Steam shovel

A steam shovel is a big machine that digs things up using steam power. It has a big long arm that ends in a scoop that can scoop up dirt, rocks, and other things on the ground. The machine is powered by steam, which is like hot air, and it makes the machine move and do its job. It's kind of like having a really big robot helper that can dig up huge amounts of dirt and rocks in a short amount of time - like when you are playing with a toy digger in the sand, but way bigger and cooler!
