He approached and bent above the bed. The face turned upward there seemed like wax in the oft-broken gloom. The sleeper had not stirred. It was the vibration of chords in harmony, that had moved him. Would it have power again? He hesitated a moment, then returned quickly to the wing-room and secured his instrument. Concealing himself he waited. It was but a moment.

The wind brought the branches of the nearest oleanders against the frail walls, and the play of lightning had become continuous. Then began in earnest the tumult of the vast sound waves as they met in the vapory caverns of the sky. The sleeper tossed restlessly upon his bed; he was stirred by a vague but unknown power; yet something was wanting.

At this moment Edward lifted his violin and, catching the storm note, wove a solemn strain into the diapason of the mighty organ of the sky. And as he played, as if by one motion, the sleeper stood alone in the middle of the room. Again Edward saw that frenzied stare fixed upon vacancy, but there was no furious leap of the agile limbs; by a powerful effort the struggling mind seemed to throw off a weight and the sleeper awoke.

The bow was now suspended; the music had ceased. Gerald rushed to his easel and, standing in a sea of electric flame, outlined with swift strokes a woman's face and form. She was struggling in the grasp of a man and her face was the face of the artist who worked. But such expression! Agony, horror, despair!

The figure of the man was not complete from the waist down; his face was concealed. Between them, as they contended, was a child's coffin in the arms of the woman. Overhead were the bare outlines of an arch.

The artist hesitated and added behind the group a tree, whose branches seemed to lash the ground. And there memory failed; the crayon fell from his fingers; he stood listless by the canvas. Then with a cry he buried his face in his hands and wept.

As he stood thus, the visitor, awed but triumphant, glided through the door and disappeared in the wing-room. He knew that he had touched a hidden chord; that the picture on the canvas was born under the flashlight of memory! Was it brain? Oh, for the wisdom of Virdow!

Sympathy moved him to return again to the glass-room. It was empty!
