I Rod Hill operated 294 shifts and No. 2 Rod Mill operated 21 shifts daring 1950. The net rod production for the Bo. 1 Kill for the year was 136,4S3,051 pounds, and the gross production (including serap and scale) was 140.946.955 pounds. The net rod production for the Be. 2 Mill was 4.364.256 pounds, and the gross produc tion was 4.524.372 pounds. Ve produced 54.470.165 pounds of ox-off rods in 1950 as compared with a production of 30.612.950 pounds in 1949* A new record high production of 5/16" rods was set on March 22, when 1,724 bars were rolled for a total weight of 536.914 pounds, the previous record of 1,700 bars rolled, with a weight of 530,265 pounds, having been established Novenber 6, 1946. On March 23 the record was again broken when 1,770 bars were rolled for a total weight of 552,353 pounds* On June 21 a new record for nunber of bars rolled was established when 1,605 bars were rolled into 5/16" rods in an eight-hour shift.

This record was broken again on Deeenber 26, when 3,342 bars, weighing 1,042,527 pounds were rolled. In March the average daily production of 5/16" rods was also an all-time record, with 496,676 pounds per day, the previous pNYC 00012657 -3- high monthly record haring been established in December, 1946, with 493,493 pounds per day. In April the record was again broken by an arerage daily production of 503,517 pounds. In April a record was also established for the arerage production of 3/3" rods with 507,575 pounds per day, as compared to the prerious record of 431,014 pounds per day, established in December, 1949. In March a new record in arerage daily production of rods of all sises, on a one-shift basis, was set with an arerage pro duction of 434,635 pounds per shift, the prerious record haring been 476,560 pounds per day, established in November, 1949. It is particularly gratifying that these record produc tions were obtained without impairment of quality of finished product. One wire drawing machine was equipped for drawing aluminum wire from purchased rods, and started production during the last half of the year. The production of wire, including wire made into strand, was 3,441,334 pounds. This includes 537,404 pounds of aluminum wire. There was also produced during the year 209,633 pounds of drawn rods, 6,943 pounds of twisted flat wire, and 7,203 pounds of flat wire, making a total wire and drawn rod production of 3,665,623 pounds.

During the season 2,266 members registered for play and there were 449 card guests and 143 guests by fee. The average registration for the season was 571 per month. PNYC 00012659 -10- Forty bowling teams participated in the regular weekly schedule during the 1949-50 season, bowling at "Little's Lanes" in the city of Great Falls during the first four months of the year and at the new Employees Clubhouse during the months of October to December. The games bowled during the months of January - April, 1950, totaled 8,400. After the opedihg: of the new clubhouse bowling alleys in October, 1950, a total of 88 men's teams and 16 women's teams participated in league play and during that time bowled 22,149 games. The new Employees Club was formally opened December 17, 1950, with an "open house" to which all employees, their families and the general public were invited. Approximately 2,000 attended the opening. . A Christmas smoker held immediately after the opening of the Employees Club was attended by 837 men. The total maturity value of bonds purchased by employees of the Great Falls Reduction Department through payroll purchase plan from January 1, 1950 to January 1, 1951, amounted to 158,900 and the total maturity value of bonds purchased by Great Falls employees of the Anaconda Wire and Cable Company amounted to $1,725 For the same period, giving a total of $60,625 in bonds purchased through Company facilities by the Great Falls employees. The total maturity value of bonds purchased by employees at the East Helena Slag Treat ment Plant during the year amounted to $850. PNYC 00012660 -11 Safety and First Aid Activities He regret to record that there were four accidental deaths from arsine gas poisoning in the Great Falls Seduction Department in 1950. Thirteen departments went through the entire year with out a lost-time injury of any kind. The accident rate for the year was 2.14 total accidents in 1950 against 2.20 in 1949. based on 10,000 shifts worked. The serious accident rate was 0.95 per 10,000 shifts worked as compared with 0.94 in 1949* The tQtal number of accidents for the year amounted to 112, compared with 117 in 1949. ' Safety Meetings were held in the various operating depart ments at regular intervals throughout the year. Many worthwhile suggestions for improvement of working conditions and safety were brought up at these meetings. Several new procedures were started in an effort to arouse interest in'safety on the part of the in dividual employees, notably a system of awards for safety sug gestions. The excellent suggestions entered in this competition seem to justify continuation of this program through 1951* Regular weekly trips were made by the Safety and Welfare Engineer to the city hospitals to visit the sick and injured em ployees. There were 3,542 employee visits to the First Aid stations for treatment of original injuries and 167 visits for treatment of illness. Labor During the year 1950 we hired $17 employees and had 942 separations, leaving a net loss of 125 employees. PNYC 00012661 -12- Negotiations with the Unions for new contracts were held in the spring of 1950 and new contracts, effective July 1, 1950, were signed, granting wage increases of 51 per hour, plus sobs added benefits. Further negotiations were carried on in the fall and an additional wage increase of 101 per hour was granted, effective October 16, 1950. - During the first quarter of 1950 6% of our eaployees who are members of the Mill and Snelteraen's Union were scheduled to work on a 6-day basis. During the second quarter this figure dropped to 2In the third quarter it increased to 6% and in the fourth quarter it increased to 49S&.
