or from a tube of oil paint. Take up a very little color on the
dabber, and work it about on the center of the paper for some time, till
the dabber is evenly covered with a thin coating. A little oil can be used
to dilute or moisten the color if necessary. Then put your leaf down on
the paper and dab some color evenly over both sides. Place it then between
the pages of a folded sheet of paper (unglazed is best), and rub the paper
above it well all over with the finger. Open the sheet, remove the leaf,
and you will have an impression of each side of the leaf. Any color may be
used. Burnt or raw sienna works the most satisfactorily.

DRYER FOR RULING INKS.

Ruling inks are made to dry quickly by using half a gill of methylated
spirits to every pint of ink. The spirit is partly soaked into the paper
and partly evaporates; it also makes the lines firm.
