The above letter I have obtained in answer to several questions respecting Mormons and Mormonism, transmitted by the Rev. Mr. Quinan to Dr. A. Hawley, of _this county_, from you. This letter of Dr. Rosa's, together with the book, "Mormonism Unveiled" which accompanies it, I send as the best answers to your questions, and the best expositions of Mormonism which can be obtained. It is believed by candid and respectable people in the vicinity of the Mormon Temple, that Mr. Howe's book--"Mormonism Unveiled"--is very correct. As to the deponents in reference to Spalding manuscript, at New Salem (now Conneaut), I have been acquainted with them for thirty years (excepting Miller), and believe them to be credible and respectable persons. It is indeed astonishing that so low an imposture should ever have been countenanced at all; much more so that hundreds of English converts should recently have come over to it, and that four hundred more should now be daily expected to take shipping at Buffalo, in order to pass up our Lakes to join the Western Mormons! JOHN HALL, _Rector of St. Peter's, Ashtabula, Ohio_. In the conclusion of Mr. Howe's book--referred to in the preceding letter--we were particularly struck with the following statement, which seems to account perfectly for Rigdon's easy faith, and to identify him with this scheme of imposture from its very origin. The reader will recollect that Mrs. Davison states that the manuscript was lent to Mr. Patterson, the publisher of a newspaper in Pittsburg, with whose office Rigdon was connected. The author of the volume above referred to, says:--"It was inferred at once that some light might be shed upon this subject, and the mystery revealed, by applying to Patterson & Lambdin, in Pittsburg. But here again death had interposed a barrier. That establishment was dissolved and broken up many years since, and Lambdin died about eight years ago. Mr. Patterson says he has no recollection of any such manuscript being brought there for publication, neither would he have been likely to have seen it, as the business of printing was conducted wholly by Lambdin at that time. He says, however, that many manuscript books and pamphlets were brought to the office about that time, which remained upon their shelves for years, without being printed or even examined. Now, there is the strongest presumption that Spalding's manuscript, (or a copy of it) remained there in seclusion, till about the year 1823 or '24, at which time _Sidney Rigdon_ located himself in that city. We have been credibly informed that he was on terms of intimacy with Lambdin, being seen frequently in his shop. Rigdon resided in Pittsburg about three years, and during the whole of that time, as he has since frequently asserted, abandoned preaching and all other employment, for the
