How to Make Pencil Writing Ineffaceable.

It is said that pencil drawings may be rendered ineffaceable by this simple process: Slightly warm a sheet of ordinary drawing paper; then place it carefully on the surface of a solution of white resin in alcohol, leaving it there long enough to become thoroughly moistened. Afterward dry it in a current of air. Paper prepared in this way has a very smooth surface. In order to fix the drawing, the paper is to be warmed for a few minutes. This method may prove useful for the preservation of plans or designs, when the want of time or any other cause will not allow of the draughtsman reproducing them in ink. A simpler plan than the above, however, is to brush over the back of the paper containing the charcoal or pencil sketch a weak solution of white shellac in alcohol.
