However the angel ( ghost!) that discovered the plates to him, likewise informed him that he would be inspired to translate the inscriptions without looking at the plates, while an amanuensis would record his infallible reading; all which was accordingly done. But now the book must be published, the translation of the inscriptions which Smith was authorized to show to no man save a few accomplices, who subscribe a certificate of these pretended facts at the end of the volume. Truly a wise arrangement!
