In 1642 Parliament appears to have been especially pitiless, dispensing fines and imprisonments right and left upon any one who displeased it. Sir Edward Dering was impeached for promoting a petition from the county of Kent, and the petition itself was ordered to be burnt at the hands of the common hangman. Sir Ralph Hopton was imprisoned in the Tower for saying in the House that his fellow-members seemed to ground their views of the King's apostacy upon evidence insufficient to convict a horse-thief; and a wretched tradesman named Sandeford, who cursed Parliament and all its works, was fined a hundred marks, pilloried, whipped, and sentenced to life-long confinement in a House of Correction. So assertive of their power and so jealous of their privileges were the Commons at this time that they even made an order to issue a warrant for the apprehension of all such persons as one of their members, Sir Walter Erie, should name.[268] [268] Sir Walter had lodged information of scandalous words spoken by certain individuals. See Lister's "Life of Clarendon," vol. iii. p. 125. Peers and prelates were no safer than the humbler members from the vindictive spirit of Parliament, and any breach of its privileges on their part brought instant punishment. In 1603 the Bishop of Bristol published a book which was considered by Parliament to be most offensive. At a conference of both Houses he was sternly rebuked "for presuming to see more than a Parliament could," when he at once recanted, withdrew his obnoxious presumptions, and declared, "first, that he had erred; secondly, that he was sorry for it; and, thirdly, that if it were to do again, he would not do it."[269] Only on these abject terms could he expiate his offence. A hundred years later, in 1712, a volume of sermons written by the Bishop of St. Asaph, deploring the terms of the peace with France and Spain, was condemned to be burnt in Palace Yard.

All warrants issued by the House are executed by him. He brings witnesses and culprits to the bar, sees that members and strangers do not infringe its resolutions, and has the custody of such persons as may be committed to his charge. The doorkeepers, messengers, and police employed in the Commons are under his control, as are the buildings themselves while Parliament is sitting. As an officer of the Crown, he may be summoned to attend upon the sovereign on such occasions as the opening of Parliament, when the Deputy Sergeant-at-Arms takes his place as the personal escort of the Speaker. Like his colleagues, the Sergeant used formerly to eke out a precarious living upon fees, and received all or a part of the fines inflicted upon members for absence or unpunctuality. To-day, however, he enjoys a regular salary, and an official residence.[270]
