Scarcely had he taken his seat, when again the door opened, this time admitting Mr. Graham, who was returning from Louisville, and had also found it convenient to call.  Involuntarily Durward glanced toward ’Lena, but her face was as calm and unruffled as if the visitor had been her uncle.

“All right there,” thought he, and withdrawing his eyes from her, he fixed them upon his father, who he fancied seemed somewhat disconcerted when he saw him there.  Mentally blaming himself for the distrust which he felt rising within him, he still determined to watch, and judge for himself how far his mother’s suspicions were correct.  Taking up a book which lay near, he pretended to be reading, while all the time his thoughts were elsewhere.  It was ’Lena’s lesson-day, and erelong Du Pont came in, appearing both pleased and surprised when he saw Mr. Graham.

“I hope you don’t expect me to expose my ignorance before all these people,” said ’Lena, as Du Pont motioned her to the stool.

“Suppose we adjourn to another room,” said Mabel, leading the way and followed by John Jr. only.

Durward at first thought of leaving also, and arose to do so, but on observing that his father showed no intention of going, he resumed his seat and book, poring over the latter as intently as if it had not been wrong side up!

“Does monsieur incline to stay,” asked Du Pont, as Mr. Graham took his station at the end of the piano.

“Certainly,” answered Mr. Graham, “unless Miss Rivers insists upon my leaving, which I am sure she would not do if she knew how much interest I take in her progress.”

So, during the entire lesson, Mr. Graham stood there, his eyes fixed upon ’Lena with a look which puzzled Durward, who from behind his book was watching him.  Admiration, affection, pity and remorse, all seemed mingled in the expression of his face, and as Durward watched, he felt that there was a something which he could not fathom.

“I never knew he was so fond of music,” thought he—­“I mean to put him to the test.”

Accordingly, when Du Pont was gone, he asked Mabel, who he knew was an excellent pianist, to favor him with one of her very best pieces—­“something lively and new which will wake us up,” said he.

Mabel would greatly have preferred remaining with John Jr., but she was habitually polite, always playing when invited, and now taking her seat at the piano, she brought out sounds far different from those of a new performer.  But Mr. Graham, if he heard it, did not heed it, his eyes and ears being alone for ’Lena.  Seating himself near her, he commenced talking to her in an undertone, apparently oblivious to everything else around him, and it was not until Durward twice asked how he liked Mabel’s playing, that he heard a note.  Then, starting up and going toward the instrument, he said, “Ah, yes, that was a fine march, (’twas the ‘Rainbow Schottish,’ then new,) please repeat it, or something just like it!”
