I met with the Twelve at Brother Joseph's. He conversed with us in a familiar manner on a variety of subjects, and explained to us the Urim and Thummim which he found with the plates, called in the Book of Mormon the Interpreters. He said that every man who lived on the earth was entitled to a seerstone, and should have one, but they are kept from them in consequence of their wickedness, and most of those who do find one make an evil use of it; he showed us his seerstone.
