The opinion of the court was delivered March 22d 1847.
Dewey, J.The extent to which local usages of trade are to be applied, in the construction and effect to be given to contracts, is a matter by no means free from difficulty. These usages differ essentially from those more general customs, which are known and exist as part of the general law of the land, and which are observed and applied without being established by evidence offered in each particular case. . These local usages may be of comparatively recent origin, and may be limited to a single city or village; and yet, if reasonable in their provisions, and so generally adopted by those concerned in any peculiar branch of business, as to authorize the presumption that they are known by those who are dealing as vendors and vendees in that branch of trade or business, the dealings and contracts of such persons are considered to have been made in reference to such usages, and to be governed thereby. Learned jurists have often expressed their regret at the extension of this species of evidence, and especially that as to usage of a local and limited character, as impairing, in some degree, the symmetry of the law, and tending to uncertainty and embarrassment in the administration of justice, and also liable to the serious objection, that the knowledge, by the party to be affected by it, of the existence of such usage, is a mere legal presumption, which may often be unfounded in reality, although such usage is established by what is deemed competent legal evidence. Notwith*189standing these objections, such local usages have been held admissible by the judicial tribunals, as competent to explain and qualify the contract, and give to it an effect materially different from that which the general law would have done, in the absence of all evidence of such usage. The cases are too numerous to cite in detail, and I will only refer to them generally, as fully collected in the notes to 1 Smith’s Leading Cases, (Amer. ed. of 1844) 418.
In the present case, the usage found by the jury goes directly to establish a rule in contravention of the rules of the common law, in relation to rescinding a contract in a case of sale of an unsound article, accompanied by a warranty, or induced by false representations. The general rule of law requires the vendee, if he would rescind the sale for such cause, to restore the entire commodity purchased. The local usage proved is, that in a sale of corn under like circumstances, the party may keep so much of the commodity as answers the warranty or representation, and decline taking the residue ; that is, he may rescind the contract in part, and, without returning the corn he has received, may recover back the money paid for so much of the article as does not answer the representation. This usage is certainly not an unreasonable one, and not to be rejected upon that ground. The nature of the commodity, the manner of exposing the article for sale, the price being fixed by the bushel, and the mode of delivery, all alike point out this as a reasonable and convenient usage. We understand the contract to have been an oral one. Such being the case, the admission of the evidence of the usage is not objectionable upon the ground of its being offered to control, vary or contradict a contract in writing. Nor does the usage contradict any express oral contract made by the parties. Had it done either, it would have presented a very different question.
Usages of this character are only admissible upon the hypothesis that the parties have contracted in reference to them. If the parties make express stipulations as to the terms of a sale, or the manner of performance of a contract, or state *190the conditions upon which it may be rescinded, such express stipulations must be taken as the terms of the contract, and they are not to be affected by any usage contrary to them
Looking at the usage relied upon in the present case, and taking it to have been found by the jury to be well established by the proof, as a general usage of the dealers in similar commodities, in Boston, and finding the same is not repugnant to any express stipulation in the contract of the parties; without any disposition on the part of the court to extend the doctrine of local usages beyond the adjudicated cases, yet we have not felt authorized to reject the evidence offered in the present case.
Upon the remaining point raised in the case, the court are of opinion, that the duty of separating the merchantable corn from that which was not so, where there was any considerable quantity damaged, was a duty devolving upon the vendor. He sold the corn as of a certain quality. If a separation of one portion of it from another was necessary, to furnish corn of the proper quality to correspond with that stipulated for, the labor of doing this properly devolved upon the vendor, and the refusal of the vendee, before such separation, to receive the commodity, would not excuse the vendor from the duty of separating and offering the merchantable corn, if he would entitle himself to carry into effect the contort, and require the vendee to take all the corn corresponding to the representation.
The ruling of the presiding judge at the trial was - meet, and judgment must be entered for the plaintiff.
