R., L. H. reports that Joseph engaged in peeping and spectacle use, which led to him doing that with the BOM.

Little enough did "Joseph Smith, jr., author and proprietor" of said book, imagine such events, and yet such have taken place! Gladly would he while engaged in "peeping," sometimes into an old hat, and at others into the spectacles, "called Urim and Thummim," through which he was enabled to read "the plates," and dictate to Oliver Cowdery, his amanuensis; gladly, no doubt, would he then have swapped his whole interest in the concern for a fifty acre farm in Michigan.
