"The sense one has of exquisite and wonderful rhythms--just beyond sound and sight! And there's a taunting suggestion of its being all there, displayed and confessed, if only one were quick enough to see it. Why, for instance, when you change the composition of a felspar almost imperceptibly, do the angles change? What's the correspondence between the altered angle and the substituted atom? Why does this bit of clear stuff swing the ray of light so much out of its path, and that swing it more? Then what happens when crystals gutter down, and go into solution. The endless launching of innumerable little craft. Think what a clear solution must be if only one had ultra-microscopic eyes and could see into it, see the extraordinary patternings, the swimming circling constellations. And then the path of a ray of polarized light beating through it! It takes me like music. Do you know anything of the effects of polarized light, the sight of a slice of olivine-gabbro for instance between crossed Nicols?" "I've seen some rock sections," said Marjorie. "I forget the names of the rocks." "The colours?" "Oh yes, the colours." "Is there anything else so rich and beautiful in all the world? And every different mineral and every variety of that mineral has a different palette of colours, a different scheme of harmonies--and is telling you something." "If only you understood." "Exactly. All the ordinary stuff of life--you know--the carts and motor cars and dusty roads and--cinder sifting, seems so blank to me--with that persuasion of swing and subtlety beneath it all. As if the whole world was fire and crystal and aquiver--with some sort of cotton wrappers thrown over it...." "Dust sheets," said Marjorie. "I know." "Or like a diamond painted over!" "With that sort of grey paint, very full of body--that lasts." "Yes." He smiled at her. "I can't help apologetics. Most people think a professor of science is just----" "A professor of science." "Yes. Something all pedantries and phrases. I want to clear my character. As though it is foolish to follow a vortex ring into a vacuum, and wise to whack at a dirty golf ball on a suburban railway bank. Oh, their golf! Under high heaven!... You don't play golf, do you, by any chance?" "Only the woman's part," said Marjorie. "And they despise us," he said. "Solomonson can hardly hide how he despises us. Nothing is more wonderful than the way these people go on despising us who do research, who have this fever of curiosity, who won't be content with--what did you call those wrappers?" "Dust sheets."
