Do not dwell upon them long atany one time. As so man}- designs are constructedon a geometrical basis, the pupil will have occasionto draw the given figures quite frequently in the reg-ular course of these lessons. It will be an excellentpractice now and then to require your pupils to tellyou how the figures should be drawn, step by step,while 3ou draw them on the blackboard. But remember that the drawing of these geo-metrical forms by freehand is in part educational,and in part to enable the pupil to secure an approx-imate accuracy when instruments are not available,or when perfect accuracy is not required. Everyperson requiring a perfectly accurate hexagon oroctagon will draw it as only it can be drawn, viz.,by mechanical means.
