one which makes tungsten mining on an ex- 

 tensive scale possible, is an alloy for tool steel. 

 Lathes using tools made from tungsten steel 

 may be speeded up until the chips leaving the 

 tool are so hot that they turn blue, an opera- 

 tion which would ruin the temper of high- 

 carbon steel. It is stated that about five times 

 as much can be done with lathes built for such 

 speed and work as can be done by the same 

 lathes with carbon-steel tools. From 16 to 20 

 per cent, of tungsten is ordinarily used in 

 lathe tools. The melting point of tungsten is 

 exceedingly high — 6,576° F. Tungsten also 

 has an important use in making incandes- 

 cent electric lamps, crucibles for electric 

 furnaces and various other articles.

 meetings in sections of the various associa-

 a general meeting of the afiiliated bodies to 

 hear lectures by distinguished exponents of 

 practical farming. Among the speakers en- 

 gaged for the week are James Wilson, secre- 

 tary of agriculture, and W. M. Hays, assistant 

 secretary of agriculture; Willis L. Moore,
