oiling water over the type,
and allow it to stand for about half an hour. Repeat, if necessary, until
the desired effect has been obtained.
LAYING TYPE.
The page as received from the founder, should be carefully unwrapped, and,
after having been placed on a galley, soaked thoroughly with thin soap
water, to prevent adhesion after the types have been used a short time;
then, with a firm rule or reglet, as many lines should be lifted as will
make about an inch in thickness, and, placing the rule close upon one side
of the bottom of the proper box, slide off the lines gently, taking care
not to rub the face against the side of the box. Proceed then with
successive lines till the box is filled. Careless compositors are prone to
huddle new type together, and grasping them by handfulls plunge them
pell-mell into the box, rudely shaking them down to crowd in more. This
should never be allowed, as shaking does more injury to type than press
wear. The type left over should be kept standing on galleys in regular
order till the cases need to be again filled or sorted.
TO FIX BRONZE COLORS ON GLASS.
Bronze colors can be fixed upon glass or porcelain by painting the
articles with a concentrated solution of potash water glass of 30 deg. B., and
dusting them with the bronze powder. The latter adheres so firmly that it
will not be affected by water, and may be polished with steel or agate.
TO DESTROY BOOK WORMS.
For the destruction of book worms, put the books into a case which closes
pretty well, and keep a saucer supplied with benzine within it for some
few weeks. Worms, larvae, eggs--all are said to be got rid of.
TINNING PAPER AND CLOTH.
The following is a method of tinning paper and cloth:--Zinc powder is
ground with an albumen solution, the boiling mixture is then spread over
the tissue by means of a brush, when dry, the layer is fixed by dry steam,
which coagulates the albumen, and the tissue is then taken through a
solution of tin. Metallic tin is reduced, and sets in a very thin layer.
The tissues of paper are then washed, dried and hot pressed.
CARE OF BOOKS.
Books should be shelved in the coolest part of the room, and where the air
is never likely to be overheated, which is near the floor, where we
ourselves live and move. In the private libraries of our residences a
mistake is often made in carrying the shelving of our book-cases so high
that they enter the upper and overheated stratum of air.
