"If the people in Britain knew the nature and disposition of the New England people as well as we do they would not find so many friends in England as I suppose they do"

This quote by Nathaniel Smith suggests that the people of New England have particular qualities or attributes that may not be well understood by the people of Britain. Smith seems to imply that if individuals of Britain had a better understanding of the nature and disposition of New Englanders, they might not be as friendly towards them as they presently are. This might possibly recommend that there are cultural distinctions or misconceptions between the two areas that might affect their relationship. It is unclear what specific qualities or characteristics Smith is referring to, but it is clear that he thought they might have an influence on the understanding of New Englanders in Britain.
