Smith, P. J.

This was a suit on a promissory note executed by David Ball, who has since died, to plaintiff, for the sum of $72.50, and due twelve months after the date thereof. Defendant’s answer is as follows : *508“Defendant, for Ms answer to plaintiff’s petition, herein denies each and every allegation therein, except as hereinafter specifically admitted; and for further answer and defense defendant states that he made the note described in plaintiff’s petition herein, and that said note was wholly without consideration, and that said note was given as and for the purchase price of, and delivery and erection of, in a skilful and workmanlike manner, one windmill, and agreed that said windmill would stand satisfactorily when erected, and would not fall down by reason of negligence, defect or carelessness in the manner of erecting said windmill. And that said windmill would not blow down from any storm that did not blow down permanent structures. Defendant further states that plaintiff delivered and erected said windmill, and that said windmill was erected by said plaintiff in a careless and unworkmanlike and negligent manner, and as a result and by reason of said negligent, careless, and unworkmanlike manner in which said mill was erected by plaintiff the said windmill fell down, and not as the result of any storm that did blow down permanent structures, soon after it had been erected, as aforesaid, and of which fact plaintiff received notice ; and while plaintiff was erecting said windmill this defendant objected to the manner in which it was being erected by plaintiff; that thereupon plaintiff stated, to defendant that it would stand and work satisfactorily, and 'that it was guaranteed to stand and work satisfactorily ; that thereupon this defendant executed the note described in plaintiff’s petition upon the condition and consideration' aforesaid, and defendant further states that said windmill had been of no use or benefit to him since the erection thereof, and that the whole consideration of said note has failed, and the destruction of said windmill was caused wholly by the negligence of plaintiff’s agent in erecting the same as aforesaid, and by reason thereof the defendant has been deprived *509of the use and benefit of said mill, and has been damaged in an amount of said note and interest,” etc. The replication was a general denial. The evidence and instructions will be noticed further on. The plaintiff had judgment and the defendant appealed.

I. It will be perceived that the answer of the defendant puts the defense on two grounds, first, a breach of the warranty therein alleged, and, second,, the negligent erection of the mill by the plaintiff. The principal complaint here made by the appealing defendant arises out of the action of the circuit court in giving instructions, numbered 1 and 2, for plaintiff, and in refusing numbers 7 and 8 asked by defendant.

The first instruction given for the plaintiff told the .jury that the execution' of the note being admitted they should find for the plaintiff the amount and interest thereon, unless they further find that at the date of the execution of the note the plaintiff warranted the mill or its manner of construction and putting up, and that the same was blown down by reason of the defective erection or manner of putting up the same. The defendant contends this instruction is erroneous, first, because it required the jury to find for plaintiff unless it found plaintiff warranted the mill and that the same was blown down by reason' of defective erection, and, second, because the court did not define the word, warranted, or tell them what facts would constitute a warranty. As to the first of these objections, it is sufficient to say that, if the theory which it presented for the consideration of the jury was erroneous, a like error is to be found in the first instruction asked by the defendant, and given by the court. Communis error facitjus.

And as to the second ground of objection, it maybe remarked that in the sales of personal property a warranty has been defined to be an express or implied statement of something which a party undertakes shall *510be part of the contract, and, though part of the contract, collateral to the express object of it. Benj. on Sales, 600. So that the term, “warranty,” is a technical one, and it may be said, without any reflection, that no court would be justified in presuming that the signification of this term, where employed in an instruction, is well understood by the average juror. It, therefore, seems that the circuit court should have defined by an instruction this term and then have told the jury further what were the essential facts to be found under the pleadings to constitute a warranty so defined. Proctor v. Loomis, 35 Mo. App. 482; McGinnis v. Railroad, 21 Mo. App. 399. The instruction under consideration was so framed as to either embarrass and confuse or mislead the jury, and was, therefore, improperly given.

