136 CORNWALL chiefs. Of these there were eight : East and West, Kerrier, Penwith, Powder, Pyder, Trigg Major, and Trigg Minor, but at the Conquest a redistribution was made in hundreds. These were Conarton, Fawiton, Pawton, Riatton, Stratton, Tibesta or Tibesterna, and Winneton. There may have been an Anglo-Saxon redistribution. But it was a rearrangement that did not last, and never commended itself to the people, and it is not easy now to ascertain what the limits were. Conarton was Penwith. Perhaps Tibesta was Powder and Winne- ton Kerrier. East and West composed one district of Wyvelshire. Cornwall was first an Earldom, and then accordingly a County, but when raised to be a Dukedom it became a Duchy. It had two chief officers, the Earl and the Sheriff, the latter appointed by the crown. The county was divided up into hundreds for ad- ministrative purposes. Each hundred was supposed roughly to contain a hundred free families. Each hundred had its own court, and every township its assembly under the reeve. But the tinners were under their own laws and officers, and their court, called the Stannary Court, sat formerly at Lostwithiel. Every manor also had its court. All the hundreds of Cornwall, except Penwith, from time immemorial belonged to the Earls of Cornwall. The hundreds and Petty Sessional Divisions are now coex- tensive, and are as follows : I . Hundred of East (Northern Division). 2. Hundred of East (Southern Division). 3. Hundred of Kerrier. 4. Hundred of Lesnewth. 5. Hundred of Penwith. 6. Hundred of Powder, East.
