" At milking-time Ma was putting on her bonnet, when suddenly all Jack’s hair stood up stiff on his neck and back, and he rushed out of the house. They heard a yell and a scramble and a shout: “Call off your dog! Call off your dog!”
Mr. Edwards was on top of the woodpile, and Jack was climbing up after him.
“He’s got me treed,” Mr. Edwards said, backing along the top of the woodpile. Ma could hardly make Jack come away. Jack grinned savagely and his eyes were red. He had to let Mr. Edwards come down from the woodpile, but he watched him every minute.
Ma said, “I declare, he seems to know that Mr. Ingalls isn’t here.”
Mr. Edwards said that dogs knew more than most folks gave them credit for. "
