Whenever moneys are available for the payment of the registered order the county superintendent of schools shall give notice, in a newspaper published in the county, or if there is no newspaper, by written notice posted at the courthouse, stating that he is ready to approve the order. The notice may list any number of registered orders of one or more districts for the payment of which moneys are available, giving the name or names of the district or districts and listing the registered orders in the order of registration for each district.
