Alas, for the frailty of human nature, Johnnie Armstrong, the strong in spirit, the guardian of morality, the prop of a wavering faith, yielded to the temptations of the world, and held only too readily that tongue which should have warned Otterburn against the snares of Belial, for, truth to tell, Johnnie made as complaisant a guardian as the most dissipated rake could have desired. The world, the flesh, and the devil was too strong a trinity for Johnnie to stand against, so he surrendered himself to the temptations of this life in the most pusillanimous manner, aiding and abetting his young master with misdirected zeal. Behold then, Angus Macjean and his leal henchman both fallen away from grace and having a good time of it at Oxford, so much so, indeed, that Otterburn was quite sorry when his father, after two years' absence, summoned him to Dunkeld Castle to grace the ceremony of his coming of age. That coming of age was a severe trial to Angus, as the guests were mostly Free Kirk ministers and their spouses, the ministers in lengthy speeches, exhorting him to follow in the footsteps of his father, _i.e_., support the Free Kirk, make large donations to the funds thereof, and entertain ministers of that following on all possible occasions. Otterburn having learnt considerable craft at Oxford, made suitable replies, promising all kinds of things which he had not the slightest idea of fulfilling, and altogether produced a favourable impression both by such guile and by a display of those educational graces with which Alma Mater had endowed him. It is needless to say that, aided by the faithful Johnnie Angus did not tell either his father or Mactab of his gay life at the University, and the result of this reticence was that the old lord, bestowing on him a small income out of the somewhat straitened finances of the Macjeans, bade him enjoy himself in London for a year, and then return to marry. To marry! Poor Angus was horror-struck at such a prospect, the more so when his father introduced him to the lady selected to be his bride, a certain Miss Cranstoun who had a good income, but nothing else to recommend her to his fastidious taste. However, being a somewhat philosophical youth, he accepted the inevitable, for he knew it would be easier to move Ben Nevis than his father, and trusting to the intervention of a kind Providence to avert his matrimonial fate, he went up to London with Johnnie to enjoy himself, which he did, but hardly in the way anticipated by Lord Dunkeld. Thinking his marriage with the plain-looking Miss Cranstoun was unavoidable, he made up his mind to see as much of life as he could during his days of freedom, and proceeded to do so to his own detriment, morally, physically and pecuniarily, when he chanced to meet with Eustace Gartney.
