Cyanide of potassium ....... 2 oz. 
Iodide of potassium ....... 20 gr. 
Water ..................... 16 oz.

Place the dry print, without previous wetting, in this solution.  It will bleach slowly and evenly, but, when it starts to bleach, transfer it to a tray of water, where it will continue to bleach.  When the desired reduction has taken place, stop the action at once by immersing the print in a 10-per-cent solution of borax.  The prints may be allowed to remain in this last solution until they are finished.  A good final washing completes the process.  This washing must be thorough and a sponge or a tuft of cotton used to clean the surface of the print.

With a little practice, this method of saving prints that are too dark becomes easy and certain.  The prints are lightened and at the same time improved in tone, being made blue-black with a delicate and pleasing quality that will tempt you to purposely overexpose some of your prints in order to tone them by this method for certain effects.  The process is particularly valuable to the worker in large sizes, as it provides a means of making quite a saving of paper that would otherwise be thrown away.

** An Ironing-Board Stand [17]

An ordinary ironing board is cut square on the large end and a slot cut 1-1/2 in. wide and 4 in. long to admit the angle support.  The support is placed against the table and the board

** A Desk Blotting Pad [17]

Procure four sheets of blotting paper, preferably the colored kind, as it will appear clean much longer than the white.  The size of the pad depends on the size of the blotting paper.

Fold four pieces of ordinary wrapping paper, 5 by 15 in. in size, three times, to make it 5 by 5 in.  Fold each one from corner to corner as shown in Fig. 1 and again as in Fig. 2.  Paste the last fold together and the corner holders are complete.  Put one on each corner of the blotting paper.  They can be fastened with a small brass paper fastener put through the top of the holder.  The blotting paper can

be easily changed by removing the holders and fasteners.  Corners complete are shown in Fig. 3.  —­Contributed by J. Wilson Aldred Toronto, Canada.

** 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
