Wrote a long letter to Lord William Bentinck. I pressed upon him the necessity of making the home and the local authorities draw together. I told him he was suffering not for his obedience but for the disobedience of his predecessors. Assured him of support, lamented the _ungentlemanlike_ tone of society evidenced by the insult of the commanding officers to him, and by the publication of my private letter. I spoke in high terms of Lieut. W. Hislop's report on the opium arrangements (which on reflection I thought better than writing a letter to him), and I likewise spoke highly of Mr. Scott, the Commissioner in Assam. Acknowledged the Government could not have done otherwise than give up the opium treaties; but foretold a large falling off in the opium revenue from over-cultivation in Malwa. _January 3._ A letter from Clare on East Indian matters which I answered at length. Sent Prendergast's pamphlet to Jones. Read reports on the Delhi and Firuz Shah's canal, by which it appears my plan of joining the Sutlege and Jumna is not visionary. It has been done. The canal can still be traced. Delhi seems in distant times to have been like Milan, in the midst of canals. The grand canal sent a branch through the palace. The water has been again turned in the same channel. When the water flowed into Delhi on the opening of the canal on May 30, 1820, the people went out to meet it and threw flowers into the stream. In those countries nothing can be done without water, and with water, and such a sun, anything. _January 4, 1830._ Head Eraser's journey and finished it. It is very interesting, and shows how completely the Persian monarchy is falling to pieces. _January 5._ Saw Wrangham. There is no news. The affairs of the Netherlands, he says, look rather better, and Polignac is very stout and says he is very strong. It seems great complaints are made of Lord Stuart, who gives little information, and what little he does give is incorrect. _January 6._ Vesey Fitzgerald will certainly not be able to attend the House this year. His physicians say he would die in five minutes if he got up to speak. I heard G. Dawson tell the Duke to-day. I rather suspect G. Dawson would like Vesey's place. The Duke has been much occupied with the Greek question. I have not yet read any papers at the Foreign Office. He spoke to me of Bankes's going out, which he regretted.
