At Christmas 1936, Presbyterian children in New Zealand raised over £400 for an x-ray machine in a south Chinese missionary hospital. From the early 1800s, thousands of children in the British world had engaged in similar activities, raising significant amounts of money to support missionary projects world-wide. But was money the most important thing? Hugh Morrison argues that children's education was a more important motive and outcome. This is the first book-length attempt to bring together evidence from across a range of British contexts. In particular it focuses on children's literature, the impact of imperialism and nationalism, and the role of emotions.
