I—Where are the plates now?
He—In a cave, where the angel has hidden them up till the time arrives when the plates, which are sealed, shall be translated. God will yet raise up in a mighty one, who shall do his work till it is finished and Jesus comes again.
I—Where is that cave?
He—In the State of New York.
I—In the Hill of Comorah?
He—No, but not far away from that place.
