The amateur who desires to learn wood carving without the direction and help of an instructor, will find this work of great help, and a careful following of the instructions given therein should result in the at-tainment of at least a fair measure of success.

An important feature is the extended treatment of the care and uses of tools peculiar to the different classes of wood carving, as well as those common to all.

The examples given to illustrate the several chap ters are decidedly better than are to be found in most books upon this subject, which, together with the completeness with which the various operations are treated, make the book one which can be cordially recommended to the beginner.
