In case hour periods have to be used, two such periods would equal one of the longer ones. Definite instructions, by means of a rough sketch on the blackboard as to the location of the views in relation to the border line and a few of the main dimensions, will save much time. See Fig. ii.

Kind of paper to use. — If the drawings are to be done with a rule and pencil only, the edges of the paper used must form a rectangle with square corners, as the main outline of the drawing will have to be put in by measuring from the edges of the paper. A good quality of fairly heavy, smooth, white linen bond paper, 8i'' X ii'', is satisfactory for these exercises, or, better still, pads of the heavier white drawing paper of about the same size, or preferably a little larger, which can be had through the bookstores.
