If the treasurer has been unable to collect any of the city taxes on the City Tax Roll on real property before the first day of March following the date when the roll was received by him, it shall be his duty to return all such unpaid taxes on real property to the county treasurer, in the same manner and with like effect as returns by township treasurers of townships, school and county taxes. Such returns shall be made upon a delinquent tax roll to be prepared by the treasurer and shall include all the additional charges and fees herein before provided; which charges shall, in such return, be added to the amount assessed in the tax roll against each description. The taxes thus returned shall be collected in the same manner as other taxes returned to the county treasurer under the provisions of the general laws of the State and shall be and remain a lien upon the lands against which they are assessed, until paid.
