24th. A different kind of plough was used between New Karleby and Vasa. It was always drawn by a horse, rarely by an ox. If an ox was used, it pulled like a horse and used the same harness; no belly-band. On its back, however, there was a girth like a saddle-girth resting against the withers so that the harness would not slide forward on the ox. This was not used on horses.
