There is in Missouri a lake, perched on the top of a mountain, its
surface from 50 to 100 feet below the level of the earth surrounding
it, fed by no surface streams, untouched by the wind, dead as the
sea of Sodom. There is no point of equal altitude from which water
could flow within hundreds of miles, and yet it has a periodical rise
of 30 feet or over, which is in no way affected by the atmospheric
conditions in the country adjacent. It may rain for weeks in Webster
County, and the return of fair weather will find Devil’s Lake at its
lowest point, while it may reach its highest point during a protracted
drouth.--_St. Louis Globe-Democrat._
