Thus far I have been quoting from, or referring to, authorities which are accessible to any one with an adequate command of books at his elbow--the chroniclers and the historians named, the Foedera, the Rolls of Parliament, and such authorities as whoever chooses may consult for himself. These printed authorities, which have all been consulted and looked into again and again, have told us very little, but they have given us certain notes of time--furnished us, in fact, with a _terminus a quo_. We have learnt this, at any rate, that about Christmas, 1348, the plague appeared at Westminster and its vicinity, and that it had increased alarmingly in London and elsewhere by the beginning of March, 1349. We have next to deal with that other evidence to which I have alluded--the unprinted documentary evidence ready to our hands--I mean the Institution Books in the various Diocesan Registries and the Rolls of the Manor Courts, which still exist in very great abundance, though they are rapidly disappearing from the face of the earth. It is necessary that I should trespass upon my reader's attention while I endeavour to explain the nature and the value of these two classes of documents before proceeding to deal with their testimony. I. Students of English history know that few aggressions of the Pope of Rome during the thirteenth century caused more deep discontent among the laity than those which threatened interference with their right of patronage to ecclesiastical benefices, and actually did interfere with those rights. The disgraceful recklessness with which Italians, ignorant of our language, were forced into English livings, and the best preferment was claimed for Papal nominees, produced an amount of irritation and revolt against Roman interference which had never been known before. The feeling of the laity became more and more outspoken, and at last Innocent IV. gave way, and the rights of private patronage were assured to the great lords--assured, at any rate, in word--though the Papal rescript "paltered with them in a double sense" and the quibbles and reservations, which could always be resorted to under colour of the _non obstante_ clause, constantly afforded excuse for fresh encroachments and evasions when the opportunity occurred. The jealousy of Roman interference continued to increase, and the legislation of the first half of the fourteenth century was largely taken up with enactments to guard the rights of English patrons, from the King downwards. But there was always a feeling of insecurity on the part of those who had any benefices in their gift, and a corresponding feeling on the part of those who were candidates for preferment. This led to a vicious system, whereby appointments were made with almost indecent haste to every vacant cure; institution was granted to an applicant for a benefice with the least possible delay after a vacancy had once been made known; the patron was willing to exercise his right
