The only reply of the Lad was a motion of the bow; but the motion was effective, for it sent a torrent of notes into the air, which thrilled through the body and tingled along the nerves like successive electric shocks. The old Trapper fairly bounded into the air; and when he struck the floor his feet were flying. Nor was he alone; the jig had started a dozen on the instant; and the floor rattled and rang with the tap of toe and heel. "Henry," said the old Trapper, "hold on to me or I shall sartinly make a fool of myself. The Lad is ticklin' me from head to foot, and my toes are snappin' inside of the moccasins. Lord, who'd a thought that the blood in the veins of a man whose head is whitenin' could be sot leapin' as mine is doin' at this minit by the scrapin' of a fiddle!" The Lad was a picture to see. His bow flew like lightning. His long fingers drummed and slid along the strings of the violin with bewildering swiftness. The little instrument jetted and effervesced its melody. The continuous and resounding noise poured out of it in tuneful bubbles. The air was filled with tinkling fragments of sound. The Lad's body swayed to and fro. His face glowed. His eyes flashed. The sweat stood in drops on his forehead, but still the bow snapped and crinkled, and the instrument continued to burst in musical explosions, while the floor shook, the windows rattled, and the lamps flared and fluttered, as the dancers chased the music on. [Illustration: "_The music stopped with a snap._"] "Heavens and arth!" said the Trapper. "I can't stand this," and breaking from the hold that Herbert had on him, whirled himself out to the centre of the floor and, with his face aflame with excitement and his white hair flying abroad, led the jig men off with a lightness of foot and quickness of stroke that forced the music by half a beat. The effect was electric. The room burst into applause, and the Lad fetched a stroke that seemed to rip the violin asunder. It was now a race between the violin and the dancers. One after another fell out of the circle as the moments passed, until the Trapper was left alone and was cutting it down in a fashion that both astonished and convulsed the company. More than one of the spectators went on to the floor in paroxysms of laughter. Herbert, bent over with his hands on his knees, was watching the Trapper with mouth stretched to its utmost and streaming eyes. It is impossible to say which would have triumphed, had not an accident decided the contest and brought the jig to an abrupt termination. For even while the Lad was in the midst of the swiftest execution, the hind legs of the chair in which he was sitting were whipped from their fastenings, his heels went into the air, he turned half a somersault backward and the music stopped with a snap.
