Mr. Jones was the constable, and Toby knew this quite as well as if he went on two feet instead of four. When Mr. Jones was sent to arrest any one, he always took Toby with him, and it was curious to see how the dog would watch the prisoner, and seem to feel that he had quite as much share as his master in bringing him to be punished for the wicked things he had done. As soon as Mr. Jones came in the room, he let go of Joe, but sat down close to him, ready to take another grip, if he tried to run away.
