For it being a stormy time, and persecution waxing hot, upon the Conventicle Act, through the busy boldness of hungry informers, who for their own advantage did not only themselves hunt after religious and peaceable meetings, but drove on the officers, not only the more inferior and subordinate, but in some places even the justices also, for fear of penalties, to hunt with them and for them; I found a pressure upon my spirit to write a small treatise to inform such officers how they might secure and defend themselves from being ridden by those malapert informers, and made their drudges. This treatise I called “A Caution to Constables and other inferior Officers concerned in the Execution of the Conventicle Act: with some Observations thereupon, humbly offered by way of Advice to such well-meaning and moderate Justices of the Peace as would not willingly ruin their peaceable Neighbours,” &c. This was thought to have some good service where it came upon such sober and moderate officers, as well justices as constables, &c., as acted rather by constraint than choice, by encouraging them to stand their ground with more courage and resolution against the insults of saucy informers. But whatever ease it brought to others, it brought me some trouble, and had like to have brought me into more danger, had not Providence wrought my deliverance by an unexpected way. For as soon as it came forth in print, which was in the year 1683, one William Ayrs, of Watford in Hertfordshire, a Friend, and an acquaintance of mine, who was both an apothecary and barber, being acquainted with divers of the gentry in those parts, and going often to some of their houses to trim them, took one of these books with him when he went to trim Sir Benjamin Titchborn of Rickmansworth, and presented it to him, supposing he would have taken it kindly, as in like cases he had formerly done. But it fell out otherwise. For he, looking it over after Ayrs was gone, and taking it by the wrong handle, entertained an evil opinion of it, and of me for it, though he knew me not. He thereupon communicated both the book and his thoughts upon it to a neighbouring justice, living in Rickmansworth, whose name was Thomas Fotherly, who concurring with him in judgment, they concluded that I should be taken up and prosecuted for it as a seditious book; for a libel they could not call it, my name being to it at length. Wherefore, sending for Ayrs, who had brought the book, Justice Titchborn examined him if he knew me, and where I dwelt; who telling him he knew me well, and had been often at my house, he gave him in charge to give me notice that I should appear before him and the other justice at Rickmansworth on such a day; threatening that if I did not appear, he himself should be prosecuted for spreading the book.
