The exclusion of the confession made to Vanston on the night of the arrest was correct. Commonwealth v. Nott, 135 Mass. 269. Commonwealth v. Preece, 140 Mass. 276. The point now is whether the questions to the defendant by the *532same officer, and the defendant’s answers thereto the next day in the district court, as testified to by a witness who heard them, were rightly admitted. It may be fairly assumed that the defendant was, to some extent at least, induced to answer as he did by Vanston’s knowledge derived from what he had himself told him. But the question is whether the answers were voluntary, or were made under the influence of what the officer had told him the night before when he said to him that he had better tell the truth. At the time of making the answers the defendant had been arraigned, and was in open court. It does not appear at what time of night he was arrested, or at what time of day he was arraigned. But a number of hours had passed since the remark of the officer, and he had had abundant opportunity for reflection and consideration. When asked if he was guilty or not guilty, instead of answering directly, he said voluntarily that “ he did not know anything about the whiffletrees.” Thereupon, in the presence of the justice, and without objection from him, the officer asked the questions, and the defendant made the answers, which were testified to. No inducement was then held out to him. He was not obliged to answer if he did not choose to. He could have applied to the court, if he had seen fit, for protection. He did not do so. He appears to have answered the questions freely, voluntarily, and truthfully, and so far as the evidence discloses without relying upon or even remembering the words of the officer the night before. Confessions are not to be excluded because they are the admissions of a person charged with the commission of a crime, but only where the circumstances are such under which they are made that a reasonable presumption arises that they may have been induced by a promise or threat from one in authority, and consequently are open to the objection that they may not be true. Commonwealth v. Sego, 125 Mass. 210, 213. Commonwealth v. Preece, ubi supra. There are many cases in which confessions made originally under the influence of a promise or threat, and then repeated, have been excluded, because of the presumption that, under the circumstances of the case, the party in making them was influenced by the original promise or threat. There are also many cases where such confessions have been admitted on the ground that there was no reasonable pre*533sumption that the threat or promise operated to induce them. It would serve no useful purpose to attempt to review, or consider, or reconcile all of these cases, if that were possible. For a collection of them, see 3 Am. & Eng. Encyc. of Law, 439 et seq. We think that this case comes within the latter class, and that the circumstances were not such as to afford a reasonable presumption that the defendant’s answers were influenced by the remark made to him by Vanston, and that therefore they must be regarded as made voluntarily. If they had been made to another officer, we presume no question would have been raised as to their admissibility. We do not think that, under the circumstances, the fact that they were made to the same officer to whom the original confession was made, and who then held out the inducement, renders them incompetent.
