A certain degree of reaction, however, appeared to be taking place, and the magistrates who had conducted the proceedings began to be alarmed, and to have some doubts of the wisdom of their proceedings. Cotton Mather was called upon by the governor to employ his pen in justifying what had been done; and the result was, the book which stands first in the present volume, "The Wonders of the Invisible World;" in which the author gives an account of seven of the trials at Salem, compares the doings of the witches in New England with those in other parts of the world, and adds an elaborate dissertation on witchcraft in general. This book was published at Boston, Massachusetts, in the month of October, 1692. Other circumstances, however, contributed to throw discredit on the proceedings of the court, though the witch mania was at the same time spreading throughout the whole colony. In this same month of October, the wife of Mr. Hale, minister of Beverley, was accused, although no person of sense and respectability had the slightest doubt of her innocence; and her husband had been a zealous promoter of the prosecutions. This accusation brought a new light on the mind of Mr. Hale, who became convinced of the injustice in which he had been made an accomplice; but the other ministers who took the lead in the proceedings were less willing to believe in their own error; and equally convinced of the innocence of Mrs. Hale, they raised a question of conscience, whether the devil could not assume the shape of an innocent and pious person, as well as of a wicked person, for the purpose of afflicting his victims. The assistance of Increase Mather, the president or principal of Harvard College, was now called in, and he published the book which is also reprinted in the present volume: "A Further Account of the Tryals of the New England Witches.... To which is added Cases of Conscience concerning Witchcrafts and Evil Spirits personating Men." It will be seen that the greater part of the "Cases of Conscience" is given to the discussion of the question just alluded to, which Increase Mather unhesitatingly decides in the affirmative. The scene of agitation was now removed from Salem to Andover, where a great number of persons were accused of witchcraft and thrown into prison, until a justice of the peace named Bradstreet, to whom the accusers applied for warrants, refused to grant any more. Hereupon they cried out upon Bradstreet, and declared that he had killed nine persons by means of witchcraft; and he was so much alarmed that he fled from the place. The accusers aimed at people in higher positions in society, until at last they had the audacity to cry out upon the lady of governor Phipps himself, and thus lost whatever countenance he had given to their proceedings out of respect to the two Mathers. Other people of character, when they were attacked by the accusers, took energetic measures in self-defence. A
