This is аn action in tort against the defendant Jenny Manufacturing Company and its employee John Connolly brought as a result of a fire loss which the plaintiff alleged was caused by the negligence of John Connolly in delivering gasoline to the plaintiff’s gasoline station. At the close of the plaintiff’s case the defendants rested without offering any evidence and moved for directed verdicts which were denied. The jury returned verdicts for the plaintiff against each defendant. The judge took the verdicts under leave reserved to enter verdicts for the defendants. The defendants then moved for entry of verdicts in their favor and the case is here solely on the plaintiff’s exceptions to the judge’s allowance of this motion. The issue is whether on the evidence most favorable to the plaintiff the jury could determine that the defendants’ negligenсe was the proximate cause of the plaintiff’s damages. We believe that such a determination was warranted.
The evidence pertinent to this issue is summarized. On or about September 27, 1962, a gasoline station, owned by the plaintiff, was damaged by fire. Shortly before the fire started, John Connolly, an employee of the Jenny Manufacturing Company, drove a Jenny truck to the station to deliver gasoline. Connolly connected a hose from the truck to the plaintiff’s underground storage tank. The nozzle of the hose, which lacked a safety valve, was about two inches in diameter and the opening in the tank into which he inserted it was about three inches in diameter. The connection was not an air tight *326 type of connection, although the truck was equipped with a three-inch air tight nozzle from which fumes could not escape.
Therе was evidence that Connolly had started pumping the gasoline from the truck to the storage tank and that for about two minutes prior to an explosion he was talking to the plaintiff, facing away from the truck, about twenty-two feet from the valves that controlled the pumping. Connоlly testified that he had seen two young boys coming up to the side of the truck at that time. After Connolly heard the explosion he came round the corner of the truck and saw that everything was on fire including the truck, the hose and the station. He testified that the truck was equipped with a manual safety switch that shuts off the flow of gasoline into the hose and that after the fire started he severed the connection between the hose and the storage tank spilling some gasoline.
The plaintiff testified that he had nothing to do with the unloading of the gasoline and that Connоlly was talking with him when the fire started. In cross-examination he admitted that he had signed releases on insurance claim forms stating that the fire was caused by two unknown boys tossing a match into the valve control but added, “That was the rumor. There were rumors around.” On redirect examination the рlaintiff admitted that he did not see anyone throw a match into the valve control. There was no other evidence from anyone that matches were thrown into the valve control. 1
The defendants argue that the plaintiff is bound by his own “undisputed” testimony that the fire was caused by two bоys throwing a match into the control valve. The short answer is that this evidence
was
disputed and
*327
in fact rejected by the plaintiff on the basis that he was only relating a rumor. The defendants lean heavily on the case of
Muir Bros. Co.
v.
Sawyer Constr. Co.
In order to warrant the plaintiff’s jury verdicts there must be “sufficient evidence (1) to warrant a finding of negligence on the . . . [defendants’] part, and (2) to warrant a finding that there was a сausal connection between such negligence, if found, and the plaintiff’s injuries.”
Berardi
v.
Menicks,
1. There was sufficient evidence from which the jury could have concluded that the defendants were negligent. Ordinarily the question of negligence is one of fact for the jury. Only when no rational view of the еvidence warrants a finding that the defendant was- negligent may the issue be taken from the jury.
Luz v. Stop & Shop, Inc. of Peabody,
We believe that the pumping of gasoline (a substance which, without careful and proper handling, can be dangerous
2
) from the truck to the tank through a two-inch nozzlе, without a safety valve, into a three-inch aperture (when the truck was equipped with a three-inch air tight nozzle) for a period of two minutes, unattended and without direct observation and supervision by Connolly, presented sufficient evidence from which the jury could reasonably infer that Connolly’s delivery of the gaso
*328
line was negligent.

Stewart
v.
Roy Bros. Inc.
There was sufficient evidence from- which the jury сould have concluded that the defendants’ negligence caused the plaintiff’s damage. The lack of evidence as to the precise factor causing the explosion and fire did not preclude the jury from reaching verdicts for the plaintiff. It is true that the mere cоexistence of the defendants’ negligence and the plaintiff’s injury does not entitle the plaintiff to recovery.
Sullivan
v.
