Although there is a particular shade of carbon tissue on the market that for moonlight effects leaves little to be desired, it is not every worker who is prepared to turn out carbon prints, says Fayette J. Chuta in "Western Camera Notes."

The method by which they were produced it as follows: The bromide prints, which should be rather light, are toned to almost a bright red in a bath composed of
Uranium nitrate 40 gr.
Potassium ferricyanide 40 gr.
Acetic acid 2 dr.
Water 16 oz.
