FRARY D IR E C T O R July 24, 1944< Dr. Leroy 0. Gardner The Saranac Laboratory Saranac Lake, 8. Y. Dear Dr. Gardner:1 Dr. Irwin and I have discussed your letter of July 20 and agree that it will not he necessary to sake any further tests on the silica fume from Badin. Dr. Irwin will discuss this matter with you when he is in Saranac Lake this week. V/e are planning to have some air-borne samples collected by the electrostatic precipitator, as you suggest, but have so far been unable to obtain the precipitator. The clumping of the particles in the sample sent you is to be expected because this sample was collected in the hood over the furnace rather than from the smoke in the stack. Yours very truly, Direct Aluminum Research Laboratories ALUMINUM COMPANY OF AMERICA
