The Smith's were coopers---they made barrels, buckets, tubs, pots, etc.  At one time the Gold Plates were hidden under the floor of the Cooper Shop.  Joseph had a strong impression that he should move the Plates.  He took up the floor, removed the Plates from the box they were stored in..(they think it was the box the windows for the Frame Home were shipped in), wrapped them in some cloth and hid them in the rafters where some flax was stored.  That night the mob came, tore up the floor, smashed the box to pieces and basically tore up the place.  Little did they know that the Plates were two feet above their heads....they never bothered to look up.
