THE INVASION OF AILSA CRAIG Although in the possession of the historic family of Kennedy, to the head of which it gives his title, Ailsa Craig, the imposing "ocean pyramid" that rises in solitary grandeur to a height of over 1100 feet above the waters of the Firth of Clyde, does not figure prominently in the annals of the country, nor in the special records of the district to which it belongs. Its whole story consists of a single episode, which, though hardly noticed by modern historians, created some excitement, both in Scotland and in England, at the time of its occurrence, and may be read with interest at the present day. That incident, the invasion of Ailsa Craig, which it is here intended to relate on the authority of contemporary documents, takes us back to the year 1597. The chief actors in it were Hugh Barclay, Laird of Ladylands, an Ayrshire gentleman of good family, whose estate was situated in the neighbourhood of Irvine, and Andrew Knox, "minister of God's worde at Paselye". Though originally a member of the Presbyterian Church, Ladylands had made "defectioun and apostacie fra the said trewe religioun". In the correspondence of the time he is usually to be found figuring in the lists of those whom it was customary to describe as "practising Papists", a designation not undeserved in his case, for amongst the religious enthusiasts who devoted themselves to the restoration of the old religion none displayed a greater fixity of purpose, a more unscrupulous contempt for the law, or a more reckless disregard of personal danger. Andrew Knox, on the other hand, in spite of his peaceful calling, gave proof of equal determination and equal audacity in the fulfilment of the self-imposed mission of hunting down "Jesuitis, seminarie preistis, and suspect trafficquaris with the King of Spain, and utheris foreynaris". The plotting of the laird and the counter-plotting of the minister had more than once brought the two men into personal conflict. Indeed, so far as extant documents go, the career of the one is practically identified with the career of the other.
