Bovate
BOVATE, which has the same meaning as ox-gang, it is said, is a word used to convey to the mind as much land as a one ox-team can plough in a year. Eight bovates are said (and it is so in Lincolnshire) to have made a carucate, but the number of acres making a bovate, as in the case of the carucate, is uncertain, varying in different records from eight acres to twenty four and even to twenty seven acres, probably according as the strength of the soil varied. But if one hundred and twenty acres made a carucate of land in Lincolnshire, and eight bovates a carucate, the Lincolnshire bovate must have been fifteen acres.
