delivered the opinion of the court:
Henry Knaak died on December 6, 1914, and on the application of his administrator a committee of arbitration made an award under the Workmen’s Compensation act against C. E. Peterson & Co. which the Industrial Board sustained and the circuit court of Cook county on a writ of certiorari confirmed. This writ of error is prosecuted by C. E. Peterson & Co. to reverse the judgment.
The deceased, who was seventy years old, had worked for Peterson & Co. for several years running a coring saw, and his place of work was on the second floor of its factory. His last day’s work was done on November 23, 1914, and the claim of his administrator is that he received an injury on that day arising out of and in the course of his employment which caused his death. He was in general good health but had suffered for several years from varicose veins and six or seven years before had been operated upon but without getting relief, and he had an open sore on his leg. On November 23 he was not well, was slow with his work, had no appetite and threw his lunch away. Work stopped at the factory at a quarter past five o’clock and the lights were turned off at half-past five. Knaak did not leave with the rest of the men. A few minutes after work stopped he was seen washing at a sink. There were some pipes lying on the floor near his saw. About a half hour *328later the night watchman found him wandering on the second floor, apparently sick and dazed and unable to speak. He did not answer the watchman’s questions why he had not gone home and whether he was sick. There was a back stairway which went down outside the building, and the watchman helped him to that and part way down, when Knaak jerked his arm and said, “Leave me alone.” The watchman left him alone, telling him to hold the railing and walk slowly and holding the light for him to see the steps. However, Knaak fell when he got upon the last step but not hard. The watchman called assistance and Knaak was helped to his feet. He said it was not necessary to take him home; if they would bring him the right car he would get right on and go home. When he came out of the alley his attention was called to his shoes, which were unlaced, and he tried to lace them but looked as if he would fall over, and his companion laced them for him, Knaak saying, “Hurry up; the car is coming.” He got on the car without assistance, pulling himself up by both hands. He went home alone, the trip involving two transfers, and arrived about eight o’clock. His clothes were covered with dust and he was pale. His son asked him what was the matter, and he said, “The lights were out in the shop and I stumbled and fell over some lumber.” The deceased remained in bed in a semi-conscious condition until December 6, when he died.
The jurisdiction of the Industrial Board extends only to accidental injuries to an employee arising out of and in the course of his employment, and to, sustain an award of compensation competent evidence is necessary fairly tending to show that the employee has received an injury of that character. (Armour & Co. v. Industrial Board, 273 Ill. 590; Victor Chemical Works v. Industrial Board, 274 id. 11; Chicago and Alton Railroad Co. v. Industrial Board, id. 336.) It is proved in this case that Knaak had a broken collar-bone, but there is no evidence tending to show when, where or how he got it, except that it was probably between *329five and eight o’clock in the evening of November 23, 1914. If it be assumed that he stumbled and fell over some lumber in the shop, there is no more cause for supposing that his dazed mental condition resulted from the fall than that the fall resulted from his mental condition, but less. A man in a dazed mental condition might, because of it, fall and break a collar-bone, but the falling and breaking a collarbone would not be likely to produce the dazed mental condition. So evidence of the discovery of the deceased a half hour after the shop closed, in a dazed state, with a broken collar-bone, would have no tendency to prove an injury arising out of and in the- course of his employment. A fall resulting from a dazed mental condition' arises out of the condition and not out of the employment. . (Milliken v. Towle, 216 Mass. 293.) But the deceased was not so found with a broken collar-bone. There is no evidence of a broken collar-bone until much later. Counsel for both parties agree that the fall at the foot of the stairway was insufficient to account for the broken collar-bone. There is no evidence as to what occurred on the street car ride of more than an hour, involving two transfers, between the factory and the deceased’s home. The coroner’s jury made no finding as to where the supposed fall occurred. Then-verdict is only that they did not know whether the fall occurred on the second floor or from the bottom step of the stairs. It is a finding that the jury did not know where the fall occurred and is not a finding that it did occur at one or the other of those places.
The surmise of counsel for the administrator is that after the deceased quit work and had washed he was going to the locker to change his clothes and fell over the pipes on the floor, receiving injuries which resulted in his death. It may be surmised with as much reason that he remained, after the others had gone, to rest a few minutes and was seized with a vertigo which made him fall, or that his physical weakness by reason of sickness and going all *330day without food caused him to fall in the shop or at the foot of the stairs or on the way home. Any of these suppositions is as consistent with the evidence as any other and all are mere conjecture. Liability cannot rest upon imagination, speculation or conjecture, upon a choice between two views equally compatible with the evidence, but must be based upon facts established by evidence fairly tending to prove them.
The judgment will be reversed and the cause remanded to the circuit court, with directions to set aside the award:
Reversed and remanded, with directions.
