Every town and county had its witch-finder, whose duty it was to detect and bring to trial all those tainted with witchcraft or sorcery. Considering that almost every accident which happened was attributed to sorcery, the duties of the witch-finder were most important. According to his diligence so was the safety of persons and property. Hail-storms, destructive floods, dangerous fires, disease among cattle, and domestic afflictions were all ascribed to witchcraft. A mole or wart discovered on any part of an old woman's body was thought to be a witch-mark. If a suspected witch did not shed tears, it was presumptive evidence of guilt; if she kept a black cat, it was taken for a familiar; and all these circumstances together were regarded as infallible signs of her evil nature. An expert witch-finder knew all the wiles and arts of his profession. To prepare the suspected witch for judicial examination, a particular diet was sometimes given her, to counteract the unguents she had anointed herself with, to make non-effective the preparations of belladonna, aconite, parsley, and other ingredients she had swallowed, and to render of no effect the charmed cocks' combs and rams' kidneys partaken of by her.

John Kinnaird, a witch-finder, some hundreds of years past, brought many witches to justice in his time. In 1649 he pricked Patrick Watson, of West Fenton, and Minie Haliburton his wife, and found the devil's mark on the husband's back, and the same evil one's impress on the wife's neck. Though the operator thrust his sharp instrument deep into the spots, no pain was felt, nor did blood flow. These results proved that the accused husband and wife were in league with Satan; and Minie, seeing it was useless to deny her guilt, admitted the crime.

Under judicial examination, witches have confessed to having met the devil at his Sabbaths, the meetings always taking place near a cross road, upon a dreary moor, or beside a lake or stagnant pool, on Wednesday and Friday nights. At the meetings children were presented, so they said, to Satan. At these gatherings sorcerers were supplied with exquisite meat and drink, served in vessels of gold and silver; and at other times with cooked toads, unbaptised children, and the flesh of malefactors cut down from gibbets. Toads, having the rank of witches' familiars, appeared at the meetings, dressed in gay attire, and wearing small silver bells round their necks, or attached to their feet. At cock-crow Satan disappeared under the earth, and the witches flew through the air to their respective homes. That witches could transform themselves into hares, wolves, and other animals, nearly all the accused women readily admitted.

In the year 1728 a witch-finder discovered that a stout tall woman, suspected of sorcery, did not weigh more than four ounces. This was enough to make out a case against her; and not only against her, but against several confederates, and they were all burned in terms of law.

On account of a petition presented by the inhabitants of Newcastle to the authorities, in the year 1649, concerning the evil consequences of witchcraft, the magistrates sent two of their officers to Scotland to secure the services of a celebrated witch-finder, famous for detecting witches by means of pricking them with sharp instruments. The cunning man agreed to go with them to Newcastle to try such suspected persons as might be brought to him, at the rate of twenty shillings for every woman found guilty. When the officers brought the witch-finder to town, the magistrates sent their bellman through the streets to invite the inhabitants who had complaints to make against witches to make them without delay, that they (the witches) might be tried by the person appointed. Thirty women were brought to the town hall, and had pins thrust into their flesh, and most of them were found guilty. The witch-finder informed Lieutenant-Colonel Hobson that he knew whether women were witches or no by their looks. On a good-looking woman being brought to the finder, the gallant colonel thought it was unnecessary to try her, but the canny Scotchman knew better, and therefore submitted her to his infallible test. Having put a pin into her side, he marked her down a witch of the devil. The colonel, not satisfied that the woman was guilty, remonstrated, and then the witch-finder confessed he was in error. The highly-favoured damsel was therefore liberated; but as no champion appeared for the poor old withered hags, they suffered the pains of law.

Having rid Newcastle of witches, the witch-finder was summoned to Northumberland county to try women there for sixty shillings each. For some fault or crime connected with the discharge of his official duties, he was apprehended, and put under bond to appear at the sessions to answer such charges as might be brought against him. He escaped to Scotland, where he was made prisoner, indicted, and condemned for villany, exercised on the north side of the Tweed, in connection with witch-finding. He confessed that he had been instrumental in bringing to an untimely end above two hundred and twenty women in England and Scotland.

Matthew Hopkins, who regularly went on circuit in England to detect witches for a long period subsequent to the year 1644, applied the usual tests, such as finding witch-marks, thrusting sharp instruments into the bodies of suspected persons, dragging them through deep water while they were wrapped in sheets, with their great toes and thumbs tied together, keeping his victims awake sometimes as long as forty-eight hours to make them confess, ascertaining whether they could repeat the Lord's Prayer, or shed tears.

The clergy of Scotland lent themselves to witch-finding with a zeal truly marvellous. They, in General Assembly, passed five condemnatory acts against witchcraft between the years 1640 and 1649. Kirk-sessions throughout the land outvied each other in their efforts to bring suspected witches to trial, and to counteract the dark deeds of Satan.

The Rev. John Scott, one of the Established Church ministers of Perth from 1762 to 1806, author of the History of the Earls of Gowrie and other works, left several folio manuscript volumes of extracts from the kirk-session records of Perth; and from these we make the following abbreviated selections in support of what is here stated:—

Lilias Adie, a Fife witch, obtained power from Satan to assist her and her friends, and to ruin her enemies. Like many other witches, she regularly attended the witch Sabbaths. How long she might have remained alive to strike terror into the hearts of the Torryburn people, none can tell, had not their worthy pastor, the Rev. Allan Logan, come to the rescue. Mr. Logan, report says, knew as well as any living man how to detect a witch. When "fencing" the sacramental table, he would look around him with his keen piercing eye, and call aloud, "You witch, begone from the holy communion table." The searching look and commanding voice made more than one woman retire from among the worthy communicants. Mr. Logan was well supported by a zealous kirk-session. This being so, Lilias Adie had little chance of escape. She and other suspected witches were submitted to a series of examinations and tests, which ended in her being burned within the sea-mark on the Fife coast.

From the ancient records of the kirk-session of Kirkcaldy, it seems that numerous reputed witches were burned in that town in the seventeenth century. In the year 1633 two witches were burned; the cost of their execution, including the price of tar barrels, and tow for tying the unfortunate beings at the stake, amounted to £2, 17s. 6d. Scots. One half of the sum was borne by the kirk-session, and the other half by the town. In the year 1649 a woman was burned on the estate of Burncastle, and the cost of watching her thirty days and of supplying fuel amounted to £92, 14s. Scots, a goodly sum in those days; but as £27, found in the possession of the reputed witch, was taken to assist in defraying the expenses of her judicial murder, the burden did not fall very heavy, after all, on the public.
