SIR: The House of Representatives, calling to mind the blessings enjoyed by the people of the United States, and especially the happiness of living under constitutions and laws which rest on their authority alone, could not learn with other emotions than those you have expressed that any part of our fellow-citizens should have shewn themselves capable of an insurrection. And we learn with the greatest concern that any misrepresentations whatever of the Government and its proceedings, either by individuals or combinations of men, should have been made and so far credited as to foment the flagrant outrage which has been committed on the laws. We feel with you the deepest regret at so painful an occurrence in the annals of our country. As men regardful of the tender interests of humanity, we look with grief at scenes which might have stained our land with civil blood; as lovers of public order, we lament that it has suffered so flagrant a violation; as zealous friends of republican government, we deplore every occasion which in the hands of its enemies may be turned into a calumny against it. This aspect of the crisis, however, is happily not the only one which it presents. There is another, which yields all the consolations which you have drawn from it. It has demonstrated to the candid world, as well as to the American people themselves, that the great body of them everywhere are equally attached to the luminous and vital principle of our Constitution, which enjoins that the will of the majority shall prevail; that they understand the indissoluble union between true liberty and regular government; that they feel their duties no less than they are watchful over their rights; that they will be as ready at all times to crush licentiousness as they have been to defeat usurpation. In a word, that they are capable of carrying into execution that noble plan of self-government which they have chosen as the guaranty of their own happiness and the asylum for that of all, from every clime, who may wish to unite their destiny with ours. These are the just inferences flowing from the promptitude with which the summons to the standard of the laws has been obeyed, and from the sentiments which have been witnessed in every description of citizens in every quarter of the Union. The spectacle, therefore, when viewed in its true light, may well be affirmed to display in equal luster the virtues of the American character and the value of republican government. All must particularly acknowledge and applaud the patriotism of that portion of citizens who have freely sacrificed everything less dear than the love of their country to the meritorious task of defending its happiness.
