   “1890, Ambrose Bierce, “An Occurrence at Owl Creek Bridge”, in Tales of Soldiers and Civilians, New York: Lovell, Corvell & Co., 1891, p. 32, He looked at the forest on the bank of the stream, saw the individual trees, the leaves and the veining of each leaf—saw the very insects upon them, the locusts, the brilliant-bodied flies, the gray spiders stretching their webs from twig to twig.”

   “His downcast eyes followed the silent veining of the oaken slab. Beauty: it curves: curves are beauty.”

   “Surrounding, a system of marble paneling applies to the walls, as we know wood. Sheets of stone, cut and cut again so that the veining of each piece may form symmetrical pattern with its neighbor, alternate with bands of other marbles set in delicately notched beveling.”
