I apply this remark indeed to those extractions of the quintessence that had for their occasion either one's more undirected though never fruitless walks and wanderings or one's earnest, one's positively pious approach to whatever consecrated ground or shrine of pilgrimage that might be at the moment in order. There was not a regular prescribed "sight" that I during those weeks neglected--I remember haunting the museums in especial, though the South Kensington was then scarce more than embryonic, with a sense of duty and of excitement that I was never again to know combined in equal measure, I think, and that it might really have taken some element of personal danger to account for. There _was_ the element, in a manner, to season the cup with sharpness--the danger, all the while, that my freedom might be brief and my experience broken, that I was under the menace of uncertainty and subject in fine to interruption. The fact of having been so long gravely unwell sufficed by itself to keep apprehension alive; it was our idea, or at least quite intensely mine, that what I was doing, could I but put it through, would be intimately good for me--only the putting it through was the difficulty, and I sometimes faltered by the way. This makes now for a general air on the part of all the objects of vision that I recover, and almost as much in those of accidental encounter as in the breathlessly invoked, of being looked at for the last time and giving out their message and story as with the still, collected passion of an only chance. This feeling about them, not to say, as I might have imputed it, _in_ them, wonderfully helped, as may be believed, the extraction of quintessences--which sprang at me of themselves, for that matter, out of any appearance that confessed to the least value in the compound, the least office in the harmony. If the commonest street-vista was a fairly heart-shaking contributive image, if the incidents of the thick renascent light anywhere, and the perpetual excitement of never knowing, between it and the historic and determined gloom, which was which and which one would most "back" for the general outcome and picture, so the great sought-out compositions, the Hampton Courts and the Windsors, the Richmonds, the Dulwiches, even the very Hampstead Heaths and Putney Commons, to say nothing of the Towers, the Temples, the Cathedrals and the strange penetrabilities of the City, ranged themselves like the rows of great figures in a sum, an amount immeasurably huge, that one would draw on if not quite as long as one lived, yet as soon as ever one should seriously get to work. That, to a tune of the most beautiful melancholy--at least as I catch it again now--was the way all values came out: they were charged somehow with a useability the most immediate, the most urgent, and which, I seemed to see, would keep me restless till I should have done something of my very own with them.
