Acre No. 10 is divided, according to Gunter’s decimal system, into 10 square chains, each 4 rods square.
4. Feudal Land-Measures
In ancient Egypt land was surveyed by a State department, but other Eastern Kingdoms, even of the present time, are less advanced. There is a simple system of taxing each plough. This was approximately the medieval system, as we see in the Domesday revenue-survey, the great record of the plough-lands and rental of England. Estates are thus described:
2-1/2 hides; land for 1-1/2 ploughs. There is 1 plough with 4 bordars and 4 serfs. Worth 30s.
2 hides, land for 2 ploughs, 30 acres meadow. Worth 60s.
4 hides, 1-1/2 virgates; land for 10 ploughs. Now worth 14 li., formerly at 17 li.
In some parts the ‘knight’s fee’ was reckoned at 480 acres (4 hides) worth 40 shillings a year. On this valuation—
The pound-land, librata terræ, was 240 acres.
The shilling-land, solidata terræ, was 12 acres.
The penny-land, denariata terræ, was 1 acre.
