The mighty pyramid itself, half buried in the sands of Africa, has nothing to bring down and report to us, but the power of kings and the servitude of the people. If it had any purpose beyond that of a mausoleum, such purpose has perished from history and from tradition. If asked for its moral object, its admonition, its sentiment, its instruction to mankind, or any high end in its erection, it is silent; silent as the millions which lie in the dust at its base, and in the catacombs which surround it. Without a just moral object, therefore, made known to man, though raised against the skies, it excites only conviction of power, mixed with strange wonder. But if the civilization of the present race of men, founded, as it is, in solid science, the true knowledge of nature, and vast discoveries in art, and which is elevated and purified by moral sentiment and by the truths of Christianity, be not destined to destruction before the final termination of human existence on earth, the object and purpose of this edifice will be known till that hour shall come. And even if civilization should be subverted, and the truths of the Christian religion obscured by a new deluge of barbarism, the memory of Bunker Hill and the American Revolution will still be elements and parts of the knowledge which shall be possessed by the last man to whom the light of civilization and Christianity shall be extended. This celebration is honored by the presence of the chief executive magistrate of the Union. An occasion so national in its object and character, and so much connected with that Revolution from which the government sprang at the head of which he is placed, may well receive from him this mark of attention and respect. Well acquainted with Yorktown, the scene of the last great military struggle of the Revolution, his eye now surveys the field of Bunker Hill, the theatre of the first of those important conflicts. He sees where Warren fell, where Putnam, and Prescott, and Stark, and Knowlton, and Brooks fought. He beholds the spot where a thousand trained soldiers of England were smitten to the earth, in the first effort of revolutionary war, by the arm of a bold and determined yeomanry, contending for liberty and their country. And while all assembled here entertain towards him sincere personal good wishes and the high respect due to his elevated office and station, it is not to be doubted that he enters, with true American feeling, into the patriotic enthusiasm kindled by the occasion which animates the multitudes that surround him. His Excellency, the Governor of the Commonwealth, the Governor of Rhode Island, and the other distinguished public men whom we have the honor to receive as visitors and guests to-day, will cordially unite in a celebration connected with the great event of the Revolutionary war.
