It shall be the duty of the state road commissioner to designate some competent physician or physicians to make inspection of all camps where a convict road force is employed. It shall be the duty of such physician to make thorough investigations of the sanitary conditions of such camps each sixty days and report every inspection to the Governor, together with such recommendations as he may deem necessary; and he shall furnish copies thereof to the warden of the penitentiary, the state road commissioner, the West Virginia board of health, and the local board of health of the county in which such camp is located. A reasonable compensation to the physician rendering such services shall be paid by the commissioner.