II. The second instruction given for the plaintiff told the jury that “ if the mill was erected with reasonable care and skill, sufficiently strong to stand all ordinary storms, and that the same was blown down by an extraordinary storm or by reason of water standing around where said mill was erected, or by reason of defective posts furnished by defendant without fault on part of plaintiff’s agent, the jury will find for plaintiff.” The defendant contends that the instruction is based upon facts of which there is no evidence. Upon a close examination of the record we have been unable to find the slightest evidence to warrant the assumption of the instruction that at the time the mill blew down that water was standing around where it -was erected, or that defective posts were furnished by defendant for the erection of the mill. The evidence showed the ground where the mill was erected was overflowed about the middle of June, and the storm which blew down the mill occurred on the ninth day of August. The only evidence as to the condition of the ground at the time the mill fell down was that, “ it was hard and dry.” The posts on which the mill was erected pulled loose *511from tlie anchors, which were left in the ground where they had been placed. The ground was hard gumbo and clay. There was evidence that defendant furnished the posts and anchors used in connection therewith, but no evidence whatever was offered tending to show that the posts were defective. The instruction, if otherwise unobjectionable, had no evidence, as we have seen, on which to rest, and, for that reason, should have been refused. Gerren v. Railroad, 60 Mo. 405; Musick v. Railroad, 57 Mo. 134; Peck v. Richey, 66 Mo. 114; Pipkin v. Haucke, 15 Mo. App. 373. If the plaintiff erected the mill in question with reasonable care and .skill and the same was destroyed by a cyclone, earthquake, by lightning or by any other natural cause diseonnected with any fault or negligence of the plaintiff, it is likely it would not be answerable for the destruction of the mill. The jury should have been left under proper instructions to have determined whether the destruction of the mill was caused by the negligence of the plaintiff or by a storm of such violence as to be called the act of God — vis divina — making it practically impossible for the mill to resist it. If attributable to the first cause, then the defense would be sustained, and if to the latter it would fail.

Though no such question has been made here, we are inclined to think that, under the code as it now exists in this state, the facts relied on in the instruction should have been set forth in the replication. The plaintiff by merely denying the allegations of the defendant’s answer could only try such questions of fact as were necessary to sustain the defendant’s case. The rule is that, whenever a defendant intends to rest his defense upon any fact which is not included in the allegations necessary to the support of the plaintiff’s case, he must set it out according to the statute in ordinary and concise language, else he wall be precluded from giving evidence of it upon the trial. An affirmative defense should be clearly and distinctly set forth. *512Northrup v. Ins. Co., 47 Mo. 435; Musser v. Addler, 86 Mo. 445; Donovan v. Railroad, 89 Mo. 147; Rees v. Garth, 36 Mo. App. 641. This rule is applicable to the pleading in this case for the reason that the answer is analogous to a petition grounded on negligence — the replication thereto corresponding to the answer.in such a case. The plaintiff’s second instruction was based on a defense not raised in the replication, and was, therefore, improper. Storms v. White, 23 Mo. App. 31; Laramore v. Legg, 23 Mo. App. 645; Glass v. Gelvin, 80 Mo. 457; Mossman v. Bender, 80 Mo. 579; Melvin v. Railroad, 89 Mo. 106.

III. As to the seventh instruction, which told the jury to constitute a warranty it was not necessary that the word, “warranty,” or any particular word should be used in the contract, but if they believed from the evidence that expressions were used by plaintiff from which defendant had reasonable ground to suppose a ivarranty toas intended' from the plaintiff and that he did so suppose, and in making the purchase relied ujDon such supposed warranty, the jury should find there' was a warranty in fact, — this instruction is not quite accurate. It does not meet the requirements of the rule laid down by the supreme court in Carter v. Black, 46 Mo. 385, and in Barker v. Scudder, 56 Mo. 272. With the correction that a perusal" of these cases will suggest, the instruction would be well enough.

IY. The defendant’s eighth instruction, which was-refused, which told the jury that no private restrictions upon an agent’s authority unknown to the purchaser can affect such purchaser, etc., should have been given. It asserted a correct rule in respect to the power of agents in such cases. Brownfield v. Ins. Co., 26 Mo. App. 398; Hayner v. Churchill, 29 Mo. App. 676. It results from these observations that the judgment will be> reversed and the cause remanded.

All concur.
