William C. Durant, President of Durant Motors, Inc., who was largely responsible for the organization of the General Motors Corporation, is described in reports circulated in Wall Street yesterday as the moving spirit in a plan for a new automobile combination, with a capitalization that may exceed $100,000,000 and that may bring together companies including Moon Motor, Chandler Motor, Gardner Motor, Hupmobile, Jordan Motor, Peerless Motor and Star Motor.

Mr. Durant was out of the city yesterday and no one could be reached at his office who would discuss the report. Moritz Rosenthal, a member of the Stock Exchange firm of Ladenburg, Thalmann & Co. and a director of the Hupp Motor Car Corporation, said he had not taken part in any discussions for such a merger.

The Hupp Company, according to the reports, is to be the nucleus of the combination. Besides the other companies mentioned the merger plan calls for the inclusion of at least three accessory enterprises. Representatives of axle, transmission and body building companies are said to have taken part in the conferences here. The Moon, Chandler, Gardner, Hupmobile, Jordan, Peerless and Star organizations were represented in the conferences here, it was reported.

Mr. Durant controls the Durant Company. He announced some time ago that he intended to make that company the keystone in a large automobile enterprise that would take front rank in the industry. Details of his plan have never been disclosed.

The consolidation, if carried out, would involve no new financing, it was said, but the transaction would be carried out through an exchange of securities.
