VANADIUM IN STEEL
\7ANADIUM, first discovered in 1801, * is a mineral which in late years has been applied with remarkable results in the steel industry. The reason it was not used sooner in the manufacturing arts was because of its scarcity. Large and exceptionally rich deposits of vanadium ores were discovered in the Peruvian Andes several years ago. It is to this source that vanadium steels hold their present commercial status.
Scientists in the employ of the French government first settled the question, "Does vanadium improve the quality of steel?" They proved that the addition of a small percentage of vanadium— never above three-quarters of one per cent—gives to steel a remarkable increase in strength without impairing its
ductility—a result that cannot be secured from any other element used in the composition of steel. Carbon, for example, increases the strength up to a certain point but causes brittleness, and even fails to strengthen when employed in large amounts, the result of further additions producing ordinary pig iron.
Pittsburg manufacturers who have used vanadium in their steel products report extraordinary results. It is claimed that a two years' test of vanadium against ordinary steel shows an actual saving of $761.59 on a single item—a flue cutter weighing three ounces. In one year, 1,049 carbon steel cutters were used to cut 145,444 flues. In the next year 60 vanadium steel cutters cut 152,578 flues. The average number of tubes cut with the carbon steel tool was 139; the average for the vanadium steel, 2.244. The cost of the carbon steel cutter per hundred flues was $.54 compared with one and six-tenths cents per hundred, with the vanadium steel tool.

IT is usually the labor of years to get a few representatives for a piano, because piano dealers cannot be talked into changing their lines. They have connections running back in many cases almost a lifetime. So when the New Scale Lyon & Healy Piano was placed on the market it was said that if it were taken on by forty or fifty dealers in two years it would be doing very well. But 238 dealers, which is to say
238 Judges of Pianos
secured the agency in less than two years. Nothing approaching this record has ever been made in the history of the piano trade. Two hundred and thirty-eight dealers, in two hundred and thirtyeight cities and towns, when one-fifth that number would have been considered a success!
The Lyon & Healy Piano is pure in tone; it bears a world-known name; and it it sold from $350 up. There is nothing like it. Be sure to see it and hear it before deciding. Beautiful analytical catalog free. Write today.
