"Thank you for showing it to me." With an effort of will she moved toward
the bridge, but was impelled by a consciousness of the abruptness of her
departure to look back at him once--and smile, to experience again the
thrill of the current he sped after her. By lifting his hat, a little
higher, a little more confidently than in the first instance, he made her
leaving seem more gracious, the act somehow conveying an acknowledgment

Once across the bridge and in the mill, she fairly ran up the stairs and
