Wolter E.D. Lovick - Libby PERSONAL S CONFIDENTIAL During my visit last week, Earl Lovick and I made a brief summary of the results of our annual chest X-Ray screening. We hope that this will give us a rough barometer to gauge our progress in controlling fibrosis at Libby. The results are distressing but there may be an indication that we have reached the peak. Specifically, the number of employees with five years service who have problems is declining. I hope that this trend will be reflected in those with over 10 years service in the future. Earl will provide a summary of 1975 results shortly.
