be easily changed by removing the holders and fasteners. Corners

** Sleeve Holders for Lavatories [17]

A very handy article is an attachment on wash basins or lavatories
for holding the sleeves back while washing the hands. It is very
annoying to have the sleeves continually slip down and become wet
or soiled. The simple device shown herewith can be made with bent
wires or hooks and attached in such a way that it can be dropped
out

of the way when not in use.

** Removing Tarnish [17]

A pencil eraser will remove the tarnish from nickel plate, and the
ink eraser will remove the rust from drawing instruments.

** How to Make a Brass Bookmark [18]

Secure a piece of brass of No. 20 gauge, having a width of 2-1/4
in. and a length of 5 in. Make a design similar to that shown, the
head of which is 2 in. wide, the shaft 1 in. wide below the

[Illustration: FIG. 1 Fig. 2 The Pattern and the Finished
Bookmark]

head and the extreme length 4-1/2 in. Make one-half of the design,
as shown in Fig. 1, freehand, then trace the other half in the
usual way, after folding along the center line. Trace the design
on the metal, using carbon paper, which gives the outline of the
design Fig. 2.

With the metal shears, cut out the outline as indicated by the
drawing. With files, smooth off any roughness

[Illustration: Drilling and Sawing the Metal]

and form the edge so that it shall be nicely rounded.

The parts of the design in heavy color may be treated in several
ways. A very satisfactory treatment is obtained by etching, then
coloring. Clean the metal thoroughly with pumice stone and water
or with alcohol before the design is applied. Cover all the metal
that is not to be lowered with a thick coating of asphaltum. Allow
this to dry, then put on a second coat. After this has dried,
thoroughly immerse the metal in a solution composed as follows: 3
parts water, 1 part sulphuric acid, 1 part nitric acid.

Allow the metal to remain in this solution until the exposed part
has been eaten about 1/32 in. deep, then remove it and clean off
the asphaltum, using turpentine. Do not put the hands in the
solution, but use a swab on a stick.

For coloring olive green, use 2 parts water to 1 part permuriate
of iron. Apply with a small bru
