Some dates fixed by this witness in Corwin's account, and entirely omitted in Cheever's, are interesting and somewhat important. We learn what, so far as we know, escaped the notice of all former searchers, that it was on Friday, January 15, just as she was going to sleep, that "one like a man" came to her and appointed a meeting there at Mr. Parris's house, to take place on the next Wednesday evening. Accordingly, on Wednesday evening, January 20, "the man" and four women came, and then designedly and deliberately pushed Tituba on, and made her pinch the daughter and niece of Mr. Parris; and _on that very evening_, Abigail, at least, if not Betty also, "_was first taken ill_." Here is an important and significant coincidence. Just at the time when the illness was developed, spirits, in compliance with a previous arrangement, were there present at work seeking to produce just such a result as was manifested. Did they, or did other agencies, produce the mysterious disorders which seemed to devil-dreading beholders like diabolical obsessions? In view of all the facts, it is plain that a spirit or spirits caused the children to suffer. By failing to present the above points, which, though lacking in the account that he copied and followed, yet came under his eye, Upham clearly failed to use some very important historic facts which are essential to a fair presentation of both the time at which, and the agents through whom, Salem witchcraft had its origin, and consequently to a fair presentation of its nature. But those facts strenuously conflict with his theory that embodied girls and women were the designers and perpetrators of that great and terrific manifestation of destructive forces. How strong the chains of a pet theory! How blinding the cataracts of long-cherished conclusions!
