Within a few months he was in Korea. and. after a struggle against what seemed an insurmountable mountain of red tape. he tunneled through and returned to America with 12 orphans in tow. 8 of them destined to become full and equal members of Mr. Holts happy family. So heartening was the Holt story. that it brought appeals from 1.000 additional American families willing to make homes for orphans. Mr. Holt left his plow and began the enormous task of shepherding the hundreds of remaining halfcaste children across the North Pacific before the termination of the Refugee Act December 31. Last Saturday he arrived with his first contingent of 12. to be sent on to fbster parents in the East and Midwest. He hopes to have found homes for several hundred more by years end. for all of the KoreanAmerican waifs if possible.
