The Third and Last Principal Business Book Called the Ledger. How It Is to be Kept Double With Its Index, or Single Without.

After all the transactions in the Journal have been entered in an orderly manner, you must post them to the third book called the Ledger. The Ledger usually contains twice as many pages as the Journal. It should contain an Alphabet or Repertory, or as some call it, an Index (the Florentines call it Stratto). Enter in the Index all debits and credits in alphabetical order, together with the numbers of their respective pages: Those names that begin with the letter A, on the page marked A, and so on. It will be best to assign the marks to the pages of the Ledger that correspond to those that appear on the Journal and Memorandum.
