"It
is therefore recommended... to set apart Thursday the eighteenth
day of December next, for solemn thanksgiving and praise,
that with one heart and one voice the good people may express
the grateful feelings of their hearts and consecrate themselves
to the service of their divine benefactor..."
SAMUEL
ADAMS,
Father of the American Revolution, November 1,1777 (adopted
by the 13 states as the first official Thanksgiving Proclamation)
