(after stating the facts as above). The plaintiffs, to support the allegations of the complaint, offered the contract of sale in evidence, which, so far as it has relevancy here, is as follows;
“Portland, Oregon, October 15, 1906.
“Messrs. Everett Pulp & Paper Co., Everett, Wash.
“Bought of Meyer, Wilson & Co., 338 Sherlock Building.
“Terms: Net cash.
“Payable in IT. S. gold coin as delivered.
“About three hundred (300) to four hundred (400) tons, of 2,240 lbs. each, China clay in casks, P. X. Y. brand at seventy cents (70 cts.) per 100 lbs. net invoice weight ex ship at Beattie, Wash.
“This sale is made for shipment per ‘Mozambique’ from Leith or Tyne (P. M. W. & Go., A. T.) to Seattle. Purchasers to take delivery of China clay from alongside vessel at once on discharge at Seattle, Wash.
“China clay at risk of purchasers as soon as landed.
“Wharfage, if any, at Seattle, Wash., to be for account of purchasers.”
The plaintiffs having rested, ihe defendant offered in evidence, and they were received over the objection of plaintiffs, two letters, one bearing date Portland, Or., September 29, 1906, written by Meyer, Wilson & Co. to the Everett Pulp & Paper Company, and ihe other bearing date October 11, 1906, written by the Everett Pulp & Paper Company to Alfred Tucker, who represented the plaintiffs. The former reads as follows:
“Hear Sirs: Referring to the correspondence we had heretofore with you regarding China clay, we now have the pleasure of advising you that we send yon under separate cover a sample marked ‘P. X. X.’ of an English China clay which the makers believe matches your own sample very well, and we trust that you will find it so. It is probable that we could work your order for a quantity of not less than 400 to 500 tons of this P. X. Y. China c-lay in one-half ton casks with extra iron hoops, which packages have in our previous shipments proved very satisfactory, indeed, at the price of 76 % cents per 100 His. ex ship at Beattie; wharfage, if any, on the goods for buyers account, as usual. Will you kindly let us know whether you are inclined to place an order with us on this basis.”
The latter reads:
“Confirming the writer’s telephonic communication to you today; please enter our order for 3/400 tons of P. X. Y. China clay, to be fully equal to the sample winch you have submitted to us, at the price quoted by you, viz.: 70c per 100 lbs., ex ship at Beattie, duty paid.
“It is understood that this is to be packed in 5-cwt. casks reinforced with iron hoops, and is for Novembei'/Becember shipment.”
The first and third assignments of error are based upon the introduction of these letters, and they raise the question, not only as to the admissibility of such letters, but as to whether the contract sued on evidenced a sale by sample. It is insisted that the contract of sale is complete within itself, and that whatever correspondence took place previously between the parties relative to the purchase and sale of the clay has become merged into the contract, and therefore *862that the contract alone speaks of the transaction, and not the previous negotiations with respect thereto.
[1] As a general rule, it is undoubtedly true that all prior negotiations, whether in writing or by parol, or partly in writing and partly by parol, looking to the consummation of a contract or agreement between parties, become merged into the agreement when finally concluded and executed, and thereafter the previous writings or proposals and statements pro and con of the parties are incompetent and inadmissible to vary the force, effect, or terms of the consummated agreement. The principal reason upon which the rule is based is that:
“When parties, after whatever conversation or preparation, at last reduce their agreement to writing, this may he looked upon as the final consummation of their negotiation, and the exact expression of their purpose. And all of their earlier agreement, though ai>parently made while it all lay in conversation, which is not now incorporated into their written contract, may he considered as intentionally rejected. The parties write the contract when they are ready to do so, for the very purpose of including all that they have finally agreed upon, and excluding everything else, and make this certain •and permanent.” 2 Parsons on Contracts (7th Ed.) p. 679.
This conforms to the rule ás stated in Davis Calyx Drill Co. v. Mallory, 137 Fed. 332, 338, 69 C. C. A. 662, 668 (69 L. R. A. 973), that:
“Where tlie written contract of the parties is complete in itself, the conclusive legal presumption is that it embodies the entire engagement of the parties, and the manner and extent of their obligations, so that parol evidence of other terms is inadmissible to extend, modify, or contradict it.”
See, also, Rucker v. Bolles, 133 Fed. 858, 862, 67 C. C. A. 30.
