This early folding geological map of the United States is the frontis for "An Elementary Treatise on Mineralogy and Geology, Designed for the Use of Pupils”," by Parker Cleaveland, Boston, published by Cummings & Hilliard. The map's geology is by Parker Cleaveland and was drawn by H. Morse. It extends into Texas to include San Antonio. Contains great watershed detail and uses hand coloring to suggest five or six geological formations. Marcou says this map is a reissue of the 1817 Maclure's Geological Map "with very few additions or variations." It is in the complete, original volume (5.5" x 9") in leather boards, both volumes bound together as one. Second edition, octavo, xii, 480, 481-818 pp. and errata leaf plus 6 plates including frontis map of the United States. One of the most famous and widely used mineralogical reference works of the early 19th century in America. Very scarce especially with the map present.
