I return to you the letter of Mr Fallon respecting Cuba , which you enclosed to me for my perusal.1 From what I had before learned from an Official source, the information which Mr F. gives, did not surprise me.

The result of the late election in Pennsylvania was unexpected, though I am far from believing that the state will be lost to the Democracy in November. I have not heretofore regarded the success of the Democratic party in the Presidential election as doubtful, or that any thing was likely to happen to make it so. If however the great state of Pennsylvania, should give way, and vote with our opponents we may be defeated. Can this be possible? Will you give me your opinion on the subject? I am aware of the embarrassment which is produced in some of the Northern States, by the secession of a few prominent democrats, and their Union with the Abolitionists, under the more popular name, of the advocates of free soil, but I had hoped and believed there were but few such in the staunch old Democratic state of Pennsylvania. Surely these Democratic leaders must now see, that the only effect of further persisting in their course, must be not to advance their own single idea, but to aid the Whigs to overthrow the Democratic party and policy. If they persist in their course, the effect will be the same as if they were to vote for the Whig candidate. Some of them I know are ready to go this length, to gratify their personal revenge upon the Democratic party, for failing to apprciate, as they think they should have done, their merits, but I hope there are very few of this class. My attention was called a few days ago to a statement of a letter-writer in a New York Barn burner paper, to the effect that my old friends Judge Kane and Mr Horn were in favour of the free soil ticket as it is called. I could not believe the statement & hope it is not true. They have always been democrats, and though they may retain strong personal attachments for Mr V-B. , they surely cannot on that account, be willing to see, the great principles and the policy they have so long approved & supported, reversed and over-turned, as it would be, by the defeat of the Democratic candidates in this election. With kind salutations to Mrs. Dallas and your daughters: . . . .
