Knives Placed in Such a Manner as to be Supported by the Three Glasses
A Scraper Handle
In using the ordinary steel-plate scraper, much inconvenience and cramping of the hands is experienced unless some suitable handle is attached. If a piece of scrap wood is taken and cut to a convenient shape, with a groove tightly fitting the scraper steel, greater pressure can be exerted and more effective work produced, without cramping the hands or tiring out the operator as readily.—Contributed by A.

Photographic Tray-Rocking Stand
Films develop better if the tray holding the solution is kept in motion or rocked. This is inconvenient and tiresome where a great many films are to be developed. The trouble may be overcome by the use of the rocking device shown in the sketch. It may be made of any light wood, the right size to suit the photographer's needs.
