To make a boot size that will give a brilliant polish as seen in factory made split kip uppers, boil some cheap glue, broken up very line (or it may be dissolved in a glue pot), to prevent it burning; it should be quite thin, but not watery. Then boil some soap, and when both the glue and soap are well dissolved, add the latter to the former, well stir, put in a few drops of ammonia, and strain through muslin. If, when cold, the substance is thicker than cream, warm up again with more water. If it is old stock that is to be revived, logwood chips can be boiled with the soap.
