It's Saturday.
One day they were helping Ma get dinner. Baby Carrie was playing on the floor in the sunshine, and suddenly the sunshine was gone. Ma said that she didn't believe it was going to storm, looking out of the window. Laura looked, too, and great black clouds were billowing up in the south, across the sun. Pet and Patty were coming running from the field, Pa holding to the heavy plow and bounding in long leaps behind it. He shouted prairie fire and asked them to get the tub full of water and put sacks in it. Ma ran to the well, Laura ran to tug the tub to it. Pa tied Pet to the house. He brought the cow and calf from the picket-line and shut them in the stable. He caught Bunny and tied her fast to the north corner of the house. Ma was pulling up buckets of water as fast as she could. Laura ran to get the sacks that Pa had flung out of the stable. Pa was plowing, shouting at Pet and Patty to make them hurry. The sky was black now, the air was as dark as if the sun had set. Pa plowed a long furrow west of the house and south of the house,? and back again east of the house. Rabbits came bounding past him as if he wasn't there. Pet and Patty came galloping, the plow and Pa bounding behind them. Pa tied them to the other north corner of the house. The tub was full of water. Laura helped Ma push the sacks under the water to soak them. Pa said that he couldn't plow but one furrow; there wasn't time. And he asked Ma to hurry, and told her that that fire was coming faster than a horse could run. A big rabbit bounded right over the tub while Pa and Ma were lifting it. Ma told Laura to stay at the house. Pa and Ma ran staggering to the furrow with the tub.?
