"In full color. The explanation of the color is not given on the map. The title page is dated 1817 and the text is unchanged from the 1817 edition, but the Melish base map is changed from the 1817 edition Melish map to one that shows all of Florida and Missouri and Arkansas (with Arkansas in an 1828 formation). The map is the second state (White 1817B), although it is really an entirely different map. It is similar to the Map of The United States that appears in Melish's Traveler's Guide of 1822 and in Carey and Lea's American Atlas, but it has been reengraved, and the title is changed to United States of North America. It is colored geologically, but there is no color key. The same map appears in the Jackson Wreath of 1829, but in an earlier state. Bound in at the back is the ""Essay..."" mentioned above. This copy belonged to Francis P. Farquhar, noted California historian. Bound in brown cloth covers with ""Geology"" printed in gold on the spine."
