Read it through once

Now, the old sofa was a regular patriarch of a sofa,--long, broad, well-cushioned, and low; a trifle shabby, as well it might be, for the girls had slept and sprawled on it as babies, fished over the back, rode on the arms, and had menageries under it as children, and rested tired heads, dreamed dreams, and listened to tender talk on it as young women. They all loved it, for it was a family refuge, and one corner had always been Jo's favorite lounging-place. Among the many pillows that adorned the venerable couch was one, hard, round, covered with prickly horsehair, and furnished with a knobby button at each end; this repulsive pillow was her especial property, being used as a weapon of defence, a barricade, or a stern preventive of too much slumber.
