In 1351, Abbot Reginald was charged, as if it were a crime, and found guilty, of having within two years collected of his own money, and from the Abbots of Boyle, Knockmoy, Bective, and Cashel, and of having remitted the sum of 664 florins to the Abbot of Clairvaux, while war was being waged between England and France. But there was no treason or treasonable intent in that; for the money was to defray the current expenses of the Order, and was levied off every monastery in proportion to the resources of each. Richard, Coeur de Lion, Alexander II. of Scotland, and Bela IV. of Hungary had, in their day, contributed largely to this fund. In 1358, the Abbot of Mellifont made good his claim to three weirs upon the Boyne, at Rosnaree, Knowth, and Staleen; but, in 1366, he was indicted at Trim, for erecting an unlawful weir at Oldbridge, when the Jury found against him, and he was ordered to reduce the weir to a certain breadth and space, and he, himself, was sentenced to a term of imprisonment; but, on his paying a fine of £10 to Roland de Shalesford, the sheriff of the Co. Meath, this sentence was commuted. Ten years later, John Terrour, successor to this Abbot, was sued for obstructing the King's passage of the Boyne. In the years 1373 and 1377, the Abbot was summoned to attend Parliaments held at Dublin and Castledermot respectively. In the former Parliament, one hundred shillings were ordered to be levied from him, as his portion of the subsidy granted to the Lord Justice, William de Windesore, by the same Parliament. In 1380, the King gave a special mandate that no _mere_ Irishman should be admitted to profession in this abbey. In 1381 and 1382, the Abbot attended Parliaments held in Dublin, and in 1400, the King granted a royal confirmation of all the land, manors, and liberties, bestowed on the abbey by former charters; and in 1402, he pardoned the Abbot and monks for their having admitted Irishmen to profession. However, they were mulcted in the sum of £50. In 1415, Leynagh Bermingham, William Davison, and John D'Alton were committed to the custody of the Abbot to be kept by him as hostages for the allegiance of their respective fathers. In 1424, the Abbot, with the Archbishop of Armagh and Nicholas Taaffe, was appointed Justice and Conservator of the Peace for the Co. Louth.
