were never raised, and never shall be, but by men who love and aid each other in their weakness;--that all their interlacing strength of vaulted stone has its foundation upon the stronger arches of manly fellowship, and all their changing grace of depressed or lifted pinnacle owes its cadence and completeness to sweeter symmetries of human soul. LECTURE V. THE WORK OP IRON, IN NATURE, ART, AND POLICY. _A Lecture Delivered at Tunbridge Wells, February, 1858._ When first I heard that you wished me to address you this evening, it was a matter of some doubt with me whether I could find any subject that would possess any sufficient interest for you to justify my bringing you out of your comfortable houses on a winter's night. When I venture to speak about my own special business of art, it is almost always before students of art, among whom I may sometimes permit myself to be dull, if I can feel that I am useful: but a mere talk about art, especially without examples to refer to (and I have been unable to prepare any careful illustrations for this lecture), is seldom of much interest to a general audience. As I was considering what you might best bear with me in speaking about, there came naturally into my mind a subject connected with the origin and present prosperity of the town you live in; and, it seemed to me, in the out-branchings of it, capable of a very general interest. When, long ago (I am afraid to think how long), Tunbridge Wells was my Switzerland, and I used to be brought down here in the summer, a sufficiently active child, rejoicing in the hope of clambering sandstone cliffs of stupendous height above the common, there used sometimes, as, I suppose, there are in the lives of all children at the Wells, to be dark days in my life--days of condemnation to the pantiles and band--under which calamities my only consolation used to be in watching, at every turn in my walk, the welling forth of the spring over the orange rim of its marble basin. The memory of the clear water, sparkling over its saffron stain, came back to me as the strongest image connected with the place; and it struck me that you might not be unwilling, to-night, to think a little over the full significance of that saffron stain, and of the power, in other ways and other functions, of the steelly element to which so many here owe returning strength and life;--chief as it has been always, and is yet more and more markedly so day by day, among the precious gifts of the earth. The subject is, of course, too wide to be more than suggestively treated; and even my suggestions must be few, and drawn chiefly from my own fields of work; nevertheless, I think I shall have time to indicate some courses of thought which you may afterwards follow out for yourselves if they interest you; and so I will not shrink from the full scope of the subject which I have announced to you--the functions of Iron, in Nature, Art, and Policy.
