In an attempt to limit inflation the Treasury Department's plan in 1864 was to reduce circulating paper money by forced funding of the Treasury notes into bonds or to exchange new money at a rate of two new for three dollars of the old currency. Most prefered currency to bonds.
It is possible the deposit by Reverend Folsom at the Depository in Marshall,Texas may have been an earlier portion of a Confederate anuity payment to the Choctaw or perhaps even the balance of their Treasury. I do not know. There was never a CS Depository located in The Indian Territory. Certainly tho it would have been a very dangerous trip to Texas with such a large amount of money and great trust in the man shown by his fellow Choctaws and other Friendly Indians. We must assume he made it back safe to the Territory with the $44,810 in new issue CSA Treasury notes.
