This is an action of tort to recover compensation for personal injuries received by the plaintiff by being struck by an automobile owned by the defendant. The evidence touching the manner and circumstances of the injury was conflicting and it would seem that the defendant reasonably might have expected a verdict in his favor. But we have nothing to do with the weight of the evidence and are concerned only with the questions of law.
1. There was evidence tending to show that the mother of the plaintiff, having occasion to go out of her home on the afternoon of the injury, left her youngest child, two years *556and eight months of age, and the plaintiff, four years and five months of age, in charge of her niece, then about fifteen years old, who lived with her. The plaintiff then was in the house but was being dressed so that he could go on the street. The niece took these two small children out for a walk, with no definite destination, holding the younger by the hand and permitting the plaintiff to run ahead playing on the sidewalk, and calling him back from time to time. Finally the plaintiff ran quite a distance ahead of her and crossed to the other side of the street, and she called to him when he was from one hundred to two hundred feet away (or further according to some evidence) to come back. As she called, an automobile passed and just then the plaintiff started to cross the street and he was almost over to her side when the automobile knocked him down. The automobile was “ going very fast ” and kept going fast until the plaintiff was knocked down. The street was a country road and automobiles passed back and forth to some extent but not very much. One could see up and down the street for a long distance. It was level. She did not see the automobile until it passed her. There was much evidence tending to show that the accident did not happen in this way, but in the aspect of the evidence most favorable to the plaintiff the narrative just stated might have been found to be true.
The rights of the plaintiff must chiefly be determined by the conduct of his proper custodian. Plainly the jury could find that the mother was not negligent in intrusting the plaintiff to the care of her niece. Although the case is close upon this point, it cannot quite be said as matter of law that the niece in the performance of her duty as temporary custodian of the plaintiff failed to exercise due care. Moreover, the plaintiff, while too young to have much prudence, cannot be pronounced as matter of law incapable of exercising any care in the circumstances confronting him. All these factors required the submission to the jury of the issue of the due care of the plaintiff, his custodian and his mother. Sullivan v. Boston Elevated Railway, 192 Mass. 37. Beale v. Old Colony Street Railway, 196 Mass. 119. Dowd v. Tighue, 209 Mass. 464. Ayers v. Ratshesky, 213 Mass. *557589. Travers v. Boston Elevated Railway, 217 Mass. 188. McCulloch v. Needham, 217 Mass. 227. Tannian v. Amesbury, 219 Mass. 310. Sughrue v. Bay State Street Railway, 230 Mass. 363. Eshenwald v. Suffolk Brewing Co. 241 Mass. 166. Direnski v. Eastern Massachusetts Street Railway, 244 Mass. 313. The case at bar is distinguishable from cases like Holian v. Boston Elevated Railway, 194 Mass. 74, Walukewich v. Boston & Northern Street Railway, 215 Mass. 262, Kelley v. Boston & Northern Street Railway, 223 Mass. 449, Garabedian v. Worcester Consolidated Street Railway, 225 Mass. 65, Gallagher v. Johnson, 237 Mass. 455, and Sullivan v. Chadwick, 236 Mass. 130.
2. There was sufficient evidence of the negligence of the driver of the automobile to require the submission of that issue to the jury. Pertinent evidence in that connection was to the effect that the street was comparatively free from traffic, that it was straight for a considerable distance with unobstructed view, that it was daylight, that the speed of the automobile was variously estimated at from seven to forty miles an hour, that the driver did not see the girl with the two children as he came along the street, that he saw the plaintiff standing in the gutter and did not see him again until after the accident, and that the plaintiff was almost across the street before he was struck, and that the driver of the automobile, who was in it alone, was not licensed to drive a motor vehicle. Quinn v. Boston Elevated Railway, 214 Mass. 306, 310. Sughrue v. Bay State Street Railway, 230 Mass. 363, 366. Fuller v. Andrew, 230 Mass. 139, 147. Walters v. Davis, 237 Mass. 206. McMahon v. Pearlman, 242 Mass. 367, 370.
3. The defendant was building a sewer for the city of Boston in a near by street. Admittedly he was the owner of the automobile but was not in it at the time of the injury. On the point whether at that time it was being used in his business by his authority there was evidence that the driver of the automobile, one Todesca, was in his general employ caring for gasoline pumps and compressors, but was not employed to drive and never had driven his automobile. About half past three o’clock on a November afternoon the defendant instructed Todesca to go to Roslindale to get some *558lanterns, the store to which he was sent being about fifteen minutes walk from the job. No directions were given to take the automobile, which was about seven hundred feet from the place where the defendant gave his orders to Todesca. Never having driven the defendant’s automobile, Todesca took it on this occasion and while he was returning from the store with the lanterns the accident happened. There was also evidence that the defendant said to the father of the plaintiff shortly after the injury, that “ he sent Frank Todesca up for some lanterns; that it was getting dark and he had to get the lanterns in a hurry for a job he was doing for the city of Boston.”
