"What is to be our future, I do not know. I have no taste for indulging in speculations about it. I would not, if I could, raise the veil that wisely conceals it from us. 'Sufficient unto the day is the evil thereof,' is a good precept in everything pertaining to human action. The evil I would not anticipate; I would rather strive to prevent its coming; and one way, in my judgment, to prevent it, is, while here, in all things to do what is right and proper to be done under the Constitution of the United States; nothing more, and nothing less. Our safety, as well as the prosperity of all parts of the country, so long as this government lasts, lies mainly in a strict conformity to the laws of its existence. Growth is one of these. The admission of new States, is one of the objects expressly provided for. How are they to come in? With just such constitutions as the people in each may please to make for themselves, so it is republican in form. This is the ground the South has ever stood upon. Let us not abandon it now. It is founded upon a principle planted in the compact of Union itself; and more essential to us than all others besides; that is, the equality of the States, and the reserved rights of the people of the respective States. By our system, each State, however great the number, has the absolute right to regulate all its internal affairs as she pleases, subject only to her obligations under the Constitution of the United States. With this limitation, the people of Massachusetts have the perfect right to do as they please upon all matters relating to their internal policy; the people of Ohio have the right to do the same; the people of Georgia the same; of California the same; and so with all the rest.
