"A musical genius came to the Suspension Bridge at Niagara Falls, and asked permission to cross; but as he had no money, his request was contemptuously refused. He stepped away from the entrance, and, drawing his violin from his case, began sounding notes up and down the scale. He finally discovered, by the thrill that sent a tremor through the mighty structure, that he had found the note on which the great cable that upheld the mass, was keyed. He drew his bow across the string of the violin again, and the colossal wire, as if under the spell of a magician, responded with a throb that sent a wave through its enormous length. He sounded the note again and again, and the cable that was dormant under the strain of loaded teams and monster engines - the cable that remained stolid under the pressure of human traffic, and the heavy tread of commerce, thrilled and surged and shook itself, as mad waves of vibration coursed over its length, and it tore at its slack, until like a foam-crested wave of the sea, it shook the towers at either end, or, like some sentient animal, it tugged at its fetters and longed to be free."The officers in charge, apprehensive of danger, hurried the poor musician across, and bade him begone and trouble them no more. The ragged genius, putting his well-worn instrument back in its case, muttered to himself, 'I'd either crossed free or torn down the bridge.'""So the hypnotist," goes on the writer from which the above is quoted, "finds the note on which the subjective side of the person is attuned, and by playing upon it awakens into activity emotions and sensibilities that otherwise would have remained dormant, unused and even unsuspected."
