(1) When the county commissioners of any county shall have made provision for the expenses of supporting and guarding, while at work on the public roads, a larger number of prisoners than can be supplied from that county, upon the application of the county commissioners of such county, the county commissioners of any other county which has not otherwise provided for the working of its prisoners or otherwise disposed of its prisoners, or may hereafter dispose of its prisoners, shall deliver to said county or counties applying for same, in the order of their application, such prisoners as may be confined in the county jail or hereafter be sentenced to such county jail.
