During summer vacations, part of my school expense was earned as a purchaser of non-ferrous scrap metal for a small Chicago smelter. In such purchasing, it is very necessary to know something of the general composition of the metal. For example, in buying soldered articles, it is of vital importance to know whether the solder is high in tin or lead, and whether it contains antimony or bismuth. Other purchasers to whom I have talked have reported the same difficulty.
