The court erred in refusing tbe second instruction asked by tbe plaintiffs. Tbe idea in tbe mind of tbe court evidently was, tbat tbe plaintiffs were bound to exercise extraordinary care, or use tbe highest degree of diligence, or they could not recover — tbat slight negligence on tbeir part would defeat tbe action. This appears from tbe language of tbe instruction wbicb immediately followed, and is given as second, and is set forth in tbe reporter’s statement of tbe case.
Tbe rule of law is, not tbat slight negligence on tbe part of tbe plaintiff will prevent a recovery in such cases, but it is, as stated in tbe request to instruct wbicb was refused, tbat it is only tbe want of ordinary care and prudence, under tbe circumstances, to avoid tbe injury, wbicb tbe law imputes to tbe plaintiff as a fault contributing to it, and wbicb will bar bis remedy or right to recover damages on account of it. This question was fully discussed by Mr. Justice PAINE, in Dreher v. the Town of Fitchburg, 22 Wis., 675, where tbe very point was presented. And such is tbe rule of law, we believe, in every court where tbe doctrine of tbe different degrees of negligence, as slight, prdinary, and gross, is maintained as we think tbat doctrine generally is. Story on Bailments, §§ 11 to 17 and cases cited. Shearman andRedfield on negligence, §§ 16,17,18; tbe same, §§ 29, 23, and authorities cited. It seems unnecessary after tbe able and thorough examination wbicb tbe question received in Dreher v. the Town of Fitchburg, to extend our remarks upon it here, or upon tbe impropriety of refusing to give tbe instruction wbicb was asked. Slight negligence is there defined in almost tbe precise words in wbicb it was defined by tbe court below, in tbe instruction here given, and it was there held not to be error to refuse an instruction tbat slight negligence on tbe part of tbe plaintiff would defeat tbe action. It was distinctly said tbat such was not tbe law, but only tbat ordinary negligence, wbicb is tbe want of ordinary care, or of tbat degree of diligence wbicb men in general exert in respect to tbeir own concerns, would have tbat effect. No extraordinary forecast or pru*149dence, nor such, care as very prudent and cautious men would observe, is required in order to shield the plaintiff from the imputation of being the author of his own injury, it being otherwise shown to have proceeded from the wrongful or negligent act or omission of the defendant.
Ordinary care and prudence only are required for that purpose. Of course, what may constitute ordinary care under some circumstances, may not under others. This varies and is materially affected by the nature, situation, bulk, and value of the article or thing to be cared for, and by other facts and circumstances. Speaking upon this point in connection with the duties of bailees and their liability for the loss or destruction of property entrusted to their care, Judge STORY says : “Aman would not be expected to take the same care of a bag of oats, as of a bag of gold; abale of cotton, as a box' of diamonds, or other jewelry; of a load of common wood, as of a box of rare paintings; of a rude block of marble, as of an exquisitely sculptured statue. The value especially, -is an important ingredient to be taken into consideration upon every question of negligence; for that may be gross negligence in the care of a parcel of extraordinary value, which in a common parcel would not be so.” Story on Bailments, § 15, and see also § 186. And the author's of the treatise on the Law of negligence, § 23, observe: “We have said that in estimating the degree of care which it is incumbent upon any person to use, the situation of such person, rather than the subject of his care,' is to be taken into account. But in determining what amounts to. any specified degree of care in each particular case, the thing to be taken care of, and the danger to which it is exposed, are the chief considerations. Thus, the same person may at the same time be entrusted with the charge of coals, books and diamonds, and be bound to no more than ordinary care in respect to any of them, yet the amount of thought, attention and pains which he would be required to bestow upon them respectively, would greatly differ. He would fully discharge his duty by putting the coal *150in bis bin, and in many parts of the country, would not need to lock it up; while it would generally be his duty to put the books in a good room, and the diamonds in some secret place, keeping a careful watch over them.
It is manifest from these considerations, that there may be and frequently are, situations and circumstances where the party bound to use only ordinary care would be required to be equally and even more watchful and attentive, and to take the same or greater pains and trouble to guard against injury, than would be necessary to constitute great care or great diligence in other situations and circumstances, where the latter is the degree of care and diligence demanded by law. The amount or kind of vigilance and caution requisite in each of the three degrees of care recognized by law, as slight, ordinary and great, is relative and governed by the circumstances of the particular case; and it is obvious that greater vigilance and caution may be needful in the exercise of ordinary care in some cases, than is required to constitute what is termed in the law great care in others. A person bound to only ordinary care of jewels or diamonds would be required to bestow more attention and exercise greater vigilance and caution than one bound to great care of wood or coal, or other such articles; but, notwithstanding, these differences arising from the nature or situation of the thing to be cared for, the degrees of care as defined by law, and which depend on the peculiar relations existing between the parties and the obligations arising therefrom, are not to be lost sight of or disregarded. A person charged with but ordinary care of a jewel or other article of great value, is not on account of the increased attention and watchfulness required, because of its value and of the necessity of guarding against theft or other loss, to be held to the use of extraordinary prudence and foresight, or of such care as persons of that character are accustomed to use, and the omission of which, constitutes slight negligence. He is not to be held responsible for losses happening from slight negligence or the want of great care, but only for those resulting from his *151omission to use ordinary care according to tbe circumstances of tbe particular case.
In tbe present case, tbe situation of tbe plaintiff's warehouse, tbe materials and mode of its construction, tbe purposes for wbicb it was used, its proximity to tbe railway track, and all circumstances enhancing tbe danger and risk of destruction from fire communicated by sparks from tbe locomotives wbicb were constantly passing and repassing, may have been such as to have required great prudence and foresight on tbe part of tbe plaintiffs to prevent its taking fire from such cause, but still they were not required to exercise any greater prudence and foresight than persons of ordinary care or men of business and beads of families usually exhibit in their own affairs, or than such persons usually exhibit or would be expected to exhibit and use under tbe same or like circumstances. Tbe latter is no doubt tbe true measure of tbe care wbicb was required of tbe plaintiffs, and they were not required to exercise that degree of it indicaied by tbe instruction wbicb was given, namely, “ such care as persons of extraordinary prudence and foresight are accustomed to use.” It was error, therefore, to refuse tbe instruction wbicb was asked, and for this tbe judgment must be reversed.
A single further observation appears to be necessary in order to correct an inaccuracy of expression found in Potter v. The Chicago and Northwestern Railway Co., 21 Wis., 377, and wbicb seems most likely to have led to tbe error here complained of. Tbe closing sentence of tbe opinion in that case'reads thus: “Negligence, proximate or contributing to tbe injury, however slight, prevents recovery.” If by this is understood, as was doubtless intended, any neglect or omission, however slight, to use ordinary care, or a slight want of such care, contributing to tbe injury, the expression is quite right and no correction is required. But tbe language is not adapted to conveying this idea with accuracy. It is susceptible of a different construction, and that slight negligence .as tbe lowest of tbe three de*152grees defined by law will defeat tbe action, wiicb is incorrect. All this is explained in Dreher v. The Town of Fitchburg, pp. 677, 678, where it is said that the law does not attempt to measure how little or how greatly the plaintiff may have fallen short of using ordinary care, but that any failure in this respect or a slight want of such care, contributing directly to the injury, will forbid a recovery.
By the Court. — Judgment reversed, and a venire de novo awarded.
