Thus, for instance, in 1321, a dispute arose between _Robert de Henney_, rector of St. Martin's, and Randolph de Waltham, master of the Free Grammar School of the city of Canterbury, about the rights and privileges of their respective schools. A Special Commission was appointed by the Archbishop, including the chaplain of St. Sepulchre's, the vicar of St. Paul's, the rector of St. Mary de Castro, rector of St. Peter's, and others. The point of dispute was whether in the St. Martin's School (within the church fence or boundary) there should be more than thirteen _grammar_ scholars. The rector was limited to this number for fear of infringing on the privilege of the City Grammar School, though he was entitled to take as many scholars in reading and singing as he pleased. In fact, however, the rector took as many grammar boys as he could get, it being necessary only that when his school was visited by the city schoolmaster or his deputy, the surplus should conceal themselves for the time being. An injunction, however, was granted in the Archbishop's Court to restrain the rector from taking more than his bare thirteen. This is an extremely interesting record, because it shows that there were two flourishing public schools in Canterbury, probably the most ancient Grammar Schools in England, early in the fourteenth century; and that the pupils _paid_ for their teaching, and learnt other subjects besides grammar. Thorn, the monk of St. Augustine's, tells us also an amusing story of how _John de Bourne_, rector of St. Martin's, aided in the escape of one Peter de Dene from St. Augustine's Monastery by placing ladders against the monastery walls. They then rode on horseback together to Bishopsbourne, but Peter was at length recaptured. In the fourteenth century we find no less than three rectors who were instituted to St. Martin's by the Prior of Christ Church during a vacancy in the see of Canterbury. We have already mentioned the difficulty of obtaining information concerning the church in the Middle Ages, owing to its being exempt from the jurisdiction of the Archdeacon of Canterbury, and therefore not included in the Archidiaconal Registers, while the Archbishop's Visitations of the diocese were not, as a rule, parochial. By a lucky chance, however, we find some entries in Archbishop Warham's Visitation in 1511, one of which is to the effect that the churchwardens had not furnished accounts for five years, though they had received various monies for keeping graves in order. They were ordered to furnish accounts before the Feast of Purification, under pain of excommunication, &c.
