This is аn appeal by the United States from a judgment entered on the verdict of a jury awarding $121,500 as compensation for a 24.11 аcre tract of land in Springfield, Massachusetts, which was *800 condemned and taken by the United States for military purposes. The оnly question presented is whether the District Court erred in refusing to permit the government’s' expert witnesses on value to state оn direct examination what they believed or understood to be the prices paid at about the time of the taking for comparable lands in the area. More specifically, the District Court ruled “as a matter of law, and as a matter of discretion if not as of law,” that it would not allow the government’s experts to testify on direct examination as to the prices paid at about the time of the taking for other similar lands in the vicinity if their information was not based upon personal observation or participation in the particular transaction involved, but was based only upon talk on the street оr in the real estate trade, or recitations of consideration in, or computations from internal revenue stamps affixed to, deeds on file in the Registry.
The District Court clearly understood that its ruling conflicted with the holding of the Court of Appeаls for the Fourth Circuit in United States v. 5139.5 Acres of Land, etc., 1952,
We said in Baetjer v. United States, 1 Cir., 1944,
But the government contends that even though the testimony of its experts as to the prices paid for comparable lands in transactions as to which they had no firsthand knowledge was not admissible as substantive evidence to prove those prices, still they should have been allowed to testify as to those prices on direct examination to show the jury the basis *801 upon which their opinion of value rested. We do not agree.
It is true that the speciаlized knowledge of expert witnesses is usually derived in part, and may be derived wholly, from hearsay sources, such as statemеnts in text books and the instruction imparted by teachers and others in the particular field involved. But it does not follow from this that an expert witness may bolster his ultimate opinion of value by telling the jury what others told him. The principle was succinctly expressed by Mr. Justice Holmes when Chief Justice of the Supreme Judicial Court of Massachusetts in National Bank of Commerce v. City of Nеw Bedford, 1900,
We are loath to circumscribe a trial court’s discretion, however, by laying down a rule of law prohibiting an expert witness from еver giving the hearsay grounds upon which his opinion rests on direct examination. Perhaps there may be situations in which a trial court would think it helpful to permit a witness to give the basis, even if resting upon hearsay, for his opinion. We therefore sustain the ruling of the court below on the ground that no abuse of discretion is shown, rather than upon the accuracy of the ruling as a matter of law.
The judgment of the District Court is affirmed.
