Historians have taken it for granted that the Revolutionary, debt was fairly well concentrated before it was funded in 1790, but they have not been able to support this view with concrete evidence. Most of the people living at the time thought the same thing but were likewise unable to prove it. The truth could not be known until Hamilton's funding operation assembled the securities that made up the debt. Under the act of 1790 a new federal loan was instituted. Various kinds of securities representing unpaid claims against the government were taken as subscriptions and the possessors given new federal stock. As nearly all the old securities came in, the government had full information about the transfer and ownership of the Revolutionary debt. The details, however, were not made public. Later, a succession of fires in the treasury destroyed nearly all the central records. Documents now existing, though voluminous, are scattered, incomplete, and hard to interpret. Historians have not made much use of them. For this reason, the ownership of the debt, which was a question in 1790, is a question still.
