PERPENDICULAR LINES.

Fig. 15 shows six lines--upright and perpendicular, with points or

“dots” indicated at the top and bottom of each line; to draw these,

proceed thus:

[Illustration: Fig. 15.]

[Illustration: Fig. 16.]

The learner should stand with his right shoulder opposite the board, and

the weight of the hand and the arm should be allowed to fall naturally;

now, make on the board two points, one being six inches above the other,

these being merely “dots,” shown at the ends of the lines, figs. 15,

etc., and made with two motions; the line between the points should now

be drawn not too quickly from the upper to the lower point; three

movements of the hand and arm complete the line; to draw the other five

lines the movements have simply to be repeated.

If the student pronounces to himself “one,” “two,” “three,” at each

motion, it will be helpful; in this exercise, fig. 15, the aim is to

make six lines, each line being parallel to the first. Again, in the

example, it is intended that the lower point should be made first, next

the upper, and lastly the line drawn from the upper to the lower point,

but the order may be reversed; at _one_ the upper point, at _two_ the

lower, at _three_ the stroke upwards to complete the line.
