Of less interest to the general reader, though too important a part of Ruskin's life and work to be passed over without mention, are his studies in Mineralogy. We have heard of his early interest in spars and ores; of his juvenile dictionary in forgotten hieroglyphics; and of his studies in the field and at the British Museum. He had made a splendid collection, and knew the various museums of Europe as familiarly as he knew the picture-galleries. In the "Ethics of the Dust" he had chosen Crystallography as the subject in which to exemplify his method of education; and in 1867, after finishing the letters to Thomas Dixon, he took refuge, as before, among the stones, from the stress of more agitating problems.
In the lecture on the Savoy Alps in 1863 he had referred to a hint of Saussure's that the contorted beds of the limestones might possibly be due to some sort of internal action, resembling on a large scale that separation into concentric or curved bands which is seen in calcareous deposits. The contortions of gneiss were similarly analogous, it was suggested, to those of the various forms of silica. Ruskin did not adopt the theory, but put it by for examination in contrast with the usual explanation of these phenomena, as the simple mechanical thrust of the contracting surface of the earth.
In 1863 and 1866 he had been among the Nagelflüh of Northern Switzerland, studying the puddingstones and breccias. He saw that the difference between these formations, in their structural aspect, and the hand-specimens in his collection of pisolitic and brecciated minerals was chiefly a matter of size; and that the resemblances in form were very close. And so he concluded that if the structure of the minerals could be fully understood a clue might be found to the very puzzling question of the origin of mountain structure.
Hence his attempt to analyze the structure of agates and similar banded and brecciated minerals, in the series of papers in the Geological Magazine;[15] an attempt which though it was never properly completed, and fails to come to any general conclusion, is extremely interesting as an account of beautiful and curious natural forms till then little noticed by mineralogists.
A characteristic anecdote of this period is preserved in "Arrows of the Chace."
"The Daily Telegraph of January 21st, 1868, contained a leading article upon the following facts. It appeared that a girl, named Matilda Griggs, had been nearly murdered by her seducer, who, after stabbing her in no less than thirteen places, had then left her for dead. She had, however, still strength enough to crawl into a field close by, and there swooned. The assistance she met with in this plight was of a rare kind. Two calves came up to her, and disposing themselves on either side of her bleeding body, thus kept her warm and partly sheltered from cold and rain. Temporarily preserved, the girl eventually recovered, and entered into recognizances, under a sum of forty pounds, to prosecute her murderous lover. But 'she loved much,' and failing to prosecute, forfeited her recognizances, and was imprisoned by the Chancellor of the Exchequer for her debt. 'Pity the poor debtor,' wrote the Daily Telegraph, and in the next day's issue appeared the following letter, probably not intended for the publication accorded to it. 'Sir,—Except in 'Gil Blas,' I never read of anything Astræan on the earth so perfect as the story in your fourth article to-day. I send you a cheque for the Chancellor. If forty, in legal terms, means four hundred, you must explain the farther requirements to your impulsive public.
"'I am, Sir, your faithful servant, 'J. RUSKIN.'"
The writer of letters like this naturally had a large correspondence, beside that which a circle of private friends and numberless admirers and readers elicited. About this time it grew to such a pitch that he was obliged to print a form excusing him from letter-writing on the ground of stress of work. And indeed, this year, though he did not publish his annual volume, as usual, he was fully occupied with frequent letters to newspapers, several lectures and addresses, a preface to the reprint of his old friend Cruikshank's "Grimm," and the beginning of a new botanical work, "Proserpina," in addition to the mineralogy, and a renewed interest in classical studies. Of the public addresses the most important was that on "The Mystery of Life and its Arts," delivered in the theatre of the Royal College of Science, Dublin (May 13th), and printed in "Sesame and Lilies."
After this visit to Ireland he spent a few days at Winnington; and late in August crossed the Channel, for rest and change at Abbeville. For the past five years he had found too little time for drawing; it was twenty years since his last sketching of French Gothic, except for a study (now at Oxford), of the porch at Amiens, in 1856. He took up the old work where he had left it, after writing the "Seven Lamps," with fresh interest and more advanced powers of draughtsmanship as shown in the pencil study of the Place Amiral Courbet, now in the drawing school at Oxford.
The following are extracts from the usual budget of home letters; readers of "Fors" will need no further introduction to their old acquaintance, the tallow-chandler.
