For not more than the last ten years of his fifty he has really amounted to something." Ford leaned forward in the screen and spoke with sober emphasis: "And now, when he has reached his goal, what is his prize? His eyes are failing him, his bright young strength is gone, his heart and wind are‚ not what they used to be. He is not senile yet . . . but he feels the chill of the first frost. He knows what is in store for him. He knows-he knows! "
