               Alexander Campbell, "Delusions," Millennial Harbinger, 7                                February, 1831: 83.

I had read the Book of Mormon enough to find in the terms "gunpowder, mariner's compass," and several others introduced into a silly story . . . . There are also references to pistols and other fire arms.

               Christian Watchman, 5 May, 1837.
