This is an unaccustomed spectacle. For the first time, fellow-citizens, badges of mourning shroud the columns and overhang the arches of this hall. These walls, which were consecrated, so long ago, to the cause of American liberty, which witnessed her infant struggles, and rung with the shouts of her earliest victories, proclaim, now, that distinguished friends and champions of that great cause have fallen. It is right that it should be thus. The tears which flow, and the honors that are paid, when the founders of the republic die, give hope that the republic itself may be immortal. It is fit that, by public assembly and solemn observance, by anthem and by eulogy, we commemorate the services of national benefactors, extol their virtues, and render thanks to God for eminent blessings, early given and long continued, through their agency, to our favored country. ADAMS and JEFFERSON are no more; and we are assembled, fellow-citizens, the aged, the middle-aged, and the young, by the spontaneous impulse of all, under the authority of the municipal government, with the presence of the chief magistrate of the Commonwealth, and others its official representatives, the University, and the learned societies, to bear our part in those manifestations of respect and gratitude which pervade the whole land. ADAMS and JEFFERSON are no more. On our fiftieth anniversary, the great day of national jubilee, in the very hour of public rejoicing, in the midst of echoing and reëchoing voices of thanksgiving, while their own names were on all tongues, they took their flight together to the world of spirits. If it be true that no one can safely be pronounced happy while he lives, if that event which terminates life can alone crown its honors and its glory, what felicity is here! The great epic of their lives, how happily concluded! Poetry itself has hardly terminated illustrious lives, and finished the career of earthly renown, by such a consummation. If we had the power, we could not wish to reverse this dispensation of the Divine Providence. The great objects of life were accomplished, the drama was ready to be closed. It has closed; our patriots have fallen; but so fallen, at such age, with such coincidence, on such a day, that we cannot rationally lament that that end has come, which we knew could not be long deferred.
