These are the Centerburg , Cygnet , Haney , Houcktown , Jugtown , Nicely , Reaville , Thackery , Tuscola , Vanlue , and Williamstown series. Centerburg and Williamstown soils have less than 25 percent clay in the lower part of the series control section. Cygnet and Houcktown soils have a densic contact within the series control section.
