Dan Vogel: [Philastus Hurlbut] got a hold of this manuscript eventually but never published it because it wasn't anything like the Book of Mormon. And his affidavits were much more powerful without publishing the manuscript. And so when the manuscript didn't match... Hurlburt is sincere about finding it didn't match. So they start trying to reconcile the memories of his neighbors and family and they invent an explanation to reconcile those two that conflicting information which was there must be another manuscript. And then people start saying, "Oh yeah there must be another manuscript if my memory says it was about the ten tribes." And that how it kind of started. When you look at the testimony of the families and friends the earliest testimony is based on their reading of the Book of Mormon. They didn't interview them before they read the Book of Mormon saying, "What do you remember about this manuscript?" They have vague memories of this manuscript being read to them by Spalding and some of them read it themselves, I guess. These vague memories start being triggered by their reading of the Book of Mormon which taints those memories and they start constructing new memories... These vague memories with the Spalding witnesses in the very beginning are implanted and reshaped and they think they actually remember. And when you look at their testimonies really carefully line for line you'll find that there is a lot of discrepancies, you know, and a lot of problems with this testimony is relied on. And other people start remembering things and mostly the research throughout the 19th century on the Spalding thing is done by religiously motivated researchers who some of them I believe out-and-out lied and they provided evidence that was missing. And I think it's gotten terribly out of hand on the Internet, actually, so I don't believe there's anything like that it happened. And what another problem is trying to say that how did the manuscript get to Joseph Smith? And they tried to do it through Sidney Rigdon and what happens is Sidney Rigdon over here in Ohio and Joseph Smith over here in New York how does the manuscript get to Ohio or to New York from Ohio to New York?... And think that "Oh he had to like take [the Book of Mormon] to Joseph Smith instead of revealing it himself." And how did he know about Joseph Smith? There no connection, and so what happens is very fortuitous. That Parley P. Pratt leaves Ohio and goes to New York and accidentally hears about the Book of Mormon as he's traveling western New York on a preaching tour... For this all to work you have to have a conspiracy, massive conspiracy not only does Sidney Rigdon have to be in the conspiracy but Pratt has to be in the conspiracy. And the conspiracy widens that you keep on going with trying to explain how all these things take place, so anyway I do not support the Spaulding theory as Joseph Smith's source.
