Hmm, staring at the applotment book, I'm not sure what to make of the columns and am having trouble decoding all the values.
It is relatively straightforward, once you know the units.
The first three columns are the valuator's estimation of the relative quality of different portions of land - 1st, 2nd and 3rd class land. The fourth colums is for the area of any included roads, while the 5th column is the total area of each holding. The units used for land area seem to cause some confusion these days - it is in A-R-P, that is Acres, Roods and Perches. There being 40 perches in a rood, and 4 roods in an acre. So there are 160 perches in in acre.
The 5th, 6th and 7th columns are the actual tythe valuation of each lot as a monetary value
The 5th column being how much was due per annum to the vicar
The 6th column how much was due to the lay impropiator, and
The 7th column is the total amount due as tythe from that holding.
These columns are in £-s-d (pronounced LSD).
Where £ is pounds, s is shillings, and d is pence.
There were 12 pennies in a shilling, and 20 shillings in a pound. So 240 pennies in a pound.
