Once upon a time children worked.  They worked hard and dangerous jobs from an early age.  Lewis Hine went town to town across the country taking pictures of these working children to make the populace understand, that factories and mills were no place for children.  They belonged in the parks and the playground. This book is based on true works, and many new laws were passed to keep children safe.  But now a century later, our modem government are loosening the child labor laws.  Hine would roll over in is grave and be back on the train with his camera if he knew.
