Each county treasurer in counties of class one not having a charter form of government shall receive and make duplicate receipts for all moneys received by the county from the federal government under the general revenue sharing law, Public Law 92-512. Each county treasurer shall separate and divide all funds received under that law, and shall establish a separate account therefor. He shall pay out the revenues thus separated on warrants issued by order of the county commission, on the respective funds so separated, and not otherwise, and for this purpose the treasurer shall keep a separate account with the county commission of such fund.