[2] But,, whatever the rule may be upon the subject, the letters offered indicate that the letters “P. X. Y.” were used to designate a sample of English China clay, which was then submitted to the purchaser for its inspection, and not to designate any brand of China clay known to the market or in commerce. In other words, the letters were employed by the sellers merely to designate the sample which they were submitting to the buyer for inspection, and not any known commercial brand of the commodity sold in the market by such brand. The idea is undoubtedly confirmed by the subsequent testimony of Mr. Johnson, who says that the casks of clay received were none of them marked “P. X. Y.,” but all with a “Diamond A. Great Britain.” He further states that the letters simply referred to the samples of clay submitted for the buyer’s examination.. These letters, therefore, serve not to contradict, vary, add to, or take from the contract of sale in the least, but only to explain what, without their aid, is obscure and ambiguous, for which purpose they were clearly admissible. Such was the purpose for which they were admitted by the Circuit Court.
[3] When read in the light of these letters and the subsequent testimony of Johnson, it is perfectly manifest that the contract is evidentiary of a sale by sample, and not of a certain quality of material by a designation known to the trade or in commerce. Assignments of error Nos. 1 and 3 are therefore not well taken.
[4] Assignments of error Nos. 4, 9, and 10 relate-to testimony ad*863mitted over objection, which tended to show that the clay rejected contained a larger percentage of grit, which rendered the paper with which it is used for the manufacture of certain kinds of writing paper spotted and unmerchantable, atid, further, that so large a percentage of grit had the effect to 'wear out quickly the appliances for manufacturing the paper, thus rendering the manufacture of the finished article much more expensive. The purpose of this testimony was to show that a large portion of the clay delivered did not conform to the sample. It was therefore relevant to the inquiry, and no error was committed in admitting it.
Assignment of error No. 13, which we take up now because of its logical sequence, is based upon a motion interposed by plaintiffs when the parties respectively had rested for judgment on the pleadings, and for verdict: and judgment upon the case: the reasons assigned therefor being: First. That the defendant has pleaded in its answer, and its evidence proved, that it liad accepted 861 casks of clay which conformed to the sample submitted, and that it had rejected 606 casks which were alleged to be inferior to the sample. Second. That, under and by the pleadings, the defendant has not counterclaimed for any damages sustained by reason of the alleged breach of warranty, and hence none can be allowed. This motion was overruled, and judgment was entered to the effect that plaintiffs take nothing by the action save and except the money deposited with the clerk by the defendant, namely, 83,424.75, and that plaintiffs pay tlie costs of the action accruing subsequent to making the deposit.
Counsel for plaintiffs insist that there was error in denying this motion, and rely upon four propositions to support their contention: First. That a discharge of the clay ex ship, or at tlie side of the vessel upon the wharf at Seattle, was a delivery of the entire consignment. Second. That the contract of sale was entire, and that an acceptance by the buyer of a part of the clay was an acceptance of the whole. Third. That, where there is an attempted rescission of the contract, a subsequent retention of the goods works a waiver of the rescission. Fourth. That under the ’pleadings defendant is entitled to nothing by way of counterclaim or recoupment.
These propositions entail a discussion of the law relating to sales by sample, and somewhat of the rules of pleading relative to recoupment for damages. It should be premised that the court neither made findings of fact nor rendered any conclusions of law.
[ 51 The general conclusion that the plaintiffs should take nothing except the money deposited is tantamount to a general verdict of a jury, and we are not permitted to look into the evidence for determining whether the conclusion was properly deduced.
[6] We could not do so even if it were proper, because the record does not contain all the evidence adduced at the trial. Nor can the written opinion of the court be considered as a finding of facts. It shows the conclusion of the judge upon the facts and the law, but cannot be treated as a finding of conclusions of either fact or law.
[7] A sale by sample is tantamount to an undertaking on the part of the seller that the goods sold shall be similar both in nature and in *864quality to the sample exhibited, and imports an implied warranty to that effect. There is some discussion in the books as to whether the rule extends so far as to require correspondence in both kind and quality, but We take it that the broader acceptatiori of the rule is, under the authorities, the better one, and that the implied warranty _is of both kind and quality. See Wadhams v. Balfour, 32 Or. 313, 51 Pac. 642, where many of the authorities are collated and discussed. See, also, Pope v. Allis, 115 U. S. 363, 6 Sup. Ct. 69, 29 L. Ed. 393, and 35 Cyc. 405. Necessarily there is a condition attending such a sale that the buyer shall have reasonable and, fair opportunity for examining or inspecting the bulk of the goods sold and comparing them with the sample exhibited, and thus determining for himself whether they are in fact of the same or similar kind and quality as represented. ,
[8] An acceptance cannot be predicated of the mere receipt of the goods, unless the opportunity has been offered for examination, as the right of examination attends the sale as a condition precedent to acceptance, unless -waived by some act or stipulation of the buyer. The condition may be regarded as fundamental, and absolute acceptance cannot be expected or enforced without the buyer be given or may have exercised such privilege.
