working harmoniously and efficiently under such circumstances, have a right to be heard when we express the conviction that the present is a fit time for Gov. Marcy and his friends to evince some mutuality in their relations towards the radicals; and that a more safe, proper, and unobjectionable opportunity to reciprocate the magnanimity with which they have been treated cannot be offered than in assenting to the selection of Genl. Dix for the Cabinet. Such I believe to be the general sense of those who have formed four-fifths of the majorities in our State conventions and elsewhere since the reunion of the party from which Gov. Marcy and Gov. Seymour have received support. "Regarding the question simply as it affects the party in this State, I think it highly desirable and important that the occasion should be embraced to manifest that mutuality towards the radicals without which the elements of a party cannot be kept in cordial or lasting union, and I think that, on such a question, the general sense of fair men is more wisely conformed to than disregarded. Certainly I do not mean to censure Gov. Marcy for allowing his name to be presented, or that we have any right or disposition to limit the range of selection by Genl. Pierce; but simply to state considerations which, in my judgment, are important in deciding the choice. "This brings me to the question how the party in New York, as a whole, stand affected as between these two gentlemen? The radicals, who are a full majority in numbers and more in efficiency, are for Gen. Dix, and would, under the circumstances, feel some sense of exclusion in a choice of a different nature. Gov. Marcy and his personal friends, though preferring him, cannot, as the case stands, make any actual opposition to the appointment of Gen. Dix; and, if it be made, will acquiesce--most, if not all of them, with cordiality. The considerations I have alluded to appeal strongly to their judgment and sense of justice, if failing to change their wishes; and with the relations which have grown up with many who are for Genl. Dix, secure this result. The opposition of the extreme Hunkers to Marcy or Dix will be most manifest towards the one appearing most likely at the moment to be appointed; but I think that they are generally less repugnant to the selection of Dix, towards whom there is less of violence and bitterness in individual leaders. So far as this may be supposed to arise from the part Gov. Marcy took in promoting the union of the party, I regard it as a merit; and for that, with a friendly construction of acts and motives, we have handsomely acquitted ourselves towards him. This animosity has other causes, among which is that he has been in the way of other gentlemen who have grown faster in their own esteem than in his appreciation (in which difference I think he is more right than they); and especially that Mr. Dickinson regards him as having, by being a candidate for the Presidency, kept that distinction
