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.

dimples is attributed to resin blisters pressing into the cambial zone, thus
retarding xylem formation in the vicinity of the blisters. (See Chafe, S.C.)

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.

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 Unpublished progress report.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.

inner bark, but caused by sclerids in spruce.