[9] It is doubtless the rule that, where the contract is entire, the buyer has not the right to accept the goods in part and reject them in part. Such a contract is riot thus severable. The goods must be accepted as a whole or rejected as a whole. It is also true that a pai'ty under such a 'contract cannot accept and keep part of the goods, and at the same time rescind the contract. To rescind, he must place the seller in statu quo by returning or offering to return the goods, xiot a part of them, but all that has come to his possession, so as to restox'e previous conditions. Failing this, the purchaser cannot insist upon rescission.
[10] Furthermore, as a general principle, an acceptance of a part of the goods uxider an indivisible contract of sale, wlxere there is opportunity for full inspection, is tantamount to an acceptance of the whole, but such acceptance, or even a general acceptance, is not a waiver of warranty as to .kind or quality attendirxg the sale. See in support of these propositioxxs Buckeye Buggy Co. v. Montana Stables, 43 Wash. 49, 85 Pac. 1077, 117 Am. St. Rep. 1032; Manss-Bruning Shoe Mfg. Co. v. Prince, 51 W. Va. 510, 41 S. E. 907; Clark v. Baker, 5 Metc. (Mass.) 452; Morse v. Brackett, 98 Mass. 205; Reynolds v. Palmer (C. C.) 21 Fed. 433; Crane Co. v. Columbus Const. Co., 73 Fed. 984, 20 C. C. A. 233; Lenz v. Blake, 44 Or. 569, 76 Pac. 356; Nash v. Weidenfeld, 41 App. Div. 511, 58 N. Y. Supp. 609, 611.
Now, as to the remedies of the buyer, it is said in Pope v. Allis, supra, that a sale by sample “amounts to an undertaking on the part of, the seller with the buyer that all the goods are sixnilar, both in nature and quality, to those exhibited, and, if they do not correspoxid, the buyer may refuse to receive them, or, if received, he may return them in a reasonable time allowed for examination, and thus rescind *865the contract.” And in Beirne v. Dord, 5 N. Y. 95, 98 (55 Am. Dec. 321):
“"When a contract for tbe sale of goods is made by sample, it amounts to an undertaking on the part of the seller, with the purchaser, that all the goods are similar both in nature and quality to those exhibited: and, if they be not, the purchaser may either rescind the contract, by returning the goods in a proper time, or keep them and recover damages for the breach of such warranty.”
Then again, in Clark v. Baker, supra (5 Metc. [Mass.] p. 461), which involved a sale of corn with warranty, the court says:
"The plaintiff's redress was easy — either to rescind the contract by returning all the corn purchased and suing for the money advanced, or by action upon his warranty, for the injury sustained by the delivery of an article inferior to that, warranted.”
[11] The Circuit Court was of the opinion that the sale in question was a sale by sample. Being such, the buyer had the right to inspect the clay before acceptance. In the exercise of this right, if reasonable opportunity was afforded, it should have made the inspection upon the wharf at the ship’s side when unloaded. But, if no such opportunity was there afforded, the buyer was privileged to make the inspection at some other place, where convenient and reasonable test could be had, so that it might satisfy itself of the kind and quality of the article consigned to it; and it may be that it was not unreasonable to take the clay to its mill at Everett for the purpose of making the test. This being a question of fact to be disposed of under the evidence, we are not in a position to pass upon it, and hence cannot say that the trial court erred respecting its conclusion in the premises, whatever it may have been.
This disposes as well of the sixth, seventh, eighth, and twelfth assignments of error. The sixth relates to the testimony of Johnson respecting the defendant’s taking possession of the clay upon the dock at the ship’s side and transporting it to Everett; the claim being with reference thereto that the act-was an acceptance of the clay on the part of the defendant. The seventh, eighth, and twelfth relate to evidence adduced, over objection, touching an alleged custom existing in Seattle that clay of the kind is inspected elsewhere than upon the wharf where discharged from the ship. We simply say' that these are questions of fact, and are not properly before us for determination.
[12] This brings us to a consideration of plaintiffs’ motion for judgment on the pleadings. The contention is that defendant cannot recoup damages (which is, in effect, what was granted by the judgment of the Circuit Court) because it has not set up the same by way of counterclaim. Breach of warranty respecting the kind and quality of goods sold should be set up by way of counterclaim showing the damages suffered by reason thereof, thereby seeking to recoup the same against any demand the plaintiff may have against the defendant. Nash v. Weidenfeld, supra; Sloan Commission Co. v. Henry A. Fry & Co., 4 Neb. (Unof.) 647, 95 N. W. 862. In some jurisdictions the breach is regarded as a defense pro tanto, as upon a failure of *866consideration; in others it cannot be pleaded as a defense, the goods being retained, but only as a counterclaim. 35 Cyc. 442.
