This is an action of tort for personal injuries received on May 17, 1901, by the plaintiff while riding in one of the defendant’s open cars in Boston. The plaintiff’s testimony tended to show that she boarded the car in Dewey Square and as it reached the side door of the South Station some shavings, sawdust and a piece of wood fell from overhead and the sawdust blew into the car and got into her eye causing the injuries complained of. On cross-examination the plaintiff testified that it seemed as though it had been thrown down after the man got through his work, and that the wind carried it into the car, but she did not know whether it was thrown down or whether it blew down, and that the same effect would have been produced if the wind had carried it down. There was a verdict for the plaintiff and the case is here on exceptions by the defendant to the refusal of the judge to rule that on all of the evidence the plaintiff was not entitled to recover.
The exceptions assume that there was an elevated structure belonging to the defendant which ran overhead at the place where the accident occurred, and the plaintiff's contention is that the shavings, sawdust and piece of wood fell in consequence of negligence on the part of the defendant, or its servants or agents while at work or engaged upon the elevated structure.
*574There is nothing to show what caused them to fall. For aught that appears the wind may have blown them down. There was testimony tending to show that at the time the wind was blowing from fourteen to nineteen miles an hour with a maximum velocity of twenty-two miles an hour. The statement of the plaintiff that it seemed as though they had been thrown down was immediately followed by the statement that she did not know whether they were thrown down or blown down, and the effect of her testimony was to leave the cause of the fall entirely uncertain. Aside from the fall of the sawdust, shavings and wood there was not even testimony tending to show that any one was at work on the elevated structure at the place where the accident occurred. The cause of the fall is entirely a matter of conjecture. The plaintiff invokes the doctrine of res ipso loquitur. But that applies only when the circumstances are such as to afford just ground for a reasonable inference that according to ordinary experience the accident would not have occurred except for the want of due care. It was held in the cases relied on by the plaintiff and in others referred to by the defendant that there was ground for such an inference. See Lowner v. New York, New Haven, & Hartford Railroad, 175 Mass. 166; Manning v. West End Street Railway, 166 Mass. 230; Graham v. Badger, 164 Mass. 42; Jager v. Adams, 123 Mass. 26; Kearney v. London, Brighton, & South Coast Railway, L. R. 6 Q. B. 759; Hogan v. Manhattan Railway, 149 N. Y. 23.
But where as in the present case it is as inferable that the accident occurred without negligence on the part of the defendant or its servants or agents as that it did, the ground for such an inference is wanting. If causes, other than the negligence of the defendant or its servants or agents, might have produced the accident, the plaintiff was bound to exclude the operation of such causes by a fair preponderance of the evidence. Kendall v. Boston, 118 Mass. 234. Searles v. Manhattan Railway, 101 N. Y. 661. Wiedmer v. New York Elevated Railroad, 114 N. Y. 462.
It cannot be held that the mere presence of sawdust and shavings and a piece of wood on the elevated structure was of itself evidence of negligence, and. there is nothing to show that if the iron flooring under the tracks had been extended beyond the sides of the tracks the falling of the sawdust would or might have been prevented. Exceptions sustained.
