Alice Felt Tyler describes William Miller's failed prediction of the end of the world:
' ... Preparations for the end were made by countless hundreds of joyous or desperate souls. White cloth was purchased and made into ascension robes. Nearly all secular business was neglected ... Voting was light ... Tents were put up outside cities ... and hundreds of people assembled on the night of October 21  to keep their vigil together. No provision was made for food ... the tension was intolerable ... There were several suicides, and as the dawn of October 23 served notice that "time continued" regardless of prophecy, some heart-broken Millennialists were led away insane. '
[Joseph Smith had denounced Miller's prophecies]
