Elder Kimball showed the right fashion for a leaf, spoke of Elder Richards being protected at Carthage Jail, having on the robe, while Joseph and Hyrum and Elder Taylor were shot to pieces, said the Twelve would have to leave shortly, for a charge of treason would be brought against them for swearing us to avenge the blood of the anointed ones, and some one would reveal it and we shall have to part some say between sundown and dark.

George Miller said that when near the camp of Gen[eral] Hardin, he was shot at, and the Sentinel who was near him was killed, but he escaped unhurt, having on his garment. He then spoke of the design and purpose for which all the Symbols in the garden were given &c. Paul said he bore in his body the marks of the Lord Jesus Christ, which was as plainly as he dare allude to these things in writing. But the marks Paul alluded to were just such as we now have on our garments. He spoke of the signs, tokens and penalties and of the work in general, said it was the work of God, by which he designs to reinstitute man into his presence &c.
