The periauger was flat-bottomed, dugout workboat in the state's waterways during the 18th- and early 19th-centuries that disappeared in the first half of the 19th-century. Improved roadways, the opening of more railroad lines, and the steamboat contributed to its demise. Archaeologists have yet to find the remains of a vessel of this type in the state. In 2004, a group of marine historians successfully planned, built, and sailed a reproduction of periauger. Wilson discusses the project.
