This is a trial de novo. In January 20, 1910, defendant gave to plaintiff a written order for a 20-horse power International, Type C, tractor gasolene engine; on March 29, 1910, an engine Avas delivered for Avhich he executed and delivered to the plaintiff two notes, a chattel and real estate mortgage securing the same, for the sum of $1,550, the first note falling due October 1, 1910. Defendant retained said engine and used it until October, 1910, Avhen he notified the plaintiff that he would not accept the same. The written order for the engine mentioned above contained the following provision: “The undersigned hereby acknowledges having received a true copy of this order, agreement, and warranty, as indorsed on the'back hereof.” The warranty reads as follows: “The International Harvester Company ■of America (incorporated) warrants the within described engine to do *76good work, to be well made, of good material, and durable if used with proper care. If upon one day’s trial, with proper care, the engine fails to work well, the purchaser shall immediately give written notice to the International Harvester Company of America, at Chicago, Illinois, and to the agent from whom it was purchased, stating wherein the engine fails; shall allow a reasonable time for a competent man to be sent to put-it in good order, and render necessary and friendly assistance to operate it. If the engine cannot then be made to work well, the purchaser shall immediately return it to said agent and the price paid shall be refunded, which shall constitute a settlement in full of the transaction. Use of the engine after three days, or failure to give written notice to said company and its agent, or failure to return the engine as above specified, shall operate as an acceptance of it and a fulfilment of its warranty. No agent has power to change the contract or warranty in any respect, and the within order can be canceled only in wilting from said company’s Chicago office. This express warranty excludes all implied warranties, and said company shall in no event be liable for breach of warranty in an amount exceeding the purchase price of the engine. If, within ninety days’ time, any part proves defective,- a new part will be furnished on receipt of part showing defect.”

Plaintiff had judgment in the court below for a foreclosure of the mortgage and defendant appeals. Although divided into many subdivisions by the assignments of error, we believe the contention of appellant may be narrowed to one, to wit, that the engine actually delivered was not the identical article ordered from the company. In support of this contention, plaintiff offered in evidence the testimony of conversations had by Alger with the sales agent, to the effect that the engine which plaintiff had for sale would develop 20-horse power as a tractor upon the drawbar. Among other things defendant testifies that the agent told him that the engine would draw a larger load than the Hart-:Parr 45-22 engine, and that it would do the work of sixteen horses, etc. This testimony is not offered, as we understand it, to show a breach of the written warranty above set forth, but merely to support the contention that the company did not deliver the engine described in his written order. He also offered in evidence statements of the same nature made in March, 1910, by one Smith, who came *77out to start the engine and who told him that the engine would do the work of sixteen good work horses, — ¡not ordinary farm horses, — sixteen good big horses. This evidence also was offered to show that the engine delivered was not the one ordered. Likewise, the testimony of defendant that one McManus, the local agent at Minot, made representations to defendant which induced him to believe the engine to be the one ordered, and to retain the same in his possession until fall. Finally, defendant testified that after plowing some 175 acres with the tractor, and keeping the same until October, he learned from the collector whom the company sent to his place, that the engine was only a 10-horse power by actual drawbar test, and he thereupon repudiated the entire transaction.

In other words, if we understand appellant, his contention is that a smaller weaker engine was substituted for the one ordered by him, and the cases cited in appellant’s brief are cases where substitution existed. It was expressly conceded through the whole argument that the engine in question was a good engine for its size, was well made, and gave perfect satisfaction in every respect excepting that it would not deliver 20-horse power at the drawbar, although it did deliver more than 20-horse power at the fly wheel by the brake test, and in all respects fulfilled its written warranty. After careful consideration of the evidence, which, of course, cannot be set forth in detail in the confines of this opinion, we have reached the conclusion that the evidence will not bear out appellant’s contention. In the first place the order calls for a trade article, a 20-horse power engine. And while the defendant himself testifies that it was understood by the sale agent that he desired to purchase an engine that would deliver 20-horse power at the drawbar, we do not believe such testimony impeaches the written order signed by the defendant which names only 20-horse power International, Type C, tractor gasolene engine. If defendant did not understand the trade meaning of this description, he could easily have ascertained the same from the dealer or from the company direct. The trade talk of the sale agent should not be relied upon to vary the terms of this written order.

Again, the fact that defendant kept and operated the engine nearly six months was a circumstance easting great doubt upon the sincerity of the defendant’s present claim. The evidence shows that defendant *78is a man of mature years, of more than ordinary intelligence, being a member of the bar of this state. We do not believe that he failed to understand the meaning of the order which he signed, nor the size and power of the engine when it was delivered to him. Nor do we believe he understood said order to mean that the company would deliver him an engine that would deliver 20-horse power at the drawbar. It also appears that this was the largest gas tractor engine at that time manufactured by the plaintiff. It is our judgment, sitting as we do as a. trial court in this action, that the engine which appellant ordered was delivered to him; that it complied in all respects with the warranty on which it was sold, and that he should pay therefor. This being the case, the judgment of the trial court is affirmed without a more detailed analysis of the legal points advanced.
