The third state of this rare and important map of Ohio and Indiana by H.S. Tanner and published in his "New American Atlas".
The rare first edition with "Miami Indians" and "Indian Reservation" in the Northwest part of Indiana while dates May 24, 1819, its inclusion of Randolph County, Indiana suggests that it was completed in or after August 1818, when Randolph County was first created, but before January 1, 1819, when Owen County was created from the Northern Part of Sullivan County, Indiana.
Many Indian settlements are shown in the north. While the county system in Ohio is more complete, there are still many signs of earlier days, including notes of British & American Forts and Indian Villages. Extensive notes on roads, rivers and many other features. An essential map for Midwest collectors.
The third state adds a number of new counties, including Randolph County, the first to extend as far north as the Maumee River. There are two northern boundaries of Indiana shown. A note indicates that boats may pass from Lake Michigan to the Au Plain River at high tide, near Ft. Dearborn, which is connected to Ft. Wayne by a road.

Henry Schenck Tanner (1786-1858) was born in New York City but removed early to Philadelphia. Trained as an engraver, he engraved many of his maps in the 1804 edition of A New and Elegant General Atlas of Arrowsmith and Lewis. He engraved the frontispiece and many of the maps in John Melish's Military and Topographical Atlas of the United States (1813 and 1815). and with J.Vallance, engraved Melish's fundamental "Map of the United States" (1816), the text accompanying which shaped Tanner's thought. In 1818-1823 he published A New American Atlas, in parts, which went to many editions.

Contemporary reviews of the atlas were favourable: the New American Atlas "is decidedly one of the most splendid works of the kind ever executed in this country" (United States Gazette, September 1823). Never "has either America or Europe, produced a geographical description of the several States of the Union, so honorable to the Arts, and so creditable to the nation as Tanner's American Atlas." (National Advocate 25 August 1824). Perhaps the most enthusiastic report came from the scholar Jared Sparks who wrote in the April 1824 issue of the North American Review that "as an American Atlas, we believe Mr. Tanner's work to hold a rank far above any other, which has been published."
