Law Courts 181 In the same reign, there is evidence of specially full meetings of the hundred court, held twice a year when necessary, whose main purpose was view of frankpledge.1 This was an examination of the pledge groups to see if they were full and properly organised, and the special meetings of these courts held for such purpose over which the sheriffs presided must be considered essentially king's courts; they were to enforce a piece of police ma- chinery devised by the king. Thus during Henry Us reign, both shire and hundred courts were, upon occasion,, king's courts, and were always potentially such. By the Assize of Clarendon, 1166, a new power was given the sheriff, the use of the presenting jury; and it has been suspected that Henry II/s adoption of this procedure in his own courts, was suggested by the frankpledge system. "The machinery was apt for the purpose; the duty of producing one's neighbour to answer accusations could well be converted into the duty of telling tales against him.7'2 The sheriff used this jury in the semiannual meetings of the hundred court, where view of frankpledge was held, criminal cases were initiated that were to be concluded before the itinerant justices, and many minor criminal matters disposed of. This court caine to be known as the sheriff's tourn.3 It was his semiannual visi- tation of the hundreds of his shire for the purpose of crimi- nal jurisdiction. In such a court, where he was as dis- tinctly a royal justice as the itinerant justice was in his court, the sheriff naturally assumed more of the judging function; he was not a mere presiding officer or one who looked out for the royal interests in a court that derived its authority from a source outside the long, as he had been in the old communal courts. This being the character some related passages in the Leges Henrici Primi in American Historical Review, viii., pp. 487-490, 1 For the origin of frankpledge, see above, pp. 67-69, 109, no. 2 Maitland, Introduction to vol. ii. of the SeUen Society Publications, p. xxxvii. 3 The word tourn or turn was not, until after the thirteenth centuiy, used as a sufficient description of the court; it was Curia msm jranci- plegii domini regis apud B. cor am mc&comiti in turno suo.
