The details maythen be drawn into the gray mass. The pencil may be used in asimilar manner. Chalk-modeling has been largely used in the illustration ofthis little book. The sketches have in all cases been copied fromthe blackboard work, and are intended to show the general effectsthat may be produced by the use of the flat side of the pictures are drawn in less than one minute each, with effectsrequiring much longer time when the attempt is made to repro-duce them.
