Amendment X: James Monroe, Views of the President of the United States on the Subject of Internal Improvements This is an article that was written by James Monroe's giving his opinion on the tenth amendment of the constitution.
From the site:
Having presented above a full view of all the powers granted to the United States, it will be proper to look to those remaining to the States. It is by fixing the great powers which are admitted to belong to each government that we may hope to come to a right conclusion respecting those in controversy between them. In regard to the National Government, this task was easy because its powers were to be found in specific grants in the Constitution; but it is more difficult to give a detail of the powers of the State governments, as their constitutions, containing all powers granted by the people not specifically taken from them by grants to the United States, can not well be enumerated. Fortunately, a precise detail of all the powers remaining to the State governments is not necessary in the present instance. A knowledge of their great powers only will answer every purpose contemplated, and respecting these there can be no diversity in opinion. They are sufficiently recognized and established by the Constitution of the United States itself. In designating the important powers of the State governments it is proper to observe, first, that the territory contemplated by the Constitution belongs to each State in its separate character and not to the United States in their aggregate character. Each State holds territory according to its original charter, except in cases where cessions have been made to the United States by individual States. The United States had none when the Constitution was adopted which had not been thus ceded to them and which they held on the conditions on which such cession had been made. Within the individual States it is believed that they held not a single acre; but if they did it was as citizens held it, merely as private property. The territory acquired by cession lying without the individual States rests on a different principle, and is provided for by a separate and distinct part of the Constitution. It is the territory within the individual States to which the Constitution in its great principles applies, and it applies to such territory as the territory of a State and not as that of the United States. The next circumstance to be attended to is that the people composing this Union are the people of the several States, and not of the United States in the full sense of a consolidated government. The militia are the militia of the several States; lands are held under the laws of the States; descents, contracts, and all the concerns of private property, the administration of justice, and the whole criminal code, except in the cases of breaches of the laws of the United States made under and in conformity with the powers vested in Congress and of the laws of nations, are regulated by State laws. This enumeration shows the great extent of the powers of the State governments. The territory and the people form the basis on which all governments are founded. The militia constitutes their effective force. The regulation and protection of property and of personal liberty are also among the highest attributes of sovereignty. This, without other evidence, is sufficient to show that the great office of the Constitution of the United States is to unite the States together under a Government endowed with powers adequate to the purposes of its institution, relating, directly or indirectly, to foreign concerns, to the discharge of which a National Government thus formed alone could be competent.