Hamacher,
We believe thаt from the evidence presented the jury could draw the rational inference that the plaintiff’s damage was more likely to have been caused by the negligent gasoline pumping operation than by a cause for which the defendants were not responsible. The mere existence of other possible causes did not preclude the jury from finding that the defendants’ negligence was the proximate cause of the plaintiff’s damage. The plaintiff is not required “to point out the exact way in which the accident occurred as long as . . . [he] shоwed a greater likelihood that . . . [his] injuries came from an act of negligence for which the . . . [defendants were] responsible.”
Purdy
v.
R. A. McWhirr Co.
2. Apart from any direct evidence of negligence, we believe that the jury, from the evidence and from their own common knowledge, could reаsonably have inferred that a fire of unexplained origin would not ordinarily have started without the existence of some negligence on the part of the person who was in sole control of the operation and the equipment. See
Ryan
v.
Fall River Iron Works Co.
In the circumstances of this case, we believe that the jury were warranted in concluding that the explosion and the fire were caused by the defendants’ negligence. Such a conclusion was not required but it was permissible. Permitting the jury to reach such a conclusion “does no more than recognize that
negligence and causation, like other facts, may be established by circumstantial evidence”
(emphasis added).
Evangelio
v.
Metropolitan Bottling Co. Inc.
The defendants argue that the jury werе not permitted to infer negligence and causation from the occurrence of the explosion because “the facts as to the origin of the fire are known.” Even if we assume this to be a decisive factor, the short answer to this argument is that there was no direct evidence as to what caused the explosion. It is true that in cross-examination the plaintiff testified that he had signed insurance releases which contained statements that the fire was caused by “two unknown boys tossing a match into a valve control.” 4 He also testified, however, thаt he had not seen anyone throw a match and that the story of the two boys was a “rumor.” The jury were not required to believe the “rumor” that the fire was caused by two boys and were warranted in disbelieving this evidence. The verdicts returned by the *331 jury indicated that they rejected this evidencе with the result that the direct cause of the fire remained unexplained.
The defendants also maintain that the inference of causative negligence is not permissible because the gasoline tank was not under their control. -It is true that the inference of negligence and causation from the circumstances of the instant case depends upon the defendants’ control of the instrumentalities causing the accident.
McNamara
v.
Boston & Maine R.R.
The defendants have misplaced reliance on
Bristol Wholesale Grocery Co. Inc.
v.
Municipal Lighting Plant Commn. of Taunton,
Prosser defines the element of control necessary to permit the jury to infer negligence and causation from the occurrence of an unexрlained event. “ ‘Control,’ if it is not to be pernicious and misleading, must be a very flexible term. It must be enough that the defendant has the right or power of control, and the opportunity to exercise it . . ..” Prosser, Torts (4th ed.) § 39, at p. 220. See Wigmore, Evidence (3d ed.) § 2509. It is clear Connolly had the right to control the truck and the hose at all times and there was evidence that he had *332 control of the truck, the hose and the storage tank during the pumping procedure. Although the gasoline was being delivered into the plaintiff’s storage tank, it could be found that, at the time of the explоsion, Connolly had exclusive control of the instrumentalities causing the fire.
We believe, therefore, that the evidence relating to the defendants’ control of the instrumentalities causing the accident was sufficient to warrant a finding of the element of control necessаry to permit the jury to reach verdicts for the plaintiff. See
Ybarra
v.
Spangard,
The plaintiff’s exceptions are sustained and judgments are to be entered on the verdicts returned by the jury..
So ordered.
Notes
The releases were offered in evidence as exhibits by the defendants and are before us. They are in the usuаl printed form with typewritten information inserted. After the printed words “loss or damage by reason of” appear the typewritten words, “fire - unknown boy tossed lighted match into valve control panel - gasoline vapors igniting.” The plaintiff signed these form releases to obtain some рayments from the named fire insurance companies.
Geraci
v.
A. G. Tomasello & Son, Inc.
The jury may have reasoned that if Connolly had remained close to the valve controls he would have been in a position to prevent the fire or to control its spread. Moreover, the choice' of еquipment in pumping1 the gasoline from the truck to the storage tank, and Connolly’s inattention during the process, warranted a jury finding of lack of due care on Connolly’s part, not only in preventing the fire but also in preventing its spread to the plaintiff’s • station.
The releases were introduced in evidence by the defendants during cross-examination of the plaintiff. The defendants offered no other evidence.
