OBLIQUE LINES.
In drawing oblique straight lines as shown in [fig. 17], at the word one let the student make the lower point; at the word two the upper, a little to the right of the lower; at the word three draw a line quickly from the upper to the lower point. In pronouncing the words one, two, three, let the student make the additional parallel lines.
As shown in [fig. 18], at the word one make the lower point; at the word two the upper point, a little to the left; at the word three draw a line rapidly from the upper to the lower point, and “timing” the process by repeating one, two, three, make the additional parallel lines.
