The State Geologist is hereby empowered and directed to cooperate with the United States Geological Survey in the execution of the topographic surveys of the State of Alabama in a manner sufficiently elaborate to prepare maps on scales which may be agreed upon for different localities exhibiting the land and water features, relief, roads, buildings and all civil boundary lines as marked on the ground at the time field surveys are executed and to establish permanent bench marks along highways and other routes of travel marked with elevations based on mean sea level.
