Some of these stories proved to be too highly coloured even for the credulity of King James; and he rightly enough exclaimed that the witches were, like their master, 'extraordinary liars.' It is said, however, that he changed his opinion after Agnes Sampson, in a private conference which he accorded to her, related the details of a conversation between himself and the Queen that had taken place under such circumstances as to ensure inviolable secrecy. It is curious that a very similar story is told of Jeanne Darc--whom our ancestors burned as a witch--and King Charles VI. of France.
Despite the machinations of the devil and the witches, King James and Queen Anne, as we know, escaped every peril, and reached Leith in safety. The devil sourly remarked that James was 'a man of God,' and was evidently inclined to let him alone severely; but the Preston Pans conspirators, instigated, perhaps, by some powerful personages who kept prudently in the background, resolved on another attempt against their sovereign's life. On Lammas Eve (July 31, 1590), nine of the ringleaders, including Dr. Fian, Agnes Sampson, Euphemia Macalzean, and Barbara Napier, with some thirty confederates, assembled at the New Haven, between Musselburgh and Preston Pans, at a spot called the Fairy Holes, where they were met by the devil in the shape of a black man, which was 'thought most meet to do the turn for the which they were convened.' Agnes Sampson at once proposed that they should make a final effort for the King's destruction. The devil took an unfavourable view of the prospects of their schemes; but he promised them a waxen image, and directed them to hang up and roast a toad, and to lay its drippings--mixed with strong wash, an adder's skin, and 'the thing on the forehead of a new-foaled foal'--in James's path, or to suspend it in such a position that it might drip upon his body. This precious injunction was duly obeyed, and the toad hung up where the dripping would fall upon the King, 'during his Majesty's being at the Brig of Dee, the day before the common bell rang, for fear the Earl Bothwell should have entered Edinburgh.' But the devil's foreboding was fulfilled, and the conspirators missed their aim, the King happening to take a different route to that by which he had been expected.
