In part: “I have had a conversation with Commodore Crane relative to your eye piece. The authority given to him and through him to me in the case, is based upon your propositions to the Secretary of the Navy. The date of the letter I do not now recollect but, it was the letter with which you enclosed one from Bache. The Commodore suggests and I can concur with him, that you had better have the exclusive contract of the mechanical execution of your contrivance…and then I will take it up and pronounce upon its practical operation.” In fine condition.
