MEDIATORS SEND HIM INVITA- TION TO PARTICIPATE IN
 PEACE NEGOTIATIONS.
NOTE IS NOT MADE PUBLIC
Conference With Carranza Has Be- Begun and on His Position May De pend the Success or Failure cf Peace Conference.

Washington, June 3 Whether the Mexican constitutionalists are to par ticipate in peace negotiations at Niagara Falls probably will be deter mined by tomorrow. Agents of Gen eral Carranza tonight were in tele- graphic communication with the con stitutionalist leader after having for warded to him the answer of the South American mediators to his message of protest carried to Niagara Falls last week.
 Publication of the mediators' mes sage was withheld here until General Carranza has determined on his reply Rafael Zubaran, minister of the in teror in Carranza's cabinet, and at the head of the constitutionalist agency in Washington, would not dis cuss the nature of the mediators' pro- posals or the probable attitude of his chief. Persons in touch with consti- tutionalist agents, however, suggest ed that the terms on which the me diators proposed to receive the con stitutionalists into the peace negotia- tions would be declined
 The mediators note, addressed to Mir, Zubaran. reached Washington in a special delivery letter. As soon as the message was received the consti- tutionalist agency began preparations to communicate with General Car ranza at Durango by a special wire. When the mediators' note had been forwarded conferences with their chieftains were begun over the wire, Mr Zubaran announcing that he hoped to have some conclusive infor- nation later in the evening. In that event it was considered probable there would be made public the medi- ators' message, together with an an swer if there was to be any, and also the original note from the cOnstitu- tionalists. It was said the mediators' message was accompanied by a re- quest that nothing be made public until a conclusion had been reached.
 Administration officials awaited the outcome with considerable anx- iety. Throughout the day there were some expressions of apprehension in official circles over the success of mediation plans as originally outlined. It was the first time that any admis- sions Ina dbeen made of probable set backs. Yet those who admitted the possibility of obstacles insisted that all difficulties ultimately would be overcome, Secretary Bryan again reiterated that mediation was pro gressng satisfactorily.
 At constitutionalist headquarters those engaged personally in the long distance deliberations with constitu- tionalist leaders flatly refused to say whether the communication con tained a possibility of settlement Of Mexican difficulties from the consu- tutionalst point of view. One source however intimated that there were suggestions in the note that had not been forecast in previous dispatches from Niagara Falls.
 While ammunition for the constitu- tionalists was en route today to Tam pico from the United States, admis- sion came from the state department of previously reported orders to GUS toms officials not to clear consiSn- ments of munitions of war to MeXi- can ports. Secretary Bryan said there seemed to have been some mis- construction of the original order.
 Assistant Secretary Roosevelt, act ing as secretary of the navy in the absence of Secretary Daniels, today said no orders had been given to the American naval commanders on the Mexican coast in regard to the treat ment of the steamship Antilla, laden with war supplies for the constitu- tionalists, when she appears in MeXi- can waters.
 This was taken as an answer to the question as to whether the American naval commanders would extend pro lection to the Antilla in the event that some of the Huerta gunboats which have been informed of the na- ture of her cargo should attempt 10 waylay the ship.
 The state department has taken TO action on the notification received today through American Consul Can bda at Vera Cruz that the constitu ltionalists at Tampico would refuse
