May Be Appointed to Succeed Pinchot— Other Matters. Washington, Jan. 11.—In casting about for a successor to Gifford Pin chot to head the forestry service, it was reported today that President Taft might offer the place to Seth Bullock, United States marshal for South Dako ta. At the present time,Albert F. Potter, designated as the acting head of the service, seems to be the leading candidate, but there are persistent rumors that the president may decide that an entirely new man might better reorganize the service. Mr. Bullock is in many respects as close a friend of former President Roosevelt as is Mr. Pinchot. He was once chief of the forest ranges in the Black Hills,and is thoroughly familiar with the whole subject of forestry. The political situation in South Dakota has been giving the president some concern of late, and Senators Crawford and Gamble have been fre quent callers at the white house. Bullock has been designated for reap pointment for United States marshal of South Dakota. His term expires this month.
