(Report of a conversation which Gerlach has had with Ex-Minister v. d. Decken on constitutional changes in Hanover, in which the King of Prussia should assist. The letter desires Bismarck to take up this matter, but first of all to write and give his opinion.) Another of the 28th of January. (For the present Bismarck is not to trouble himself about the Hanoverian affair. Opinion of Prokesch. Gerlach would like to have Bismarck in Berlin, as he fears grave crises, and, according to him, the people should be given clearly to understand that Bonapartism is our worst foe.... Bonaparte will direct his lust of conquest against Spain.) Finally, Gerlach’s letters on his conflict with Manteuffel. This conflict was clearly indicated in the letter of the 23rd of February, in which it is stated, _inter alia_, that Manteuffel had through Quehl taken a turn downwards, because he doubted the truth of what came to him from above; he wants to see the Conservative party destroyed, and he allows himself to be tempted by Quehl into secret opposition to Westphalen’s measures. Fourth Envelope. First half of the year 1854. Begins with an undated letter from Gerlach, probably written in January; it is followed by one from Manteuffel dated the 4th of January, while the remainder are mostly letters from the latter to Gerlach, together with reports by Bismarck, and finally, two letters of Seckendorff’s from Stuttgart, the second of which is dated the 27th of June. The following are of special interest. A note of the 17th of March, from the Prince of Prussia, asking Bismarck for information on the Eastern Question, and the reply thereto, a rather lengthy draft by Bismarck; then his report as to an interview which he had with the Prince at Baden, with the result that the latter yields to the royal will, though opposed to his own convictions; a letter from Bismarck to Gerlach on the Bamberg results; an exhaustive report by Bismarck on Buol’s view of the Eastern Question, which the former considers to be correct--doubtless addressed to Manteuffel; another report to the latter on the Bamberg Governments, Bismarck wanting apparently to keep them in check, and also respecting Bunsen and Gagern.
