"It seems to me, in the first place, that the selection of Genl. Dix is most wise and right in respect to the mutual relations of those who, acting generally with both these gentlemen, since the reunion of the party in 1849, would be divided in preference between them. On the first nomination of Gov. Seymour, in selecting a State candidate for the recent Presidential nomination--in choosing the two State delegates to the national convention on the renomination of Gov. Seymour--indeed, on most of the important occasions since the reunion, the radicals, while constituting far the larger and more effective element of that union, have conceded almost everything. The magnanimity with which they have done so, and the fidelity with which they have carried out the measures in which it has been done, have been strongly recognized by Gov. Marcy and his friends. These concessions have sometimes been not without dissatisfaction at the extent and frequent repetition of them; nor without large demand on the credit and patience of those who have been the means of inducing acquiescence in arrangements, in which, while one side contributed most of the capital of the partnership, the other received nearly its entire benefits. I feel some right to speak on this point without suspicion that I am swerved by personal associations from a fair judgment as respects all parties, as well from the general position I have held on these occasions as from the part I took in some of them. "It may not be improper to mention an instance. When the two State delegates to the national convention were to be chosen, Gov. Marcy, as desiring to be presented as the State candidate for the Presidency, and Gov. Seymour as a candidate before his own party the first time after his defeat before the people, felt their fortunes very deeply involved in the result. Gov. Marcy wrote to me requesting me to attend the meeting of the district delegates at Albany, and I did so. I never knew either of those gentlemen manifest more anxiety or having to confront more serious embarrassments. It had been the settled understanding that one Hunker and one radical should be taken for the State delegates. Most of the votes relied on to make the choice were radicals; and prominent men of that section, some of whom the radicals most desired to send, strongly wished to go. It seemed to Gov. Marcy necessary to take two Hunkers, but he felt the embarrassment of asking it, especially on the grounds that could alone be rendered; and others, who had to make the choice or were in firmer association with those who had to make it, were not easily convinced of the necessity or propriety of such a course. The difficulty was at length solved by our passing our favorite men and assenting to elect Mr. Seymour and another Hunker. Those of us who have, on this and other occasions, felt the strain with our own friends of keeping the elements of the union Democracy
