Defendant owns and operates an electric generating plant located within the city of Redwood Falls. On December 23, 1909, he entered into a contract with one Werring, by which he agreed to construct on the outskirts of the city a substation for the storage of electricity, and to deliver therefrom to Werring such electric current and energy as should be required by him, to be transmitted over his own wires to his patrons in other neighborhood municipalities. Werring assigned the contract to plaintiff, a corporation. Defendant constructed the substation, and thereafter delivered to plaintiff under *111the Werring contract such volume of electricity as plaintiff required. The contract called for the measurement at the substation, and defendant presented statements for amounts due which, under protest that an improper method of measurement had been adopted, plaintiff paid.

Plaintiff thereafter brought this action to recover an amount which it claims to be an overpayment, brought about by the improper measurement of the electric current delivered. The trial court found the facts in plaintiff’s favor and ordered judgment against defendant accordingly. Defendant appealed from an order denying a new trial.

The precise question in controversy is stated in the findings of the trial court substantially as follows: Defendant owns and operates the substation at which he delivers to plaintiff the electricity called for by the contract. Transformers are located at this station, and also a switchboard or device for measuring the current passing through the same. The current comes from the power plant of defendant at a definite voltage, but in passing through the transformers a certain amount of it is lost. The switchboard is placed in position for measuring the current as it enters the station, and defendant charges plaintiff for the quantity so delivered. It is the contention of plaintiff that it is liable under the contract only for such volume of electricity as is actually delivered after its passage through the transformers, while defendant contends that the quantity for which plaintiff is liable is properly measured by the volume delivered from the generating plant to the substation before it passes through the transformers. And, as remarked by the trial court, there is a loss of current at the substation, and the dispute narrows down to the question: Which party must, under the contract, stand the loss ?

The trial court applied the general rule that a vendor, who agrees to sell and deliver specific personal property of a certain kind or prepared in a certain way before delivery, must stand any expense or loss incurred by him in preparing the property for delivery, and held that the loss of electricity occasioned by the passage through the transformers at the substation must fall upon defendant. In this *112vieiv of the case we concur. Defendant agreed by tbe contract to sell and deliver to plaintiff a specified volume of electric current. The contract contains no reference to a loss naturally to occur at tbe substation, and no sufficient reason appears to justify tbe conclusion that tbe parties contemplated sucb loss in entering into tbe agreement, and that it should be cast upon plaintiff. Tbe contract calls for tbe payment of electric current delivered at the substation, and upon its face plaintiff can be chargeable with only sucb volume thereof as is actually delivered and received.

While the contract further calls for tbe measurement of tbe current at a switchboard to be placed at tbe substation, no provision appears therein justifying tbe conclusion that tbe parties understood or intended that this measuring device was to be so placed that tbe current would be measured before entering tbe transformers. Under the contract, properly construed, it should have been so placed as to measure tbe actual quantity delivered to plaintiff. It appears from tbe evidence and findings of the court that it could be placed on tbe delivery side of tbe transformers, but that tbe measurement at that point is attended with extreme danger, not incident to tbe measurement as tbe current enters tbe station. It seems clear that tbe sitution called for some express contract stipulations covering tbe matter, and tbe court cannot well say that tbe general custom of measuring from tbe low tension side of tbe station entered into or formed a part of tbe agreement and understanding of tbe parties. Tbe record contains no conclusive evidence that tbe parties discussed tbe subject of loss of current at tbe substation, at tbe time of or before tbe contract was entered into, and their rights must be measured in tbe light of tbe rule of law referred to and tbe actual stipulations embodied in tbe written agreement.

Order affirmed.
