Robinson v. United StatesRobinson v. United States
delivered the opinion of the court.
In Barnard v. Kellogg, ‡ this court decided that proof of a custom or usage inconsistent with a contract and which either expressly or by necessary implication contradicts it, cannot be received in evidence to affect it; and that usage is not allowed to subvert the settled rules of law. But we stated at the same time that custom or usage was properly received to ascertain and explain the meaning and intention of the parties to a contract, whether written or parol, the meaning of which could not be ascertained without the aid of such extrinsic evidence, and that such evidence was thus used on the theory that the parties knew of the existence of the custom or usage and contracted in reference to it. This latter rule is as well settled as the former, § and under it the evidence was rightly received.
It is obvious by the steps which the plaintiffs took to perform their contract, that there are two modes in which barley may be delivered, for they delivered part in sacks and tendered part in bulk. And it is equally obvious, on account of the additional cost, that they would not have delivered the barley in sacks for a period of six months, if the contract on its face was satisfied by a delivery in bulk.
The evidence in the present case did not tend to contradict the contract, but to define its meaning, in an important point, where, by its written terms, it was left undefined. This, it is settled, may be done.
It is objected that the usage was proved by a single witness. But we cannot assert, as a rule of law governing proof of usages of trade, that if a witness have a full knowledge and a long experience on the subject about which he speaks, and testifies explicitly to the antiquity, duration, and universality of the usage and is uncontradicted, the usage cannot be regarded by the jury as established. On the contrary, the authorities are that in such a case it may be. *
Judgment affirmed.
