"The powers lodged in Congress are extensive; but it is presumed that they are not too extensive.  The first object of the constitution is to unite the states into one compact society, for the purpose of government.  If such a union must exist, or the states be exposed to foreign invasions, internal discord, reciprocal encrochments upon each other's property - to weakness and infamy, which no person will dispute; what powers must be collected and lodged in the supreme head or legislature of these states.  The answer is easy:  This legislature must have exclusive jurisdiction in all matters in which the states have a mutual interest.  There are some regulations in which the states are equally concerned - there are others, which in their operation, are limited to one state.  The first belong to congress - the last, to the respective legislatures.  No one state has the right to supreme control, in any affair in which the other states have an interest; nor should congress interfere in any affair which respects one state only."

"This question is of vast magnitude.  the states have very high ideas of their seperate sovereignty; altho' it is certain, that while each exists in it's full latitude, we can have no Federal Sovereignty.  However flattered each state may be by its independant sovereignty, we can have no union, no respectability, no national character, and what is more, no national justice, till the states resign to one supreme head power of legislating, judging and executing, in all matters of general nature."
