When the period arrives - come when it may - that this government will be compelled to resort to internal taxes for its support in time of peace, it will mark one of the most difficult and dangerous stages through which it is destined to pass.

The country is filled with energetic and enterprising men, rendered desperate by being reduced from affluence to poverty through the vicissitudes of the times. They will give an impulse to smuggling unknown to the country heretofore.

The danger in our system is that the general government, which represents the interests of the whole, may encroach on the states, which represent the peculiar and local interests, or that the latter may encroach on the former.

Be assured that, as certain as Congress transcends its assigned limits and usurps powers never conferred, or stretches those conferred beyond the proper limits, so surely will the fruits of its usurpation pass into the hands of the Executive. In seeking to become master, it but makes a master in the person of the President.

War, in our country, ought never to be resorted to but when it is clearly justifiable and necessary; so much so as not to require the aid of logic to convince our understanding nor the ardour of eloquence to inflame our passions. There are many reasons why this country should never resort to it but for causes the most urgent and necessary.

The day that the balance between the two sections of the country - the slaveholding States and the non-slaveholding States - is destroyed is a day that will not be far removed from political revolution, anarchy, civil war, and widespread disaster.

In 1828 we raised the duties, on an average, to nearly fifty per cent, when the debt was on the eve of being discharged, and thereby flooded the country with a revenue, when discharged, which could not be absorbed by the most lavish expenditures.

Protection and patriotism are reciprocal. This is the way which has led nations to greatness.

If not met promptly and decidedly, the two portions of the Union will gradually become thoroughly alienated, when no alternative will be left to us, as the weaker of the two, but to sever all political ties or sink down into abject submission.

In my opinion, any navy less than that which would give us the habitual command of our own coast and seas would be little short of useless.

We ought not to forget that the government, through all its departments, judicial as well as others, is administered by delegated and responsible agents; and that the power which really controls, ultimately, all the movements, is not in the agents, but those who elect or appoint them.

It is a fundamental rule with me not to vote for a loan or tax bill till I am satisfied it is necessary for the public service, and then not if the deficiency can be avoided by lopping off unnecessary objects of expenditure or the enforcement of an exact and judicious economy in the public disbursements.

There is but one nation on the globe from which we have anything serious to apprehend, but that is the most powerful that now exists or ever did exist. I refer to Great Britain.

I would rather be an independent senator, governed by my own views, going for the good of the country, uncontrolled by any thing which mortal man can bring to bear upon me, than to be president of the United States, put there as presidents of the United States have been for many years past.

Measures of policy are necessarily controlled by circumstances; and, consequently, what may be wise and expedient under certain circumstances might be eminently unwise and impolitic under different circumstances. To persist in acting in the same way under circumstances essentially different would be folly and obstinacy, and not consistency.

I hold that there is a mysterious connection between the fate of this country and that of Mexico; so much so that her independence and capability of sustaining herself are almost as essential to our prosperity and the maintenance of our institutions as they are to hers.

It has been lately urged in a very respectable quarter that it is the mission of this country to spread civil and religious liberty all over the globe, and especially over this continent - even by force, if necessary. It is a sad delusion.

None but a people advanced to a high state of moral and intellectual excellence are capable in a civilized condition of forming and maintaining free governments, and among those who are so far advanced, very few indeed have had the good fortune to form constitutions capable of endurance.

He is blind indeed who does not see, in the signs of the times, a strong tendency to plunge the Union as deep in debt as are many of the States, and to subjugate the whole to the paper system.

Every increase of protective duties is necessarily followed, in the present condition of our country, by an expansion of the currency, which must continue to increase till the increased price of production, caused by the expansion, shall be equal to the duty imposed, when a new tariff will be required.

I am aware how difficult is the task to preserve free institutions over so wide a space and so immense a population, but we are blessed with a Constitution admirably calculated to accomplish it. Its elastic power is unequaled, which is to be attributed to its federal character.

How can this full, perfect, just and supreme voice of the people, embodied in the Constitution, be brought to bear, habitually and steadily, in counteracting the fatal tendency of the government to the absolute and despotic control of the numerical majority?

There is not an example on record of any free state holding a province of the same extent and population without disastrous consequences. The nations conquered and held as a province have, in time, retaliated by destroying the liberty of their conquerors through the corrupting effect of extended patronage and irresponsible power.
