My dear Duke of Wellington,--I believed it to be so generally understood, that the king usually intrusts the formation of an administration to the individual whom it is his majesty's gracious intention to place at the head of it; that it did not occur to me, when I communicated to your Grace yesterday the commands which I had just received from his majesty, to add, that, in the present instance, his majesty does not intend to depart from the usual course of proceeding on such occasions. I am sorry to have delayed some hours this answer to your Grace's letter; but from the nature of the subject, I did not like to forward it without having previously submitted it (together with your Grace's letter) to his Majesty. Ever, my dear Duke of Wellington, your Grace's sincere and faithful servant, GEORGE CANNING. And finally, on the evening of the same day, the Duke wrote thus to Mr. Canning.-- London, April 11, 1837. My dear Mr. Canning,--I have received your letter of this day, and I did not understand the one of yesterday evening as you explained it to me. I understood from yourself that you had in contemplation another arrangement, and I do not believe that the practice to which you refer has been so invariable as to enable me to affix a meaning to your letter which its words did not, in my opinion, convey. I trust that you will have experienced no inconvenience from the delay of this answer, which I assure you has been occasioned by my desire to discover a mode by which I could continue united with my recent colleagues.--I sincerely wish that I could bring my mind to the conclusion that, with the best intentions on your part, your government could be conducted practically on the principles of that of Lord Liverpool; that it would be generally so considered; or that it would be adequate to meet our difficulties, in a manner satisfactory to the king, or conducive to the interests of the country. As, however, I am convinced that these principles must be abandoned eventually, that all our measures would be viewed with suspicion by the usual supporters of the government; that I could do no good in the cabinet; and that at last I should be obliged to separate myself from it, at the moment at which such separation would be more inconvenient to the king's service than it can be at present, I must beg you to request his majesty to excuse me from belonging to his councils. Ever, my dear Mr. Canning, yours most sincerely, WELLINGTON. This closed the correspondence; and it is needless to add that the Duke continued to hold aloof from the new administration.
