Federal Sphere

Hamilton stated in "The Federalist" No. 82:

"The principles established in a former paper teach us, that the states will retain all pre-existing authorities, which may not be exclusively delegated to the federal head; and that this exclusive jurisdiction can only exist in one of three cases; where an exclusive authority is in express terms granted to the union; or where a particular authority is granted to the union, and the exercise of a like authority is prohibited to the states, or where an authority is granted to the union with which a similar authority in the states would be utterly incompatible..."

In "The Federalist No. 17" Hamilton states:

"...The regulation of the mere domestic police of a State appears to me to hold out slender allurements to [federal] ambition. Commerce, finance, negotiation and war seem to comprehend all the objects, which have charms for minds governed by that passion [ambition]; and all the powers necessary to these objects ought in the first instance to be lodged in the national depository. The administration of private justice between the citizens of the same State, the supervision of agriculture and of other concerns of a similar nature, all those things in short which are proper to be provided for by local legislation, can never be desirable cares of a general [federal] jurisdiction..."
