This is a half-reel film telling its audience how to use inedible parts of plants from their garden to make compost. It seems pretty basic stuff, but there were a lot of city boys working in what were called Victory Gardens in the United States. Letting them know how easy it was to make compost for a better truck garden meant a lot of fresh food on the home front.One small error, or perhaps difference between British and American English: the narrator refers to the product of compost heaps as "manure". In the US, manure is what comes out of the rear ends of livestock. What comes out of compost heaps is compost.
