The defendants appeal from an order denying their motion for a new trial. They specify error of the court in excluding evidence as follows:
The action was for the price of goods sold and delivered. It appears that the case had been once before tried. At the second trial, from which this appeal originates, it appears that a witness (Coombs), who was one of the defendants, was absent. The stenographer who took the testimony on the first trial was called as a witness by plaintiffs to prove certain testimony given by Coombs on the former trial. The stenographer testified that Coombs had testified as to a certain letter written by himself to the plaintiffs, and which was in evidence on the former trial. The court allowed this testimony to be introduced. Upon its introduction the defendants desired to cross-examine. the stenographer, that he might state the testimony of Mr. Coombs given on the former trial as to the circumstances and facts in regard to the writing of the letter. This was excluded by the court, it appears, because the court held that it was not proper cross-examination. But see Territory v. Rehberg, 6 Mont. 471. The defendants thereupon made the stenographer their own witness, and then asked him, as their own witness, what the testimony of Coombs had been on the former trial as to the writing of this letter, which had already been introduced in evidence. The plaintiffs objected to this testimony on the ground that it was incompetent, immaterial, and irrelevant. The objection was sustained by the court. This the defendants assign as error. We are of opinion that it was error. Section 626, Code of Civil Procedure, 1887, is as follows :
‘ ‘ When part of an act, declaration, conversation, or writing is given in evidence by one party, the whole of the same subject may be inquired into by the other; when a letter is read, the answer may be given; and when a detached act, declaration, conversation, or writing is given in evidence, any other act, declaration, conversation, or writing which is necessary to make it understood, may also be given in evidence. ’ ’
We held in Kennelly v. Savage, ante, 119, that where, for *372the purpose of impeaching a witness, letters purporting to be written by him are introduced, it is both competent and material that he should be allowed to explain the circumstances under which and for which the letters were written. See, also, Territory v. Rehberg, 6 Mont. 471, 13 Pac. 132, and State v. Jackson, 9 Mont. 518, 24 Pac. 213.
For this reason the order denying a new trial must be reversed, and the case remanded, with instructions to grant a new trial.
The defendants also claim error in instruction No. 1, but they do not discuss such alleged error in their brief.
Reversed.
