In 1852, a tornado swept through Posey County, Indiana, leaving "a desolated track of one mile in breadth, on which trees, and among them the monarchs of the forest, were laid low at the rate of 7,000 a minute." These words are from John's account, as is his drawing shown here, one of the few of his surviving works of art. See
