By • the giving way of a bracket supporting' the staging where the plaintiff was at work shingling the roof of a house under construction by the defendants, he was thrown to the ground suffering personal injuries for which he seeks damages. A verdict having been ordered for the defendants, the case is here on exceptions to the exclusion of evidence.
The plaintiff not having been in their employment, the seventh is the only count stating a cause of action, and the offers of proof having been properly made were sufficient if admitted in evidence to send the case to the jury on the questions of the plaintiff’s due care, the assumption of the risk duly pleaded in the answer, and whether the bracket was a reasonably safe appliance. Cahill v. Phelps, 198 Mass. 332. Noyes v. Boston & Maine Railroad, 213 Mass. 9. Coughlin v. Boston Tow-Boat Co. 151 Mass. 92. Feneff v. Boston & Maine Railroad, 196 Mass. 575. Feeney v. York Manuf. Co. 189 Mass. 336. Donahue v. C. H. Buck & Co. 197 Mass. 550, 552, 553. Jellow v. Fore River Ship Building Co. 201 Mass. 464, 467. Crimmings v. Booth, 202 Mass. 17, 23.
But the plaintiff must show as alleged, that the defendants had assumed the duty of furnishing suitable brackets. Wherever the duty of providing appliances or materials to the injured workman is undertaken this obligation arises, even if no contractual relation exists between the parties. Stewart v. Harvard College, 12 Allen, 58. Mulchey v. Methodist Religious Society, 125 Mass. 487. D’Almeida v. Boston & Maine Railroad, 209 Mass. 81, 87, 88. Coughtry v. Globe Woolen Co. 56 N. Y. 124.
Upon the evidence and offers of proof which were excluded, the jury under appropriate instructions would have been justified in imposing this liability. The plaintiff’s employers by their contract with the defendants were “to perform and furnish all the carpenter work, except, smoothing the floors.” This agreement, even if the carpenters were to bring their tools ordinarily used, did not of itself preclude the plaintiff from showing that the defendants undertook to provide the stagings used in shingling the roof., Earnshaw v. Whittemore, 194 Mass. 187, 191.
It appears that in the development of land owned by them, of which the lot in evidence was a part, the defendants caused plans *143to be prepared. The building operations, however, according to the testimony of the defendant Bates, called as a witness by the plaintiff, had been entrusted to one Graves, with full authority to order lumber and materials, and to superintend the work. The plaintiff thereupon offered to show that the brackets and materials for the staging were supplied by Graves, but, upon the ground that no express authority had been shown, the evidence was ruled inadmissible until a proper foundation had been laid. Plainly the plaintiff was not limited in his proof as to the scope of the agency by the evidence of this witness, or bound to accept his statements as absolutely true.* If the order of proof is within the discretion of the presiding judge, as it certainly is, this ruling was adhered to, although the plaintiff repeatedly renewed the offer until the trial closed. No contract in writing between the principals and their agent existed, and the scope of the agency could be proved by any relevant testimony. “Limitations as between the principal and agent of an apparently general authority, not brought to the knowledge of third persons, do not affect the rights of the latter.” Brooks v. Shaw, 197 Mass. 376, 380. Lloyd v. Grace, [1912] A. C. 716, 736,737. The use by the defendants of the brackets and materials for the staging in the erection of their houses, the fact that they were not owned or hired by the contractors, and apparently had been brought to the premises by Graves acting in the course of his employment, were for the consideration of the jury in connection with the evidence of Bates, and the contract for the carpentry. Bragg v. Boston & Worcester Railroad, 9 Allen, 54. McNeil v. Boston Chamber of Commerce, 154 Mass. 277, 285, 286. Rice v. James, 193 Mass. 458, 463. Brooks v. Shaw, 197 Mass. 376. Larivee v. A’Hearn, 207 Mass. 288.
The plaintiff’s offer of' proof furthermore showed, that on the day of the accident the screw brackets provided by the contractors were all in use, and the jury could find that resort to the “small shingle brackets” furnished by Graves had become necessary or the work might be delayed. Apart from his ostensible powers, the plaintiff also had the right to have the jury determine whether in view of all the circumstances a mutual understanding did not *144exist between bis principals and himself, that under his authority as general manager Graves could do whatever in his judgment he deemed reasonably requisite for the construction of the buildings in accordance with the plans, and if needed could supply materials or appliances to be used for stagings, even if they might not have been owned by his principals but were in their possession and control. Taft v. Baker, 100 Mass. 68. Amory v. Kannoffsky, 117 Mass. 351, 353.
It could not be ruled as matter of law, that no authority to represent the defendants had been shown, and evidence of conversations with him relating to these appliances accordingly was competent. It should have been admitted and the jury instructed, that unless upon the evidence independently of the agent’s admissions they found that he had been empowered to act as the plaintiff contended, the defendants would not be bound. Carberry v. Farnsworth, 177 Mass. 398, 401, 402.
We are of opinion for these reasons, that on the face of the record there was a mistrial, and the exceptions must be sustained.
So ordered.
Bates testified in cross-examination that he never had authorized Graves to furnish any appliances or equipment for the building while the contract between the defendants and Landry and Ouilette was in force.
