When thepencil is so used, it is usual to use the thumb as a sUding in-dicator. Examples of this use of a lead pencil are given inFigs. 42 and 43. For this lesson, the student should be provided with thefollowing: 1. Sketch pad, with a stiff back and cord. 2. Pencil, Fabers HB. 3. Lead pencil eraser. 4. Any improvised instruments, such as screen mentionedabove, and ruler for use as Mil scale. 5. Compass. Outdoor Exercises 105.
