The map of New England from Henry S. Tanner’s monumental New American Atlas. The atlas was first issued in parts between 1819 and 1823, while the present map is from the 1825 revised edition.

Tanner’s life and work-and the American Atlas in particular-merit an entire chapter in Ristow’s American Maps and Mapmakers (chap. 13). Among other things, Ristow quotes and extremely positive review of Tanner’s atlas by the scholar Jared Sparks:

“…on the whole as an American Atlas, we believe Mr. Tanner’s work to hold a rank far above any other, which has been published. The authentic documents, to which he had access, the abundance of his materials, the apparent fidelity, with which they are compiled, the accurate construction of his maps, and the elegance with which they are executed, all these afford ample proofs of the high character of the work, of its usefulness as a means of extending the geographic knowledge of our own country, and of its claims to public patronage.” (Ristow, p. 197)
