In the first place, then, it must be remembered how great the task would be to become sufficiently acquainted with American antiquities and traditions to make the Book of Mormon story and the alleged customs of its people agree with the antiquities and traditions of the American natives, in the striking manner in which we have found them to agree. In the second place the youthfulness of the Prophet must be taken into account--he was but twenty-five years of age when the Book of Mormon was published, and it is the concensus of opinion on the part of all those competent to speak upon the subject, that he was not a student of books. But what is most important of all, and what settles the question on this point (whether Joseph Smith, Solomon Spaulding, or Sidney Rigdon be regarded as the author) is the fact that the means through which to obtain the necessary knowledge of American antiquities, the body of literature in English now at one's command on the subject, was not then (1823-1830) in existence. The Spanish and native American writers previous to 1830 may be dismissed from consideration at once, since their works could not be available to Joseph Smith and his associates because written in a language unknown to them, and such fragmentary translations of them as existed were so rare as to be inaccessible to men of western New York and Ohio. About the only works to which Joseph Smith could possibly have had access before the publication of the Book of Mormon would have been: First, the publications of the "American Antiquarian Society, Translations and Collections," published in the "Archaeoligia Americana," Worcester, Massachusetts, 1820; but this information was so fragmentary in character that it could not possibly have supplied the historical incidents of the Book of Mormon, or the customs of its peoples, even could it be proven that Joseph Smith had been familiar with that collection. Second, the little work of Ethan Smith, published in Vermont--second edition 1825--in which the author holds the native American Indian tribes to be descendants of the ten lost tribes of Israel. In fact his work bears the title, "View of the Hebrews; or the Tribes of Israel in America." Third, "The History of the American Indians," by James Adair, published in England, 1775. Mr. Adair confines the scope of his work to the North American Indians. Fourth. The translation of some parts of Humboldt's works on New Spain, published first in America and England between the years 1806 and 1809, and later Black's enlarged translation of them in New York, 1811.
