"It is not the policy of the law that it is better that one or any number of guilty men should escape rather than that an innocent person should suffer; the law has no policy in such matters except that every guilty man shall be punished. With all the information already in the possession of the law officers of the county at hand, it will be a blot on the commonwealth, a severe blow to the administration of justice, and a frightful menace to the safety of the individual citizen, if every man engaged in this shocking crime, or having guilty knowledge of it, shall not be discovered. "The whole power of the county is at your disposal. Employ your resources, use the power invested in you without fear or favor, and the result cannot be uncertain. You will now retire to the jury room and make your own arrangements for the transaction of the business for which you have been called together." At the conclusion of this address the grand jury retired, in charge of Bailiff Hamilton. An organization was quickly effected, and soon the twenty-three men were at work, with the assistance of State's Attorney Longenecker and his assistant, Jampolis. Acting Captain Schuettler was also called in, and from these officials the body received an outline of the case, very much from the same material which came before the coroner's jury, with the exception that the State's Attorney had prepared a connected narrative that, step by step, was to be corroborated by witnesses. At each of the stairways leading to the floor where the grand jury quarters were located bailiffs were stationed, and none but grand jurors and witnesses were permitted to pass. THE GRAND JURY'S INQUIRY. Beginning with the testimony of Mrs. Conklin, the liveryman Dinan, the furniture salesmen, and the agents of the Clark street flat, the Grand Jury traced the movements of the murderers, step by step. Daniel Brown, the police officer attached to the Stanton avenue station, and who had preferred the charges of treason against Dr. Cronin in a camp of the Clan-na-gael, was subjected to an exhaustive examination. He was kept on the stand for nearly two hours, and was not permitted to refuse to answer questions, or to avoid answering by saying that he did not recollect, or that he had forgotten. He was closely questioned concerning his connection with the order and his reasons for preferring the charge against the physician. [Illustration: OFFICER BROWN.]
