The cannon's yeoman's tale is a story told by a yeoman, about his experience working under his cannon. His cannon is a failed alchemist that spends vast amounts of money on experiments that all ultimately fail. Any time one of the experiments fail he buys all new lab equipment, instead of trying to save and reuse salvageable equipment. He is not a smart man with money, he spends tons in hopes of making a breakthrough. They take their money form "investors" and then run away when they can not pay it back. The second tale in this tory is also about another yeoman who is also a failed alchemist. He takes peoples gold, and money and tells them he can make it into more gold out of it, but he never succeeds. This alchemist also deceives a priest by convincing him he can convert cheap things into valuable metals.
