Opinion by

The injuries for which the plaintiff seeks to recover were *243caused by a collision between the . wagon in which.he was riding and a hansom cab owned by the defendant company and then, being driven by William Alexander. The only negligence alleged or attempted to be proved was that, of the driver, and unless he was acting as the servant or agent of the defendant this judgment cannot be sustained. In an action to recover damages from one person for the negligence of another, upon the principle of respondeat superior, the plaintiff cannot recover, unless it is made to appear that the relation l.of master and servant in fact existed, whereby the negligent act of the servant was legally imputable to the master: Stevens v. Armstrong, 6 N.Y. 435; McCullough v. Shoneman, 105 Pa. 169 ; Fuhrmeister v. Wilson, 163 Pa. 310. Even where the relation of master and servant éxists, the former, is only liable for the acts of the latter done in the course of his employment, and while the question of what is within the course of such employment is usually one for the jury, when the facts are undisputed and it clearly appears that the act of the servant was outside the line of his employment it is the duty of the court so declare: Towanda Coal Co. v. Heeman, 86 Pa. 418; Arzt v. Lit, 198 Pa. 519; Simmons v. Pennsylvania Railroad Co., 199 Pa. 232 ; Guille v. Campbell, 200 Pa. 199.

The owner of property is not responsible ( for the negligence, of a person acting independently, in the. execution: of some undertaking therewith or in connection therewith, when ; the owner does not havé the right, to control arid, does not control the method of execution; Hunt v. Pennsylvania Railroad Co., 51 Pa. 475 ; Harrison v. Collins, 86 Pa. 153 ; Allen v. Willard, 57 Pa. 374; Thomas v. Altoona, etc.; Elec. Railway Cd., 191 Pa. 361; Congregation v. Smith, 163 Pa. 561 ; Hilliard v. Richardson, 69 Mass. 349. The English cases which hold the owner of a public cab liable for the negligence of the driver, who at common law would have been a bailee of the vehicle are all based upon the provisions of the Metropolitan Hackney Carriage Act: Powles v. Hider, 88 Eng. Common Law Rep. 207 ; Fowler v. Lock, L. R. 7 Common Pleas, 272; Venables v. Smith, L. R. (1877); 2 Q. B. Div. 279; Gates v. Bill, L. R. (1902) 2 K. B, 38 ; King v. London Improved Cab Co., L. R. 23. Q. B. Div. 281. The mere ownership of the cab in the present case did not render the defendant company liable; unless The driver was its servant, *244or the manner in which the cab was operated was subject to its control.

Proof of ownership may, under some circumstances, be sufficient to sustain an inference in favor of a third party that a person in charge of property was the agent or servant of the owner: McCoun v. N. Y. Cent., etc., R. R. Co., 66 Barb. 338; Norris v. Kohler, 41 N. Y. 42; Edgeworth v. Wood, 58 N. J. 463 (33 Atl. Rep. 940). The relation of the defendant company and the driver to each other was not, however, in the present case, left to mere inference. The plaintiff called Alexander, the driver, and proved by him that upon the day in question he “ drove hansom No. 60, belonging to the Pennsylvania Railroad Co.” but did not see fit to interrogate him as to how the cab came to be in his possession. Counsel for the defendant exercised their right to cross-examine the witness who testified that he had leased the cab from the defendant company under an agreement in writing which was produced and identified. The plaintiff did not even then see fit to offer tliis written agreement in evidence, but closed his testimony, which established, if it proved anything, that he had been injured through the negligence of a man who had leased a cab from the defendant company. The defendant company subsequently offered, in connection with other evidence, the written agreement under which the cab and two horses were hired to Alexander, and Alexander was recalled as a witness and examined and cross-examined at length. The oral testimony of Alexander disclosed nothing which varied the terms of the written agreement, nor anything which would have warranted a finding that the defendant company exercised any control over the driver with regard to the manner of operating the cab. The agent of the defendant company, under the terms of the written agreement; “ For and in consideration of the sum of four dollars and on the conditions as stated below, hires to William Alexander, driver, hansom No. 60, with two horses, for thirteen hours from 9.15 A. M. of the date stamped on the back of the certificate.”' The conditions embodied in the contract required that the bailee should not use a horse longer than six and one half hours without return to stable for exchange, that he should wear uniform as prescribed, that during the time of the contract he should abstain from the use of all intoxicat*245ing drinks and present a neat and clean appearance, that he should conform strictly to prescribed rates and other regulations, and upon a violation of any of these conditions the bailor might cancel the unexpired term of the agreement. These conditions protected the horses of the bailor from injury by being continuously driven longer than a fixed period of time, rendered possible the easy identification of the bailee through his uniform, tended to keep him in condition fit to have the property in charge and were a check upon extortion from passengers, but they imposed no limitation, and gave the bailor no power to impose a limitation upon the discretion of the bailee as to where he should drive, or the manner in which he should use the property during the time he had the right to use it. He was not required to go'to any particular cab-stand, might take the cab to any part of the city he chose, and whatever fares he took were’his own ; the appellant had no interest in the receipts of the cab. The regulations with which the driver was obliged to conform had no relation to the manner in which he used the hansom or drove the same. It appears in evidence that there was an arrangement among the various drivers that when upon the cab-stand at Broad street station the orders which came through the office there should be filled by the cabs then disengaged which had first come upon the stand, but even there, each driver had the right to pick up any fare which offered. It affirmatively appeared that there were no regulations covering the manner of driving. The learned judge of the court below was clearly right in holding that this contract between the defendant company and Alexander created the relation of bailor and bailee, and not that of master and servant. When he went further, however, and said to the jury: “ Whether or not there was a bailment will depend upon your concluding from the facts of the case that the arrangement of lease was merely a cover; that it was a cover to accomplish the object of exempting the company from responsibility for its driver. ... I leave it to you to say, whether or not it was a cover, and Alexander was really employed by the company defendant as a driver ; ” he fell into error. The motive of the company in determining the conditions of the contracts into which it entered was not material, if it was unwilling to assume the responsibility of an employer of the drivers of *246cabs,.it had a right.to decline to enter into-that relation. The evidence as to the contract was clear and uncontradicted, in the execution thereof there was no evidence, of any departure from its terms in the subsequent dealings of the parties, and no fact was proved which tended to throw doubt upon the good faith*of the contracting parties,.- No fact was proved from which a jury ought to be permitted to infer that the written agreement was a mere cover to conceal some other contract, which constituted the. parties master and servant. All the assignments of error are sustained,.and the judgment is reversed.
