This map was printed by a technique of wax engraving called ""cerography"" which was developed by Sidney Morse and Henry Munson. Sidney's father Jedidiah Morse was a reverend (b. 1761-d.1832) who became a publisher, inventor and journalist in New York. He prepared a popular textbook Geography Made Easy in 1784 (until 1802) which earned him the title ""father of American Geography"".
Samuel Breese was a map compiler who worked with S.E. Morse and compiled the maps for Morse's North American Atlas of 1842.
The geographical features of the map are fairly accurate for the time but the major eastern portion of the peninsula has a huge area labeled ""Leigh Read"" in the area sometimes called Mosquito County (until 1845). There never was an official county named Leigh Read. However, the legislature tried to change the name of Mosquito County to Leigh Read in 1842 to honor him for being a member of the Florida Legislative Council, Speaker of the House of Representatives and Brigadier General under President Jackson. In 1839 he was a signer of a constitution that prevented pistol duels. However, he himself shot and killed an antagonist Augustus Alston in a duel. Alston's brother Willis shot and killed Read in a shotgun ambush on April 27, 1841. This map is probably the only one ever published which shows his name on a county.
