The Children’s Encyclopaedia was published between 1908 and 1964. It was an ambitious and popular learning resource devised by Arthur Mee. It covered a broad spectrum of topics that sparked interest in – and inspired – many youngsters during its long lifespan. This sundial involved some awareness of compass principles and of the passage of time in a readily understandable form. The material benefit for the young readers was a direct involvement with topics that an iPhone can help with without the underlying principles being known let alone understood. Some young enthusiast must have added compass points in the image below.
