The July 14 Baltimore SUN includes a Twain headline just below the fold on the front page: "Twain's hometown braces for river crest." Several paragraphs in, the story contains the following information: That $8 million levell, completed just this spring, was built to withstand a flood beyond anything this town ever expected -- a 32.5-foot crest. And that -- a 32- foot crest -- is just what was expected last night or this morning. Downtown Hannibal -- the childhood home of Mark Twain and the setting for the escapes of Tom Sawyer and Huck Finn -- lies on a slpe near the river. The new levee now blocks the view of the Mississippi from the picket-fenced (yes, its whitewashed) house which Samuel Clemens grew up in and which is now a part of a Mark Twain museum. Even Hannibal citizens are surprised to learn that in Twain's lifetime there were no severe floods here. "With the levee and flood protection projects of the 1920s and '30s, the river was forced into a narrower channel and [flooding is] going to get deeper. The water used to be allowed to spread out across bottom lowlands," explains Henry Sweets, director of the Mark Twain Home and Museum. ...... "Mark Twain had seen earlier attempts to control the river. He thought [it] could overcome any obstacle man could put in front of it," said Mr. Sweets. "He may be right, the river goes where it wants to and it's pretty hard to say no." I suspect that materials at the home an museum have been moved above the ground level though the article does not talk about that issue at all. Good luck to the museum and to the thousands who must endure the rage of the river. David Tomlinson
