Mrs. Northover stared to see the nature of a Spinner's duties and the ease with which she controlled the great, pulsing, roaring frame of a hundred spindles. Sabina's eyes were everywhere; her hands were never still; her feet seemed to dance a measure to the thunder of the Frame. Now she marked a roving reel aloft that was running out, and in a moment she had broken the sliver, swept away the empty reel and hung up a full one. Then she drew the new sliver down to the point of the break and, in a moment, the two merged and the thread ran on. Now her fingers touched the spindles, as a musician touches the keys, and at a moment's pressure the machine obeyed and the yarn flew on its way obedient. Now she cleared a snarl, or catch, where a spindle appeared to have run amuck or created hopeless confusion; now she readjusted the weights that kept a drag on the humming bobbins. Her twinkling hands touched and calmed and fed the monster. She knew its whims, corrected its errors, brought to her insensate machine the complement of brain that made it trustworthy. And when the bobbins were all full, she hastened along the Frame, turned off the driving power and silenced the huge activity in a moment. Then, like lightning, she cut her hundred threads and lifted the bobbins from their spindles until she had a pile upon her shoulder. In a marvellously short time she had doffed the bobbins and set up a hundred empty ones. Then the cut threads were readjusted, the power turned on and all was motion again. Sabina had never calculated her labours, until Raymond took the trouble to do so; then she learned a fact that astonished her. He found that it took a hundred and fifty minutes to spin one thousand and fifty yards; and as each spindle spun two and a half miles in ten hours, her daily accomplishment was two hundred and fifty miles of yarn. "You spin from seventy to eighty thousand miles of single yarn a year," he told her, and the fact expressed in these terms amazed her and her sister spinners. Now Nelly Northover praised the performance. "To think that you slips of girls can do anything so wonderful!" she said. "We talk of the spinners of Bridport as if they were nobodies; but upon my conscience, Sabina, I never will again. I've always thought I was a pretty busy woman; but I'd drop to the earth I'm sure after an hour of your job, let alone ten hours." Sabina laughed.
