Mike Mulligan and his Steam Shovel
Mike Mulligan and his steam shovel, Mary Anne, do various digging jobs. The more people watching them, the faster and better they work. Then newer shovels that are not steam powered are invented and no one wants to hire steam shovels anymore. One day, Mike Mulligan sees in the newspaper that the town of Popperville is building a new town hall and Mike Mulligan decides that he will dig the cellar for the new town hall.
This is a great book for young children who like machines and it also tells a very good story.
