A representative of the United States must be of the age of twenty-five years; must have been seven years a citizen of the United States; must, at the time of his election, be an inhabitant of the State he is to represent; and, during the time of his service, must be in no office under the United States. Under these reasonable limitations, the door of this part of the federal government is open to merit of every description, whether native or adoptive, whether young or old, and without regard to poverty or wealth, or to any particular profession of religious faith.
