Of the subdivisions of these great classes, the _Register_ of 1085 affords us some particulars. We find that some of the nobles are described as _milites_, soldiers; and sometimes the milites are classed with the inferior orders of tenantry. Many of the chief tenants are distinguished by their offices. We have among these the great regal officers, such as they existed in the Saxon times--the _camerarius_ and _cubicularius_, from whom we have our lord chamberlain; the _dapifer_, or lord steward; the _pincerna_, or chief butler; the constable, and the treasurer. We have the hawkkeepers, and the bowkeepers; the providers of the king's carriages, and his standard-bearers. We have lawmen, and legates, and mediciners. We have foresters and hunters. Coming to the inferior officers and artificers, we have carpenters, smiths, goldsmiths, farriers, potters, ditchers, launders, armorers, fishermen, millers, bakers, salters, tailors, and barbers. We have mariners, moneyers, minstrels, and watchmen. Of rural occupations we have the beekeepers, ploughmen, shepherds, neatherds, goatherds, and swineherds. Here is a population in which there is a large division of labor. The freemen, tenants, villeins, slaves, are laboring and deriving sustenance from arable land, meadow, common pasture, wood, and water. The grain-growing land is, of course, carefully registered as to its extent and value, and so the meadow and pasture. An equal exactness is bestowed upon the woods. It was not that the timber was of great commercial value, in a country which possessed such insufficient means of transport; but that the acorns and beech-mast, upon which great herds of swine subsisted, were of essential importance to keep up the supply of food. We constantly find such entries as "a wood for pannage of fifty hogs." There are woods described which will feed a hundred, two hundred, three hundred hogs; and on the Bishop of London's demesne at Fulham a thousand hogs could fatten. The value of a tree was determined by the number of hogs that could lie under it, in the Saxon time; and in this survey of the Norman period, we find entries of useless woods, and woods without pannage, which to some extent were considered identical. In some of the woods there were patches of cultivated ground, as the entries show, where the tenant had cleared the dense undergrowth and had his corn land and his meadows. Even the fen lands were of value, for their rents were paid in eels.
