They turned faster and faster. The wooden gears inside, designed for the slow grind of corn and then the dry pulverisation of snuff tobacco, span beyond what they were built to handle. Friction did what friction does. The mill caught fire from the inside. By the time the flames burned out, the machinery was gone and the stone tower was a hollow shell.

Photo credit Unknown author, Public domain. Not content with a telescope and a camera obscura, West kept digging. From the observatory he drove a 200-foot tunnel through the limestone cliff, downward and outward, until it broke through into a natural cavity called St Vincent's Cave, also known as Ghyston's Cave or Giants' ...
