Arbuthnot said that Canning and Castlereagh had always gone on well together after their reconciliation, but that Lord Liverpool's subjection to him arose more from fear than affection. Liverpool told Arbuthnot that he earnestly desired to resign his office, that his health was broken, and he was only retained by the consideration that his retirement might be the means of breaking up a Government which he had (through the kindness of his colleagues to him) been enabled to hold together; that Canning worked with a twenty-horse power; that his sensitiveness was such that he [Canning] felt every paragraph in a newspaper that reflected on him, and that the most trifling causes produced an irritation on his mind, which was always vented upon him (Lord Liverpool), and that every time the door was opened he dreaded the arrival of a packet from Canning. Arbuthnot had been in great favour with the King, who talked to him and consulted him, but he nearly cut him after the disunion consequent on Canning's appointment. Knighton came to Arbuthnot and desired him to try and prevail on the Duke to consent to Canning's being Prime Minister, which he told him was useless, and from that time the King was just civil to the Duke and that was all. The Duke had always suspected that Canning wanted all along to be Prime Minister, and that when he sent him to Russia to congratulate Nicholas it was to get him out of the way, and he was the more convinced because Canning proposed to him to go on to Moscow for the coronation, which he positively refused, having promised his friends to be back in April, which he accordingly was. Canning never had a great opinion of Huskisson, nor really liked him, though he thought him very useful from being conversant with the subjects on which he was himself most ignorant--trade and finance; but he did not contemplate his being in the Cabinet, and had no confidence in his judgment or his discretion; and this tallies with what Lady Canning told me, though certainly he did not do Huskisson justice in any way, which Arbuthnot admitted. Knighton behaved exceedingly well during the King's illness, and by the vigilant watch he kept over the property of various kinds prevented the pillage which Lady Conyngham would otherwise have made. She knew everything, but did not much trouble herself about affairs, being chiefly intent upon amassing money and collecting jewels.
