To John M. Clayton 
Dear Sir: May 13. 1849
Permit me to introduce to your acquaintance my esteemed friend Charles H. Constable, Esq. Mr. Constable is a Marylander by birth, who came to our state ten years ago, has fought the whig battles faithfully with us ever since, and is now a favorite with us all. He thinks of being an applicant for Charge d' Affaires to one of the South American States  and should he succeed, I, and I believe the other whigs of the state, will be much gratified. Your Obt. Servt.
