To Mark Toole

Tools may be marked with tetter punches in case they are not too hard. An excellent method Is by the use of nitric acid, which is easily procured at the drug stores and may be kept Indefinitely In a bottle having a glass stopper. The method is equally simple. Warm the tool to be marked enough to cause wax to adhere to It. In a thin film. Scratch the name with some sharp-pointed Instrument quite through the wax -A little nitric acid poured on the writing will quickly eat out the letters on the steel surface. Wash off the acid and, remove the wax with a hot rag. The job is done and tbe marking will be practically everlasting. '
