Context

“But he said it was nothing—nothing—and, laying her head upon his arm, patted her fair cheek with his hand, and muttered that she grew stronger every day, and would be a woman, soon.
CHAPTER 55 F rom that time, there sprung up in the old man’s mind, a solicitude about the child which never slept or left him. There are chords in the human heart—strange, varying strings—which are only struck by accident; which will remain mute and senseless to appeals the most passionate and earnest, and respond at last to the slightest casual touch. In the most insensible or childish minds, there is some train of reflection which art can seldom lead, or skill assist, but which will reveal itself, as great truths have done, by chance, and when the discoverer has the plainest end in view.” source
