"My dear Russel,—What am I expected to do with the Cat Stane? Not to review it, I hope. I have had a sniff of it already in the proceedings of the Antiquarian Society. It is a brilliant specimen of the pedantic pottering of the learned body which enables me to append to my name the A.S.S., fraudulently inverted into S.S.A. Such twaddle always excites me into feverishness. I haven't nerve for it.

"I see the grandfather of Hengist and Horsa is made out very clearly, but there seem insuperable difficulties in proving Hengist and Horsa themselves. This strikes me as a characteristic of the author's[12] profession. He has to deal with parents actual and possible, but the offspring are seen evanescently, often loom in the distance, and sometimes can't be got to exist even when most desired.—Yours truly, J.H. Burton."

Dr Simpson's really universal genius led him pretty deeply into archæology, in which he sometimes, as on the present occasion, showed more zeal than knowledge.

One of the first summers at Craighouse was enlivened by a long visit from the African traveller, Captain Speke. Dr Burton met with him in the hospitable house of his friendly publisher, the late John Blackwood, at Strathtyrum. Captain Speke was then preparing, or endeavouring to prepare, for the press, his book, the 'Discovery of the Source of the Nile.' The truly gallant Captain being more practised in exploring than in writing, Mr Blackwood suggested his going home with Dr Burton, that he might have the benefit of his advice in the formation of his materials into a book. The family at Craighouse became warmly attached to their guest. He endeared himself by his simple unassuming character, and a peculiar sweetness of temper. The sorrow at Craighouse was great on hearing, during the following autumn, of his most lamentable death. He who had escaped so many dangers—was so well accustomed to firearms—accidentally shot by his own gun while partridge-shooting near his paternal home!

While at Craighouse, Dr Burton's library gradually increased from being an ordinary room full of books, to a collection numbering about 10,000 volumes. From his earliest years Dr Burton had been a collector of books, and Craighouse led to the increase of his collection in two ways. The distance from the town was an impediment to the use of the Advocates' Library in his historical studies, and there was space at Craighouse for any number of books. There were always rooms which could be taken into occupation when wanted; and to his life's end it was a favourite amusement of Dr Burton's to construct and erect shelves for his books.

In an article in 'Blackwood's Magazine' for August 1879, there occurs the following lively description of the impression made by the library on the mind of a visitor. Before the passage quoted was published, Dr Burton had left Craighouse for Morton House, but the description evidently refers to Craighouse:—

"We have had the privilege of dropping in upon him [Dr Burton clearly being meant, though not named] in what we might call his lair, if the word did not sound disrespectful. It was in a venerable, half-castellated, ivy-grown manor-house, among avenues of ancient trees, where the light had first to struggle through the foliage before it fell on the narrow windows, in walls that were many feet in thickness. And seldom, surely, has so rich a collection been stowed away in so strange a suite of rooms. Rooms, indeed, are hardly the word. The central point, where the proprietor wrote and studied, was a vaulted chamber, and all around was a labyrinth of passages to which you mounted or descended by a step or two; of odd nooks and sombre little corridors, and tiny apartments squeezed aside into corners, and lighted either from the corridor or by a lancet-window or a loophole. The floors were of polished oak or deal; the ceilings of stone or whitewashed; and as to the walls, you could see nothing of them for the panelling of shelves and the backs of the volumes. It was books—books—books—everywhere; the brilliant modern binding of recent works relieving the dull and far more appropriate tints of work-worn leather and time-stained vellum. To the visitor it seemed confusion worse confounded; though wherever his glance happened to fall, he had assurance of the treasures heaped at random around him. But his host carried the clue to the labyrinth in his brain, and could lay his hand on the spur of the moment on the book he happened to want. And with the wonders he had to offer for your admiration, you forgot the flight of time, till you woke up from your abstraction in the enchanted library, to inquire about the manuscript that was in course of publication."

In spring Dr Burton generally spent some time in London, partly on official business, partly in literary research at the British Museum.

He was elected a member of the Athenæum Club without application or ballot, an honour which he valued highly. He delighted in the dignified and literary tone of the Club, and frequented it much when in London.

About 1867 the office of Historiographer-Royal becoming vacant, it was bestowed on Dr Burton, with a salary of £190 per annum, thus bringing his annual income to nearly £900, instead of £700. The compliment was enhanced by the fact of a Conservative Ministry being then in office. Dr Burton was a decided, though not aggressive, Liberal in politics.
