We have assembled to celebrate the accomplishment of this undertaking, and to indulge afresh in the recollection of the great event which it is designed to commemorate. Eighteen years, more than half the ordinary duration of a generation of mankind, have elapsed since the cornerstone of this monument was laid. The hopes of its projectors rested on voluntary contributions, private munificence, and the general favor of the public. These hopes have not been disappointed. Donations have been made by individuals, in some cases of large amount, and smaller sums have been contributed by thousands. All who regard the object itself as important, and its accomplishment, therefore, as a good attained, will entertain sincere respect and gratitude for the unwearied efforts of the successive presidents, boards of directors, and committees of the Association which has had the general control of the work. The architect, equally entitled to our thanks and commendation, will find other reward, also, for his labor and skill, in the beauty and elegance of the obelisk itself, and the distinction which, as a work of art, it confers upon him. At a period when the prospects of further progress in the undertaking were gloomy and discouraging, the Mechanic Association, by a most praiseworthy and vigorous effort, raised new funds for carrying it forward, and saw them applied with fidelity, economy, and skill. It is a grateful duty to make public acknowledgments of such timely and efficient aid. The last effort and the last contribution were from a different source. Garlands of grace and elegance were destined to crown a work which had its commencement in manly patriotism. The winning power of the sex addressed itself to the public, and all that was needed to carry the monument to its proposed height, and to give to it its finish, was promptly supplied. The mothers and the daughters of the land contributed thus, most successfully, to whatever there is of beauty in the monument itself, or whatever of utility and public benefit and gratification there is in its completion.
