"Representatives and direct taxes shall be apportioned among the several States, which may be included within this Confederacy, according to their respective numbers, which shall be determined by adding to the whole number of free persons, including those bound to service for a term of years, and excluding Indians not taxed, three-fifths of all slaves."
Sorry, I should have been more explicit. When I said “newly formed Confederation” I was referring to the Articles of Confederation of the United States. But it is interesting to note that they added that formula into their “constitution” after rejecting it for ours.
