  • Standards for the classifiion of public coal lands

     · In order to provide uniformity in the classifiion of coal lands in the public domain, certain standards have been prepared from time to time by the Geological Survey. The controlling factors are the depth, quality, and thickness of the coal beds. The first regulations were issued April 8, 1907; others followed in 1908, 1909, and 1913.
