And Herbert did go,--almost without uttering a word of adieu. What could he say in answer to such threats as these? That his cousin was in every way unreasonable,--as unreasonable in his generosity as he was in his claims, he felt convinced. But an unreasonable man, though he is one whom one would fain conquer by arguments were it possible, is the very man on whom arguments have no avail. A madman is mad because he is mad. Herbert had a great deal that was very sensible to allege in favour of his views, but what use of alleging anything of sense to such a mind as that of Owen Fitzgerald? So he went his way without further speech. When he was gone, Owen for a time went on walking his room, and then sank again into his chair. Abominably irrational as his method of arranging all these family difficulties will no doubt seem to all who may read of it, to him it had appeared not only an easy but a happy mode of bringing back contentment to everybody. He was quite serious in his intention of giving up his position as heir to Castle Richmond. Mr. Prendergast had explained to him that the property was entailed as far as him, but no farther; and had done this, doubtless, with the view, not then expressed, to some friendly arrangement by which a small portion of the property might be saved and restored to the children of Sir Thomas. But Owen had looked at it quite in another light. He had, in justice, no right to inquire into all those circumstances of his old cousin's marriage. Such a union was a marriage in the eye of God, and should be held as such by him. He would take no advantage of so terrible an accident.
