H- Baillie, manager of the Oregon state employment service in .Salem, said 6,000 pickers are needed immediately to save the bean crop, 50 per cent of which still remains on the vines. More 'than 8,000 pickers are already in the fields. About 3.000 workers it needed in the Independence area; 1,500 in the Stayton area; 1,000 around West Stayton and 500 around Sa lem. Hopyards as well as bean fields need workers. - Thi bean situation Is more cri tical this year than at any, time since the war," Baillie announced Monday. "Unless we get large numbers of volunteers immediate ly local growers and the valley as a whole will suffer a serious loss." Baillie said the picker shortage was due largely to a lack of mi gratory workers this summer. Transient workers this year num ber only about one-half of last year's force. , "It's up to the home folks this year," Baillie declared. "We in tend to talk with Mayor Robert JL, Eifstrom to see what can be worked out to save the crop." - Salem area residents may reg ister for bean picking at the em ployment service offices at Ferry and South Cottage streets at a. m. today and every day during the next three weeks. Pickers may also register and be transported to fields from offices in Stayton, Woodhurn and Independence. -. .
