This remarkable 14-volume cataloging project, covering 354 tree species, was begun by Romeyn Beck Hough in 1888 and completed in 1928 by his daughter Marjorie Galloway Hough. Hough’s exhaustive portfolio of American trees features actual thinly sliced wood samples showing transverse, radial, and tangential cross-sections of each species described. Celebrated the world over, this catalog has served as a singular reference to scientists, carpenters, architects, and historians.
