his prerogatives he was entitled to banquet on the first of August, on the fish of the Boyne, fruit from the Isle of Man, cresses from the Brosna river, venison from Naas, and to drink the water of the well of Talla: in other words, he was entitled to eat on that day, of the produce, whether of earth or water, of the remotest bounds, as well as of the very heart of his mensal domain. The King of Leinster was "prohibited" from upholding the Pagan ceremonies within his province, or to encamp for more than a week in certain districts; but he was "privileged" to feast on the fruits of Almain, to drink the ale of Cullen, and to preside over the games of Carman, (Wexford.) His colleague of Munster was "prohibited" from encamping a whole week at Killarney or on the Suir, and from mustering a martial host on the Leinster border at Gowran; he was "privileged" to pass the six weeks of Lent at Cashel (in free quarters), to use fire and force in compelling tribute from north Leinster; and to obtain a supply of cattle from Connaught, at the time "of the singing of the cuckoo." The Connaught King had five other singular "prohibitions" imposed on him—evidently with reference to some old Pagan rites—and his "prerogatives" were hostages from Galway, the monopoly of the chase in Mayo, free quarters in Murrisk, in the same neighbourhood, and to marshal his border-host at Athlone to confer with the tribes of Meath. The ruler of Ulster was also forbidden to indulge in such superstitious practices as observing omens of birds, or drinking of a certain fountain "between two darknesses;" his prerogatives were presiding at the games of Cooley, "with the assembly of the fleet;" the right of mustering his border army in the plains of Louth; free quarters in Armagh for three nights for his troops before setting out on an expedition; and to confine his hostages in Dunseverick, a strong fortress near the Giant's Causeway. Such were the principal checks imposed upon the individual caprice of Monarchs and Princes; the plain inference from all which is, that under the Constitution of Patrick, a Prince who clung to any remnant of ancient Paganism, might lawfully be refused those rents and dues which alone supported his dignity. In other words, disguised as it may be to us under ancient forms, "the Book of Rights" establishes Christianity as the law of the land. All national usages and customs, not conflicting with this supreme law, were recognized and sanctioned by it. The internal revenues in each particular Province were modelled upon the same general principle, with one memorable exception—the special tribute which Leinster paid to Munster—and which was the cause of more bloodshed than all other sources of domestic quarrel combined. The origin of this tax is surrounded with fable, but it appears to have arisen out of the reaction which took place, when Tuathal, "the Legitimate," was restored to the throne of his ancestors, after the successful revolt of the Belgic bondsmen.
