The ingenious licentiate Francisco de Ubeda, when he commenced his history of 'La Picara Justina Diez,'--which, by the way, is one of the most rare books of Spanish literature,--complained of his pen having caught up a hair, and forthwith begins, with more eloquence than common sense, an affectionate expostulation with that useful implement, upbraiding it with being the quill of a goose,--a bird inconstant by nature, as frequenting the three elements of water, earth, and air indifferently, and being, of course, 'to one thing constant never.' Now I protest to thee, gentle reader, that I entirely dissent from Francisco de Ubeda in this matter, and hold it the most useful quality of my pen, that it can speedily change from grave to gay, and from description and dialogue to narrative and character. So that if my quill display no other properties of its mother-goose than her mutability, truly I shall be well pleased; and I conceive that you, my worthy friend, will have no occasion for discontent. From the jargon, therefore, of the Highland gillies I pass to the character of their Chief. It is an important examination, and therefore, like Dogberry, we must spare no wisdom. The ancestor of Fergus Mac-Ivor, about three centuries before, had set up a claim to be recognised as chief of the numerous and powerful clan to which he belonged, the name of which it is unnecessary to mention. Being defeated by an opponent who had more justice, or at least more force, on his side, he moved southwards, with those who adhered to him, in quest of new settlements, like a second AEneas. The state of the Perthshire Highlands favoured his purpose. A great baron in that country had lately become traitor to the crown; Ian, which was the name of our adventurer, united himself with those who were commissioned by the king to chastise him, and did such good service that he obtained a grant of the property, upon which he and his posterity afterwards resided. He followed the king also in war to the fertile regions of England, where he employed his leisure hours so actively in raising subsidies among the boors of Northumberland and Durham, that upon his return he was enabled to erect a stone tower, or fortalice, so much admired by his dependants and neighbours that he, who had hitherto been called Ian Mac-Ivor, or John the son of Ivor, was thereafter distinguished, both in song and genealogy, by the high title of Ian nan Chaistel, or John of the Tower. The descendants of this worthy were so proud of him that the reigning chief always bore the patronymic title of Vich Ian Vohr, i.e. the son of John the Great; while the clan at large, to distinguish them from that from which they had seceded, were denominated Sliochd nan Ivor, the race of Ivor.
