You assume that everyone in Spalding's day would have believed if they believed in the lost tribe myth ..that all 10 tribes migrated to the Americas en masse. If that is what the conneaut witnesses believed and Spalding must have believed...they why would they say in the same statement...the book showed Am. Ind. are descendants of lost tribes..and he brought them from Jerusalem under the command of Nephi and Lehi?
You know what Glenn..perhaps you could summarize your argument as succinctly as you can..and then I'll see if I'm missing something. Keep in mind I am not arguing against a Bering str..migration..if that's what you think.
Ok I've cont'd looking into this and did a search and came across Dan Vogel's book http://www.signaturebookslibrary.org/indian/indian3.htm#Book
so let me quote:
"Early writers experimented with several possible Jewish migrations: a flight from Sennacherib about 700 B.C.; navigation during the time of Solomon; or a flight from the Romans at the destruction of Jerusalem around A.D. 70.29 But the theory which received perhaps the greatest support and captured the popular imagination in Joseph Smith's day was that which asserted that the Indians were the lost ten tribes of Israel. The theory is based on the apocryphal book 2 Esdras (written about A.D. 100), and included in some nineteenth-century editions of the Bible, [40] which mentions the Assyrian captivity of the northern kingdom of Israel around 734 B.C. An angel shows Ezra a vision of a crowd of people, explaining:..."

The debate over Indian origins did not end with a solution to whether the Indians were Adamic or pre-Adamic or whether they had come from Babel or Israel. Those who postulated an Old World origin for the Indians, whatever the theory, had to solve other more specific problems. For example, how and over what route had the Indians traveled to America? Where did they first settle? And what plants and animals were found in the New World? Again, there was no shortage of those willing to speculate about the blanks in New World history.
The mode of travel became the focus of considerable debate. When the dimensions of the New World were finally mapped and it was discovered that the Bering Strait was the point at which the Old and New Worlds were closest, many early writers speculated that it was the place where the first settlers crossed. The Congregational clergyman Jedidiah Morse came close to articulating twentieth-century views when he suggested that the two continents were at one time actually connected by a small "neck of land" which had since been submerged under the [45] ocean.54 Ethan Smith's theory that the Ten Tribes may have crossed the Bering Strait on ice is also interesting.55 Still other writers postulated that America's ancient inhabitants crossed the Bering Strait in small canoes. These suggestions, however, were criticized by James McCulloh, curator of the Maryland Academy of Science, who dismissed them as wishful thinking.56 McCulloh himself proposed that the continent of Atlantis was anciently situated in the Atlantic Ocean and therefore provided a land bridge for people and animals to cross.
A number of critics of the Bering Strait theory pointed out that it would have been impossible for tropical animals to migrate through the arctic zone57 and instead proposed some kind of transoceanic crossing. In a book published in 1761, Journal of a Voyage to North-America, Frenchman Pierre de Charlevoix strongly argued against the pre-Adamite theory, contending that the ancients could have sailed to America from the tower of Babel in a ship like Noah's since they would surely have retained the knowledge of ship building from him.58 "Who can seriously believe," wrote Charlevoix, "that Noah … the builder and pilot of the greatest ship that ever was … should not have communicated to those of his descendants who survived him, and by whose means he was to execute the order of the great Creator, to people the universe, I say, who can believe he should not have communicated to them the art of sailing upon an ocean."59
The Palmyra Herald suggested in 1823 that some Asiatics could have crossed the Pacific Ocean in ancient times and afterwards that some Europeans could have crossed the Atlantic Ocean.60 Debates about such ocean crossings often turned on questions about navigation. Many argued against migration by sea since the ancients had no knowledge of the mariner's compass.61 These arguments caused some writers to delay the arrival of the first Americans until Phoenician navigators could make the trip.62 But the idea that the first settlers of America came by sea was criticized by McCulloh. Even if ancient navigators had reached the New World, he questioned, why would they have brought vicious and useless animals like the wolf and the poisonous snake with them?63 But for the believer, one might as well ask why Noah had preserved wild and vicious animals. There could be only one answer: Noah followed God's will. That might have also been true for America's first settlers."
So not everyone in Spalding and Smith's day..thought that via the Bering str by foot was the only way ancestor of Am. Ind migrated.
The Conneaut witnesses talked about Spalding's story being a migration via land and sea. And there is no way all 10 lost tribes in millions or whatever large numbers they were alleged to be could have jn theory or by any stretch of one's imagination been theorized to migrate to the Americas by boat..only in theory a portion could. Hence Spalding may have had an explanation for what happened to the lost tribes right after 723 B.C. , but that by the time Lehi and Nephi migrate later on, they as the principal characters are used along with whomever they are migrating with to be representatives of the lost tribes in order that the story will be about Am Indians being their ultimate descendants.
There is no way Glenn that all 8 witnesses are confused and mixing up Manuscript Story Conneaut Creek...with something they may have heard or read such as Ethan Smith's mass migration theory over the Bering Str. There is nothing at all about lost tribes in MSCC. (by the way..I am assuming based on what you've said that Ethan Smith's theory involves a mass migration of all 10 tribes..whatever their alleged numbers)
And you may ask why didn't the Conneaut witnesses get into more details...well there would be little purpose to that. Spalding's manuscript wasn't around to verify their recollection. So why should they bother with all sorts of details. A general brief concise outline of what they recalled with a few details is all that was necessary. The point of the exercise for them was simply whether or not they identified Spalding's writings in the Book of Mormon.
