Chicago, Sept. 8.- The third week oí the Luetgert murder trial was begun before Judge Tuthill Tuesday morning. It was the beginning of the second week of the taking of testimony, the first week having been devoted to securing the jury, and it is believed by the attorneys for the state that it will tak uptil after Sept. 15 before all the witnesses for the prosecution have been tieard from. . It was said last Saturday by Assista.nt States Attorney McEwen that he would probably be through with his side of th case by next Saturday, but that official now says that he believes the expert testimony to be introduced will take up so much time that the state will not be ready to close its side of the case until some time next week. This being the situaticn, It is believed it will be Oct. 1 before the jury will go out to determine the fate of the prisoner. Wore a Satisfied Sinile. Luetgert, when he came into court Tuesday, was the same unconcerned individual he has appeared to be during the trial. As usual he carried the stump of a cigar and he puffed away at it contentedly while looking over the morning papers until court convened. He greeted all his friends as cordially as usual and there was a satisfied smile on his face as he took his seat. Mr. McEwen announced at the opening of court that he would read the English translation of the letters Luetgert wrote to Mrs. Feldt. Mr. "Vincent objected, claiming that the translations were not exact reproductions. The defendant's attorney also said he wanted all the letters written by Luetgert to the widow introduced. The objections were overruled and Mr. McEwen proceeded to read to the jury. He read in a loud tone of voice, and the words "beloved. dear Christine" and other endearing terms were heard in all parts of the court room. Luetgert sat tilted back in hip chair and teetered forward and r-uring the reading. He pmiled freqif-tly as? some thrust at the pólice wa? 'entioned, but no nervousness or irritability was made evident by. the man during the long time consumed In reading the six letters.
