Below is the first part of President John Adams 4th State of the Union message to Congress. In the message he welcomes Congress to the new, permanent seat of government in the District of Columbia and warns them of their duty to provide for the citizens.
Gentlemen of the Senate and Gentlemen of the House of Representatives:
Immediately after the adjournment of Congress at their last session in Philadelphia I gave directions, in compliance with the laws, for the removal of the public offices, records, and property. These directions have been executed, and the public officers have since resided and conducted the ordinary business of the Government in this place.
I congratulate the people of the United States on the assembling of Congress at the permanent seat of their Government, and I congratulate you, gentlemen, on the prospect of a residence not to be changed. Although there is cause to apprehend that accommodations are not now so complete as might be wished, yet there is great reason to believe that this inconvenience will cease with the present session.
It would be unbecoming the representatives of this nation to assemble for the first time in this solemn temple without looking up to the Supreme Ruler of the Universe and imploring His blessing.
May this territory be the residence of virtue and happiness! In this city may that piety and virtue, that wisdom and magnanimity, that constancy and self-government, which adorned the great character whose name it bears be forever held in veneration! Here and throughout our country may simple manners, pure morals, and true religion flourish forever!
It is with you, gentlemen, to consider whether the local powers over the District of Columbia vested by the Constitution in the Congress of the United States shall be immediately exercised. If in your opinion this important trust ought now to be executed, you can not fail while performing it to take into view the future probable situation of the territory for the happiness of which you are about to provide. You will consider it as the capital of a great nation advancing with unexampled rapidity in arts, in commerce, in wealth, and in population, and possessing within itself those energies and resources which, if not thrown away or lamentably misdirected, will secure to it a long course of prosperity and self-government.
