This action was brought at law, to recover double damages for the alleged killing of two cows by the operation of defendant’s railway train. The petition contains the usual allegation of defendant’s failure to properly fence its right of way, and that by reason thereof plaintiff’s cows went upon the railway track, where they were struck and killed by defendant’s train. The value of the animals was alleged to be $400. It was further averred that plaintiff had caused notice and affidavit of such loss to be served upon defendant more than 30 days before the action was begun; and judgment was demanded for $800.
Defendant denied the allegations of the petition generally. There was a trial to a jury, which returned verdict for plaintiff for $300. Motion for new trial was denied, as was also a motion by the defendant for a reduction of the amount of the verdict.
x' MuSg0o?Sstoek: proximate cmsn as jury question. I. The defendant’s first proposition for a reversal'of the judgment below is that the verdict of the jury has no support in the evidence. The point is not well taken. It is true that no witness testifies to seeing the alleged killing, but it has been too often held that such fact may be shown by circumstantial evidence to justify p^g^g argue the proposition of law.
That the rule has support in our own cases is abundantly shown by the precedents cited by the appellee. Van Slyke v. Chicago, St. P. & K. C. R. Co., 80 Iowa 620; Brockert v. Central Iowa R. Co., 82 Iowa 369; Daugherty v. Chicago, M. & St. P. R. Co., 87 Iowa 276; Kennedy v. Chicago & N. W. R. Co., 90 Iowa 754; Cox v. Burlington & W. R. Co., 77 Iowa 478. In this case, there is no evidence tending to show that the two cows found lying dead by the track died of disease, or were killed by lightning or violence of any kind, other than was inferable from the fact that the defective fence afforded an entrance for the stock to the track; that the dead bodies lay at the foot of a steep slope from the track, down which slope the bodies would be *1070likely to bave been thrown by collision with a moving train; that tbe bodies, or at least one of them, showed visible external marks of injury; that the moving or twisting of the heads of the carcasses produced grating sounds, as of broken bones; that from the track to the carcasses there was a trail broken through the weeds, such as might have been produced by their falling or sliding down the slope, — 'all of which, and the absence of any other reasonable theory or explanation of the killing by other means, fully justified the conclusion of the jury that the animals were injured by a train moving on the defendant’s railway. Appellant claims, in effect, that circumstantial evidence is insufficient unless it excludes every other hypothesis than the negligence of the defendant. The rule contended for is often applied in criminal cases; but it is thoroughly well settled that, while plaintiff cannot recover upon evidence of circumstances which show no more than a possibility that the injury is chargeable to the defendant’s negligence, he is not bound to prove either negligence or proximate cause beyond a reasonable doubt. Proximate cause is, under all ordinary circumstances, a question of fact; and where it depends upon circumstances from which reasonable minds may reasonably draw different conclusions, or where all the known facts point to the negligence of the defendant, the submission of the question to the jury is not error. 29 Cyc. 632; Brownfield v. Chicago, R. I. & P. R. Co., 107 Iowa 254, 258; Schoepper v. Hancock Chemical Co., 113 Mich. 582; Jucker v. Chicago & N. W. R. Co., 52 Wis. 150; Lunde v. Cudahy Pkg. Co., 139 Iowa 699. To call for the application of the rule contended for by appellant, it must appear that the proved facts are at least equally consistent with some other reasonable theory than the fault or negligence of the defendant. The record in the instant ease is quite barren of proof of that kind. The finding of defendant’s negligence has sufficient support in the testimony.
2 Raixjroads ■ excessive0demand. for stock killed, II. More than 30 days before this action was begun, the plaintiff served written notice of his loss upon the defendant, together with an affidavit Stating the value of the animals killed to be $400, and demanding payment of that amotint- In submitting the issues to the jury, -fog court charged that, if plaintiff had estab-*1071lisbed tbe fact tbat bis stock bad been killed by defendant’s train, and tbat sueb injury was occasioned by reason of defendant’s failure to properly fence its right of way, then plaintiff was entitled to recover double the actual damages so sustained by him. As to tbe form and substance of a verdict for plaintiff, the court gave tbe following instruction:
“If, guided by these instructions, you find for tbe plaintiff, then you will determine tbe actual value of said cows at tbe time of their death, and return your verdict in favor of tbe plaintiff for twice or double tbe amount of such actual value as found by you, without interest. But in no event can your verdict exceed tbe sum of $800.”
