'DYNAMITING INVESTIGATION
OSCAR LAWLER GOES TO WASH INcToN TO CONFER WITH THE
 PRESIDENT.
Principal Witnesses In Celebrated Case Now Being Assembled at ln- dianapols to be Guarded on
 Federal Ground.

Indianapolis, Ind, Jan. 5.-Oscar Lawler, special assistant to Attorney General Wickersham in the govern ments prosecution of the alleged dyn- amiting conspiracy, left here tonight for Washington, D C., after a three day conference with United States Attorney Charles w. Miller, in charge of the federal investigation in this district.
 MT. Lawler probably wall confer with President Taft, as we'll as the attorney general on the latter's re turn from Panama next weeN. Be sides being able to give the president @ personal account of what the in- yestigation revealed at Los Angeles MT. Lawler now can furnish gen eral resume of all the evidence gath cred here and also showing where throughout the country, there have been alleged violations of federal laws in transporting explosives and coaspiracies to violate these laws. He will have with him states At torney John D. Fredericks of Los An geles County, California, prosecutor of the McNamaras, who left here ear Her today for Washington.
 It will be the first opportunity Mir. Lawler viii have had to talk with President Taft about tine dynamiting conspiracy, since October 16, a few days after the McNamara trial began, when the president was on a speak ing tour in California At that time, MT. Lawler impressed upon the pres ident, not only that the MeNamaras were guilty but that violations of the federal statutes had been general in connection with numerous explosions from coast to coast in the last three years. The governments Investigation thereupon was ordered by the presi- dent to begin immediately at Indian apolls, but to be taken up in Call fornia, only after the McNamara trial was concluded by the state authori- ties.
 MT. Lawler took with him many important books and papers which he will exhibit personally to officials to department of justice.
 Many of McManlgal's confessions have never reached the department as it was not believed advisable to transmit them by mail because of the many persons through whose hands they might pass before reaching the proper officials.
 Lawler Will return here some time next week, in time to assist in the examination of Ortie McMa.aigal, con fessed dynamiter, before the federal grand jury.
 McManigal, who now is enroute, is expected to reach here on Sunday 
 Admittedly the government most important witness McManigal is ex- pected to relate in minHtest detail the story of his two years experience in dynamiting at the direction of John !. McNamara, secretary of the In- ternational Association of Bridge and Structural Iron Workers; and to tell with whom he was associated in causing explosions.
 It was learned today that prepara. tions to guard McManigal in the fed eral building have resulted, not only from the desire to protect him from possible enemies, but to prevent any interference from the county author Fities. He, therefore, will be kept on federal territory instead of at the county jail, where county officers could interrogate him or possible ar rest him for alleged state offenses as he is not under federal indictment, but Is subject to a subpoenae in this jurisdiction.
 This Is an echo of the friction be tween County Prosecutor Frfnk P. Baker and the California authorities over the removal of evidence to the coast.
 From the time McManigal arrives until his departure, he will be in the custody of Deputy Unted States mar shals.
 Three important witnesses appear ed at the federal grand jury cham Der today They were Patrick J Dugan formerly business agent. o'
