First Biennial Report On The Geology Of Alabama PDF Download

Excerpt from First Biennial Report on the Geology of Alabama Geological Map. - Of the map accompanying the report, I can only say, that although as accurate as the materials col lected, and the extent of my observations would allow, yet it is by no means offered as a complete geological map of the State, for that would imply that the study of the geology itself was completed. It presents at a glance, a general view of the ge ological structure of Alabama, shows the relative position and extent of the great groups of rocks, laid down, it is true, with some approach to correctness, but it claims no more. To con struct a geological map with absolute accuracy, is a werk in volving much time, and is rarely attempted excepting in cases where a corps of assistants can be employed. Such are the maps of the Ordnance Survey of Great Britain, where every formation is accurately laid down from actual measurement, and sections constructed with similar care.
