When certifying to the department amounts to be charged against each county as provided in section 222.73, the superintendent shall send to the county auditor of each county against which the superintendent has so certified any amount, a duplicate of the certification statement. The county auditor upon receipt of the duplicate certification statement shall enter it to the credit of the state in the ledger of state accounts, and shall immediately issue a notice to the county treasurer authorizing the treasurer to transfer the amount from the county fund to the general state revenue. The county treasurer shall file the notice as authority for making the transfer and shall include the amount transferred in the next remittance of state taxes to the treasurer of state, designating the fund to which the amount belongs.
