It is not as a reward that he will take upon him the mighty burden of this office, of which the toil and awful responsibility whiten the statesman’s head, and in which, as in more than one instance we have seen, the warrior encounters a deadlier risk than in the battle-field. When General Pierce received the news of his nomination, it affected him with no thrill of joy, but a sadness, which, for many days, was perceptible in his deportment. It awoke in his heart the sense of religious dependence--a sentiment that has been growing continually stronger, through all the trials and experiences of his life; and there was nothing feigned in that passage of his beautiful letter, accepting the nomination, in which he expresses his reliance upon heavenly support. The committee, appointed by the Baltimore convention, conveyed to him the intelligence of his nomination in the following terms:-- “A national convention of the democratic republican party, which met at Baltimore on the first Tuesday in June, unanimously nominated you as a candidate for the high trust of the President of the United States. We have been delegated to acquaint you with the nomination, and earnestly to request that you will accept it.

To these we respectfully invite your attention. “It is firmly believed that to your talents and patriotism the security of our holy Union, with its expanded and expanding interests, may be wisely trusted, and that, amid all the perils which may assail the Constitution, you will have the heart to love and the arm to defend it.” We quote likewise General Pierce’s reply:--