But, however this may be, a careful analysis of the answer discloses its true and only purpose and character. The defendant,. “further answering the complaint,” first sets out the contract according to its understanding: That the clay, when delivered on the wharf of Galbraith-Bacon & Co. at Seattle, was forwarded to defendant’s factory at Everett, whereupon, on inspection, 861 casks were found to conform to the sample submitted (P. X. Y. brand), and 739 casks to be inferior to the sample; that defendant notified the plaintiffs immediately, and refused to accept the shipment; that at the time defendant discovered that clay of an inferior grade was included in the shipment 253 casks still remained on the wharf; that, plaintiffs being notified that the shipment was not in accordance with the sample, after some correspondence it was agreed that the defendant should take to its plant at Everett the remaining 253 casks, without admission,of liability for shipment, and without expense to it if defendant’s claim as to the inferiority of the clay should prove to be correct; that of the 253 casks, 133 were of the poorer brand, inferior to sample, and are now held by defendant as the property of plaintiffs, subject to their order, together with the 606 casks inferior to sample also in the hands of the defendant; that defendant has offered, and is now ready and willing, to return the 606 casks to the wharf at Seattle without expense to plaintiffs, and here and now offers to do so; that the value of the 861 casks is $3,375.12, and interest thereon from October 12, 1907, to date of answer, $50.63; that defendant herewith brings into the registry of the coux*t $3,425.75, and prays that plaintiffs recover no judgment, and that the action be dismissed without costs to the defendant. This answer in both theory and practical effect proceeds upon the one idea that the buyer might lawfully •accept the goods in part and refuse them in part, and in doing so would be relieved of all liability as to the part rejected. In the mind of the pleader the question of damages-cut no figure, and it was assumed that it was only a matter of returning the clay rejected, or tendering a return, and that thereby the defendant acquitted itself of liability to the extent of the price of the clay rejected. Such is not the law. An acceptance of a part of the clay, which is shown by the answer, was tantamount to .an acceptance of the whole, but such acceptance was not a waiver of the warranty as to kind and quality. The plaintiffs were not bound to receive back the rejected clay, but are liable in damages for a breach of their warranty, the measure of which is the difference in value of the clay comporting with the sample, or the consideration stipulated, and value of the rejected or inferior article, not the entire consideration or value of the clay rejected. The answer excludes all idea of damages of this sort, and theoretically proceeds upon a wholly contrary idea, namely, that of a rejection of the clay in part and a rescission of the contract pro tanto, which, as we have seen, could not be done.
[13] After etj acceptance of- a part of the clay, defendant’s relief lay wholly in recoupment of damages for breach of the warranty. *867The answer, while alleging facts which show a breach in part of the contract to deliver clay of a certain kind and quality, alleges no damages, and prays for none, and it cuts off inquiry as to the rightful and proper damages to which the defendant is entitled by way of recoupment — that is to say, the difference between the value of the sound article and the value of the inferior article not conforming to the sample — and leaves the plaintiffs no choice but to take back the clay rejected, and relieve the defendant from liability for the entire purchase price therefor. The Circuit Court, while deciding the case upon the theory that defendant was entitled to recoup damages sustained for breach of warranty, seemed to be of the view that an offer to return the inferior clay entitled the defendant to damages equal to the entire purchase price, which is an erroneous view of the law. We quote from the court’s opinion:
“The measure of damages which the vendee may claim for breach of an implied warranty of quality is the difference between the actual value of the property delivered and the higher value of the warranted quality; and, if there is no other evidence of value, the price agreed to be paid will be regarded as the value of the property of the quality warranted. In this case the defendant having offered to return the inferior clay and to hold it subject to disposition by the plaintiffs, the contract price is the measure of damages which it is entitled to recoup.”
We are of the opinion that the answer as it stands, proceeding as it does solely upon the theory of a rescission in part of the contract of sale, and of a right to recover the consideration price pro tanto, and excluding by its very draft all idea of damages for breach of warranty, entiLled the plaintiffs to judgment on the pleadings. At least, if damage for breach of warranty was the real defense, the plaintiffs were entitled to notice of such a defense, through appropriate answer, and to an opportunity to make contest upon the basis of the proper measure of damages in the premises. '.Phis, it is quite evident, the plaintiffs were not accorded. The Circuit Court was therefore in error in not granting the motion for judgment.
Since the defendant in error now asks, if the cause is remanded, that it be allowed to amend its answer, the judgment of the Circuit Court will he reversed, with direction to said court to allow the defendant leave to amend its answer so as to entitle it to recoup such damages as it has sustained by reason of any breach of plaintiffs’ warranty.
