It does not appear, however, as if anything could have been done, for Canning was bent upon being Prime Minister; and I asked Arbuthnot to what the Duke would have consented, and he said, 'Not to that,' that after the transaction with the Whigs he could not have felt sufficient confidence in Canning to agree to his being Prime Minister. (If he distrusted Canning he ought to have refused to act with him at all, not merely objected to his being Prime Minister, but the ground of his objection was shifted.) Originally the King could not bear Canning, and he was only persuaded by the Duke to take him into the Cabinet. Afterwards he was so offended at the influence he acquired there, and particularly with that which he had got over the mind of Lord Liverpool, that he one day sent for Arbuthnot and desired him to tell Lord Liverpool that he could not endure to see Canning make a puppet of him, and he would rather he was Prime Minister at once than have all the power without the name by governing him (Lord Liverpool) as he pleased, and that unless he could shake off this influence he was determined not to let him continue at the head of the Government, and, moreover, he must find some means of getting rid of Canning altogether. This Arbuthnot wrote to Lord Liverpool, who wrote an answer couched in terms of indignation, saying he by no means coveted his situation, that he was sure his colleagues would resent any indignity offered to him, and that the King had better take care what he was about, and not, by producing disunion in the Government, incur the risk of making the end of his reign as disastrous as the beginning of it had been prosperous. Not very long after Canning got into favour, and in this way:--Harriet Wilson at the time of her connexion with Lord Ponsonby got hold of some of Lady Conyingham's letters to him, and she wrote to Ponsonby, threatening, unless he gave her a large sum, to come to England and publish everything she could. This produced dismay among all the parties, and they wanted to get Ponsonby away and to silence the woman. In this dilemma Knighton advised the King to have recourse to Canning, who saw the opening to favour, jumped at it, and instantly offered to provide for Ponsonby and do anything which could relieve the King from trouble. Ponsonby was sent to Buenos Ayres forthwith, and the letters were bought up. From this time Canning grew in favour, which he took every means to improve, and shortly gained complete ascendancy over the King. [Page Head: CANNING AND THE LIVERPOOL ADMINISTRATION.]
