A field geologist's collection of notebook essays offering practical instruction and descriptive accounts of Carboniferous rocks. The author combines on-site observations from quarries, ravines, and rail cuttings with clear guidance on tools and techniques — hammer use, note-taking, pocket-lens study, clinometer and compass methods, mapping dips and strikes, and identifying common rocks and fossils. Emphasis is placed on tracing strata across the landscape, learning by direct observation rather than text alone, and using simple surveying practices to build a reliable local geological picture.
