The ruling of the court on admission of evidence was applied to questions intended to adduce from the witnesses the reasonable or market value of the rock in question. Defendants *147 objected to the form of the question because it did not take into consideration the expense of quarrying the rock and crushing it. Some of the remarks of the trial judge indicated that there had not been sufficient evidence of a market value for such material in that community to permit witnesses to testify as to the market value, but reading the entire record, including the colloquy between the court and the attorneys, we understand the ruling of the court to have been based upon the principle that the true measure of plaintiff’s damages under the circumstances was the value of the rock in place or the value of the rock after the same had been severed from the soil, less the expense of severing it. Under the circumstances we think the true measure to be not the value of the rock as it was ready for placing on the road but that value less the expense of preparing it for the road: 26 R. C. L. 1154, § 70; 1 Suth. Dam. (2 ed.), 216, 217; 40 C. J. 923, § 476 (6). The plaintiff did not propound the question to that effect. In order to preserve his objection plaintiff submitted in writing what he proposed to prove by said witnesses. His statement is as follows:

“Now on this 10th day of July, 1926, and the plaintiff putting on his case and after leave of the Court first had and obtained to make an offer of proof in writing and file the same in the record the plaintiff offers to prove by the witness, L. K. Porter that he the said L. K. Porter is a contractor of about seven years experience and knows the reasonable market value of rock in the quarry similar to the rock in the quarry in question and that the reasonable market value of such rock located as the quarry in question is located was worth in 1923 the sum of 25 cents per cu. yd. and that the rock in the quarry in question was of the reasonable value in the year 1923 *148 of 25 cents per cn. yd., which offer is refused by the Court and an exception allowed.

“The plaintiff further offers to prove by the witness C. P. Carlson that he has had twenty-five or thirty years experience in quarry work and rock values, that he now owns quarry no better and from which the rock is no better and no easier to remove than from the quarry in this action, that he has had said quarry leased for a period of seven consecutive years and that the same is now leased and that he knows the reasonable market value in 1923 of the rock in the quarry in question in this action and that said market value in 1923 was the sum of 25 cents per cu. yd., which offer was refused by the Court and an exception allowed.”

It will be seen from this written proposition that the proposal, was to show the value of the rock in the quarry. The question does not discriminate between the rock in place, and severed and crushed. In view of the fact that that was the objection made to the questions orally propounded to the witnesses and that the court ruled that the true measure of plaintiff’s damages would be the value of the rock in the quarry less the reasonable expense of severing it and crushing it, we think that the court did not err in refusing to permit the witnesses to answer the question. Plaintiff should have framed the questions so as to get at the true measure of the damages. Before plaintiff could be permitted to show the value of the rock other than the market value thereof, it would have been necessary for him to have shown that there was no market value: Swank v. Elwert, 55 Or. 487 (105 Pac. 901). The true measure of damages was the rock in the quarry severed and crushed, less the expense of severing and crushing it: 40 C. J. 923, § 476 (6). Plaintiff did not seek by his questions to employ that standard.

*149 Plaintiff also complains of some instructions given by the trial judge. His only assignment of error is the court’s refusal to give instructions requested by plaintiff and the modification of other instructions requested by plaintiff. This exception is hardly definite enough to enable this court to be certain regarding the particular instruction objected to. Nevertheless we have carefully examined the instructions and believe the court gave more liberal instructions in plaintiff’s favor in some respects than were requested by plaintiff and covered generally all of the instructions requested by plaintiff to which he was entitled. We find no reversible error in the record.

The judgment is affirmed. Affirmed.
