said it best:
"In the space of one hundred and seventy-six years the Mississippi has shortened itself two
hundred and forty-two miles. Therefore ... in the Old Silurian Period the Mississippi River was upward of one million three
hundred thousand miles long ... seven hundred and forty-two years from now the Mississippi will be only a mile and three-quarters
long. ... There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling
investment of fact."
