*726 T. BAILEY LEE, J.

This is an action for damages. Appellants plead that on or about June 15, 1925, they, being the owners of a certain barge, derrick, pile-driver and equipment of the value of $7,475, hired and bailed the same at an agreed rental to the defendant highway district, the defendant agreeing as part of the consideration to return the property so bailed in as good condition, ordinary wear and tear excepted, as the same was in when delivered; that defendant “did not exercise reasonable diligence to protect *727 and safeguard” said property while in its possession, and “was guilty of such negligence in dealing with said property while in its possession and control .... as to cause” it to be “greatly damaged and almost wholly destroyed by fire” to plaintiffs’ damage in the sum of $3,985.77. At the close of plaintiffs’ case defendant moved for nonsuit urging that plaintiffs had failed to prove a bailment or any act or omission of defendant which would constitute negligence. The motion was sustained and judgment of dismissal entered. A subsequent motion for new trial was denied; and an appeal was taken from both the judgment and the order overruling said motion.

It may be observed at the outset that the court properly overruled appellants’ motion for new trial. A motion for nonsuit presents only a question of law; and, if it is granted and a judgment of dismissal is entered, it is error to grant a new trial. (Tucker v. Hypotheek Min. & Mill. Co., 31 Ida. 466, 173 Pac. 749.)

Appellants primarily attack the court’s action in sustaining respondent’s motion for nonsuit, insisting that there was evidence of both a bailment and negligence. We think the testimony clearly established a bailment. While it is true that plaintiff, A. B. Carscallen; engaged the first crew, including an engineer, and for some eleven days directed the immediate operation of the property, it appears that he engaged the crew at respondent’s instance; that his own wages as well as those of the crew were paid by respondent ; that he quit* the job and left the property after being advised by respondent’s foreman that his services were no longer needed; that the property remained in charge of such foreman and was operated off and on for a period of some ten days by a changing crew employed and directed by him until it was burned on July 7th.

The question of negligence presents more difficulty. Ordinarily, where property is injured, lost or destroyed while in possession of a bailee, a presumption of negligence arises, making a prima facie case and casting upon the bailee the burden of showing that the loss was due to other *728 causes consistent with due care on his part. (Cluer v. Leahy, ante, p. 320, 256 Pac. 760.) But, when it appears that the loss or injury was caused by fire or other extraordinary intervention, the burden is upon the bailor to prove a lack of ordinary care or violation of some specific duty by the bailee resulting in the proximate cause of the damage. (6 C. J. 1158, 1159; Rosendahl v. Lemhi Valley Bank, 43 Ida. 273, 251 Pac. 293; Southern R. Co. v. Prescott, 240 U. S. 632, 36 Sup. Ct. 469, 60 L. ed. 836; Levi v. Missouri K. & T. Ry. Co., 157 Mo. App. 536, 138 S. W. 699; Wilson v. Southern Pac. R. R. Co., 62 Cal. 164; Stone v. Case, 34 Okl. 5, 124 Pac. 960, 43 L. R. A., N. S., 1168; Scott v. Columbia Compress Co., 157 Ark. 521, 249 S. W. 13; Stewart v. Stone, 127 N. Y. 500, 28 N. E. 595, 14 L. R. A. 215; Belt R. & S. Co. v. McClain, 58 Ind. App. 171, 106 N. E. 742; Perera v. Panama-Pacific I. E. Co., 179 Cal. 63, 175 Pac. 454.)

The complaint charged no specific act of negligence, unless it can be said that the general allegation that defendant “did not exercise reasonable diligence to protect and safeguard” constitutes a specific charge. Not until the evidence began to develop could respondent have been apprised of any particular delinquency relied on. The record shows that the barge equipped with engines and boilers was lashed to a public bridge over which vehicles and pedestrians were customarily passing; that it was built of lumber and “dry as a bone”; that the weather was hot and rainless; that the plaintiff, A. B. Carscallen, had advised respondent’s foreman and the engineer in charge that the barge should have a watchman or, if they did not have a watchman and there was danger of fire from “people going down there, and throwing cigarettes out there,” “they should sweep it out clean and soak it down every night with water”; that for three days preceding the burning the suggested precautions had not been observed.

Upon this evidence, appellants insist they should have been permitted to go to the jury. There is nothing in the record descriptive of the fire or the place or manner of its *729 starting. There is nothing to suggest the actual passing or presence of smokers, or that the fire was accidental instead of incendiary. To have reached a verdict for appellants, the jury would have had to exclude all possibility of incendiarism, defective fire-boxes, and overheated connections on the barge itself, and assume that some traveler or chance visitor dropped a lighted match, cigarette or other inflammable substance that caused the ignition. The resulting verdict could have been arrived at only through an indulgence of mere conjecture.

The remaining errors submitted have to do with the admission of evidence over appellants’ objection, but are either too general for consideration or have been cured by other evidence later adduced by appellants.

Judgment and order affirmed. Costs to respondent.
