Mark Twain,
Roughing It — Chapter LVIII
(1872)
“ The plastering that fell from ceilings in San Francisco that day, would have covered several acres of ground. For some days afterward, groups of eyeing and pointing men stood about many a building, looking at long zig-zag cracks that extended from the eaves to the ground. Four feet of the tops of three chimneys on one house were broken square off and turned around in such a way as to completely stop the draft.A crack a hundred feet long gaped open six inches wide in the middle of one street and then shut together again with such force, as to ridge up the meeting earth like a slender grave. ”
