Zimmer had testified before the Grand Jury that at the direction of Mr. Glass, he had drawn large sums in currency from the banks, and given the money to Halsey. Halsey[287] gave no vouchers for this money which he received from Zimmer. The amounts were accounted for at the company's office by tags in the cash drawer. The testimony which Zimmer had given before the Grand Jury connected Glass directly with the large amounts which Halsey, without giving vouchers, had received from the telephone company's treasury at the time of the bribery transactions. The prosecution depended upon Zimmer's testimony to solidify their case. But when Zimmer was called to the stand, he refused to testify. Zimmer based his refusal upon the ground that in his opinion the Grand Jury had indicted a number of gentlemen upon evidence which Mr. Zimmer regarded as insufficient, and that he would not, to protect his own interests, testify.[288] The court instructed Mr. Zimmer that his position was untenable. The witness continued obdurate. The court sentenced him to serve five days in the county jail for contempt. After his five-days' term had expired, Zimmer was again called to the stand, and again did he refuse to testify; again was he sentenced to serve in the county jail, this time for one day. Upon the expiration of this second sentence, Zimmer was for the third time called to the stand, for the third time refused to testify. For the third time was he adjudged guilty of contempt. His third sentence was to serve five days in the county jail and pay a fine of $500. Before he had served his time, the Glass trial had been concluded. Zimmer, therefore, escaped testifying against his associate, Glass. But for his refusal, he served eleven days in the county jail and paid a fine of $500. The maximum penalty for the crime of bribery alleged against Glass was fourteen years penal servitude. Mr. Zimmer thus served fewer days than Mr. Glass might have been sentenced to serve years had he been convicted. The testimony which Zimmer[289] gave before the Grand Jury, was not presented to the trial jury. Nevertheless, the prosecution considered that it had made out a strong case, but Mr. Heney and his associates had reckoned without D. M. Delmas, Glass's chief counsel. The defense introduced no evidence, but Delmas, in a masterful argument, raised the question of reasonable doubt. He insisted that Glass had not necessarily given the money to Halsey. He argued that several others of the officials of the company could have authorized the transaction. By an elaborate chain of reasoning, for example, Delmas insisted that if the money had been given Halsey at all, President Henry T. Scott[290] could have provided for it.
