Mike and his trusty steam shovel, Mary Anne, dig deep canals for boats to travel through, cut mountain passes for trains and hollow out cellars for city skyscrapers. But with progress comes new machines and soon the inseparable duo are out of work. So, Mike Mulligan and Mary Anne travel to the small town of Popperville and accept one final challenge-to dig the town cellar in just one day. What happens is a testament to their friendship and to old-fashioned hard work and ingenuity. For ages 3-8. Paperback by Virginia Lee Burton. 48 pages, measures 9-1/4 x 8-1/2".
