In Act four of "The Crucible", what comments are made on the disruption of life in Salem other than the one about the cows?
By this time in the play, hundreds are in jail, which leaves farms and children untended, and questions in the minds of all of the townspeople as to whether or not the accusations of witchcraft were true or not.
At the beginning of Act Four, after the Tituba scene, Danforth, Hathorne and Cheever are discussing the disruptions in the town. Yes, wandering cows are certainly mentioned; with no one to milk them or tend them, they are wandering the town. As a result, people are fighting over "who they will belong to now." Hathorne wonders if Parris might be acting strangely, or if the events have made him go funny in the head. He remarks that Parris "has a mad look these days," and thinks it's because so many are in jail. Parris found a knife stabbed in his door, so is a bit worried for his life--the townspeople are turning on him and Abby.
One other big piece of news is that Abigail has stolen her uncle's money and fled town. This for sure seems to indicate that she was guilty of falsehood; the townspeople are starting to turn on her, so, she bails before it gets rough. This upsets Parris, because he is left penniless, and, it casts a bad reputation on his name. In addition to this, there has been "rebellion in Andover," a nearby town. In Andover, witch trials were going on also, but the townspeople overthrew the courts and declared them a fraud. This makes Danforth and Parris a bit nervous; they are worried Salem will go the same route.
So in addition to wandering livestock and parentless children, there is Abby skipping town, rebellion in other towns, and threats against Parris himself. I hope those thoughts help; good luck!
