DEAR SIR,--I wrote you last on the 21st. Yours of the 12th, therein acknowledged, is the last received. The measure I suggested in mine, of adjourning for consultation with their constituents, was not brought forward; but on Tuesday three resolutions were moved, which you will see in the public papers. They were offered in committee, to prevent their being suppressed by the previous question, and in the committee on the state of the Union, to put it out of their power, by the rising of the committee and not sitting again, to get rid of them. They were taken by surprise, not expecting to be called to vote on such a proposition as "that it is inexpedient to resort to war against the French republic." After spending the first day in seeking on every side some hole to get out at, like an animal first put into a cage, they gave up their resource. Yesterday they came forward boldly, and openly combated the proposition. Mr. Harper and Mr. Pinckney pronounced bitter philippics against France, selecting such circumstances and aggravations as to give the worst picture they could present. The latter, on this, as in the affair of Lyon and Griswold, went far beyond that moderation he has on other occasions recommended. We know not how it will go. Some think the resolution will be lost, some, that it will be carried; but neither way, by a majority of more than one or two. The decision of the Executive, of two-thirds of the Senate, and half the House of Representatives, is too much for the other half of that House. We therefore fear it will be borne down, and are under the most gloomy apprehensions. In fact, the question of war and peace depends now on a toss of cross and pile. If we could but gain this season, we should be saved. The affairs of Europe would of themselves save us. Besides this, there can be no doubt that a revolution of opinion in Massachusetts and Connecticut is working. Two whig presses have been set up in each of those States. There has been for some days a rumor, that a treaty of alliance, offensive and defensive with Great Britain, has arrived. Some circumstances have occasioned it to be listened to; to wit, the arrival of Mr. King's secretary, which is affirmed, the departure of Mr. Liston's secretary, which I know is to take place on Wednesday next, the high tone of the executive measures at the last and present session, calculated to raise things to the unison of such a compact, and supported so desperately in both Houses in opposition to the pacific wishes of the people, and at the risk of their approbation at the ensuing election. Langdon yesterday, in debate, mentioned this current report. Tracy, in reply, declared he knew of no such thing, did not believe it, nor would be its advocate.
