The MicMgan State Police and tbe State accident fund bave appealed from an order *291of the workmen’s compensation commission awarding compensation to John Wesley Moore for partial disability during the period from August 20, 1948, to November 5th of the same year. The sole question they have presented is: “Has the plaintiff met the burden of proof that he has any physical disability or loss of wage earning power due to any condition peculiar to or arising out of his employment which would entitle him to benefits provided by the Michigan workmen’s compensation act?”

Plaintiff was continually employed as a janitor by the Michigan State Police from October, 1923, to August, 1942, and from October, 1944, to May 13, 1948. In the last 2 years of his employment he suffered 4 injuries, 2 of which are the basis of the award. On March 10,1948, he slipped and wrenched his back while lifting a heavy desk in order to place casters under it, and on April 15th, while carrying a heavy scrubbing machine up some stairs, he stumbled and felt pain in the lower part of his back. He continued his regular work until the date of his resignation about a month later.

On August 20,1948, he obtained employment with the Union Telephone Company as a janitor, after being examined by the company physician and certified for light duty only. He worked 8 hours the first day, but his back so pained him and he became so tired from a full day’s work that he worked thereafter for only 4 to 6 hours per day.

The commission found that his injuries arose out of and in the course of his employment and were all promptly reported to his superiors. They further found that the dull pain or ache suffered by him resulted from the 2 injuries mentioned, but that the first evidence of disability was on August 20, 1948, when he became unable to do a full day’s work. They found that his condition was entirely subjective and that he also has mild arthritis of the kind common *292in men of his age, but which was insufficient to explain his complaints. They further stated that they seriously doubted if any of the disability for the injuries remained after November 5, 1948, and that plaintiff had failed to sustain the burden of proving continuation of his disability after that date.

This opinion is restricted to the sole question raised by the defendants. They contend that the commission based its award purely upon speculation, conjecture and surmise, totally unsupported by the evidence; that plaintiff: has not sustained the burden of establishing his claim; that there was no evidence of disability; and that even were evidence of disability introduced, the arthritic condition of plaintiff would have presented equally consistent inferences as to the cause of that disability, thereby barring any award. The award would .have to be set aside were defendants’ contentions correct. Riley v. Kohlenberg, 316 Mich 144. However, a careful consideration of the record leads to the conclusion that while the evidence is not at all strong, there is sufficient competent testimony to sustain the finding that plaintiff was partially disabled from August 20, 1948, until November 5th of the same year as a result of the accidental injuries to his back (CL 1948, § 413.12 [Stat Ann 1949 Cum Supp § 17.186]), though the testimony is clear that after that date any incapacity from that cause had ceased.

The award is affirmed, without costs as appellee filed no brief.
