The undisputed evidence here showed that this claimant, an able-bodied man capable of lifting packages of cheese from the floor onto a table approximately 4 feet in height continuously for 8-lrour periods, amounting to approximately 10,000 pounds per hour for a period of 18 months prior to his disability, suffered a pain in the leg which is a symptom of a ruptured disk. If the lifting caused it, then the lifting which caused the disk to rupture was his accident

Since he did not know when it happened, the fact of his accident may be proved by circumstantial evidence as well as by direct evidence, but to prove it in this manner it is necessary to exclude every other reasonable manner in which it could have occurred other than in the course of the employment, by a preponderance of the evidence and to the satisfaction of the trior of facts, and it must appear to the appellate court that the circumstances shown tend in some appreciable degree to establish the conclusion claimed.

Also, the time of the accident may be shown by circumstantial as well as direct evidence, and in that connection it is incumbent upon the fact-finding tribunal to consider the physical condition of the claimant and his ability to work at heavy lifting prior to the time he felt pain, that the pain he felt is a symptom of a ruptured disk, that he had not felt this pain before a given date, and that soon thereafter the rupture was established by X-ray and myelogram. Taking all of these facts into consideration, it follows that the evidence authorized, but did not demand, a find *276 ing that- the claimant, on or about December 14, 1953, suffered a ruptured disk arising out of and in the course of his employment.
