Question

“Giles: That bloody mongrel Walcott charge her. Y’see, he buy a pig of my wife four of five year ago, and the pig died soon after. So he come dancin’ in for his money back. So my Martha, she says to him, “Walcott, if you haven’t the wit to feed a pig properly, you’ll not live to own many,” she says. Now he goes to court and claims that from that day to this he cannot keep a pig for more than four weeks because my Martha bewitch them with her books!” (Miller, Act 2, 72).

Answer 1

Giles bought a pig from Walcott and the pig died. He wanted his money back but was told that it was his fault that the pig died. Over the next few years Giles bought several pigs which all died. He believed that Walcott put a curse on him and was responsible for all his pigs dieing.

Giles wanted a scape goat for his poor husbandry skills. To call Martha a "witch" absolved him of all blame and he could probably get a part of her estate to compensate him for his losses.

Answer 2

I'm sorry, but I don't understand your question. the quote is an interesting bit of Miller's dialogue - and is self explanatory, but your question baffles me.
