In example, [fig. 21], the arrangement of the points is changed—let the student draw at the words, as follows: One, a point; two, a point above at the left; three, a point below at the left; four, draw from the point at the left to the upper point; five, from the upper point to the lower right hand point; continue to add parallel lines to complete the figure as shown.
[Figs. 22] and [23] are given as examples to practice, making first the points and then the connecting lines and afterward the parallel lines to complete the figures.
CURVED LINES.
To draw curved lines, as shown in [fig. 24]. At the word one, point; at the word two, point three inches directly above; three, at the same distance above again make a point; now draw a curve as shown, joining the middle point and the upper point; now draw the curve as shown below it; finally complete figure as shown.
