Patteson, J., before whom the cause was tried, told the jury that the question for them to consider was, whether the fire had been occasioned by gross negligence on the part of the defendant; adding, that he was bound to proceed with such reasonable caution as a prudent man would have exercised under such circumstances.

A verdict having been found for the plaintiff, a rule nisi for a new trial was obtained, on the ground that the jury should have been directed to consider, not whether the defendant had been guilty of a gross negligence with reference to the standard of ordinary prudence, a standard too uncertain to afford any criterion, but whether he had acted bona fide to the best of his judgment; if he had, he ought not to be responsible for the misfortune of not possessing the highest order of intelligence. The action under such circumstances was of the first impression.[[57]]

Talfourd, Serjt., and Whately, showed cause.

The pleas having expressly raised issues on the negligence of the defendant, the learned judge could not do otherwise than leave that question to the jury. The declaration alleges that the defendant knew of the dangerous state of the rick, and yet negligently and improperly allowed it to stand. The plea of not guilty, therefore, puts in issue the scienter, it being of the substance of the issue: Thomas v. Morgan, 2 Cr. M. & R. 496. And the action, though new in specie, is founded on a principle fully established, that a man must so use his own property as not to injure that of others. On the same circuit a defendant was sued a few years ago for burning weeds so near the extremity of his own land as to set fire to and destroy his neighbors’ wood. The plaintiff recovered damages, and no motion was made to set aside the verdict. Then, there were no means of estimating the defendant’s negligence, except by taking as a standard the conduct of a man of ordinary prudence: that has been the rule always laid down, and there is no other that would not be open to much greater uncertainties.

R. V. Richards, in support of the rule.

First, there was no duty imposed on the defendant, as there is on carriers or other bailees, under an implied contract, to be responsible for the exercise of any given degree of prudence: the defendant had a right to place his stack as near to the extremity of his own land as he pleased, Wyatt v. Harrison, 3 B. & Adol. 871: under that right, and subject to no contract, he can only be called on to act bona fide to the best of his judgment; if he has done that, it is a contradiction in terms, to inquire whether or not he has been guilty of gross negligence. At all events what would have been gross negligence ought to be estimated by the faculties of the individual, and not by those of other men. The measure of prudence varies so with the varying faculties of men, that it is impossible to say what is gross negligence with reference to the standard of what is called ordinary prudence. In Crook v. Jadis, 5 B. & Adol. 910, Patteson, J., says, “I never could understand what is meant by parties taking a bill under circumstances which ought to have excited the suspicion of a prudent man;” and Taunton, J., “I cannot estimate the degree of care which a prudent man should take.”...

Tindal, C. J. I agree that this is a case primæ impressionis; but I feel no difficulty in applying to it the principles of law as laid down in other cases of a similar kind. Undoubtedly this is not a case of contract, such as a bailment or the like, where the bailee is responsible in consequence of the remuneration he is to receive: but there is a rule of law which says you must so enjoy your own property as not to injure that of another; and according to that rule the defendant is liable for the consequence of his own neglect: and though the defendant did not himself light the fire, yet mediately he is as much the cause of it as if he had himself put a candle to the rick; for it is well known that hay will ferment and take fire if it be not carefully stacked. It has been decided that if an occupier burns weeds so near the boundary of his own land that damage ensues to the property of his neighbor, he is liable to an action for the amount of injury done, unless the accident were occasioned by a sudden blast which he could not foresee. Turberville v. Stamp, 1 Salk. 13. But put the case of a chemist making experiments with ingredients, singly innocent, but when combined liable to ignite; if he leaves them together, and injury is thereby occasioned to the property of his neighbor, can any one doubt that an action on the case would lie?

It is contended, however, that the learned judge was wrong in leaving this to the jury as a case of gross negligence, and that the question of negligence was so mixed up with reference to what would be the conduct of a man of ordinary prudence that the jury might have thought the latter the rule by which they were to decide; that such a rule would be too uncertain to act upon; and that the question ought to have been whether the defendant had acted honestly and bona fide to the best of his own judgment. That, however, would leave so vague a line as to afford no rule at all, the degree of judgment belonging to each individual being infinitely various: and though it has been urged that the care which a prudent man would take, is not an intelligible proposition as a rule of law, yet such has always been the rule adopted in cases of bailment, as laid down in Coggs v. Bernard, 2 Ld. Raym. 909. Though in some cases a greater degree of care is exacted than in others, yet in “the second sort of bailment, viz., commodatum or lending gratis, the borrower is bound to the strictest care and diligence to keep the goods so as to restore them back again to the lender; because the bailee has a benefit by the use of them, so as if the bailee be guilty of the least neglect he will be answerable; as if a man should lend another a horse to go westward, or for a month; if the bailee put this horse in his stable, and he were stolen from thence, the bailee shall not be answerable for him; but if he or his servant leave the house or stable doors open, and the thieves take the opportunity of that, and steal the horse, he will be chargeable, because the neglect gave the thieves the occasion to steal the horse.” The care taken by a prudent man has always been the rule laid down; and as to the supposed difficulty of applying it, a jury has always been able to say, whether, taking that rule as their guide, there has been negligence on the occasion in question.

Instead, therefore, of saying that the liability for negligence should be co-extensive with the judgment of each individual, which would be as variable as the length of the foot of each individual, we ought rather to adhere to the rule, which requires in all cases a regard to caution such as a man of ordinary prudence would observe.[[58]] That was in substance the criterion presented to the jury in this case, and therefore the present rule must be discharged.
