Comment of the Prophtet on the Kinderhook Plates.
I insert fac-similes of the six brass plates found near Kinderhook, in Pike county, Illinois, on April 23, by Mr. Robert Wiley and others, while excavating a large mound. They found a skeleton about six feet from the surface of the earth, which must have stood nine feet high. The plates were found on the breast of the skeleton and were covered on both sides with ancient characters.
I have translated a portion of them, and find they contain the history of the person with whom they were found. He was a descendant of Ham, through the loins of Pharaoh, king of Egypt, and that he received his kingdom from the Ruler of heaven and earth.
