— The defendant asked the court to instruct the jury as follows:
“ If you find from the evidence that the defendant’s fence, with the exception of one or two small gaps, was sufficient to
“2. If you find that the plaintiff could, by the use of ordinary care, have prevented the horses and cattle from eating and destroying his hay and corn, he cannot recover for such hay and corn thus destroyed, which by ordinary diligence he might have prevented. The plaintiff, after he knew the horses and cattle of others were destroying his hay and corn, should have used reasonable caution'to have prevented further injury, such as fencing his stacks, and fencing his corn beyond the reach of such stock, provided he could reasonably have done so.”
“3. A man has no right to carelessly look on at the destruction of his property. It is his duty to use reasonable care to prevent such destruction; and if .he fails to use ordinary care, he cannot recover for the injury which by ordinary care he might have prevented.”
l tbespass • cattie^negl ligenee. These instructions were all refused, and defendant excepted. Appellee does not insist that these instructions do not con-ta^n correc1; legal propositions. See Shearman & Redfield on Negligence, § 598; Mather v. Butler County, 28 Iowa, 253; Simpson v. The City of Keokuk, 34 Iowa, 568, and cases cited. It is claimed that the.instructions were not applicable to the facts shown, and that moderate expense and ordinary effort would not have been sufficient to prevent the damage. If it had been proved, as appellee assumes, that the gaps were each ten rods wide, and that there was no material on the ground with which to close them, we might feel compelled to adopt his views. But proof of a fact, and the production of evidence tending to show a fact, are quite different things.
The bill of exceptions recites that there was evidence tending to show that there were one or two small gaps in the partition fence, which it would have required but a short time
II. The defendant also assigns error upon the giving of the following instruction:
“ If, therefore, you are satisfied by a preponderance of the evidence that defendant’s stock did trespass on plaintiffs’s premises as claimed, you will allow plaintiff the actual damages which in your judgment he sustained by reason thereof, without inquiring into the question whether plaintiff’s premises were or not surrounded by a lawful fence.”
2. — —:——: damages . This instruction is'based upon the provisions of chapter 26, Laws of 1870, and an application to it of the doctrines of Weir v. Crane, December Term, 1873. There is no essential difference in the mode in which this statute was enacted and directed to be submitted to vote, from that pursued in Chapter 144 of the Laws of 1868, construed in Weir v. Crane, and following that decision the act of 1870 must be considered in force without submission to vote in a county. The act clearly makes the owner of trespassing stock liable for, damages committed, without inquiry as to whether the premises trespassed upon are inclosed with fences. If it does not do so, it works no change in the existing law.
4. pleading : evidence. It is claimed, however, that this instruction authorizes an entire departure from the pleadings, inasmuch as plaintiff a^eges that his premises were lawfully enclosed, But § 2729 of the Code, which is a substitute for § 2966 of the Revision, provides that a party shall not be compelled to prove more than is necessary to entitle him to the relief asked for, or any lower degree included therein.
