Care must be taken to keep the
polished surface of the burnisher bright and clean. When the iron is hot
enough the prints should be rubbed with a glace polish, which is sold for
this purpose, and is applied with a small wad of flannel. Then the prints
should be passed through the burnisher two or three times, the burnisher
being so adjusted that the pressure on the prints is rather light; the
degree of pressure will be quickly learned by experience, more pressure
being required if the prints have been allowed to become dry before being
polished. White castile soap will do very well as a lubricator for the
prints before burnishing, and is applied in the same manner as above.

2. Paper can be split into two or even three parts, however thin the
sheet. It may be convenient to know how to do this sometimes; as, for
instance, when one wishes to paste in a scrapbook an article printed on
both sides of the paper.
Get a piece of plate glass and place it on a sheet of paper. Then let the
paper be thoroughly soaked. With care and a little skill the sheet can be
split by the top surface being removed.
The best plan, however, is to paste a piece of cloth or strong paper to
each side of the sheet to be split. When dry, quickly, and without
hesitation, pull the two pieces asunder, when one part of the sheet will
be found to have adhered to one, and part to the other. Soften the paste
in water, and the two pieces can easily be removed from the cloth.
