Letter from office of Johnston Brothers & Co., bankers, Baltimore, August 1865. "Dear sir: Please advise distinctly, by return mail, what you will pay in greenbacks or coin for your circulation, when presented in sums of one thousand dollars or upwards? Be good enough also to advise if there is likely to be an improvement or otherwise in your rates. We hold a large amount of these notes, costing us high figures, and will be thankful for any information you may give us with regard to them." Addressed by hand to W.B. Campbell, cashier, Lebanon, Tenn.
