If by reason off any cause beyond control, and through no fault or neglect of any licensee, and when the licensee is not in default, it becomes impossible for the licensee to hold or conduct racing upon any day authorized by the board, the board, in its discretion and at the request of the licensee, may either return any fee paid by the licensee for racing on that day or, as a substitute for such day, may specify any other day for the holding or conducting of racing by the licensee.
