To Simon Cameron 
My dear Sir April 16. 1861
Some time ago I requested that Ben. Hardin Helm, might be appointed a Pay-Master, which I still desire. 
Next to this, for the sake of my friend, Major Hunter, I especially wish Robert A. Kinzie  to be appointed a Pay-Master. This is not a formality, but an earnest reality. Your Obt. Servt.
