The important question involved, and the one decisive of all the errors discussed, is the proper construction of the written obligations. The plaintiff in various forms asked the court to instruct that it was the duty of the defendant under the contract to sink the shaft to the lowest depth at which it would be practical to operate a four foot vein of merchantable coal, unless the evidence shows affirmatively that the defendant at such depth would not have found a four foot vein of coal. The court refused all the instructions asked, and instructed the jury as follows:
“ 1. Uhder the contract in question in this case, if you find said note was. given as part consideration for the purchase of the eighty acres on which said shaft was located, and that the defendant was engaged in sinking a shaft on said land at the time under the lease in evidence in this case, then, under this contract the defendant would, be bound to make-a reasonable effort to find coal of the character described in the contract, and if he neglected so to do, then he would be liable under the contract for said money.
“ 2. But under said contract he would not be under an obligation to sink said shaft to an extraordinary depth, but he would only be required to sink it to the ordinary depth at which such coal was found, in view of the known depth of the coal veins at the time he was engaged in sinking said shaft, using the ordinary and usual means and appliances in so doing, and such expenditure of money in so doing as was usual, ordinary and reasonable, in view of the knowledge then existing of the coal veins in the country; and if you find that the defendant has so done, and a vein of coal of the depth*625 and character not found, then the defendant is not liable; that is to say, unless the defendant actually reached with the shaft a vein of coal of the depth and character provided by the contract, he would not be liable, unless he failed to make a reasonable effort so to do, as before defined.
“ 3. The defendant is not bound to experiment and see if coal could be found at a depth beyond which such coal could be reasonably expected to be found.
“ 4. In determining whether or not the defendant sunk the shaft to a reasonable depth, you should consider the depth of other shafts and coal of the character described by the contract in the country, and the depth of the shaft sunk, the cost and expense of sinking the same, and the expenditure actually made in so doing, and the information and knowledge then existing with reference to the veins below the surface in this part of the country, and the difficulty and cost of operating said shaft.
“ 5. The fact that, since the shaft has been abandoned, coal has been found at another point on said land cannot be considered in determining whether or not defendant made a reasonable effort.
“6. Defendant was not necessarily bound to sink said shaft to the lowest depth that it would pay to operate a coal mine; he was simply required to sink said shaft to a reasonable depth, taking into consideration the depth at which such vein of coal has been found in other coal shafts- in the same neighborhood at that time, and other facts, as before stated.”
The plaintiff excepted to all of these instructions, and assigns the giving of them as error. We think they place a proper construction upon the contract, and announce correct rules of law. The defendant might have been under obligation to sink the shaft to the lowest practicable depth, if he had been certain of finding the requisite vein of coal at that depth. But there is no rule of law which requires him to hazard his money to such an extent.upon an uncertainty. All that the law requires is that he shall act in good faith, and
II. The plaintiff assigns as error the refusal of the court to give the following instruction: If, at the time defendant abandoned the farther search for coal in said shaft, the geological indications were such as to show a coal miner of ordinary mining knowledge and experience, to a reasonable certainty, that the bottom of the drill hole was either in or near a four foot vein of merchantable coal, then defendant should have prospected farther, either by farther sinking the drill hole he was then in, or by sinking’ another, or by some other test by which he could have ascertained as to the coal with a reasonable certainty, unless you find- that such a vein of coal does not lie under said shaft within a depth practical or profitable for working.”
The facts mentioned in this instruction might very properly have been taken into consideration by the jury in determining whether the defendant acted in good faith, and prosecuted his work to a reasonable depth. But these facts do not justify the. announcement of a rule of law that under ..such circumstances it was the duty of the defendant to prospect farther. Experience shows that as to the matter under consideration geological indications are often deceptive, and the opinions of experienced miners unreliable. Even in the present case the testimony shows that some of the experienced miners empiloyed by the defendant were of the opinion that the vein in the White Breast shaft had been passed long before the depth of three hundred feet was reached, and they advised the defendant to resort to drilling long before he ■ did so.
