are very
hard to get rid of. Make it a special point to clean the window once a
week, put in different stock every time, and do not be afraid to display
goods because the dust will spoil them. If the article in question is
delicate and easily ruined, leave it in the window only a few days;
display samples of the latest goods, and, if necessary, buy some article
that is showy, and which you think will attract people, especially for the
window, even though the amount expended is "sunk." It will certainly pay
in the end. If your stock of a certain article or class of goods is large,
devote the whole window to it for a week.

It is impossible to give rules for the arrangement, which, of course,
depends on the goods to be shown and the taste of the person dressing the
window. Stamped papers and visiting cards can be shown effectively in the
following manner:--Have a number of wooden blocks made the size of a
quarter of a ream of paper and a package of visiting cards; wrap these
neatly with a sample sheet of paper or cards on the outside, tied with
ribbon. Another way to show printed visiting cards is to make a small
pyramid of them by taking three small square boxes of different sizes,
which, when placed one on top of the other, will form a small pyramid.
Cover these entirely with samples of visiting cards, and place in the
center of the window.

PHOTO-LITHOGRAPHIC TRANSFER PAPER.

Photo-lithographic transfer paper and ink are prepared in the following
manner:--The paper is treated with a solution of a hundred parts of
gelatine and one part of chrome alum in 2,400 parts of water. After
drying, it is treated with the white of egg. It is made sensitive with a
bath consisting of one part of chrome alum, 14 parts of water and 4 parts
of alcohol. The latter ingredient prevents the white of egg from
dissolving. On the dark places the white of egg, together with the ink
with which the exposed paper has been coated, separates in water. The
transfer ink consists of 20 parts of printing ink, 50 parts of wax, 40
parts of tallow, 35 parts of colophony, 210 parts of oil of turpentine, 30
parts of Berlin blue. It is found that a varnish formed of Canadian
balsam, dissolved in turpentine, supplies a most valuable means of making
paper transparent. The mode by which this is most satisfactorily
accomplished is by applying a thin coating of this varnish to the paper,
so as to permeate it thoroughly, after which it is to be coated on both
