Steam power and Little Toot on the Mississippi

We are studying steam with respect to Mike Mulligan and his steam shovel and so we read this cute little book to go along with it. Its about a little steamboat that goes down the Mississippi looking for magnificent steamships just to find them parked in a bayou and they recalled how they used to be great and how they would pull up and pick up or let off people from Mansions.  But now we are useless. But the flood of the Mississippi strands a lot of animals and against the tremendous force of the Mississippi, the steamboats make there way and save the animals. After this, they retire again to the Bayou.
