PROBLEMS in MECHANICAL DRAWING.
By Charles A. Bennett. With drawings made by Fred D. Crawshaw.
This book consists of 80 plates and a few explanatory notes, and is bound in heavy paper covers with brass fasteners. Its purpose is to furnish teachers of classes beginning mechanical drawing with a large number of simple, practical problems. These have been selected with reference to the formation of good habits in technique, the interest of the pupils, and the subjects generally included in a grammar and first-year high school course. Each problem given is unsolved and therefore in proper form to hand to the pupil for solution. Price, $1.00. Board covers, $1.20.
