An instance of such a proceeding is given by Williams in his history of Watford, where the destinies of the post were, at the time, presided over by a postmistress. "In response," says he, "to the thundering knock of the conductor, the old lady left her couch, and thrusting her head, covered with a wide bordered night-cap, out of the bedroom window, let down the mail bag by a string, and quickly returned to her bed again." Coming thus nightly to the open window in her night dress could not have been without its risks to a delicate creature like the postmistress. These postmasters required looking after occasionally, however, for they sometimes did wrong. In 1668 the postmaster of Edinburgh got into trouble by levying charges of 1d., 2d., or 3d. upon letters over and above the proper rates, and he was peremptorily ordered to discontinue the practice. [Illustration: The Postmistress of Watford despatching the Mail.] They also, it would appear, exercised some sort of surveillance over private correspondence. Chambers, in his 'Domestic Annals of Scotland,' to which valuable work we are again indebted, gives a case in point: "In July 1701, two letters from Brussels, _having the cross upon the back of them_, had come with proper addresses under cover to the Edinburgh postmaster. He _was surprised with them_, and brought them to the Lord Advocate, who, however, on opening them, found they were of no value, being only on private business; wherefore he ordered them to be delivered by the postmaster to the persons to whom they were directed." Yet zeal for the King's interest did not always have an acceptable reward, as is shown by the Scotch Privy Council Record of 1679. The keeper of the Edinburgh letter-office was accused of "sending up a _bye-letter_ with the flying packet upon the twenty-two day of June last, giving ane account to the postmaster of England of the defeat of the rebels in the west, which was by the said postmaster communicated to the King before it could have been done by his Majesty's Secretary for Scotland, and which letter contains several untruths in matter of fact." For having forestalled his Majesty's Secretary, probably, rather than for the inaccuracy as to facts, the keeper of the post was sent to the Tolbooth, there to meditate upon the unprofitableness of official zeal, during the Council's pleasure.
