A gentleman of this city, Geo. Nimmo, has shown us some very good specimens of steel which he manufactures by a peculiar process from scrips of old wrought-iron and steel. Mr. Nimmo has prepared a flux which he uses in smelting the iron and steel which he says gives to the mixture the quality of good cast steele; this flux probably also imparts a : portion of its substance to the iron. The discovery may prove to be of value to manufac-turers as the process is very simple, and the ingredients used are not expensive. Tho dis-coverer,.Mr. Nimmo, has taken measures to secure a patent.
