Dear Sir,―It was proposed to me at New York to drop the Indian name of Ischue or Ischua (it is also spelt other ways). Confusion might arise from the various spellings, of which to obviate all risk I have concluded so to do as proposed. The neighborhood of the oil spring suggests a name different in sound, though perhaps not different in meaning, which I wish to adopt,―it is "Olean." You will do me a favor by assisting me to establish this name. It may easily be done now by your concurrence. The purpose will be most effectually answered by employing the term, when occasion requires, without saying anything of an intended change of name. To begin, you will greatly oblige me by addressing the first letter you may have occasion to write to me, after I receive the survey, to the Mouth of Olean. The bearer being properly instructed, there will be thereafter no difficulty. Your co-operation in the matter (the effect of which, though not important in itself, may be so on account of precision) will oblige. Your servant, A. HOOPS
