Johns "Man"vtixe Corporation TYTTSTT -TWO mtT FORTIETH STREET NEW TORE 16, N.Y. January 10, 1951 Dr. W. J. McConnell Metropolitan Life Insurance Co. 1 Madison Avenue Hew York, N. I. Dear Dr. McConnells Re: Industrial Hygiene Survey Johns-Uanville Canadian Locations Ur. Lindell, our Mines Manager, has advised me that they have encountered some difficulty in maintaining negative pressure In the new dust shed and additional engineering modifications will have to be completed before it is functioning effectively. He has suggested that the Asbestos Mines'' survey be post poned until the week of February 26. Since we desire surveys to be made also at the Munro, Ontario Mine and the Asbestos Factory, the scheduling for these can be adjusted either before or after the Asbestos Mines1 survey in whatever manner will best suit your con venience . i would estimate that the survey at Munro and Asbestos Factory would take from tiro to three days each. Yours very truly. cc: Ur. J. Mm. Fehnel Metropolitan Life Insurance Co. 1 Madison Avenue New York, N. Y. 4