With the exception of the testimony just quoted, all the evidence on that point came from the defendant and a witness called by him. Of course the plaintiff was not bound by it. See Sullivan v. Boston Elevated Railway, 224 Mass. 405. If all this evidence were believed, plainly the automobile was not being used at the time by the defendant’s authority and hence the defendant would not be liable. Manifestly not every act performed by a servant in his master’s business binds the latter. Hartnett v. Gryzmish, 218 Mass. 258. Marsal v. Hickey, 225 Mass. 170. Seaboyer v. Director General of Railroads, 244 Mass. 122. Porcino v. De Stefano, 243 Mass. 398. Phillips v. Gookin, 231 Mass. 250. But it is familiar law that the jury are not bound to give credit to testimony even though uncontradicted. Lindenbaum v. New York, New Haven & Hartford Railroad, 197 Mass. 314, 323. Commonwealth v. Russ, 232 Mass. 58, 70. Mere disbelief of testimony is not proof of facts of an opposite nature or tendency. Wakefield v. American Surety Co. 209 Mass. 173, 177. Martell v. Dorrey, 235 Mass. 35, 41. The jury might have found that the only credible evidence was that which proved that the defendant owned the automobile, that Todesca, who was in the general employ of the defendant, was using it during time when his master was entitled to his services on his master’s business of getting lanterns, and that that business was urgent and must be quickly done by reason of approaching darkness. If these were found to be the facts, then the case stands in this way: there is use of the defendant’s automobile by his *559servant during regular hours of work in the prosecution of his business. We are of the opinion that from these facts the inference might be drawn under the circumstances here disclosed, that such use was impliedly authorized or assented to by the defendant, notwithstanding the denials of the defendant and his servant. Whether such inference ought to be drawn was matter for the jury to determine. The fact that the use of the automobile was in the owner’s business distinguishes the case at bar from cases like O’Rourke v. A-G Co. Inc. 232 Mass. 129, Melchionda v. American Locomotive Co. 229 Mass. 202, Teague v. Martin, 228 Mass. 458, Gardner v. Farnum, 230 Mass. 193, Canavan v. Giblin, 232 Mass. 297, Wilson v. Pennsylvania Railroad, 34 Vroom, 385, and Moquin v. Kalicka, ante, 476.
The case at bar falls within the class of cases illustrated by Reynolds v. Denholm, 213 Mass. 576, D’Addio v. Hinckley Rendering Co. 213 Mass. 465, Hopwood v. Pokrass, 219 Mass. 263, Heywood v. Ogasapian, 224 Mass. 203, Campbell v. Arnold, 219 Mass. 160, Ouimette v. Harris, 219 Mass. 466, Barney v. Magenis, 241 Mass. 268, Conant v. Constantin, 247 Mass. 76.
4. There was no error in the denial of the several requests of the defendant for instructions. Most of them related to fragmentary portions of the evidence with which the judge could not be required to deal specifically. Ayers v. Ratshesky, 213 Mass. 589, 593.
The charge was adequate in its treatment of the question of the due care of the plaintiff. The third prayer omitted all reference to the supervision of the girl in charge of the plaintiff and her relation to his conduct, which was an important factor in determining his due care. The sixteenth request contained statements of fact about which the evidence was conflicting. The trial judge was not obliged to adopt the phrase of the instruction provided the subject was dealt with adequately.
There was no error in the way in which the failure of the driver to be licensed and the bearing of that violation of a criminal statute upon the question of negligence of the defendant or the driver was left in the charge. Berdos v. Tremont & Suffolk Mills, 209 Mass. 489, 496. Davis v. *560John L. Whiting & Son Co. 201 Mass. 91, 96. Nager v. Reid, 240 Mass. 211.
5. The exception to the ruling that it was a violation of law for the defendant to allow his automobile to be driven without a license, if he knew it and knew that the driver had no license, must be overruled. The charge was in accordance with the statute. G. L. c. 90, §§ 12, 20. The judge in his charge cannot rightly assume the existence of facts not proved, or raise false issues, or give instructions not adapted to the evidence. Clough v. Whitcomb, 105 Mass. 482. Plummer v. Boston Elevated Railway, 198 Mass. 499, 516. Corsick v. Boston Elevated Railway, 218 Mass. 144. What has been said already under division 3 of this opinion shows that the inference as to these facts against the defendant might have been drawn. In this connection it is to be noted that there was evidence to the effect that shortly after the accident the defendant said to the father of the plaintiff that Todesca had no license to operate the automobile.
A careful examination of the entire record discloses no reversible error.
Exceptions overruled.
