The notorious PRESTON, the cobbling politician, of Spa-fields’ memory, was also this day arrested on suspicion of being concerned in the plot, under a warrant issued by R. Birnie, Esq. It appears that the lodgings of this man were searched a few days before, but nothing of a suspicious nature was found. On those occasions he facetiously said--“his armory could not boast of a swan-shot, nor his port-folio of a scrap of paper of the slightest political interest.” Circumstances afterwards transpired which led to his arrest upon a charge of high treason. He was found industriously engaged in mending a shoe, with his family about him. He was surprised at this new visit, but submitted to his fate with cheerfulness, not unaccompanied by an apparent sense of his own importance. His daughters were highly indignant at this intrusion on their domestic privacy. The officers conducted their prisoner to Bow-street office, from whence he was sent to the Marquis of Anglesea public-house opposite. He was placed under the care of Lack, one of the patrol. He called for “a pipe and pot,” and, seating himself before the fire, seemed perfectly happy. He laughingly said to a gentleman who went to see him, that he thought “the farce would not be complete till he was taken.” He had previously denied all knowledge of the late conspiracy. After being shortly examined before Mr. Birnie, he was sent to Covent-garden watch-house, where he remained in confinement during that night. On the following morning he was removed from that place of confinement to the secretary of state’s office for the home department, where, at twelve o’clock, the Lords of the Council assembled, consisting of the Cabinet Ministers, the Marquis of Camden, Mr. Peel, Sir William Scott, Sir John Nicholls, Mr. Sturges Bourne, together with the Attorney and Solicitor-Generals, and other law officers. Mr. Buller, one of the principal clerks of the council, attended to take the minutes of the proceedings. When Preston was taken in before the Lords of the Council he behaved with his usual boldness and low insolence to most of their lordships personally. He called upon them with the most ludicrously impudent arrogance, and asked what they meant by sending for him to disturb his peace of mind, and to disturb the economy of his family, alluding to his three daughters binding shoes, and himself making them.
