Subjects: Agricultural and other produce and its value

It may be that the value of produce as claimed in tithe causes is over-stated to increase the value of the claim, and often values were not precisely given.

Some definitions may also be useful:

Acre – the Cheshire acre was 10,240 square yards, as opposed to a statute acre of 4,840 square yards. The Cheshire acre was also used in parts of south Lancashire.
Thrave – twenty four sheaves.
