Some time ago, a petition, signed by the principal inhabitants of this city, praying the postmaster-general to remove the present Nauvoo postmaster and appoint another in his stead, was put in the hands of C. A. Warren, Esq., of Quincy, with a request that he would hand it to you about the time you left for Washington. We have not yet heard whether Mr. Warren handed it to you or neglected to do so, but we feel extremely anxious to learn something on the subject, as the citizens generally are suffering severely from the impositions and dishonest {267} conduct of the postmaster and those connected with the postoffice in this city. The petition was accompanied by some affidavits, proving that letters had frequently been broken open, money detained, and letters charged twice over, &c, &c., at this office, the repeated occurrence of which circumstances caused the people to be anxious for an immediate change. It will be seen by the petition, that I was nominated for the office. I can only say that, if I receive the appointment, I shall do my utmost to give general satisfaction. Whoever may be appointed, it is necessary, in my estimation, to have it done as soon as circumstances will possibly admit. Accept, sir, of my sincere acknowledgments for past favors, which are not forgotten, and accept of the best wishes and sincere thanks of yours respectfully, JOSEPH SMITH.

[A] [Footnote A: See Doctrine and Covenants, sec. cxxix.] _Three Grand Keys by which Good or Bad Angels or Spirits may be Known--Revealed to Joseph the Prophet, at Nauvoo, Illinois, February 9, 1843_. There are two kinds of beings in heaven--viz., angels, who are resurrected personages, having bodies of flesh and bones. For instance, Jesus said, "Handle me and see, for a spirit hath not flesh and bones, as ye see me have." 2nd. The spirits of just men made perfect--they who are not resurrected, but inherit the same glory. When a messenger comes, saying he has a message from God, offer him your hand, and request him to shake hands with you. If he be an angel he will do so, and you will feel his hand. If he be the spirit of a just man made perfect, he will come in his glory; for that is the only way he can appear. Ask him to shake hands with you, but he will not move, because it is contrary to the order of heaven for a just man to deceive; but he will still deliver his message. If it be the devil as an angel of light, when you ask him to shake hands he will offer you his hand, and you will not feel anything; you may therefore detect him. These are three grand keys whereby you may know whether any administration is from God. [Sidenote: Items of the Prophet's Experience.]
