The seizure of the mails was doubtless due to a desire on the part of the Council to discover such persons as might be holding correspondence with the enemy. The vigilance of the Council continued, for, on 4th December, the Deputy Governor of Dover was required to examine the master of the post barque, lately come over, as to his bringing a person who (as he had been previously informed) "was dangerous, and brought commissions and letters from the enemy." And, again, on the 13th May 1651, the Council of State gave order to the Committee of Examinations, "to inquire into the opening of Capt. Bishop's letter between England and Scotland, and to write such persons as they think fit for the discovery of the same. The Attorney-General to bring in a list of the persons employed as postmasters upon the several roads throughout this nation, with their character." "To write the Lord General to cause an inquiry to be made after the persons who presumed to break open some letters directed to him, and, if he finds any of them to be near the southern parts, he is to give notice thereof to Council, that they may prosecute them." Again, on the 21st August 1651, the Council gave directions that "the packet brought in this day from the northern parts be searched before the letters be delivered out." These are specimens of the measures taken at the period in question with the view of preventing the post-office service being used in the interest of the King's party. On the 10th March 1651, the Council of State gave order for the revival of a Committee, which was set up the year before, to consider the business of the Foreign Post. They were to send for Mr. Witherings and "confer with him as to what money he had on hand that was formerly wont to be paid to the Earl of Warwick." It is not clear whether this inquiry had reference to any supposed irregularity on Witherings' part, or merely to the question of moneys claimed by the earl. Be this as it may, a fresh storm was soon to break over Witherings' head. In the month of June 1651, the charges of delinquency of which he had been acquitted in 1649 were levelled at him in an aggravated form. The information laid against him was to the effect "that when Oxford was a King's garrison, he compounded with delinquents, and paid moneys for them, by order of Sir Edw. Sydenham. That in the Essex insurrection he sent a man and horse to Lord Goring, and was in person at Bow Bridge when held by the enemy. That he was at many private meetings at the Hoope Tavern, Leadenhall Street, plotting about the revolt of Capt. Batten and the fleet (1648). That he conveyed moneys into France for the relief of Cavaliers, some of which was taken. That he concealed an annuity of £1200, and several sums due to the State which are in his custody, and paid several sums to Sir Edw. Sydenham, a delinquent, contrary to the Order of the Council of State. That he is very familiar with delinquents, stands bound for them, conceals their letters,
