What is the diction tone and syntax in Washingtons Farewell Address?

As George Washington's "Farewell Address" was in actual fact a letter which he addressed to the people of America, the qualities of its diction (taken as enunciation) are not subject to analysis. In respect to Word-choice and syntax, however, the Address is an exemplar of plain, if also intelligent, English (which of course is sophisticated and complex by most contemporary standards). Its tone is dignified yet affectionate, both as a result of Washington's choice to submit his thoughts in letter-form and through his desire to offer "fatherly" advice to his fellow citizens.
