Any county, township, city or village misapplying any portion of such funds shall be liable to the county in the full sum so contributed, and for all costs and expenses incidental, to the recovery of the same. Any person or official who shall cause or assist in the misapplication of such funds shall be deemed guilty of a misdemeanor and shall on conviction thereof be subject to a fine of not less than 100 dollars and not more than 1,000 dollars, or to imprisonment in the county jail for not more than 6 months, or to both such fine and imprisonment in the discretion of the court.
