Jeremiah Murphy, the employee, on Friday, September 24, 1915, received a “slight scratch or break on the tip of the elbow” but" “did not think it was severe enough to amount to anything.” He worked the following day. Sunday he saw a physician who treated him three times. Wednesday, September 29, 1915, his arm was badly swollen and “pus was exuding from the *62elbow.” He then consulted another physician and was advised to notify the Industrial Accident Board. On this day he went to the office of his employer and told the foreman of the injury. No notice in writing of the time, place and cause of the injury, as required by §§15 and 16, Part II, of the workmen’s compensation act (St. 1911, c. 751) was given. Compensation from October 8, 1915, to November 11, 1915, was awarded.
The arbitration committee found that the employer had knowledge of the injury within the meaning of Part II, § 18, of the act, which provides that “Want of notice shall not be a bar to proceedings «under this act, if it be shown that the association, subscriber, or agent had knowledge of the injury.” On appeal the Industrial Accident Board awarded the employee compensation and in its decision stated that the “insurer has raised the question of the giving of notice ’as soon as practicable after the occurrence of the injury.’ . . . The board believe that, in a case of this character, where there is no doubt as to the occurrence of the injury and the employee, despite his lack of education, impresses the committee with his evident sincerity and his truthfulness with regard to the conveying of notice to his foreman as the agent of his employer, that the rights of the claimant should not be defeated by the setting up of the technical point that notice was not given as soon as practicable after the occurrence of the injury.”
Notice in writing must be given by the employee before he can recover under the act, and the necessity of such a notice is not a mere technicality, — it is essential to his rights. Doubtless the Legislature could have dispensed with this condition or could have insisted on a mere oral notice, but it has not done so. The statute expressly requires a written notice. The giving of such a notice is a part of the employee’s case and the burden of proof rests upon him; it is not a matter of defence resting on the employer or insurer. In no case can the injured workman recover compensation, unless such a notice is given within the time required, except where the employer or insurer had knowledge of the injury. Knowledge may dispense with the necessity of notice, but the statutory notice and the “knowledge” are not one and the same thing. While information given orally under some circumstances may be sufficient to establish knowledge and permit recovery, an *63oral notice does not fulfil the requirements of the statute directing that in all cases the notice must be in writing; the oral notice does not take the place of the written notice, nor is such an oral notice necessarily the equivalent of the knowledge of the injury which excuses the written notice. Since no notice was given by the employee, and because the board apparently considered this question as one of defence and did not distinguish between knowledge on the part of the employer and the notice required by the statute, the decree must be reversed.
The case should be sent back to the board for a further hearing as there was sufficient evidence upon which a finding could have been made that the employer had knowledge of the injury.
While the notice must be given as soon as practicable after the occurrence of the injury, no time is specified within which knowledge must be received in order to give the employee compensation. In many employments when an injury is received, especially if it is at all serious, the employer or his agent generally has knowledge of it at the time.
In the case at bar the employee, when injured, was not working at the usual place of business of his employer. He was engaged in repairing a boiler in the greenhouse of one Higgins; and he was alone at the time. An employer may have such knowlege of an injury to one of his employees as to excuse the giving of a written notice, although the injury did not occur on his premises and although he did not know of the occurrence at the time, if he receives proper information which amounts to knowledge, within the time within which the written notice, if one had been given, must have been given by the employee or other person authorized to give the same.
The wound when received appeared to be comparatively insignificant. The employee was ignorant, at first, that the septic condition was caused by the blow on the elbow. As soon as he understood its nature, five days after the injury, he went to the employer’s office and informed the foreman of the facts. He was there in person and doubtless his injury was open to inspection. On all the evidence a finding would have been warranted that the employer had knowledge of the injury within the time required, and was not prejudiced by the delay.
It also is contended by the insurer that Reardon, the foreman, *64whom the employee informed of his injury, was not an agent authorized to receive such information. Reardon was the foreman in the employer’s construction department. Murphy worked under him and received orders and instructions from him. The proper management of the employee’s work was in the care of Reardon, who represented the employer; for this purpose he was its agent, and his knowledge was the knowledge of the employer. Bloom’s Case, 222 Mass. 434. McLean’s Case, 223 Mass. 342. Carroll’s Case, 225 Mass. 203.
The decree is reversed and the case recommitted to the Industrial Accident Board for further hearing on the question whether the employer had knowledge of the employee’s injuries within Part II, § 18, of the act. At such hearing additional evidence may be introduced by both parties.
So ordered.
