The strokes given
in this lesson, although not used as frequently as those previously given, are
1 shows the manner in which the stroke is produced. Place a piece of chalk in
the position indicated by the line below the stroke, then swing the chalk rapidly
back and forth, shortening the stroke and gradually twisting the chalk to the
vertical position. No 2 is produced in the same manner. Place the chalk
obliquely as indicated, and keep the movement oblique, shortening the stroke,
and twisting the chalk gradually to the horizontal position.
The fern is drawn
by first sketching a few main lines, No. 3, and then upon these apply the
strokes given as shown at No. 4. Hardly touch the board at first, keeping the
tones very gray; then add a few white ferns as in the sketch.
No. 6 illustrates
the same stroke used in a much bolder fashion and in a generally horizontal
direction. After applying this stroke, accent here and there with a much
shorter stroke, and add the trunk and branches.
Study the trees
given on plate 12 in connection with this illustration and notice the variety
of strokes given for the different trees.
