1. It shall be the duty of the collector of revenue of each county in which lands or other property of any drainage district organized under sections 242.010 to 242.690 are situate to receive the drainage tax book each year, and he is hereby empowered and it shall be his duty to promptly and faithfully collect the tax therein set out and to exercise all due diligence in so doing. He is further directed and ordered to demand and collect such taxes at the same time that he demands and collects state and county taxes due on the same lands and other properties. Where any tract or part thereof has been divided and sold or transferred, the collector shall receive taxes on any part of any tract, piece or parcel of land or other property, charged with such taxes and give his receipt accordingly. The above and foregoing drainage tax book shall be the warrant and authority of the collector for making such demand and collection.

2. The said collector shall make due return of all drainage tax books each year to the secretary of the board of supervisors of the aforesaid drainage district, and shall pay over and account for all moneys collected thereon each year to the treasurer of said district at the same time when he pays over state and county taxes. Said collector shall in said drainage tax book, verify by affidavit his said return.

3. The said secretary shall each year, within ten days after the return of said collector is delivered to him, prepare and certify to said collector a drainage back tax book containing the list of lands and other property so returned by said collector as delinquent, deliver the same to him and take his receipt therefor, and said collector shall proceed to collect such delinquent drainage taxes and demand payment therefor in the same manner as herein provided for the collection of current drainage taxes.

4. Before receiving the aforesaid drainage tax book the collector of each county in which lands or other property of the drainage district are located shall execute to the board of supervisors of the district a bond with at least two good and sufficient sureties in a sum that is equal to the probable amount of any annual installment of said tax to be collected by him during any one year, conditioned that said collector shall pay over and account for all taxes so collected by him according to law. Said bond after approval by said board of supervisors shall be deposited with the secretary of the board of supervisors, who shall be custodian thereof and who shall produce same for inspection and use as evidence whenever and wherever lawfully requested to do.