3 raileoads-íossUof s°toci?°e: ^tfSaSdí¿ot" veidict. The jury returned a general verdict for tbe plaintiff, assessing bis recovery at $300. Thereupon, the defendant moved that judgment be entered upon said verdict in favor of plaintiff for $150, and no more, on the ground tbat, as-turning tbe jury to have followed the instruc-ti°n quoted, the actual value of tbe cows must have been assessed at $150, and plaintiff having demanded payment of $400, a sum far in excess of tbe real damage sustained by him, he cannot be allowed to recover tbe penalty. This motion was denied, and defendant assigns error on the ruling. Judgment was entered for plaintiff upon tbe verdict for $300; and to this, exception is also taken.
Under tbe statute providing for tbe recovery of double damages (Code Section 2055) and tbe decisions of this court construing and applying its provisions, we are constrained to bold tbat there was prejudicial error in tbe instruction' last above quoted, to tbe effect that a finding for plaintiff would, as a matter of law, entitle him to an assessment of double damages. Under the issues joined, a finding by tbe jury tbat the animals were killed by defendant’s train, by reason of defendant’s failure to properly protect its track by fence, as required by law, would entitle plaintiff to recover his actual damages, even if be had failed to show compliance with tbe statutory condition for recovery of double damages. To recover double damages, be was required to make tbe additional showing that, 30 days or more before the suit was begun, he had given defendant notice in writing, accompanied by affidavit, of tbe loss be had *1072so sustained, and that defendant failed to make payment of bis demand. We bave beld that tbe spirit, if not tbe letter, of this statute requires that this notice shall state tbe amount of the actual damage tbe plaintiff claims to bave sustained (Manwell v. Burlington, C. R. & N. R. Co., 80 Iowa 662, Mendell v. Chicago & N. W. R. Co., 20 Iowa 9, 11), and that failure to give such notice will defeat tbe right to recover more than compensation for tbe actual injury. We bave further beld that, in order to recover double damages, tbe plaintiff must state in good faith, in bis written notice of loss, tbe amount of bis actual damage, thereby giving tbe railway company tbe opportunity, if so disposed, to make good to him bis actual loss, unburdened by any penalty. In so ruling, we bave said that “to bold plaintiff can fix bis damage at any sum, however exorbitant or unreasonable, and demand of tbe company, through tbe notice, an adjustment and settlement at that amount, or be liable for double the actual amount,” would be clearly unjust. Binder v. Chicago & N. W. R. Co., 162 Iowa 550. In the cited case, the plaintiff, in his notice to the company, bad stated tbe value of tbe animals killed at $450, while tbe jury assessed tbe value at only $275; and.this discrepancy was beld sufficient to require submission to tbe jury of tbe question of plaintiff’s good faith in making tbe excessive demand. Later, in Pierce v. Chicago & N. W. R. Co., 180 Iowa 1385, the plaintiff’s notice of loss stated the value of the animal killed at $200. Suit was brought to recover double damages in tbe sum of $400. Tbe verdict of tbe jury was for $380. We there went a step further than in tbe Binder case, and held,- in effect, that, as double damages are in tbe nature of a penalty for failure to pay a just demand, they ought not to be imposed in any ease where tbe demand is excessive. Such being tbe conclusion as to tbe effect of tbe statute, we there beld that tbe trial court erred in refusing tbe defendant’s motion for tbe entry of judgment for actual damages only, as indicated by tbe verdict returned.
III. Counsel for appellee makes the point that defendant in this case did not plead or charge bad faith on plaintiff’s part in making bis demand for $400 actual damages. We think, however, that tbe right of tbe defendant to resist payment of double damages is not conditioned upon its ability to show bad faith in *1073tbe plaintiff. It is enough if tbe demand made is clearly excessive.
It is further argued that the evidence is undisputed that one of the cows killed was of the value of $250, and that the other (the one showing visible external marks of injury) was of the value of $150; and that the verdict is explainable on the theory of a finding for plaintiff for double the value of the animal last mentioned, and should be sustained for that amount.
It is not within the province of the court to thus amend the verdict, or to speculate upon the reasons leading the jury to its conclusion. The notice of loss given the company and the demand for damages were for the single gross sum of $400, and the verdict returned was for the single gross sum of $300, thus conclusively demonstrating that the claim so made was very materially in excess of the actual damages. Under the record before us, we must hold that the court erred in directing the jury that a finding for plaintiff would entitle him to a recovery of double damages. We -are also of the opinion that the court should have sustained the defendant’s motion for judgment against it for one half the amount of the verdict returned.
For the reasons stated, the judgment below is reversed and cause remanded for further proceedings in harmony with this opinion. — Reversed and remanded.
