B. Young discusses J. Smith's five seer stones.
Brigham Young, Historian's Office, General Church Minutes, 30 September 1855
Oliver sent me Joseph's first seer stone, Oliver always kept it until he sent it to me - the second seer stone Dr. Williams had - the third one was a very large. Joseph found two small ones on the beach in Nauvoo - a little larger than a black walnut without the shock on. Joseph Said there is a stone for every person on the earth.
