III. All inhabitants of a borough were also deeply interested in the preservation of the boundaries which marked the extent of their dominions, the “liberties” within which they could enforce their own law, regulate trade, and raise taxes. Century after century the defence of the frontier remained one of the urgent questions of town politics, insistent, perpetually recurring, now with craft and treachery, now with violence and heated passion breaking into sudden flame. Every year the mayor and corporation made a perambulation of the bounds and inspected the landmarks;[242] the common treasure was readily poured out if lawsuits and bribes were needed to ascertain and preserve the town’s rights; and if law failed, the burghers fell back without hesitation on personal force. In Canterbury the town and the convent of Christ Church were at open war about this question as about many others. The monks remained unconvinced even though the mayor and council of thirty-six periodically “walked the bounds,” giving copper coins at the various turning points to “divers children” that they might remember the limits of the franchise, while they themselves were refreshed after their trouble by a “potation” in a field near Fordwich. At one time the quarrel as to the frontier raged round a gigantic ash-tree—the old land-mark where the liberties of the city touched those of Fordwich—which was in 1499 treacherously cut down by the partizans of Christ Church; the Canterbury men with the usual feastings and a solemn libation of wine set up a new boundary stone. At another time the dispute shifted to where at the west gate of the town the river wound with uncertain and changing course that left frontiers vague and undefined. A low marshy ground called the “Rosiers” was claimed by the mayor as under his jurisdiction, while the prior asserted that it was within the county of Kent; and for thirty years the question was fought out in the law courts. On July 16th, 1500, the mayor definitely asserted his pretensions by gathering two hundred followers arrayed in manner of war to march out to the Rosiers. There certain monks and servants of the prior were taking the air; one protested he had been “late afore sore sick and was walking in the field for his recreation”; another had a sparrow-hawk on his fist, and the servants declared they were but peaceful haymakers; but all had apparently gone out ready for every emergency, for at the appearance of the enemy bows and arrows, daggers, bills, and brigandiers, were produced from under the monks’ frocks and the smocks of the haymakers. In the battle that followed the monks were beaten, and the citizens cut down willows and stocked up the dyke made in the river by the convent; and boldly proceeded the next day[243] to other outrages. The matter was brought to judgement, and a verdict given against the mayor for riot—a verdict which that official, however, lightly disregarded. It was in vain that the prior, wealthy and powerful as he was, and accustomed to so great influence at court, appealed to the Star Chamber to have the penalty enforced, for no further steps were taken by the government. It probably judged wisely, since in such a matter the temper of the citizens ran high; and the rectification of frontiers was resented as stoutly as a new delimitation of kingdoms and empires to-day.
