Washington, Sept. 25--President Roosevelt today began reorganization of the National Recovery Administration by accepting the resignation of Gen. Hugh S. Johnson as administrator.

Johnson took office on June 16, 1933, when the National Industrial Recovery Act became effective. Internal dissension and dispute within the past eight months slowed the pace of the once fast moving organization until today it is a center of uncertainty and confusion.

Miss Frances Robinson, $6,000-a-year adviser to Johnson and a deputy administrator, probably will pass from the N R A picture with him. Many persons believe the initials "N R A" themselves will disappear in the reorganization process now formally under way.
