[W]hen an estate is so heavily burdened by an accumulation of debts inherited by its present possessor from the unwisdom of their forefathers. A point is ever reached … when the interest on money borrowed can no longer be paid and the lands themselves have to be sold. This in brief is what had happened not only with the lands we speak to you of, but of nearly all the lands which march with Ardkinglass. You will all of you recollect that it was but some 10 years ago that the neighbouring estate of Strachur which (with that of Ardgarten) was held for at least 9 centuries by a branch of our race passed into other hands. Drimsynie, Carrick, Ardentinny and Kilmun and even Dunoon all once part of the vast Barony of Ardkinglass and all held by younger sons of the parent stock have long since passed away, with the single exception of Dunoon which is still held by one of the old race. And though it seem but a span in the lifetime of a planet, and though the hills that keep watch, in their own unchanging silence, over the changing ownership of the glens, shall smile at the thought it seems a long time in the history of the race when we look back at the far off day when Cailein Oig first Laird of Ardkinglass with his three tall sons settled, in the place where in obedience to a predicted omen his hamper strings should snap.
