"For drawing ink lines other than arcs of circles, the ruling pen is used. It should be held as nearly perpendicular to the board as possible, bearing lightly against the T square or triangle, along the edge of which the line is drawn. After a little practice, this position will become natural, and no difficulty will be experienced." — Hallock, 1905
