mr. Clark put out his hand.
"I am glad you told me this, Thornton," he said quietly, "and I believe you. See, here is a sheet of paper, it is scrawled over with letters and
figures of every sort. Turn it over."

"You see there is nothing on that side," went on Donald's father. "We can there write what we will. Turn your own page the same way. Let us
forget the past. Now for the future! Will you take the position as manager of Crescent Ranch?"
