SIR,--Two letters were put into my hands this morning relative to the witnesses of Mr. Avery's innocence as to being accessory to horse stealing some four years since. In the first place, Mr. Avery was abducted from this State without process, contrary to law. In the second place, the principal for felony by the law of Missouri should be indicted within three years, &c. Again, the revised statutes of Missouri have a wise provision in such cases as Mr. Avery's. If Mr. Avery, therefore, will sue out a commission according to the law concerning {133} depositions, (R. S., page 219 to 222,) directed to Alderman Geo. W. Harris, an acting justice of the peace for the city of Nauvoo, and county of Hancock, the necessary testimony to establish Mr. Avery's innocence will be taken according to law, and forwarded to the proper officer in due time. Respectfully, &c.. W. W. PHELPS. J. WHITE, ESQ., Dep. Sheriff, Clark Co., Waterloo, Mo. P.S. You will have the politeness to show this to Mr. Avery. In the evening I was visited by several strangers, and had considerable conversation with them. _Friday, 22.--_At home at nine o'clock, a.m., reading a magazine to my children. [Sidenote: Attitude of Prophet on Mobocracy and Politics.] A little after twelve went into the store-room occupied by Butler and Lewis, and commenced a conversation with Dr. John F. Charles, to convince him that mobocracy is not justifiable, and that I did not deal in politics. David Holman, living about two miles from Ramus, went out in the evening with his family visiting. About ten o'clock he discovered his house on fire. The neighbors had inquired how long he would be gone. A man rode to Carthage. A company went up, secured the provisions to themselves, and fired the house. Warm and pleasant weather. _Saturday, 23.--_At home, counseling the brethren who called on me, and attending to my domestic duties, making preparations for a Christmas dinner party. Prayer meeting in the Assembly Room. _Sunday, 24.--_At home. Received a visit from Mr. Richardson, one of the men who assisted in kidnapping Avery. He manifested some repentance and sorrow for his part in that transaction, and promised to use what influence he had with the Missourians to have Avery set at liberty.
