Who said oh, it is a black mischief

This quote is not from Zora Neale Hurston. This quote is from Arthur Miller's 'The Crucible'. John Proctor says: "Oh, it is a black mischief" upon hearing Elizabeth's description of the Salem witch trials. It's an ironic statement because the "black mischief" to which Proctor refers is actually the blind hatred of the court--not the supposed witchcraft.
