1From James Madison to Albert Gallatin, 13 September 1815 (Madison Papers)
In my hurry yesterday to be ready for a waiting mail, I overlooked your question when I should return to Washington? I have not fixed on the precise time, but it will probably be not sooner nor more than a few days later than the 1st. of October. If you have a trip there in view why not extend it, bringing Mrs Gallatin with you, to Virginia? Cordial regards RC ( NHi : Gallatin Papers).
