Suddenly Uncle Henry stood up.
"There's a cyclone coming, Em," he called to his wife. "I'll go look after the stock."
Then he ran toward the sheds where the cows and horses were kept.
Aunt Em dropped her work and came to the door. One glance told her of the danger
close at hand.
"Quick, Dorothy!" she screamed. "Run for the cellar!"
Toto jumped out of Dorothy's arms and hid under the bed, and the girl started to get
him. Aunt Em, badly frightened, threw open the trap door in the floor and climbed
down the ladder into the small, dark hole. Dorothy caught Toto at last and started to
follow her aunt. When she was halfway across the room there came a great
shriek from the wind, and the house shook so hard that she lost her footing and sat
down suddenly upon the floor.
