after stating tbe case: Tbe issue of indebtedness between these parties is dependent largely upon disputed questions of fact, and these having been resolved against defendant by tbe referees and on relevant testimony, and their findings having been affirmed by tbe trial court, there is very little left for our consideration. It has been uniformly held, with us, that in actions of this character “Tbe findings of fact by a referee, supported by evidence and sustained by tbe trial court, are not reversible.” Malloy v. Lincoln Mills, 132 N. C., 432; Lambertson v. Vann, 134 N. C., 108. And we are of opinion that tbe exceptions to tbe conclusions of law were properly overruled.
Objection was made, first, to tbe conclusion on tbe part of tbe referees, that there bad been a wrongful delay on tbe part *303of defendant in the delivery of material, causing damage. This position predicated chiefly on the finding of fact No. 9, as follows: “That the plaintiff was at all times ready, able, and willing to perform the work in accordance with the terms of the contract, but was prevented from performing the same as required by the contract on account of the defendant’s failure to furnish the material as agreed and on account of the defendant’s delivering part of the material on the opposite side of a slough from the trestle or in a slough at such, point, rendering it necessary for plaintiff to haul said material about one-half a mile to get it to the place of construction. And, taken in connection with the requirement of the contract, “That defendant agreed to deliver all material for the trestle on ears or on the ground and within 300 feet of the trestle, and same is to be furnished in such a manner and time as not to impede said Brown in the performance of his part of the contract,” the ruling is clearly correct. In support of the finding, there was evidence on the j>art of plaintiff tending to show that a lot of heavy material was dumped on the ground about 300 feet from the trestle, in a direct line, but across a slough, which necessitated an additional haul of half a mile on part of plaintiff, causing delay and extra expense. There was no sufficient or satisfactory explanation offered as to the unloading of the material at such an inconvenient place. It is a principle well understood that in the interpretation of a deed or contract the intent of the parties, as embodied in the entire instrument, must prevail, “and each and every part must be given effect if it can be done by any fair and reasonable in-tendment. . . . ” Davis v. Frazier, 150 N. C., 447. And in a contract of this character and extent, requiring completion by a specified time, and containing, in connection with the provision for delivery within 300 feet, the further stipulation that the material was to be furnished in such a manner as not to impede the work, it was clearly contemplated and agreed that the material should be delivered within 300 feet of the work and at a point from which a haul could be made to the best advantage, having reasonable regard to the nature of the ground and the attendant facts and conditions. We think, *304therefore, that defendant was not justified in unloading the material just across a slough, causing the additional haul that plaintiff was forced to make, and the decision to that effect must be upheld.
It was further objected that in, the damages assessed against defendant for wrongful delay, there was included an item of $7 5 charged as a rental at $2.50 per day for a floating pile driver belonging to plaintiff and kept idle for a period of 30 days, the exception being that, according to our decisions, the correct measure of damages was the interest on the value of the machine, which would have amounted, at most, to about $13, defendant referring more especially to the case of Rocky Mount Mills v. R. R., 119 N. C., 693, in support of the position. That was a case in which the machinery and entire equipment for a cotton mill in process of construction was shipped to the address of the manufacturing company at Rocky Mount and over a fast freight through line, established by a number of carriers, associating themselves together for the purpose, at a higher freight rate, of assuring to the shipper a quicker and more reliable delivery of freight than by the ordinary methods of shipment. On negligent delay shown, the correct measure of damages was held to be the interest on the capital invested for the time of the delay, wages paid to workmen, and certain other costs and expenses incident to the breach of contract. In a subsequent case of Furniture Co. v. Express Co., 148 N. C., 87, the Court in affirming the principle applied in Rocky Mount Mills v. R. R., supra, and in reference thereto, said: “The decisions of this State are to the effect that the current profits.of a going manufacturing enterprise, which are dependent on the varying cost of labor and material and the fluctuations of the market value of the product, as a general rule, are too uncertain to form the basis of an award of damages in breaches of contract affecting the operation of the plant, and the better rule in such cases, when it appears that substantial damages are recoverable, is that such damages shall be ascertained on the basis of interest on the capital invested which is unproductive for the time, with the addition, under certain circumstances, of the pay of hands: idle and necessarily *305unemployed, and some other incidental expenses reasonably referable to the defendant’s wrong, wbicb may at times include an outlay in the reasonable effort to reduce or minimize the loss. No doubt there are cases where the average rental value of a business building or a given machine may afford data for a correct admeasurement of damages, but in plants of the kind indicated this rental value is so connected with or dependent upon the fluctuation of the markets that it has been considered with us as the safer rule in enterprises of the kind stated to adopt the interest on the capital invested and unproductive for the time, with other incidental costs, as the correct method of adjustment.” Citing Lumber Co. v. Iron Works, 130 N. C., 584; Sharpe v. R. R., 130 N. C., 613; Rocky Mount Mills v. R. R., 119 N. C., 693; Foard v. R. R., 53 N. C., 235; Boyle v. Reeder, 23 N. C., 607. It will be noted in this statement of the principle the current profits of such an enterprise, and even the rents, dependent as they naturally would be to a great extent on the current profits, are rejected as the proper basis, for the reason that they are too variable and indefinite; but decided intimation is also given that in the case of a business building or a given machine the average rental value frequently affords a more satisfactory estimate as to the amount of damages. Subject to the rule that the damages must have been in the reasonable contemplation of the parties and capable of ascertainment with a reasonable degree of certainty, the purpose is always to make good the loss to the injured party, and when a building or given machine is shown to have a definite rental value, and opportunity for obtaining same is lost by another’s breach of contract, the rental value for the time usually affords a better basis for the ascertainment and award of damages, and is a rule which has been not infrequently approved by the courts. Dodds v. Hakes, 114 N. Y., 260; Benton v. Fay Co., 64 Ill., 417; Hale on Damages, p. 74.
There was evidence on the part of plaintiff tending to show that the floating pile driver, in question, was an implement belonging to plaintiff, which could be and was not infrequently rented for a definite sum; that opportunity was presented to *306rent the machine in other work, and. that the time lost in its use was about 60 days, and a reasonable rental value for same was $10 per day. There was a finding of fact in accordance with the testimony, except that the time lost was fixed by the referees at 30 days and the net rental at $2.50 per day. On this finding we think the court below, approving the conclusions of the referees, correctly held that the rental value of the machine for the time the rent of sam% was lost afforded the correct basis for estimate, and that there is no error which gives defendant any just ground of complaint. The judgment will therefore be.
Affirmed.
