Others, though content that treaties should be made in the mode proposed, are averse to their being the supreme law of the land. They insist, and profess to believe, that treaties like acts of assembly, should be repealable at pleasure. This idea seems to be new and peculiar to this country, but new errors, as well as new truths, often appear. These gentlemen would do well to reflect that a treaty is only another name for a bargain, and that it would be impossible to find a nation who would make any bargain with us, which should be binding on them absolutely, but on us only so long and so far as we may think proper to be bound by it.
