Ms. Manthey happyly reported the results of the quiz to the class. On question number two they were alright. Every student had correctly picked Osceola as the town that had once been on the banks of the Mississippi. On question number five, however, there was disagreement between the students. They discussed the answer for awhile. Less than five students knew that the Mississippi carried sediment at a rate of 30 tons per second. A larger amount of them thought that it was less. On the essay question, one student, Quanah, described the river as plaiful because it meanders back and forth below the confluence of the Ohio River.
