1) This was a way of reckoning taxes, based on the amount of arable land a person held.
In 1579 an inquisition found that the fleets and mosses of Langstrothdale Chase were nott to be estymatyd by Acre Tayle with a saif conscience. That meant, I believe, that it was not possible to value rough, uncultivated land in the way that arable land was valued. The custom was explicit in Farnley Tyas in 1583 when it was said that every person should be rated towards the said laye [tax] according to his oxganges of land, taxed therefore in proportion to his holding in the town fields. In 1674 townsmen from different parts of the West Riding made a request at the Quarter Sessions that the church and poor assessments should be either by pound rent or by accar tale, and in Cudworth in 1638 an assessment made by acre tale took into account the quantitie and quallitie of the lands.
