The image in our blog heading is a mosaic of wood “cubes” prepared by Mr. Arnold Day back in the 1970’s. These cubes were painstakingly prepared by sectioning with a sliding microtome the three surfaces; radial, tangential and cross section. Images were then acquired with the ETEC scanning electron microscope. These were featured on the cover of the book, Wood Structure and Identification by H. A. Core, W. A. Côté and A. C. Day, Syracuse University Press, 1979.
