The question involved in the present cause, has been before this court in various forms, and the principle that fixes the liability of the defendant, has been several times decided.' In the case of Defrance v. Spencer, 2 *507G-. Green, 462, it was held, that when from good motives, and under prudential circumstances, a person sets out fire, and uses such care and diligence to prevent it from spread-, ing, as a man of ordinary caution would use to prevent it from injuring his own property, he is not liable for the damage it may do to the property of others.
In Hanlon v. Ingram, 1 Iowa, 108, it Avas held, that granting the party the right to set out the fire, it was his duty so to set it out and control it, that it shall not injure the property of his neighbor. He must use his best efforts, and all reasonable diligence, to prevent any injury. Even if set out under prudential circumstances, it is still incumbent on him to guard against its spreading to his neighbor’s premises, by all reasonable efforts. Such being his duty, if he is guilty of negligence, he is liable for the consequences. The same case was again before this court, at the June term, 1856, at Avhich time the decision in Defrance v. Spencer, was adhered to. The court say, (8 Iowa, 84,) that if the circumstances disclose with reasonable certainty, that in setting out the fire and preventing its escape, the defendant has not used those precautionary measures, which a prudent and cautious man would use with reference to his own property, they should hold him liable.
The principles governing the causes above 'cited, are decisive of the only question arising in the present oüe. The instruction was obviously erroneous. If the defendant willfully, carelessly or negligently set out fire, and it escaped into and consumed the plaintiff’s property, he .is liable for the damages resulting from his act. It is not necessary in order to fix his liability, that the act should have been done with intent to injure the plaintiff.
Judgment reversed.
