New York, Sept. II (By the A P).- The exact cause of the explosion which in the twinkling of an eye yesterday noon transformed Wall street near Broad from a scene of bustling activity to one of dreadful carnage remains tonight mys- tery.
 Official opinion, as expressed by Wil- liam J. Flynn, chief of the bureau ot ln- vestigation of the department of justice, and Fire Commissioner Thomas Brennan, is that the disaster was caused by time bomb loaded with high explosives and re- inforced with metal slugs. The early theory that the blast was caused by collision between an explosive laden wagon and another vehicle seems to have been dispeled by subsequent investiga- tion. although it has not yet been entlre- ly discarded by official investigators.
 Chief Flynn, who arrived here from Washington last night to take personal charge of the federal investigation, de- clared after leaving the J. P. Morgan office late today that from evidence ob- tained within the last few hours it has been definitely estat lished that the explo- sion was due to a time bomb"
 ''The bomb was taken to Wall street. he added "in the wagon which was blown to pieces. The inferral machine was timed to go off at noon and apparently was placed in the wagon by a person who was within four blocks of Wall and Broad streets when the explosion occurred"
 Six more deaths since midnight brought the death tota Tonight to 35. The num- ber of injured. including those treated at the scene, in hospitals and at their homes, was approximately 300. Nearly l00 ot these are still being treated in hospitals. e mated at from s1 1,0c0,000 to $2,50O,OOn.
 Eight separate investigations of tEe ex- plosion were under way tonight They were being made by the department oi 3ustice. under the supervision of Attorney General Palmer and William J. Flynn chief of the bureau of investigation the New York police department. under the supervision of Commissioner Enright ant Chief Inspector Lahey; the fire depart nent. the building department, the Sep tember grand jury, the medical exam iners office and two private inquiries b1 insurance companies and J. P. Morgan Go.
 The key to the mystery apparent! lies in the identification of the rlcketJ olC wagon drawn by an old horse which wa! left standing at the curb in Wall stree nea rthe United States assay office an6
  a few minutes before the explosion I'm horse was killed and the wagon blown t hits in the blast. The driver of tn wagon is believed to have escaped. Fed erat and police authorities tonight wer centering their activities on this phase 0 the case.
 Every livery stable in the city is bein canvassed to determine whether hors and truck are missing. Examination o the horses body disclosed that it ha been newly clipped and shod. This am a mark on the horses shoes furnish tn only clues to it's identity.
 Conflicting descriptions of the waGo itself have been received by the police All available bits of the vehicle hay been taken 10 police headquarters, wher efforts are being made to reconstruct tn vehicle sufficiently to determine it's exac tyne. 4 cursory examination indicates was of unusual breadth, which leads De tective Chief Coughlin to believe it wa of the type used in transporting crates c eggs Official opinion is almost unan nous that it was not the regular typ wagon used in the transportation of pow der or explosives through city streets.
