The Mississippi
The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century. The River Indians used it as a highway and as a source of food, and it was they who gave it its name—“misi” meaning “great” and “sipi” meaning “water”．When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater. 71 . From the source of the Missouri to the tip of the delta (三角洲), it is 2, 480 miles long.
Great rivers are likely to suffer floods. In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path. In 1938 its floods drowned or killed 200 people and made millions homeless. Today the river has largely been controlled.
