BEGINNING WOODWORK. Clinton S. Van Deusen, M. E. 99 pp. 6x9 inches, oblong. 10 illustrations by E. V. Lawrence. Cloth, $1.00. The Manual Arts Press, Peoria, III. This book is intended as a definite statement of steps that may be followed by a beginner in learning the fundamental principals of woodworking. This is accomplished by a number of specific examples, and from the experience gained in doing these the pupil should be able to accomplish without difficulty other work of which the examples given stand as types. The number of examples given is so small, however, that the beginner must seek other sources of information before his appetite for designs is likely to be satisfied. As a suggestion for future editions, an appendix of about a dozen designs with dimensions would be recommended as rounding out the book. The information given is clearly expressed and the illustrations are well done.
