To the Editor of the "Norm Cro Day News"
Sm—In reply to Or" Suors enquiry about removal of stains from Old brown leather shoes, I would recommend the following preparation:
Pour carbon bisulphide on non-vulcanized gutta-percha, and allow it to stand about 24 hours. After shaking actively add more gutta-percha gradually, until the solution becomes Of gelatinous consistency. This mix lure is applied in suitable quantity io oil-stained, coloured, leather and allowed to dry, two or three boni The subsequent operation consists merely in removing the coat of gutta-percha from the surface of the leather—that is, rubbing it with the fingers, and rolling it off the surface. The colour is not injured in the least by the sulphuret of carbon—only those leathers on which a dressing containing starch has been used, look a little lighter in colour, but the better class of leathers are not so, dressed. The dry gutta-percha can re-dissolved in sulphuret of carbon and, used over again.
