A remarkably detailed and colorful map depicting, through legend and color, twenty different geological formations, plus fine detail of roads, post offices, cities, village, roads, etc. The map is important because it was the first geological map prepared for the state. It is also an excellent economic map with a detailed legend at bottom that identifies churches, mills or manufactory, furnace, forges, glass works, taverns, dwelling houses, etc. Lithographed by Duval in Philadelphia. A geological survey of New Jersey was conducted 1835-1839 under the leadership of Rogers, Professor of Geology at the University of Pennsylvania and the leading geologist of his time. This remarkable map rarely comes to market, and it is very uncommon to find it complete with the original report, Description of the Geology of the State of New Jersey being a Final Report, 1840 by H.D. Rogers, printed by C. Sherman & Co., Philadelphia. The fold-out frontis shows three sections. New Jersey was one of the first states to complete and publish results of its survey in final form. Rogers later became State Geologist for Pennsylvania. His career culminated with the publication of his landmark geological report for that state in 1858. Octavo, 301pp. Hardbound in embossed brown cloth leather label on spine with title in gilt. Bookplate of the University of London inside front cover; accompanied by a deaccession letter.
