AN ANNOTATED BIBLIOGRAPHY OF FIGURE IN WOOD Harold O. Beals and Terry C. Davis This publication presents abstracts of articles concerning figure in wood some of which have not been included in other bibliographies. An attempt has been made to include all references on this subject except those in Russian. Principal sources of information were major international journals in wood science and technology and personal communication with active researchers in this field. Since many references are in Scandinavian languages and some journals are obscure and generally not available in many libraries in the United States, a library source has been provided. These abstracts indicate that the major portion of work on figure in wood in the United States was done many years ago and that little current research on this subject is being conducted. European literature indicates a concentration on the "Masur" figure, a type that has not been reported in North America. This bibliography represents a portion of a larger study concerning figure in wood that will be published at a later date. Anonymous 1952. Sloping Grain in Timber. Comm. Scient. and Ind. Res. Org.

A series of four articles concerning figure formation. Part I considers anatomical aspects of figure formation such as grain, texture, structure, and color. Part II considers figure that occurs in different parts of trees and in more detail with various figure types formed by curly, wavy, and interlocked grain. Part III is a continuation on variations in structure and effects of conversion on emphasizing figures. Part IV discusses the more common distinctive figure classifications. Beals, H. 0. and T. C. Davis 1966. Fiddleback and Quilted Figures in Wood. J. Ala. Acad. of Sci. 37:263. Fiddleback figure occurs on the radial face of certain wood while quilted figures appears on tangential faces. Fiddleback figure is regular in occurrence and exhibits a corrugated appearance when woods are split radially Quilted figures are usually irregular and appear as convex intersecting areas on one side and concave surfaces on the other.

The Anatomy of Bird's-Eye Figure in Sugar Maple (Acer saccharum Marsh). Unpublished progress report. Dept. of For. Mich. St. Coll. 19 pp. 16 photos. (Copy from Author). A preliminary study of the anatomy of bird's-eye figure in hard maple. The formation of "pegs" from the phloem into the xylem and an enlargement of rays are illustrated. "Stone cells" are a universal feature associated with the indented portion of "the eye" in phloem. Pit-like depressions in the bark of old bird's-eye trees result from the periderm following contours of the initial phloem indentation. Bitters, W. P. and E. R Parker. 1953.
