Little Mavis hung back, but the boy bounded into the middle of the floor and started into a furious jig, his legs as loose from the hip as a jumping-jack and the soles and heels of his rough brogans thumping out every note of the music with astonishing precision and rapidity. He hardly noticed Mavis at first, and then he began to dance toward her, his eyes flashing and fixed on hers and his black locks tumbling about his forehead as though in an electric storm. The master was calling and the maid answered--shyly at first, coquettishly by and by, and then, forgetting self and onlookers, with a fiery abandon that transformed her. Alternately he advanced and she retreated, and when, with a scornful toss of that night-black head, the boy jigged away, she would relent and lure him back, only to send him on his way again. Sometimes they were back to back and the colonel saw that always then the girl was first to turn, but if the lad turned first, the girl whirled as though she were answering the dominant spirit of his eyes even through the back of her head, and, looking over to the bed, he saw his own little kinswoman answering that same masterful spirit in a way that seemed hardly less hypnotic. Even Gray's clear eyes, fixed at first on the little mountain girl, had turned to Jason, but they were undaunted and smiling, and when Jason, seeing Steve's face at the window and his mother edging out through the front door, seemed to hesitate in his dance, and Mavis, thinking he was about to stop, turned panting away from him, Gray sprang from the bed like a challenging young buck and lit facing the mountain boy and in the midst of a double-shuffle that the amazed colonel had never seen outdone by any darkey on his farm. "Jenny with a ruff-duff a-kickin' up the dust," clicked his feet. "Juba this and Juba that! Juba killed a yaller cat! Juba! Juba!" "Whoop!" yelled old Jason, bending his huge body and patting his leg and knee to the beat of one big cowhide boot and urging them on in a frenzy of delight: "Come on, Jason! Git atter him, stranger! Whoop her up thar with that fiddle--Heh--ee--dum dee--eede-eedle--dedee-dee!"
