Thus matters stood when, early in 1792, in consequence of some discrepancies in the accounts, the postmasters-general determined that letters for the city by the first or morning delivery should be checked. Care had been taken that the check should not be of a nature to retard the delivery; and yet, strangely enough, the delivery became later and later every day. At length a public advertisement appeared inviting the merchants and traders to meet at the London Tavern on Wednesday the 15th February in order to consider the subject. The meeting was held under the presidency of Alderman Curtis, one of the members of Parliament for the city; and strong resolutions were passed directing the postmaster-generals' attention to the delay, and calling upon them to explain and remove the cause. Charles Bonnor, the deputy comptroller-general, owed all he possessed to Palmer. It was by Palmer that he had been brought into the Post Office in July 1784, and the same influence procured for him shortly afterwards a salary of £500 and an allowance of £150 a year for a house. Warm in his attachments as he was fierce in his animosities, the great reformer extended to Bonnor a confidence which probably no other man possessed, and during his frequent absences from London kept up with him a correspondence in which he poured out his inmost thoughts. This person, stung with jealousy at some fancied coolness on Palmer's part, now published a pamphlet in which he charged his friend and benefactor with wilfully delaying the delivery of the morning letters, and then promoting the meeting at the London Tavern in order to protest against a mischief of his own making. According to Bonnor, Palmer had spared no effort to induce persons to attend the meeting, and had furnished Alderman Curtis, the chairman, with materials for denouncing the Post Office. All this, it was alleged, had been done in order to bring the postmasters-general into discredit, and to create a demand that Palmer might have larger powers given him and be left to deal with Post Office matters according to his unfettered judgment.
