Opinion by
Porter, J.,The defendant company having become interested in an option to purchase certain lands, desired to obtain definite information, before the option expired, as to whether the land was underlaid with coal and, if so underlaid, the thickness and quality of the stratum. They entered into a contract with the plaintiff company to explore the land with a diamond drill, the drilling to be done at such points as the defendant company should indicate, and the work to be paid for at the rate of 12.00 per foot. The work has all been paid for except the last well, 'which was drilled upon a part of the property known as the Noel Farm, for which the defendant company refuses to pay. The plaintiffs brought this action to recover for the drilling of *617the last well, alleging in their statement: “ That the defendant employed the plaintiff to put down a diamond drill hole on certain lands in Cambria county, for the purpose of investigating the strata underlying the surface at the point indicated by the defendant; that it was agreed by and between the parties that the defendant should pay the sum of $2.00 per foot for whatever depth it was necessary to drill said well at the point indicated; that in pursuance of said agreement the plaintiff entered upon the premises indicated by the defendant, and put down said hole in accordance with the terms of said contract, a depth of 485 J feet, and completed the same on or about June 1, 1903.” The plaintiffs filed' an affidavit of defense, a plea of non assumpsit was entered and upon that issue the case went to trial. The learned judge of the court below gave binding instructions in favor of the defendant company, and the plaintiffs appeal.
There was no dispute, under the evidence, as to the facts material to the right of the plaintiffs to recover. They had alleged in their statement that the contract was entered into and the work done “ for the purpose of investigating the strata underlying the surface at the point indicated by the defendant,” and the evidence clearly established that such was the only object of the parties. C. C. Hoover, the active partner and manager of the plaintiff firm, testified that the purpose of the drilling was to determine the formations of the earth and ascertain the thickness of the coal measures in the property ; that the way in which this is accomplished and the strata through which you pass with a diamond drill shown is by bringing out a core of the strata; as the drill progressed downward a core of the strata passed into the core barrel and was therein brought to the surface and removed ; the core brought out by the drill used in this operation was two and one-quarter inches in diameter. Tins testimony is in absolute harmony with all the other evidence in the case and clearly establishes that the understanding of the parties was that the practical purpose, aim and design of this contract was that the work done under it should result in furnishing to the defendant company a core consisting of a column extending down through the formations of the earth and representing the actual stratification. Such a core would not only have informed the defendants as to the position and *618thickness of the coal stratum, but would have enabled them to obtain accurate knowledge of the quality and value of the coal.
The plaintiffs employed one White and delegated to him the execution of the work and performance of all the duties which they had assumed under the contract. When the coal stratum was passed through the drill brought up a core twenty-two inches in length; White added to this a sufficient amount of coal core taken from a hole on some other property to make a core three feet in length, thus giving it the appearance of a core actually taken from one stratum of coal three feet in thickness; and at the same time entered upon the record of the well kept by him a statement that the drill had passed through a stratum of coal three feet in thickness. He placed this fabricated core in a core box, a device intended to keep the core in the position in which it was taken from the well, and delivered it to the defendant company as the core actually taken from this hole. The drilling was continued for some days after this, when, one of White’s assistants having failed to keep the secret, the defendant company acquired knowledge of the fraud, notified plaintiffs to stop the drill and refused to pay for the work.
The burden was upon the plaintiffs to prove performance of their contract; they had not performed in any other manner than through White and were for his acts responsible. Where one of two innocent persons must suffer by the fraud or negligence of a third, whichever of the two has accredited him, ought to bear the loss: Mundorff v. Wickersham, 63 Pa. 87. The defendants had not agreed to merely have a hole drilled in their land, they had agreed to pay for what a properly and honestly operated diamond drill would take out of the hole. The action of the agent of the plaintiffs in fabricating a false core and thus destroying the identity of the true core taken from the stratum in question not only deprived the defendant company of the reliable information which it was entitled to have, but it tended affirmatively to mislead them. Such an execution of the work was in no sense a substantial performance of the contract, but a fraudulent, defective and worthless performance, the same as no performance at all: Miller v. Phillips, 31 Pa. 218; Hartman v. Meighan, 171 Pa. 46; Gil*619lespie Tool Co. v. Wilson, 123 Pa. 19. One who agrees to pay for the information resulting from an honest investigation cannot be called upon to pay for an intentionally false and deceptive report.
The judgment is affirmed.
