First State of the Union Address-Thomas Jefferson (1801)

Agriculture, manufactures, commerce, and navigation, the four pillars of our prosperity, are then most thriving when left most free to individual enterprise. Protection from casual embarrassments, however, may sometimes be seasonably interposed. If in the course of your observations or inquiries they should appear to need any aid within the limits of our constitutional powers, your sense of their importance is a sufficient assurance they will occupy your attention. We can not, indeed, but all feel an anxious solicitude for the difficulties under which our carrying trade will soon be placed. How far it can be relieved, otherwise than by time, is a subject of important consideration.
